鼠标事件

        //鼠标事件this.node.on(cc.Node.EventType.MOUSE_DOWN, (e: cc.Event.EventMouse) => {cc.log(e.getLocation() + "")if (e.getButton() == cc.Event.EventMouse.BUTTON_LEFT) {cc.log("鼠标左键")}})

键盘事件

//键盘事件cc.systemEvent.on(cc.SystemEvent.EventType.KEY_DOWN, (e: cc.Event.EventKeyboard) => {cc.log(e.keyCode + "")if (e.keyCode == cc.macro.KEY.a) {cc.log("点击a")}})

触摸事件

        //触摸事件this.node.on(cc.Node.EventType.TOUCH_START, (e: cc.Event.EventTouch) => {cc.log("触摸" + e.getLocation())})

自定义事件（消息通知）

• 发送通知（2种方式）

this.node.on(cc.Node.EventType.MOUSE_DOWN, () => {cc.log("点击按钮，发送事件1")cc.find("human").emit("msg")})

this.node.on(cc.Node.EventType.MOUSE_DOWN, () => {cc.log("点击按钮，发送事件2")let event = new cc.Event.EventCustom("msg", true)event.detail = {date: new Date(), text: "hello"}cc.find("human").dispatchEvent(event)})

• 接收方

        //自定义事件，例如通知this.node.on("msg", (e:cc.Event.EventCustom) => {cc.log("自定义事件触发")cc.log(e.detail.text)})
