AS3 - Is it possible to test objects in the same array against each other?

Question

I am making this project that allows the player to push objects. I can test the player against the object array just fine using the "for" loop and I can move the objects around.

What I want to do now is test the objects against each other and have them move each other as well. Like, I want to push a block with the player and then push another block with the block I'm already pushing.

The blocks are all pushed into their own arrays, so how could I test them against each other?

Answer 1

Sure, you can place everything in the same array and use two for loops:

for each(var a:Entity in array)
{
    for each(var b:Entity in array)
    {
        // Objects can't collide with themselves.
        if(a == b) continue;


        // Check if a and b collide and do something.
        //
    }
}

This example code assumes that Entity is a base class for your objects that can touch each other; all of which are listed within array.
