Hello,
could someone please help me to understand how collision
detection works in JS? I can't use jQuery or gameQuery - already using prototype - so, I'm looking for something very simple. Not asking for complete solution, just point me to the right direction.
Let's say there's:
<div id="ball"></div>
and
<div id="someobject0"></div>
Now the ball is moving (any direction). "Someobject"(0-X) is already pre-defined and there's 20-60 of them randomly positioned like this:
#someobject {position: absolute; top: RNDpx; left: RNDpx;}
I can create an array with "someobject(X)" positions and test collision while the "ball" is moving... Something like:
for(var c=0; c<objposArray.length; c++){
........ and code to check ball's current position vs all objects one by one....
}
But I guess this would be a "noob" solution and it looks pretty slow.
Is there anything better?
