Title: warp in model now loading from pof
Post by: Bobboau on October 22, 2002, 02:44:10 am

as you can see in the image below I have gotten the warphole model to render as it should in game, this will be most usefull for TBP, but it does offer an improvement for normal FS as well, I still have to implement LOD and as you can see in the image I forgot to turn off backface culling (fixed it right after takeing the pic), but this is one of the things that we have wanted for a while, and the code I used can be used for other such cool efects like 3D explosions and such
(http://freespace.volitionwatch.com/blackwater/newsubspace.jpg)
I will commit this as soon as I get it all ironed out
(I may save my changes and start from a clean update becase I have developed this problem were the game has a 40% chance of hard freazeing on stratup, it didn't start doing this untill after I commited my last changes so I'm worried that this may be something that was introduced around that time, by me or someone else)

Btw, how did it used to work?

ani mapped onto a flat polygon, I think.

This allows, I reckon, for better subspace 'tunnels' to be modelled (as the warpout pof)

You think we could have 3D jump point?

Most definitely a good think for TBP, B5 cone-like jump point.
There at least two different effects though... one seen in A Call to Arms-movie and another in the series and ItB. And a new one seen in The Legend of the Rangers.

the way it's setup, you can have any model that falls within the normal pof limetations, and any warpin/out (these can still be diferent) ani mapped to it, I actualy made a warp model for TBP for testing though it could use some work,
is there a quick vidio of a ship exiting hyperspace that I could examine to try and reproduce for the effect

Bob that is the most USEFULL thing u did for TBP with source code;7  -- try it with a cone one but with a animated texture that make like it is changing alpha channel from 0% to final blue efect:)

Five short avi captures are soon up. Wait a few mins.

OK, here are ITB captures. (http://koti.mbnet.fi/~fury/misc/itb.zip)

And Bobboau, don't you have ICQ? Communication would be tad easier. :)

looking at those clips I may have to add a step in frot of the current warpin effect were it has a cone of beam like objects and the warp glow that fade just as the warp model opens,
might it be a good idea to scale the ship models as they are going through the effect (I think I can do that now)

maybe you could even make it so, that you can´t see ships from behind the warphole.

right, now.

you just see a ship appearing, and in case of scale, you would see a ship "grow".

and in the case it has to travel a bit while it grows like in TBP

Disable collisions or else u know what will happen to ships behind the warphole.

You could use the dot product of the direction of the cone and the vector from the cone start to the viewing ship to determine if it should be seen by checking the resulting angle against the average angle of the cone.

By the way, would it be possible somehow define jump anim size regardless of ship's size?

I mean, mostly only military ships have jump capability in B5. It would add a lot of atmosphere to our mod if we could simulate this in the way that one jump point is used by numerous ships.

That would be very cool for TBP and other mods.

Post by: Anaz on October 27, 2002, 03:42:59 pm

I think I know how to do that just using this...
you make a big invisible cube, and have it warp in, and in the space where it warps in, you just have all of the ships that you want to appear come out with no warp effect.

Title: warp in model now loading from pof
Post by: Solatar on October 27, 2002, 03:46:49 pm

Yeah, but make sure the cube has a "no_collide_invisible" tag. Or it might look funny.

a perhaps more usefull way would be to have to the effect appearing at an user set spot at a user set size, sort like actually having jumpoints forming on events.

so you could set some "jump points" sort like jump nodes, but where these actually has an effect that can be activated by an event sort like this

sexp

when distance <100
-form jump point
-ship(to get an angle)
-duration in ms
-size


if the ships would be warping out would be up to the mission designer, so he could make a simulated faulted jump attempt.

Post by: Fury on October 28, 2002, 04:41:20 am

Hmh, how about we can define that multiple ships are actually using a single jump point? Let it be like "Wings", you form a group of ships that uses same jump. Naturally this disables ship specific jump for selected ships. Much like it does when forming wings.

In "jump group" editor you can also define if a group arrives through a single jump point or if it is leaving through a single jump point. If the group arrives, it disabled arriving warp in area in ship status window and if group leaves it disabled warp out area in ship status window.

Also, I hope this would support friendly, hostile, unknown and neutral ships in same jump group.

All you need is to place ships in fred2, make them as "jump group" and they will appear in-game in their respective places. Jump point is as large as is necessary, so it is also important not to make groups where ships are 10km away each other. ;) That would make an impressive jump anim. :D


Example:
Friendly ships A and B arrives to fight off enemies through same jump point.

Hostiles are running and Friendly B is chasing Hostile A, Hostile A jumps and Friendly B jumps after through SAME jump point.

Edit: Propbably not the best idea... :rolleyes:
