Title: How to set up a key prompt?
Post by: HLD_Prophecy on October 19, 2016, 09:45:34 am

Hey all!

So I'm trying to figure out how to set up a Y/N type key press prompt for the player. Subtitle Text will display prompting the player to press Y or N, and whichever key is pressed will determine the next chain of events (so if the event "key pressed is N" is true, then a certain subtitle text will display and a ship will warp in a few seconds later, but if the event "key pressed is Y" is true, then a different subtitle text will display and the ship will warp in right away.

Anyone know how this works?

Thanks!

I'm at work, so I'm doing this off the cuff without reference to FRED, but it will look something like this.

Code: [Select]

SomeEvent
-When
--(some trigger, doesn't matter.. just whatever you want to start the keypress event)
--show-subtitle-text [your text (Press Y for this N for that)]
--key-reset (This causes FSO to see those keys as unpressed from this moment until they are pressed)
---[the keys you want to use for yes/no]
SomeEvent 2 (also use this event with is-event-true-delay for the ship arrival trigger)
-When
--And (so that this event only triggers after the event above)
---is-event-true-delay[SomeEvent]
---key-pressed [whatever key for yes]
--clear-subtitles(to clear the instruction subtitle)
--show-subtitle-text
SomeEvent 3 (also use this event with is-event-true-delay for the ship arrival trigger with a delay)
-When
--And
---is-event-true-delay[SomeEvent]
---key-pressed [whatever key for no]
--clear-subtitles(to clear the instruction subtitle)
--show-subtitle-text

Now if the ship to warp in is the same ship for both yes and no with the delay being different, then you can add something like this.

Code: [Select]

SomeEvent 4 (use THIS as your ship arrival cue)
-When
--or
---is-event-true-delay(SomeEvent 2)
---is-event-true-delay(SomeEvent 3)
--Do-nothing

Then add set-arrival-info to SomeEvent 2 & 3 to modify the arrival delay.

Awesome, thanks! I'd tried it before and came out with pretty much this, but I didn't have the key-reset.

I will try it when I've got the time and reply again if it doesn't work, but I can't see why it shouldn't. :)

Okay, I've tried it - pressing Y works perfectly! But pressing N does nothing. The events are set up right... can you help me solve this?
