cocoscreator有没有屏幕的重力感应事件？
cc.Class({
extends: cc.Component,
onLoad () {
// open Accelerometer
cc.systemEvent.setAccelerometerEnabled(true);
cc.systemEvent.on(cc.SystemEvent.EventType.DEVICEMOTION, this.onDeviceMotionEvent, this);
},
onDestroy () {
cc.systemEvent.off(cc.SystemEvent.EventType.DEVICEMOTION, this.onDeviceMotionEvent, this);
},
onDeviceMotionEvent (event) {
cc.log(event.acc.x + " " + event.acc.y);
},
});
官方给的给的api使用怎么没效果？？
