Descripción

Make an unconstrained movement handle.

This can move freely in all directions. Hold down CMD to snap, CMD-SHIFT to raysnap against colliders in the Scene.


Free Move handle in the Scene View.

Note: Use HandleUtility.GetHandleSize if you want the handle to always remain the same size on the screen.

// Name this script "FreeMoveEditor"
using UnityEngine;
using UnityEditor;

[CustomEditor(typeof(FreeMove))]
[CanEditMultipleObjects]
public class FreeMoveEditor : Editor
{
    public void OnSceneGUI()
    {
        FreeMove t = (target as FreeMove);

        EditorGUI.BeginChangeCheck();
        Vector3 pos = Handles.FreeMoveHandle(t.lookAtPoint, Quaternion.identity, .5f, new Vector3(.5f, .5f, .5f), Handles.RectangleCap);
        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(target, "Free Move LookAt Point");
            t.lookAtPoint = pos;
            t.Update();
        }
    }
}

And the script attached to this handle:

// Name this script "FreeMove"
using UnityEngine;

[ExecuteInEditMode]
public class FreeMove : MonoBehaviour
{
    public Vector3 lookAtPoint = Vector3.zero;

    public void Update()
    {
        transform.LookAt(lookAtPoint);
    }
}
