[CS3] Isometric game: object visibility

[renderhjs]

you can use the Shape container if you want the fastest container its usefull if you dont need mouse Events for example for that container. I use the shape container often for 3d rendering.
from heavy to light:
MovieClip > Sprite > Shape
sprite is the fastest that still accepts mouse events - but like I said if its just for visual data better use Shape.

About clearing...if you already use:

this.graphics.clear(); 
this.graphics.beginBitmapFill(this.global.imgMgr.p layer[spriteCounter]);
this.graphics.drawRect(0,0, 80, 120);
this.graphics.endFill(); 

it means that you clear the graphics container anyway - why not drawing then all of those "this." containers into 1 big container like:

var g:Graphics = this.graphics;
var cells:Array = [....holds the cells information....];
cells.sortOn("y");

g.clear(); 
for (var i:int=0;i<cells.length;i++){
    g.beginBitmapFill(cells[i].global.imgMgr.player[cells[i].spriteCounter]);
    g.drawRect(0,0, 80, 120);
    g.endFill();
} 

cells.sortOn("y"); sorts the sprites based on their y-position assuming that the cells array is the one holding either objects or classes with y- properties of the positions. For a propper sorting assign each tile its depth value ahead and the sort it here. Not sure how you sort now as there are multiple ways of doing.

PS: the character is from the ffanimation engine and the fase textures

I noticed that right away- but even texturing might be interesting from the perspective of someone who writes a engine- like what about shadow casting, faking texture baking ect. dont think that strictly in categories -thats what so many people already do
