enchant.jsでドラッグ＆ドロップ

javascript

TOUCH_STARTイベント時にドラッグ開始位置を記憶して、
TOUCH_MOVEイベントで随時座標を変化させる感じ。

		var bear = new Sprite(32, 32);
		bear.image = game.assets['chara1.gif'];
		bear.x = 100;
		bear.y = 200;
		
		bear.addEventListener(enchant.Event.TOUCH_START, function(e){
			originX = e.x - this.x;
			originY = e.y - this.y;
		});
		bear.addEventListener(enchant.Event.TOUCH_MOVE, function(e){
			this.x = e.x - originX;
			this.y = e.y - originY;
		});
