Collision Detection?? PLS HELP!!

[Flash_Gamer]

I need to make a flash game for college, and my enemies need to kill my player dude. I have all the code working, key movement etc, the only thing I need now is how to make my player die!

Also a bonus would be if someone could help me get my special items to disappear when my player collects them...

Hi,

Collision detection is achieved with the hitTest method...

this.onEnterFrame=function(){
if(mcA.hitTest(mcB)){
trace("collision");
}
}

However, the hitTest only test for the graphics bounding box so irregular shapes other than a square will create some problems. For a game with multiple enemies, it would prob be best to store the enemies in an array and use a for loop to hitTest...

myEnemies=["enemy0","enemy1","enemy2"]

Now you can employ a hitTest against a hero movieclip with something like...

this.onEnterFrame=function(){
for(i=0;i<myEnemies.length;i++){
if(heroMC.hitTest(myEnemies[i]){
trace("Collision detected");
}
}
}

As for collecting objects, you would prob use a hitTest with a custom function for either fading the alpha or toggleing the visible property of a movieclip...

Alpha fade function...

function fadeObject(fTarget){
this.onEnterFrame=function(){
fTarget._alpha -=10;
if(fTarget._alpha<=0){
delete this.onEnterFrame;
}
}
}
//Usage.....functionName(targetObject)
fadeObject(coin);

Another option is simply to toggle the coin mc's visible property...

if...hitTest...
coin._visible =false;

hope it helps
