Trouble with a few basic things

programming flash

I’m having a real hardtime with several things that seem relatively easy to do in AS2 with AS3. I can’t seem to find any tutorials in AS3 to create a very basic RPG with making maps, some simple tiles and collision, and battle-screens. Everything is in AS2.

What I have been trying to do for the past 2 days with little to no success is:

Create Collision Detection for human-controlled movieClip and also randomly moving movieClips. The former is most important, obviously.
*And how to implement the classes for it in the best organized fashion.

Create Classes Dynamically from MovieClips and Sprites in the Library.

//The name of the automatic class for a wall is: Wall
var wall = new Wall();

I’ve tried using a loop with getDefinitionByName, but it kept giving me the 1065 error, that something isn’t defined.
The last attempt at it looks like this kind of:

        public function doIt(howMany:int):void
        {
            for (var i:int=1; howMany>i; i++)
            {
                //var BlockClass:Block;
                var BlockClass:Class = getDefinitionByName("Block" + i) as Class;
                block = new BlockClass();
                block.x = i * 10;
                addChild(block);
            }
        }

I was trying to do that in attempts to also make the Block’s go into an array that maybe I could also loop on EventHandlers for collision detection; but when I isolated that attempt of code, it didn’t work at all, so I won’t bother posting that.

So basically I want to make a reusable code for collision on tiles or anything that can at least get me started on how to properly use Collision Detection in OOB.

And how to create classes dynamically in loops and how to call on them.

I am pretty new at this sort of stuff for Flash, so linking me to adobe, won’t help. I’ve read and digested everything they have and it was no help.
