Simple lines
This is just something I hastily threw together this morning (damnit boredom!). Here’s the source code in its entirety.
const MaxRays: int = 50,
MaxVelocity: Number = 1,
Resolution: Point = new Point(550, 400);
var rays: Array = new Array(),
sceneBMD: BitmapData = new BitmapData(Resolution.x, Resolution.y, false, 0),
canvasSprite:Sprite = new Sprite(),
timer: Timer=new Timer(20);
this.addChild(new Bitmap(sceneBMD));
timer.addEventListener(TimerEvent.TIMER, UpdateRays);
CreateRays();
timer.start();
function CreateRays() {
while (rays.length < MaxRays) {
var newRay: Object = new Object();
newRay.point1 = new Point(Math.random() * Resolution.x, Math.random() * Resolution.y);
newRay.point2 = new Point(Math.random() * Resolution.x, Math.random() * Resolution.y);
newRay.velocity1 = new Point(-MaxVelocity + 2 * Math.random() * MaxVelocity,0);
newRay.velocity1.y = (MaxVelocity – Math.abs(newRay.velocity1.x)) + (MaxVelocity – Math.abs(newRay.velocity1.x)) * -2 * int(Math.random() < 0.5);
newRay.velocity2 = new Point(-MaxVelocity + 2 * Math.random() * MaxVelocity,0);
newRay.velocity2.y = (MaxVelocity – Math.abs(newRay.velocity2.x)) + (MaxVelocity – Math.abs(newRay.velocity2.x)) * -2 * int(Math.random() < 0.5);
newRay.color = Math.floor(Math.random() * 256) * 256 * 256 + Math.floor(Math.random() * 256) * 256 + Math.floor(Math.random() * 256);
rays.push(newRay);
}
}
function UpdateRays(evt: TimerEvent) {
sceneBMD.colorTransform(sceneBMD.rect, new ColorTransform(1, 1, 1, 0.995));
for (var i: int = 0; i < rays.length; i++) with (rays[i]) {
point1.x += velocity1.x; point1.y += velocity1.y;
point2.x += velocity2.x; point2.y += velocity2.y;
velocity1.x = velocity1.x – 2 * velocity1.x * int(point1.x < 0 && velocity1.x Resolution.x && velocity1.x > 0);
velocity1.y = velocity1.y – 2 * velocity1.y * int(point1.y < 0 && velocity1.y Resolution.y && velocity1.y > 0);
velocity2.x = velocity2.x – 2 * velocity2.x * int(point2.x < 0 && velocity2.x Resolution.x && velocity2.x > 0);
velocity2.y = velocity2.y – 2 * velocity2.y * int(point2.y < 0 && velocity2.y Resolution.y && velocity2.y > 0);
canvasSprite.graphics.lineStyle(1, color, 0.1);
canvasSprite.graphics.moveTo(point1.x, point1.y);
canvasSprite.graphics.lineTo(point2.x, point2.y);
}
sceneBMD.draw(canvasSprite);
canvasSprite.graphics.clear();
}
