In need of help scripting explosions...

[Mlucci4036]

Let me try to explain what I was going for here. I've made a location my mod that is essentially a battle between two factions. They are in a stalemate, and there is essentially this large No-Mans-Land between their two trenches. I want to script a sequence that will cause the player to be attacked by mortar and shell fire when her enters this cubic activator, much like the area outside of Nellis Airforce Base when entering the area for the first time. I want this to occur ever time the player enters the activator, but stop when he exits it.

 

I'm not sure quite how to do this, is there anyone that can help me?

 

Here is a reference photo of the location I have made.

Just study how it works for Nellis AFB and adapt it to your own needs. :)

I tried, but I just couldn't figure it out for the life of me! There are so many variable in the Nellis Artillery scrip that I have no idea what to edit!

Take a look at script for NellisArtilleryActivatorEntrance activator. When player enters (begin OnTriggerEnter) some vars are set for begin gamemode block.

Then game randomly creates explosions near player (I think rTarget is set to be player reference somwhere in the script)

					
                                        set fRelativePos to rTarget.GetPos Y + fRandom
					ArtillerySourceMarker.setPos Y fRelativePos
					set fRelativePos to rTarget.GetPos X + fRandom
					ArtillerySourceMarker.setPos X fRelativePos
				        endif
				set angle to ArtillerySourceMarker.GetHeadingAngle NellisMainGateREF
				ArtillerySourceMarker.SetAngle Z angle
				ArtillerySourceMarker.PlaceAtMe FXNellisArtilleryStrike01

Explore this script.

I just spent a good deal of time experimenting with the script, but still no luck. Correct me if I'm wrong, but shouldn't this script run the sequence?

Wow, that sure is a big script :laugh:

 

Have you tried something a bit different perhaps? Not as elaborate as what the vanilla game does, but it would be something. You could have a timer script (linked to a quest I'd say) that, every once in a while, will place an explosion by the player. You'd make it so the quest starts when the player enters the trigger box, and stops when they leave it.

 

You could try a script like this. It's something I altered from a script I have in my own mod I'm making at the moment.

scn TimedExplosionScript

Float Timer

Begin Gamemode

if (Timer <10)
   set timer to timer + GetSecondsPassed
Else
   iMod ExplosionInFace
   player.PlaceAtMe MineFragExplosion
   PlayerREF.Say Hit
   PlayerREF.DamageActorValue Health 50
   Set timer to 0
Endif

End

This would make it so every 10 seconds or so (can be changed of course) an explosion will blind the player. The player will yell in pain and receive a bit of damage. Then the timer will reset and start again.

 

As I said, not nearly as elaborate as what you had in mind, but it could tide you over in the meantime :smile:

 

EDIT: If I remember correctly the explosion effect from the artillery is FXNellisArtilleryStrike01, so you could replace MineFragExplosion in the script with that and see how it looks.

Thanks! Thats actually very useful. :smile:

I took the script and tested it using Begin Gamemode, and the Artillery strike does work. The only problem is, when I change it to Begin OnTriggerEnter Player, the sequence will not run.

scn BigAppleArtilleryScript

Float Timer

Begin OnTriggerEnter Player

if (Timer <10)

set timer to timer + GetSecondsPassed

Else

iMod ExplosionInFace

player.PlaceAtMe FXNellisArtilleryStrike01

PlayerREF.Say Hit

PlayerREF.DamageActorValue Health 10

Set timer to 0

Endif

End

Any Idea how to get it to run when the player enters the Trigger, but stop when he/she leaves it?

Well, that's why you need to make it run with a quest. Gamemode is what makes the timer work.

 

So make a new quest (just any ID because it won't show up, for instance ArtilleryQuestThingy), priority 55, start game enabled, script processing default. Save it and open it again, then assign the timer script from earlier to it. Now make your trigger box wherever and give it a script like this. I'm not on my computer at the moment so it's off the top of my head... Just got up so I haven't had my coffee :laugh:

scn ArtilleryTriggerScript


Begin OnTriggerEnter Player

   StartQuest ArtilleryQuestThingy

Begin OnTriggerLeave Player

   StopQuest ArtilleryQuestThingy

END 

Something like that should do it. In my mod the quest starts when the player equips and unequips a piece of apparel so you could try that too. But hopefully the script above should do it. Good luck! :thumbsup:

 

EDIT: On second thought I guess it shouldn't be start game enabled because then strikes will follow the player everywhere in the game, haha :laugh: so just don't tick start game enabled and let the trigger start it instead.

Alright, thanks for the help. I'm still tweaking that second script to work properly, but despite the 1st script being hooked to a quest, wouldn't the Begin Gamemode command cause the artillery to fire all the time despite being attached to a quest?

[Jokerine]

That's why you don't set the quest that holds the timer script as "start game enabled". The quest will not start (and therefore the artillery strikes won't fall) until the player enters your trigger. Then while they are inside the strikes will fall until they exit the trigger and the strikes will stop (until they enter the trigger box again).
