How to mouse click an object in scene view to select it from editor

Question

I have several game objects with colliders in my game. I have enabled Always Show Colliders to keep all of them visible in my scene view. Because the objects are a lot, selecting them from the hierarchy window is a bit cumbersome and really slowing down my workflow. How can I select an object by left mouse clicking on it in the scene view of an editor?

Answer 1

If you want to be able to select colliders without adding any sort of mesh to them, then you can call an icon draw OnDrawGizmos() on a script and just add it to whatever you want to be drawn:

using System.Collections;

using System.Collections.Generic;
using UnityEngine;

public class DrawIcon : MonoBehaviour {
    void OnDrawGizmos()
    {
        Gizmos.DrawIcon(transform.position, "Collider Gizmo.tiff", true);
    }
}

You can also then select a shape / color combo from the gizmos menu for DrawIcon in this case.

Clicking on it will select the relevant object:

Experiment with the code to customize it.
