在AS3雪碧的最大尺寸是多少？ [英] maximum size of a sprite in as3?

问题描述

有一个上限，以在AS3精灵的尺寸/闪存10？

Is there an upper bound to the size of a sprite in as3 / flash 10?

我知道位图数据有其局限性 ...

推荐答案

看来，这xScale等和yScale不得超过为0x8000 ...

it seems, that xScale and yScale may not exceed 0x8000 ...

尺寸本身也似乎被绑定...我发现了一个极限0x6666660 ...

size itself also seems to be bound ... i found a limit 0x6666660 ...

这里的code：

package {
    import flash.display.*;
    public class Main extends Sprite {
    	public function Main():void {	
    		var size:Number = 1;

    		var s:Shape = new Shape();
    		s.graphics.beginFill(0xFF00FF);
    		s.graphics.drawRect(0, 0, size, size);

    		var old:Number = 0;
    		while (s.width > old) {
    			old = s.scaleX; 
    			s.scaleX *= 1.1;
    		}
    		trace(s.width.toString(16));

    		size = 1;
    		s.scaleX = 1;
    		while (true) {
    			size *= 2;
    			s.graphics.clear();
    			s.graphics.drawRect(0, 0, size, size);
    			if (s.width < 0) break;
    		}
    		var min:Number = size / 2;
    		var max:Number = size;

    		while (true) {
    			size = (min + max) / 2;
    			s.graphics.clear();
    			s.graphics.drawRect(0, 0, size, size);
    			if (s.width < 0) max = size;
    			else 
    				if (max - min < 1) break;
    				else min = size;

    		}
    		trace(s.width.toString(16));
    	}
    }	
}

没有找到关于它的任何文件...所以你甚至可以让你的计算机上的其他结果...

didn't find any documentation about it ... so you may even get other results on your machine ...
