Hello,
i'm playing around with fred nowadays, i'm just trying to disable (i mean prevent the player from moving the ships) and then kick the ship at certains speed.
Well first i made a sexp like this :
Event: disabling ship :
-When
+has time elapsed : 1
+player use ai
+change ai class : none/alpha 1
Event : Kicking player's ship
-When
+has time elapsed : 2
+Set object speed z /alpha1 /1000
Event : Giving back the control to player :
-When
+Has time elapsed : 3
+Player not use ai
--------
I've switch the controle to ai because it looks like you can't give a arbitrary speed to the player's ship via sexp (it looks completely ignored.
Ok the only problem i have for now is the first part of the sexp :
When the control switch from player to ai , the ai move... even with a none ai class.
Is there a way to prevent that??
-
When you are doing that right on the mission start, make sure Alpha 1 is set to zero speed (in Fred, Misc Editor) and immediately after "player-set-Ai" give the "play dead" order via Sexp- "Add Goal", that's how I did it ealier :)
-
ah tanks you that should fix my problem, anyway that was quite funny to kick ai's ship into a wall at 1000 m/s
-
Ok now i've give the ai order play dead to alpha1, the set object speed do not occur anymore and the ai does'nt give me back all of the ship's control... :nervous:
Ok so after many test, it looks like the set object speed will only work if the object's ai has no goal at all
-
How do you move the player-ship ? Have you created one or more waypoints for him ? I have checked back my old mission, I didn't use set-object-speed, but instead I used "cap-waypoint-speed" (don't mind the cap, it works for fighters too). This works well, but AFAIK it requires a waypoint to move (and of course you need to give the AI-Goal "waypoint once") so that it starts moving.
use in that line of order :
- player use ai
- AI-Goal "play dead"
- AI-Goal "waypoint once"
- cap-waypoint-speed xx
Try that, it should work :)
-
i tried that, that work but it has limitation for what i m looking for :
My ship's top speed is something like 120 m/s
But for the kick effect, i try to make it go to the 500 or more m/s
that work if i doesn't give any order to ai then use the z set object speed no matter what is my ship's top speed :)
but doing that make the ai doesn't face the z axis when the kick arrive :p
-
Now I understand what you are trying to do. :) However I'm currently not sure how to achive it then when set-object-speed isn't working. But here are a lot of people that can better Fred than me, so i'm sure someone could take my place :) But AFAIK it's not possible to go above the max speed from the table at all.
-
Wel thanks you very much!
Well as i said as long as the set object speed work, it can bypass the ships max speed ;)
The only matter is that "set z object speed" do not work when you give any order to the ai councerned :)
I hope it can be bypassed.
My idea about it would be to disable the ship instead of disabling ai before the kick happen.
Didn't find sexp to disable ship.
-
Well, I don't know any Fred solution so far, but if it is really not possible to exceed the max table value, you could use a hack I once used. :)
Copy the ships.tbl entry of the vessel you want, and give the copy the new highspeed value as max velocity.
Then use the version I posted above, and either before the add waypoint goal or before the "cap-waypoint-speed" use the "change-ship-class" (located in "model and textures") and switch the playership to the copied entry. That should work, just don't forget to switch back when the player receive control again)
Improvision is your friend :)
-
That works like a charm, the only bad side is that fs2 do not load the cockpit pof when changing the ship class with sexp :nervous:
That almost work however :shaking:
Ok fixed
i ve set the initial player ship the new special ships that'll be kicked, then wait to give back control to player to give him the right ship.
It seems perfect for now i think !
Thank you very much!
-
I'm here to serve :)

Ok, now, i'm still playing with the player use ai sexp (quite interesting sexp :p )
So what i tried first was :
When
-has time elapsed : 5
-player use ai ship
-ai add goal
dock
alpha 1
Name of ship to dock with
docking point name (do not remember)
Fred did not accept to show me the dock order for the ai so i did it with notepad.
fred does complain when i load up the mission, but not freespace2 it self and it worked perfectly has intended (the ai control the players ship and dock with the ship). (Is it a big deal or not? )
Anyway my idea was :
When
and
-distance < x meters
alpha1
name of ship to dock with
-key pressed
"D"
-Player use ai
-add ai goal
-dock
alpha1
name of ship to dock with
etc...
My problem is that when i use "when" distance sexp looks grey...
What is wrong with my sequence?
-
Start out with < rather than distance. You should then be able to use distance as an argument for <.
when
and
- <
distance
x meters
-
oh cool i'll try that thanks !
-
hey... nice sexp you got there!
I've been thinking for a while now about making a player able to dock with a ship... I want to build a rearm and repair ship (like the ones in homeworld) but I had no idea on how to make the player able to dock with it.. now I have an idea of how it might go.
I ask you something, have you thought about how to make the player able to cancel the docking process? I mean like if the player was under fire.. I would like to be able to regain control of the ship again and also how to manage the priorities so that the IA does not try to fly away while under attack in the docking process.
I guess you can break the process when pressing a designated key or something, but about making the IA not trying to escape.... well that goes beyond me.
-
i was thinking about something like :
event name : ai override
When
-key pressed "U" or what ever you want
-player not use ai
That seem simple
The limitation with my docking sexp is that you can only dock with one ship at a mission.
i think we can improve to get automaticly via sexp the name and the docking point to the closest ship around the player
Maybe making event base on distance close enough by ship you can dock with can work but i don't know how perfomance impact it would have...
Experimented fredders can tell that better than me :)
Anyway, i won't be able to try that this evening,
can you try it and give me feedback :)
-
Well you can return control to the player with player-not-use-ai and key pressed.
In order to make this work you could set up a system with a variable changing between 0 and 1. Add the condition "0=variable" (start with = and add variable with start value 0) to the docking sexp and have it change the variable to 1 once it becomes true (modify-variable). Also have it reset the key you want to use for returning control to the player
Set up another sexp:
When
and
key-pressed
=
variable
1
player-not-use-ai
modify-variable
variable
0
reset-key (the one used to start docking)
Give both of these a repeat count of 999999, this should allow you to initiate and cancel docking as much as you want. I have not tested this, but I used this method to achieve a similar effect.
-
I've done that :
$Formula: ( when
( and
( <
( distance "GTT Argo 2" "alpha 1" )
500
)
( key-pressed "d" )
)
( change-ship-class
"Tf-Litebdock"
"alpha 1"
)
( player-use-ai )
( add-goal
"alpha 1"
( ai-dock
"GTT Argo 2"
"Docking Point"
"front docking bay"
89
)
)
( modify-variable @Dockvariable[0] 1 )
( key-reset "u" )
)
+Name: Dock
+Repeat Count: 999999
+Interval: 1
+Team: 0
$Formula: ( when
( and
( key-pressed "u" )
( = @Dockvariable[0] 1 )
)
( player-not-use-ai )
( modify-variable @Dockvariable[0] 0 )
( key-reset "d" )
( change-ship-class
"Tf-Litebringermk2"
"alpha 1"
)
)
+Name: Undock
+Repeat Count: 999999
+Interval: 1
+Team: 0
Well nothing happen when i press "d" at less than 500 meters from the argo
i ve unbind the d and u key in the freespace option.
I don't know where i'm wrong maybe a missuse of key pressed?
-
Aren't the dock-related AI goals usually greyed out when attempting to assign them to the player ship, even under player-use-ai?
-
sure it is :nervous:
Anyway as i said, i try first with a simple
when has time elapsed :
player use AI
ad AI goal
dock player dummy (an invisible ship in my Fred scene) with the ship to dock with
i opened it with notepad and replace player dummy by alpha1 in the formula and voilà... that worked perfectly.
But maybe that was the limit of my hack...
-
I'll try thinking about something for the last part and get back if something comes up ^^
-
Key-reset (Training operator)
Marks the specified default key as having not been pressed, so key-pressed will be false until the player presses it again. See key-pressed help for more information about what a default key is.
Note that this sexp will not work properly in repeating events. Use key-reset-multiple if this is to be called multiple times in one event.
I would at the very least start there. :p
-
Thanks you i have at least one mistake less in my sexp! :nod:
But after correction, nothing happen when i press 'd' and within 500 m with the ship :)
-
I'm still fairly certain that the player ship can't be told to dock even under AI control.
-
#Events ;! 1 total
$Formula: ( when
( has-time-elapsed 5 )
( change-ship-class
"Tf-Litebdock"
"alpha 1"
)
( player-use-ai )
( add-goal
"alpha 1"
( ai-dock
"GTT Argo 2"
"Docking Point"
"front docking bay"
89
)
)
)
+Name: Dock
+Repeat Count: 1
+Interval: 1
+Team: 0
That worked this way (after 5 seconds the AI take control of the ship and dock with the desired docking point of the friendly ship named Argo)
Don't bother the dockpoint name as "Gtt argo2" is in fact a orion ship .
I change the ship class to load a copy of the originals player ship for this mission that have special entry to allow it to dock.
The part that do not work in my sexp is the distance + key pressed trigger, i have try with just key pressed without checking distance and that did not worked either.
-
Actually I see at least two other possible causes for this
1) Don't use U and D. IIRC they don't actually do anything ingame. Which means they won't do anything for key pressed/key reset either.
2) Repeating key-pressed/key-reset-multiple are one of the very rare occasions where use of every-time instead of repeating when may be warranted. It's been a long time since I tested it but last time I did I found that the results of using the two were very, very different depending on which key I mapped them too.
-
:yes: i'll try that tomorrow evening, it's getting late here, but thanks for your help!
so may bind those key to function rarely used in freespace2 option?
-
As I recall "U" is used to target next unscanned target.
As for unused keys, I use backward target cycling keys, of course if I cannot use "1", "2", "3" and "4" keys, which are useless in singleplayer (they are used for controlling messages in multi).
-
Ok i made the change :
Every time instead of when and "n" to dock and "j" to undock
For now, it dock without problem (when the ai do not try to pass through the hull of the ship to dock with.... ai... :lol:
but that work, i think by adding a subsystem at the dock point location to the ships were you want to dock would allow closer distance and allow to use distance subsystem.
In the other hand the second part of the script didn't work, when i press "j" the ai do not give me back my ship :nervous:
I guess i ll have to find another key.
This time it"s time to sleep thank you all!
-

I just did a simple sexp to release the control using key "1" to engage IA control and "3" to disengage and it worked perfectly... when did you press the release IA control key? when your fighter was already docked with the orion or while in flight? cause that might be the problem.
-
while in flight , i was wondering too :
Why do we have to use 2 key?
I mean if we use the same key, that should work either as the conditions is : distance/variable the key could work like a switch?
-

Only the switching variable would be needed to know what to do.
The distance does only restrict the sexp from firing anywere accidentally, you can polish this even more giving a message while docking or while approaching docking distance and all those blings that might make it look like a more complex feature.
-
that's sure, but I'll debug it and keep it rather simple to use it as a template for other missions ;)
That Give me the idea that having a sort of sexp sequence library we could feed on the wiki :confused:
may be quite usefull for fredders win time while making they're mission and help the community to have more varied custom mission/campaign (note that i do not complain on the quality level of campaign and mission , i never missed one and mostly love them all ;7 )
-
I have WIP cloaknig system (nearly done) based on SEXPs and working capship piloting SEXP set, I can share them if you want.
-
i will polish the docking sexp and share it too :)
the idea would be that if someone find a way to improve the sexp he can modify the article of the sexp (would require some sort of validation anyway)
-
good idea... like a wiki article with the most commonly used (and hard to come up with) sexps, go and post this on the wiki section of the forum, it will most likely be supported by most of the members.
-
Ok , well i won't be able to post now as i must get back to work :(
I'm gonna write the post tomorrow morning
Edit :

Sounds a bit like my cookbook (http://homepage.ntlworld.com/karajorma/FAQ/fredcookbook.html). If someone wants to nick that and expand it on the wiki, be my guest.

agree it'll fit well the idea with few adaptation :)

Hi, i've been away a while cause i"ve been sick (anyway that s not the right place to talk about my life :nervous: )
I"ve give up with the key that give back control to the player, i change my sexp with a "has docked delay" and player not use ai
it result like , u press button to dock, once you have docked, you keep docked as long as you don't touch control, if you do so, you'll have full control of the ship, i prefer that way it feel more natural. the ai do what you asked and then get back to sleep.
I'm actually on another thing, i m playing with cinematics, i'm making a mission where you see a carrier jumping in, then i d like to show some fighter taking off that carrier, i have no problem when the carrier is already there at the beginning of the mission, fighters take off with no problem, but i won't if the carrier has jumped in at the beginning.
I rade sometime ago there use to have solution for that but i can't find that; so if someone have it in his mind or a link in his bookmark, it'll make me more than happy :)
-
I suppose you are using the set-camera-target or set-camera-facing-object, not sure about this but I0m thinking the first one will not work if the ship is not already in game when the sexp is activated, just place the camera a couple of meters in front of the carrier jumpoint and make it face x/y/z coordinates, then make another sexp that triggers when the carrier arrives and use the set-camera-target or whatever fits you better.
-
i didn"t explain well, sorry my english is not very good.
my problem is about that :
When you set in the wing editor the fighterbay of a carrier (let say an orion) as arrival location you end with :
If the orion is present from the time 0 of the mission (present from the begining) the fighter will arriver by the orion's fighter bay without problem.
Now if the orion arrive after 2/3 seconds after the mission begin, the fighter won't appear anymore.
-
You need to set the wing's arrival cue to something that will trigger after the Orion arrives, naturally.
-
That work like a charm.
The only complain is that when the carrier warpout it s fast like 200 m/s and need about 10 sec to slowdown if my fighter get out during those 10 sec they'll simply pass through the hull of the carrier, however nevermind.
-

never tried this before but have you changed the arrival velocity value for the wing? it might help something, though I'm not so sure.
-
Well i don't know yet where to find that option, but that sound very interesting. ;7
i ll look for it tomorrow as its quite late here.
-
Ship Editor -> Initial Status.
-
Thank you i just find it, well it do not overide the ship's table max speed so i got two solution :
-1 I wait 3/4 minutes after the carrier jump to give him time to slowdown (well that's not good for the dramatic effect)
-2 I set lower Forward decel value for my carrier
-
Well, finally i changed the decel time for the carrier, now it works greatly.
Now here something else, i don't know if anything can be done for that :
I'd like to prevent the player to move his ship in the first seconds of the mission,
It works well... after the first second, it seems that when i have my thruster not at 0 on my stick, the ship will move untill fred trat the sexp.
My actual solution is to swap player's ship with a copy with a set max speed of 0 and that works, but i would like to find a cleaner solution as fighter room's in the tables are not unlimited.

You could just use "player-use-ai" and "play dead". Then set up another event with "player-not-use-ai" with the delay you want.
-
That was done, but it looks like 0 seconds happens after 1 seconds for freespace2.
-
There is a tickbox in the Mission Notes editor to start the player under AI control.
-
Oh that's great then, i'll look for it tonight!
-
After trying yesterday the player start under AI control things yesterday, i got worst, the AI take the control form the beginning that's OK but even with an AI order triggered by when has time elapsed 0, the AI will do what it want for the first second and then apply the sexp.
So from that, i decided to sacrifice one ship entry by creating a copy of the player"s ship with a max speed of 0 but when i swap the player's model with the change ship class, the cockpit simply disappear, they have both the same cockpit, and it doesn't disappear when the ship is under player's control :nervous:
So i may have been beyond what those sexp are designed for? ;)
-
OK do you have the following done:
Player start under AI control checked
Initial player speed 0
Initial player order play dead
If you do and the ship is still moving try an event with a repeat of 9999999 and delay of 0 with set object facing object (add a waypoint where the ship should face) and set object speed 0
-
Ok i will try that, if i can save table entry (as i'll have to repeat it for each playable ships) that's perfect.
I'll try this after my job's time. ;)
-

I think I'm going to have a look at that tickbox then. If it can't avoid that happening I don't see much point in it.
-
Well the point is the very very firt seconds as when the sexp are executed, it s respected (following waypoint at a speed of 1)
the sexp is trigered by ime elapsed 0 but i guess for fs2 open : 0 seconds =init 1 seconds=0 .
I will try to break the ship's legs so it will not run far away the first seconds.
Edit :
I m getting closer to it, so i broke his leg (set engines integrity to 0 in the ship editor)
Now i got to set it back @ 100% later, the new issue with that is that set subsystem strengh sexp invoke a support ship and is not something transparent.
i m looking for something else to fix transparetly the engines in fred
-
Too bad i can't sabotage a subsystem with negative value :p
-
Yeah I know, what I said is that if the tickbox can't prevent that from happening it's basically worthless.
-
I see, something that disturb me a bit is the presence of both repair subsystem and set sbsystem strengh i mean : if the repair subsystem call for a support ship, why does "set subsystem strengh" act exactly the same? i don't see the difference between them.
If set subsystem strengh simply set directly the new subsystem strengh value that would make sense no?
-
Those sexp now work as intended , that's perfect,
-
OK,
Hi again everyone,
I'm actually working on a sexp sequence that allow the player to reload it's weapon without support ship (we have no support ship yet, and planned that fighter and bomber have to come back to the closest carrier to reload.)
It's working for now, but I'm looking for a way to improve it,
For now it check the distance to a given subsystem
"evertime
<
distance to ship subsystem
50
etc..."
What is bad right now with this, it's that you just have to run to the hangar bay at full speed and you get instantly reloaded.
I'd like to check more things in order to trigger the rearm thing :
So I've added a speed checking , but what i'm looking for to finish it, is a time check,
Basically from what i understood "has time elapsed" is based on mission time,
I d like to create a sequence that check :
when alpha 1 is Under a distance of 40 m
and alpha 1 speed under 30
those two condition where true for 5 second
then rearm.
The first two condition are checked already, but the last one, i did not find solution yet , Any idea?
-
Well it's 5:30am so this may not come out too well.
You probably need 3 events and a variable (call it rearm)
First one:
When
->or
-->distance to ship subsystem alpha 1 > 39
-->current speed alpha 1 > 29
->modify variable rearm 0
repeating 99999999 delay 1
second
when
->and
-->distance to ship subsystem alpha 1 < 40
-->current speed alpha 1 < 30
->modify variable rearm rearm + 1
repeating 9999999 delay 1
third
when
->rearm > 4
-> do your rearming
-
That Seems a clever way to adress the issue.
Is there a limit of sexp that can be stored in a signle mission?
right now i ve a lot of sexp in my mission's template and yeet nothing happen in those mission :p
-
I'm doing it right now, what i don't get is wich sexp to use to check a variable value (i mean for the last part
Oh i think i got it!
-
Variables can be checked using the same operators you would use for fixed numbers or strings.
-
This sounds like something Diaspora would benefit from...
-
Given that FUBAR and Karajorma are on that team, I'd say they know about this already.
-
Resurecting this thread from ashes, key pressed does not work in multiplayer coop.
I was working on a sexp sequence that increment a variable by +1 each time the player press the key , each number from 1 to 5 is used to "select a ship class " then when you fill some given condition your own ship get swapped by the one you selected, when the variable get to 6 the the sequence reinitialise it to 1
Is there another way to achieve that kind of stuff with using something else that key pressed, i mean is there any possibility to use some sort of communication menu instead ?
I may create 6 special subsystem in a ship's fighterbay and check distance for the selection but i'd prefer a more civilised solution.
-
Can you post the actual event here in code tags?
Also, key-press will only work for the host in multiplayer, as other players just cant send any sexp information back to the host.
-
Well it works fine in solo, the same doesn't work in the multiplayer version of the mission
everytime
->key press "B"
->modify variable
"ship select"
+1
->Send message
Command blah
blah
Fighter selected
then i have
When is event true delay (event abobe with delay 1)
key reset B
all with repeat count of 20000
The problem is that i do not even receive the message in multiplayer, so it seems to me that the key pressed sexp do not work in coop mission.
-
That's because the variable you're using isn't a network variable. Edit the variable and choose the "Network-Variable" option. It should work that way. If it still doesn't, either open the mission file with notepad and paste the event in question here or upload the whole mission as an attachment.
-
The network variable is ticked already ;)
But normally even if the variable is problematic, the way the sequence is done, i should receive the message no?
As it is for a total conversion sending the mission would be frustating ^^
Anyway here it is :
(http://tof.canardpc.com/preview/7247c5c9-d846-4888-87ed-1ebd034df6a1.jpg) (http://tof.canardpc.com/view/7247c5c9-d846-4888-87ed-1ebd034df6a1.jpg)
The variable itself

-
You don't need that second event, just dump that key-reset in the same every-time. You'll also need to use key-reset-multiple, as it's designed specifically for events which get called multiple times.
-
It use to be in the same everytime at the beginning but when i tryed the first time i moved it away to ensure the problem do not come from there :)
But it s part of the same everytime right now.
-
Can you please post the mission? If you don't like showing your content to the public, feel free to PM me with it. There's only so much I can do without looking at the mission file.
-
No problem :D
[attachment deleted by ninja]
-
I have no idea what's causing this. I even turned the thing into a when with a large trigger count, switched the variable to a non-network, and even mapped it to some other key. Nothing worked.
We'll see what someone more experienced will have to say on this.
-
^^ Did you managed to use keypressed in coop mission to work before?
-
The key-pressed SEXP has never worked and possibly may never work in multiplayer. The problem is the whole server/client issue again. All SEXPs run on the server, the client never even enters that section of the code at all. When a SEXP is fixed to work in multiplayer it means that the server sends a notification to the client telling it that the server has done something and that the client should do the same thing too. So as you can see everything SEXP related is basically a case of the server telling the client what to do.
This is an issue with key-pressed as the server doesn't have the information needed in order for key-pressed to work. It only knows which keys have been pressed on the server. If the host is running the server that means only the player on the server's keys are processed. In the case of a standalone-server it means nobody gets their keys processed, not even the host.
In order for key-pressed to work in multiplayer the server needs to have all the information it needs already present when the SEXP is checked. Now I could simply fix it so that the players send all their data to the server every key-press but I'm worried about the sheer amount of data that would involve sending. As a matter of fact, I was looking into a solution yesterday of having the server notify the clients which key-presses it is interested in and having them send information back only if one of those particular keys is pressed.
While I might be able to code that, I'm currently busy with Diaspora stuff now and it will be a week or two at the very least before I have time to look at it again.

I see, well that's really nice from you to fixed that, we do not plan to release anything before 6 mounth at least anyway so you do what you have to do, i have no problem with that :)
However one more question , if i understand what you said, it should have worked, when i made my test i host the server (player/Server ie not dedicated ) and played as alpha1, or i guess the game by default do not treat key pressed in multiplayer.
For those kind of script i wonder if a comm like menu (done in lua? ) called by a common key would not be better than waiting for a key to be pressed (as most of key is binded by default) i mean it bugs me a little to "override" an existing key, if i wanted to make for exemple a script that transofrm my target to an electric sheep (why e sheep i do not know :p ) by pressing b for exemple well...
Anyway it is certainly not a real issue as most fredders untill now could do it with key pressed.
