Collider inside another collider : I have these spheres inside the brain, and I want to be able to move the brain via mouse while being able the click the spheres

Question

alt text The spheres have a sphere collider on them and are clickable via this script:`Clickable.cs` public class Clickable : MonoBehaviour { void Update() { ClickDetect();

 }
 void ClickDetect()
 {

     RaycastHit hit;
     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);



     if (Physics.Raycast(ray, out hit))
     {
         Transform t = hit.collider.transform;
       
         if (t.name == "Sphere(Clone)")
         {


          
             if (Input.GetMouseButtonDown(0))
             {
                 
                     hit.collider.gameObject.GetComponent<Light>().color = new Color(1, 0, 0, 0.7f);

                 Debug.Log(t.parent.name + (t.GetSiblingIndex() + 1));
             }



         }
     }
 }}

and the brain has a box collider on it and is moved by this script RotateonMouse
`void Rotation() { if (_isRotating) { // offset _mouseOffset = (Input.mousePosition - _mouseReference);

         // apply rotation
         _rotation.y = -(_mouseOffset.x) * _sensitivity;
         _rotation.x = -(_mouseOffset.y) * _sensitivity;

         // rotate
         transform.eulerAngles += _rotation;

         // store mouse
         _mouseReference = Input.mousePosition;
     }

 }

The issue arises when I try to click on the spheres when the box collider on the brain is on. I end up rotating the brain instead of being able to click the spheres. Is there a way to be able to click inside the collider while also on the collider to rotate the brain?.

A way to solve this is to handle both of these behaviors in a single script so you can more easily give precedence to one of them. Otherwise you'd need a third script that oversees both of them to achieve this.

So, my suggestion is to move the code from the Rotation method inside RotateOnMouse to the ClickDetect method (and rename it if you deem it appropriate). After you do that make sure that the Rotation code will execute if and only if you failed to hit a sphere with the raycast. This way, only 1 of the 2 actions can happen at once, and the sphere clicking will have precedence.

@AltaNox So I tried what you had suggested, but I have to move inside the box collider of the brain to click the spheres, the brain collider is intercepting all the clicks. The spheres are children of the brain and are effectively covered by its collider. Is there something I'm missing? Thanks for your help

Hello @ASE-Lab! I know this topic is from quite a while but I've run into this exact problem and was wondering if you've managed to solve it and how? Thx!
