3D for lazy dummies (AS3)

3D is fun, but 3D is hard to learn! So let’s keep it simple today and play with a simple 3D illusion with layers and Action Script.

As usual, code source is available here.

And below is the code:

Enjoy!

import caurina.transitions.*

var timeTrans:Number = 0.6; 
var margin:int= 15; 
var keepIt:Boolean = false;
var swfWidth:Number = stage.stageWidth;

left_btn.addEventListener(MouseEvent.CLICK, leftSlide);
left_btn.addEventListener(MouseEvent.ROLL_OVER, leftSlide);
left_btn.addEventListener(MouseEvent.ROLL_OUT, keepItFalse);
	
right_btn.addEventListener(MouseEvent.CLICK, rightSlide);
right_btn.addEventListener(MouseEvent.ROLL_OVER, rightSlide);
right_btn.addEventListener(MouseEvent.ROLL_OUT, keepItFalse);
	
function keepItFalse(e:MouseEvent){
	keepIt = false;
}

// Move in the right direction
function leftSlide(e:MouseEvent = null) {
	 if(back_mc.x < -margin){
		 keepIt = true;
		 keepLeft();
	 }
}
function keepLeft(){
	if(back_mc.x < -margin){
		if(keepIt == true){
			Tweener.addTween(back_mc, {x:(back_mc.x + margin), time:timeTrans, transition:"linear"});
			Tweener.addTween(middle_mc, {x:(middle_mc.x + margin*2), time:timeTrans, transition:"linear", onComplete:keepLeft});
			Tweener.addTween(front_mc, {x:(front_mc.x + margin*4), time:timeTrans, transition:"linear"});
		}
	}
}

// Move thowards the left side
function rightSlide(e:MouseEvent = null) {
	if(-back_mc.x < back_mc.width - swfWidth-margin ){
		keepIt = true;
		keepRight();
	}
}
function keepRight(){
	if(-back_mc.x < back_mc.width - swfWidth-margin ){
		if(keepIt == true){
			Tweener.addTween(back_mc, {x:(back_mc.x - margin), time:timeTrans, transition:"linear" });
			Tweener.addTween(middle_mc, {x:(middle_mc.x - margin*2), time:timeTrans, transition:"linear", onComplete:keepRight});
			Tweener.addTween(front_mc, {x:(front_mc.x - margin*4), time:timeTrans, transition:"linear"});
		}
	}
}
