Killing an Actor after 5 on screen?

TouchTiltGames

Ok I've got a gun and it's shooting bullets on the screen, but I want to kill the first bullet shot of the 5 so there's only ever 5 on screen.

So with my limited knowledge, but trying to grasp this: I've setup a Rule and attribute..but then do I setup an interger? I was trying an Attribute like: game.BallCount > 5 then Destroy..but that doesn't seem to work

Thanks in advance!

well. lets say you shoot 1 bullet every second. so, in 5 seconds, you would have 5 bullets on the screen. the problem is, if you continue shooting, you would have 10 bullets in 10 seconds and so on.
but if you know, that you spawn 1 bullet every second. why not put a timer inside the bullet, that says "after 6 seconds - destroy"
this way, you would only have 5 bullets on the screen each time.

Hey Nulo, That's a good point, thanks, but this is more of a strategy/physics game where you use the bullet/balls that you shoot to knock stuff over. So you maybe thinking for a bit before you shoot your 2nd shot.

You know what, your timer idea works just fine..I can set the time to a higher number which would allow the user more "bullet time" hehe. Thanks!

Ok that's not going to work because of the nature of the game...I need to figure out how to kill the 1st ball I shot of say (5) balls...hmm...

nulo

but do these "bullets" stop at some point? or do they go until they get off the screen?
what you could do to not shoot more than 5 bullets at a time would be create a attribute "bullet_num" and give each bullet a change attribute that adds +1 the the "bullet_num"
then on the spawner of the bullets make a rule, if "bullet_num" is < than 5 spawn bullet
this way when you have 5 bullets spawned it would not spawn any more until a bullet is destroyed (which you would then do another change attribute to "bullet_num" -1)
now i have to think a little on how to make the first one get destroyed automatically.

You need to add a self.integer that is set to 1 when the bullet is first spawned. You need a RULE in the bullet actor that checks for whatever action triggers the bullet spawning to begin with. Every time that action occurs, you need to change the self.integer to self.integer +1.
The last RULE you need in the bullet is one that checks for when the self.integer exceeds 5; when that happens, destroy.
