Parámetros

Descripción

Draw a rectangle handle. Pass this into handle functions.

On EventType.Layout event, calculates handle distance to mouse and calls HandleUtility.AddControl accordingly.

On EventType.Repaint event, draws the handle shape.

Rectangle Handle Cap in the Scene View.

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

using UnityEngine;

public class RectangleExample : MonoBehaviour {}

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

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(RectangleExample))]
public class RectangleExampleEditor : Editor
{
    float size = 1f;

    protected virtual void OnSceneGUI()
    {
        if (Event.current.type == EventType.Repaint)
        {
            Transform transform = ((RectangleExample)target).transform;
            Handles.color = Handles.xAxisColor;
            Handles.RectangleHandleCap(
                0,
                transform.position + new Vector3(3f, 0f, 0f),
                transform.rotation * Quaternion.LookRotation(Vector3.right),
                size,
                EventType.Repaint
                );
            Handles.color = Handles.yAxisColor;
            Handles.RectangleHandleCap(
                0,
                transform.position + new Vector3(0f, 3f, 0f),
                transform.rotation * Quaternion.LookRotation(Vector3.up),
                size,
                EventType.Repaint
                );
            Handles.color = Handles.zAxisColor;
            Handles.RectangleHandleCap(
                0,
                transform.position + new Vector3(0f, 0f, 3f),
                transform.rotation * Quaternion.LookRotation(Vector3.forward),
                size,
                EventType.Repaint
                );
        }
    }
