Parallax

1. 创建地图

 this._tilemap = cc.TMXTiledMap.create(s_resprefix + "TileMaps/orthogonal-test2.tmx");

2. 创建视差结点

 this._parentNode = cc.ParallaxNode.create();

        // NOW add the 3 layers to the 'void' node

        // background image is moved at a ratio of 0.4x, 0.5y
        this._parentNode.addChild(this._background, -1, cc.p(0.4, 0.5), cc.p(0,0));

        // tiles are moved at a ratio of 2.2x, 1.0y
        this._parentNode.addChild(this._tilemap, 1, cc.p(2.2, 1.0), cc.p(0, 0));

        // top image is moved at a ratio of 3.0x, 2.5y
        this._parentNode.addChild(this._cocosimage, 2, cc.p(3.0, 2.5), cc.p(0, 0));

3.移动

if( 'touches' in cc.sys.capabilities ){
            cc.eventManager.addListener({
                event: cc.EventListener.TOUCH_ALL_AT_ONCE,
                onTouchesMoved:function (touches, event) {
                    var touch = touches[0];
                    var node = event.getCurrentTarget().getChildByTag(TAG_NODE);
                    node.x += touch.getDelta().x;
                    node.y += touch.getDelta().y;
                }
            }, this);
        } else if ('mouse' in cc.sys.capabilities ){
            cc.eventManager.addListener({
                event: cc.EventListener.MOUSE,
                onMouseMove: function(event){
                    var node = event.getCurrentTarget().getChildByTag(TAG_NODE);
                    node.x += event.getDeltaX();
                    node.y += event.getDeltaY();
                }
            }, this);
        }
