Description

Make a 3D Button.

This button works like one drawn with GUI.Button, but it has a 3D position and is drawn by a handle function.


Button Handle as a rectangle in the Scene View.

Add the following script to your Assets folder as ButtonExample.cs and add the ButtonExample component to an object in a Scene.

using UnityEngine;

public class ButtonExample : MonoBehaviour {}

Add the following script to Assets/Editor as ButtonExampleEditor.cs and select the object with the ButtonExample component.

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(ButtonExample)), CanEditMultipleObjects] class ButtonExampleEditor : Editor { protected virtual void OnSceneGUI() { ButtonExample buttonExample = (ButtonExample)target;

Vector3 position = buttonExample.transform.position + Vector3.up * 2f; float size = 2f; float pickSize = size * 2f;

if (Handles.Button(position, Quaternion.identity, size, pickSize, Handles.RectangleHandleCap)) Debug.Log("The button was pressed!"); } }
