<as> // Z-order example

1. include "ball.as"

balls = 5; zbuff = []; angle = 0; arc = 2 * Math.PI / balls;

// Create some balls each of different colours and put in z-buffer for ( i = 0; i < balls; i++ ) { j = i + 1; colour = (j & 1) ? 0xff0000 : 0; colour |= (j & 2) ? 0x00ff00 : 0; colour |= (j & 4) ? 0x0000ff : 0; zbuff[i] = createSymbol( this, 'ball', 'ball' + i, i, colour ); }

// Per frame function reduce() {

// Sort the z-buffer by z zbuff.sort( function(a,b) { return a.z > b.z; } );

// Set ball coordinates, scales and depths for this frame angle += 0.05; for ( i = 0; i < balls; i++ ) { obj = _root['ball'+i]; b = angle + arc * i; obj.z = obj._xscale = obj._yscale = 50 + Math.cos(b) * 10; obj._x = width / 2 + Math.sin(b) * width / 3; obj._y = obj.z * 2; zbuff[i].swapDepths(i); }
