Unity5 C＃：如何通过触摸拖动旋转GameObject

Question

I have a cube in my scene which I want to to rotate as player touch and drag it. here is the code

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
Physics.Raycast (ray, out hit);

if(Input.GetMouseButton(0) &&  hit.collider.name == "Cube")
{
    xDeg -= Input.GetAxis("Mouse X") * speed * friction;
    yDeg += Input.GetAxis("Mouse Y") * speed * friction;
    fromRotation = cube.transform.rotation;
    toRotation = Quaternion.Euler(yDeg,xDeg,0);
    cube.transform.rotation = Quaternion.Lerp(fromRotation,toRotation,Time.deltaTime  * lerpSpeed);
}

I am 100% able to do that, problem is I have placed several other game objects with colliders on each wall of cube. All I want is player to be able to rotate cube around and perform some action by tapping on specific game objects on each wall. here is the rest of code

if (Input.GetMouseButtonUp(0))
{
    Ray ray1 = Camera.main.ScreenPointToRay(Input.mousePosition);
    if (Physics.Raycast (ray1, out hit)) {
        if (hit.collider.name == "ABC") {
            //Perform action specific to ABC
        }   
     }
 }

Now if I try rotating the cube it runs ABC (because definitely rayCast work it suppose to be). I can't figure out how I actually achieve this that player became able to rotate the cube by touch and drag as well as perform some action by just tapping on walls of same cube.

Answer 1

Put your cube collider in a different layer than the other objects. Then call the version of Physics.Raycast that takes a layerMask.
