hitTestObject problem.

[bobet]

I am converting a as2 file to as3. I am trying to convert this. I tried this:

for (var a:uint=1; a<=10; a++) {
if (player.hitTestObject(root.["wall"+a]) == true) {
player.x += 0;
}
}

but i get this error.
TypeError: Error #2007: Parameter hitTestObject must be non-null.

Although why you'd want to += 0 is beyond me...

for(var a:uint = 1; a < 10; a++){
    if(player.hitTestObject(root['wall' + a])) player.x += 0;
}

I used +=0 to stop movement... I should use = 0....
but i changed to code and i still get that error

doh...my bad - I copied that wrong - you need the version with getChild in it :P

for(var a:uint = 1; a < 10; a++){ 
    if (player.hitTestObject(getChildByName('wall'+a))) player.x = 0;
} 

assuming you are executing on the root level...otherwise root.getChildByName...
