I understand the basic movement in the first part but i just don't know what everything else means and why you put it there. Great tutorial thank you for doing it.

Thank you for this (atleast this far ;P) wonderful tutorial. It's just that i got a little problem. If i try to run the game (after i added the trace and the hitTestObject thing) i only get hit if i shoot at the same time as i am hit, with mcMain... And if i just stay still with mcMain, the bullets don't hit, they go straight through mcMain. Hey!

I know the hardest part of learning and teaching ActionScript or any kind of programming language is to learn how the code actually works. I'll try to explain it as best I can. In ActionScript, you can assign certain MovieClips that are already placed on stage, a variable name. For example, if you put a MovieClip with a instance name of <code>mcThing</code> onto the stage without using any code, you could give it a variable name in code like so: <code>var thingVariable:MovieClip = mcThing;</code> This way, you can access the MovieClip's properties by using either <code>thingVariable</code> or <code>mcThing</code>. This is sort of how the <code>bulletTarget</code> works, except more dynamically. In our for loop, we define the limit as <code>i<_root.bulletContainer.numChildren</code>. This means that this loop will run through for every single MovieClip that is in the <code>bulletContainer</code>, which would just be for all of the bullets. <code>getChildAt()</code> simply means that <code>bulletTarget</code> will be the MovieClip that is at the certain index level as the <code>i</code> variable. Index level isn't too important, it's similar to <code>depth</code> in AS2. Hopefully, this is a bit of help to you. Good luck on learning ActionScript! Hey Danilo.

I see you handled this creating the "bulletContainer" var and using the loop "for(var i:int = 0;i<_root.bulletContainer.numChildren;i++)" My problem is, I know this works, but I don't know how, I mean, I don't know how the "bulletTarget" var works, so it would be appreciated if you could explain this. Anyway, thanks a lot for all the help :) Hi, I’ve been learning AS3 for a while, and the most important thing I could never figure out is how to code bullets and those things, mainly because there are always many bullets and I don’t know how to code them so they hit the enemy.
