Multiple hitTest?

[jozojozojozo]

Okay, so i'm making a tank game, where you shoot missiles etc, but i'm having a problem..

How do you make it so that when it hits a object, the object will preform the script?

So far, the hitTest code is

onClipEvent (enterFrame) {
if (this.hitTest(_root.bullet)) {
_root.bullet.spd =0
}
}

Although that does nothing at all, I know its because there are multiple bullets, but what would I call the bullets? :S

Thanks.

Either:
- Use a for loop. This is the best way.
Or
- Make a hitTest for each bullet (bullet1,bullet2 etc).

Yeah, for loops are amazing. They make things so convenient.

for (init; condition; next){
	// stuff
}

Usually you would use a variable such as i.
e.g.

for (i = 0; i < 5; i++){
	trace(i);
}

What that essentially does, is make i = 0, then keeps incrementing (i++) the variable i while it satisfies i < 5.

If you place this code into a new flash document, in the output box, you should see:

0
1
2
3
4

Sorry, I'm not really sure what goes where..

Oh yea, instead of 5 i changed it to 500000, don't try it. :(

Lol, yeah perhaps I should have mentioned the dangers.

Just don't try leaving the loop blank like this:

for ( ; ; ) {

}

That puts it in an infite loop and will crash Flash. If you feel the need to try it out, save first!!!

Unless you're using ActionScript 3.0 ;)

Okay thanks, but I have no clue what to do lol :P

So far, I have bullets, and I added this code to a object:

onClipEvent (enterFrame) {
for (i=0; i<5; i++) {
trace(i);
if (this.hitTest(_root["bullet"+i])) {
_root["bullet"+i].gotoAndStop(2);
}
}
}

That is what I thought would work, but it didn't, please help ;C

Your problem here is probably the instance names. You may want to be using attachMovie:

onClipEvent (enterFrame) {
	for (i=0; i<5; i++) {
		trace(i);
		bulletFire(i);
		if (this.hitTest(_root["bullet"+i])) {
			_root["bullet"+i].gotoAndStop(2);
		}
	}
	function bulletFire(n:Number):Void {
		this.attachMovie("BulletMC", "bullet"+n, this.getNextHighestDepth); // "BulletMC" is the name of the bullet movie clip which must be exported for actionscript in linkage. 
		// This will create a new instance of BulletMC at runtime and give each one an instance name of bullet+n (n is equal to i). This means you will have bullet0, bullet1, bullet2, etc.
		// Note: this alone will not do it, it's just an outline. Look up attachMovie in flash help (F1).
	}
}

Hopefully this will give you some hints (fingers crossed). ;D
