进阶双开门事件绑定同时触发"/>

【Babylon小技巧04】进阶双开门事件绑定同时触发

鼠标点击其中一扇门时，另外一扇也同时开启或关闭

效果如图

双开门playground地址：

Babylon.js Playground

主要思路为使用combineAction绑定了多个模型的鼠标事件，顺便多绑定一个箱子做放大缩小测试

let combineOpenDoorAction  = new BABYLON.CombineAction(BABYLON.ActionManager.OnPickTrigger,[new BABYLON.InterpolateValueAction(BABYLON.ActionManager.OnPickTrigger, _leftDoorMesh, "rotation.y",-Math.PI/2 , 1500),new BABYLON.InterpolateValueAction(BABYLON.ActionManager.OnPickTrigger, _rightDoorMesh, "rotation.y",Math.PI/2 , 1500),new BABYLON.ExecuteCodeAction(BABYLON.ActionManager.OnPickTrigger, function (e) {// alert(e.source.id +"combineOpenDoorAction");_triggerMesh.scaling = new BABYLON.Vector3(1.5,1.5,1.5);_triggerMesh.position.y = 2;})]);
