Parámetros

Descripción

Draw a dot 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.

Dot Handle Cap in the Scene View.

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

using UnityEngine;

public class DotExample : MonoBehaviour {}

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

using UnityEditor;
using UnityEngine;

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

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