256 Levels Or Recursion?

Try to rewrite that code without recursion. Does every ClearPoint() action have to have its own while() loop? Maybe one is enough, so you could have another function doing the loop and call ClearPoint() in that, something like that:

function DoClearPoint(myarrGrid,x,y) {
intCount = ValidCount(arrGrid, x, y);

while (intCount > 0) {
switch(Math.round(Math.random() * 1234) % 4) {
case 0:
if (ValidMove(arrGrid,x,y-2) > 0) {
arrGrid[(y-1)*W+x] = 1;
ClearPoint(arrGrid,x,y-2);
}
break;
case 1:
if (ValidMove(arrGrid,x+2,y) > 0) {
arrGrid[(y*W)+x+1] = 1;
ClearPoint(arrGrid,x+2,y);
}
break;
case 2:
if (ValidMove(arrGrid,x,y+2) > 0) {
arrGrid[(y+1)*W+x] = 1;
ClearPoint(arrGrid,x,y+2);
}
break;
case 3:
if (ValidMove(arrGrid,x-2,y) > 0) {
arrGrid[(y*W)+x-1] = 1;
ClearPoint(arrGrid,x-2,y);
}
break;
default:
break;
}
intCount = ValidCount(arrGrid, x, y)
}
}

function ClearPoint(myarrGrid,x,y){
// code without recursive calls
}

You would start the process with DoClearPoint() and handle the calls to ClearPoint() in that. This way you won't see the recursion level warning because there is no recursion.

I believe there once was a way to open up a compile SWF and replace some bytes to increase the recursion levels – maybe, or I could just be confused about the delay before the "slow script" message was shown.

But for some reason I think that went away with recent versions of Flash. Or maybe not. I just don't know.

But the best solution would be to rewrite the function. I'm not sure I can really give any advice on that end of it – I don't really understand what that code is doing, but that will probably be the best approach.

a.) W is width, H is height, S is the size of the blocks which are drawn.
b.) all i need to know is how to bypass the error. It is used to draw mazes with sizes anywhere from 27 to 123. It's when you get pass the 40 stage when the error starts occuring.

What's W?
