Handles.ScaleHandle

参数

返回

Vector3 通过用户与手柄的交互修改的新值。如果用户没有移动手柄，则将返回您传递给相应函数的值。

描述

创建一个场景视图缩放手柄。

注意：如果您希望拥有恒定屏幕大小的手柄，请使用 HandleUtility.GetHandleSize。

此手柄的行为类似于内置缩放工具


Scale handle that will appear whenever you select the GameObject.

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

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

        EditorGUI.BeginChangeCheck();
        Vector3 scale = Handles.ScaleHandle(t.scale, Vector3.zero, Quaternion.identity, 1);
        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(target, "Scaled ScaleAt Point");
            t.scale = scale;
            t.Update();
        }
    }
}

附加到此游戏对象的脚本：

// Name this script "ScaleAtPoint"
using UnityEngine;
[ExecuteInEditMode]
public class ScaleAtPoint : MonoBehaviour
{
    public Vector3 scale = Vector3.one;
    public void Update()
    {
        transform.localScale = scale;
    }
}
