Variable Help

[DragonFruit-Rock]

NOTE: I WORK IN ACTIONSCRIPT 2, NOT AS3. THANK YOU.

Ok, I really should be able to do this, but whenever I do try, I fail miserably. My problem is combining hittests and variables. Right now I'm just screwing around with a little control design that I started a while back. Here it is so far. See that little 100 in the top left corner? Thats your little squares health. Whenever you hit one of the little black lines, or bullets, I need that number to go down by, lets say 1. I know how to change it and stuff, so it really dosen't matter. Ok, since all the other code is irrelevant il just post the hittest stuff.

onClipEvent (enterFrame) {
if (hitTest(_root.bullet)) {
_root.health-1;
}
}

Honestly I'm a disaster at hittests, but ive tried many tutorials and they dont seem to help, so Im asking you guys. I know this is quite a basic code, but i just cant do hittests. Anyways, ive done everything i know of to make the code work. I've givin the bullets the instance name bullet, ive made the 100 a variable the the place it appears in is a dynamic text box and all that, and you get the idea. Just if you can, please help.

Thanks in advance,
DFR

onClipEvent (enterFrame) {
if (this.hitTest(_root.bullet)) {
_root.health -= 1;
// OR _root.health--;
}
}

That should work.

I am pretty sure that you write -=1 or -- instead of -1 when changing a varable.

it didnt. I rechecked all the things like instance names and such, but still nothing.

Can anybody help please??????

Are you sure the bullets firing at the box are just called 'bullet' or are they bullet1, bullet2 etc through duplicating or what? Becuase if so you need to chuck a for loop in the hit test code.

Can only one bullet be on the screen at the time? Otherwise, that is going to be problematic.

Like the others suggested using 'var -1' wouldn't change the variable. Use the decrementor operation.

If that doesn't fix it, then put a trace in that condition to see if the hitTest is working, or if it's a problem with the decrement or the variable showing up in the textbox.

i think u have the hpbar thing wrong i did that in my engine that i just finished lol

if u dont set

_root.health=100

somewhere in your code

and also in the var for the hpbar dynamic text
it wont work

Well first of all it should be -= 1 not -1. Secondly, all the bullets cannot be called 'bullet' which is where your problem lies. You are only, presumingly, testing against 1 bullet which has the name bullet and the rest are duplicates with different names. You're going to have to do a for loop, I suppose. However, it may possibly cause lag depending on how big it is.

You're going to have to do a for loop, I suppose.

That might help you. Here's the tutorial for the 'for' loop.

Awesome. Thanks guys, I need to stufy that loop then!
