x and y Coordinates in 1D Array / Vector

By Zevan | June 14, 2009

CLICK HERE TO COPY
Actionscript:

var canvas:BitmapData=new BitmapData(400,400,false,0x000000);

addChild(new Bitmap(canvas));

var pix:Vector.<uint>=canvas.getVector(canvas.rect);

 

canvas.lock();

for (var i:int = 0; i<300; i++) {

    var xp:int=50+i;

    var yp:int=50+i/2;

    // target x and y coords in 1D array

    pix[xp+yp*400]=0xFFFFFF;

}

canvas.setVector(canvas.rect, pix);

canvas.unlock();

This snippet shows how to target x and y coordinates in a 1D Array / Vector. This can be useful sometimes when [...]
