WireParam As3

Thought on constrainable object structure:

You can have bound functions, but you cannot have bound properties.
That said, constraints should operate through bound functions
such as getX and setX.

This will enable "WireParameters" in flash like wireparameters in max.

Whenever you use addChild, the object is put on the top of the display list (highest z-index). You can use a couple different methods to manually set the index - also, remember that you have to use an index thats in bounds, you can only set an index to 100 if there are 100 other things on stage.

addChildAt(mc, 0); <= this will add to the back

addChildAt(mc, 10); <= this will add to layer 10 and bump anything already there

setChildIndex(mc, 20); <= this moves mc to index 20, bumping anything else

setChildIndex(mc, this.numChildren - 1); <= bring mc to the top

swapChildren(mc, mc2); <= switches the two

swapChildrenAt(0, 10); <= switches whatever is at 0 with whatever is at 10

Pass By Reference in AS3

Turns out, you can't do it.


var A1:Array = [1,2,3,4];
function theFunction(someArray:Array){
var otherArray:Array = [555,555,555];
someArray = otherArray;
trace("A1==" + A1);


Now, you are probably saying:
[1]: Why do this?
[2]: Why not use return value?

I wanted to make a function called: removeReferences.
Usage: removeReferences(theArray,theObject);
It would look for references of theObject in theArray and
set those references to null. Then the next pass would create a new
array where the null references would not be included.

My function still works.... But it has to be called as such:
theArray = removeReferences(theArray,theObject);

Which to me is ugly ugly syntax.
It is akin to saying: theArray = theArray.push(theObject);

Unfortunately, all the other workarounds are even uglier...

If I am going to make a particle that spawns other particles, that
could create huge memory leaks if I don't figure out resource management.
