大家好，我是佛系工程师☆恬静的小魔龙☆，不定时更新Unity开发技巧，觉得有用记得一键三连哦。
一、前言
在开发中，常常会遇到频繁复制粘贴物体的坐标、旋转、缩放的操作。
使用Unity自带的组件复制粘贴比较麻烦：
复制：
粘贴：
还有一些需要复制位置、旋转、缩放的值到到代码中，如果一个一个复制粘贴非常麻烦，还要一些需要复制添加自定义文本，也很不方便。
所以，就开发了一个小工具，来提升开发效率。
二、正文
2-1、实现快速复制/粘贴，位置/旋转/缩放功能
效果图：
在Editor文件夹中新建脚本，随便命名，然后编辑代码：
using UnityEngine;
using UnityEditor;
using System.Text;
using static UnityEditor.IMGUI.Controls.PrimitiveBoundsHandle;
using static UnityEngine.UI.Image;
[CanEditMultipleObjects]
[CustomEditor(typeof(Transform), true)]
public class TransformEditor : Editor
{
static public TransformEditor instance;
//当前的本地坐标
SerializedProperty mPos;
//当前的本地旋转
SerializedProperty mRot;
//当前的本地缩放
SerializedProperty mScale;
void OnEnable()
{
instance = this;
if (this)
{
try
{
var so = serializedObject;
mPos = so.FindProperty("m_LocalPosition");
mRot = so.FindProperty("m_LocalRotation");
mScale = so.FindProperty("m_LocalScale");
}
catch { }
}
}
void OnDestroy() { instance = null; }
/// 运行结果：
这样就实现了基本的快速复制/粘贴，位置/旋转/缩放功能。
接下来，就实现单独的位置、旋转、缩放的复制和粘贴吧。
2-2、单独的位置、旋转、缩放的赋值粘贴功能
效果图：
示例代码：
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using UnityEditor;
using UnityEngine;
public class ButtonHandler
{
public string showDescription;
public Action onClickCallBack;
public ButtonHandler(string showDescription, Action onClickCallBack)
{
this.showDescription = showDescription;
this.onClickCallBack = onClickCallBack;
}
}
[CanEditMultipleObjects]
[CustomEditor(typeof(Transform))]
public class TransformEditor2 : Editor
{
static public Editor instance;
private bool extensionBool;
ButtonHandler[] buttonHandlerArray;
//当前的本地坐标
SerializedProperty mPos;
//当前的本地旋转
SerializedProperty mRot;
//当前的本地缩放
SerializedProperty mScale;
private void OnEnable()
{
instance = this;
var editorType = Assembly.GetAssembly(typeof(Editor)).GetTypes().FirstOrDefault(m => m.Name == "TransformInspector");
instance = CreateEditor(targets, editorType);
if (this)
{
try
{
var so = serializedObject;
mPos = so.FindProperty("m_LocalPosition");
mRot = so.FindProperty("m_LocalRotation");
mScale = so.FindProperty("m_LocalScale");
}
catch { }
}
extensionBool = EditorPrefs.GetBool("extensionBool");
buttonHandlerArray = new ButtonHandler[9];
buttonHandlerArray[0] = new ButtonHandler("Position Copy", () =>
{
var select = Selection.activeGameObject;
if (select == null)
return;
StringBuilder s = new StringBuilder();
// x,y,z
s.Append(mPos.vector3Value.x.ToString() + "," + mPos.vector3Value.y.ToString() + "," + mPos.vector3Value.z.ToString());
//添加到剪贴板
UnityEngine.GUIUtility.systemCopyBuffer = s.ToString();
});
buttonHandlerArray[1] = new ButtonHandler("Position Paste", () =>
{
//把数值打印出来
string s = UnityEngine.GUIUtility.systemCopyBuffer;
try
{
mPos.vector3Value = ParseV3(s);
}
catch (System.Exception ex)
{
Debug.LogError(ex);
return;
}
});
buttonHandlerArray[2] = new ButtonHandler("Position Reset", () =>
{
mPos.vector3Value = Vector3.zero;
});
buttonHandlerArray[3] = new ButtonHandler("Rotation Copy", () =>
{
//把数值打印出来
var select = Selection.activeGameObject;
if (select == null)
return;
StringBuilder s = new StringBuilder();
s.Append(mRot.quaternionValue.eulerAngles.x + "," + mRot.quaternionValue.eulerAngles.y + "," + mRot.quaternionValue.eulerAngles.z);
//添加到剪贴板
UnityEngine.GUIUtility.systemCopyBuffer = s.ToString();
});
buttonHandlerArray[4] = new ButtonHandler("Rotation Paste", () =>
{
//把数值打印出来
Debug.Log(UnityEngine.GUIUtility.systemCopyBuffer);
string s = UnityEngine.GUIUtility.systemCopyBuffer;
try
{
mRot.quaternionValue = Quaternion.Euler(ParseV3(s));
}
catch (System.Exception ex)
{
Debug.LogError(ex);
return;
}
});
buttonHandlerArray[5] = new ButtonHandler("Rotation Reset", () =>
{
mRot.quaternionValue = Quaternion.identity;
});
buttonHandlerArray[6] = new ButtonHandler("Scale Copy", () =>
{
//把数值打印出来
var select = Selection.activeGameObject;
if (select == null)
return;
StringBuilder s = new StringBuilder();
s.Append(mScale.vector3Value.x.ToString() + "," + mScale.vector3Value.y.ToString() + "," + mScale.vector3Value.z.ToString());
//添加到剪贴板
UnityEngine.GUIUtility.systemCopyBuffer = s.ToString();
});
buttonHandlerArray[7] = new ButtonHandler("Scale Paste", () =>
{
//把数值打印出来
Debug.Log(UnityEngine.GUIUtility.systemCopyBuffer);
string s = UnityEngine.GUIUtility.systemCopyBuffer;
try
{
mScale.vector3Value = ParseV3(s);
}
catch (System.Exception ex)
{
Debug.LogError(ex);
return;
}
});
buttonHandlerArray[8] = new ButtonHandler("Scale Reset", () =>
{
mScale.vector3Value = Vector3.one;
});
}
private void OnDisable()
{
EditorPrefs.SetBool("extensionBool", extensionBool);
}
public override void OnInspectorGUI()
{
instance.OnInspectorGUI();
GUI.color = Color.cyan;
extensionBool = EditorGUILayout.Foldout(extensionBool, "拓展功能");
if (extensionBool)
{
EditorGUILayout.BeginHorizontal();
for (int i = 0; i < buttonHandlerArray.Length; i++)
{
ButtonHandler temporaryButtonHandler = buttonHandlerArray[i];
if (GUILayout.Button(temporaryButtonHandler.showDescription, "toolbarbutton"))//, GUILayout.MaxWidth(150)
{
temporaryButtonHandler.onClickCallBack();
}
GUILayout.Space(5);
if ((i + 1) % 3 == 0 || i + 1 == buttonHandlerArray.Length)
{
EditorGUILayout.EndHorizontal();
if (i + 1 < buttonHandlerArray.Length)
{
GUILayout.Space(5);
EditorGUILayout.BeginHorizontal();
}
}
}
}
GUI.color = Color.white;
serializedObject.ApplyModifiedProperties();
}
Vector3 ParseV3(string strVector3)
{
string[] s = strVector3.Split(',');
return new Vector3(float.Parse(s[0]), float.Parse(s[1]), float.Parse(s[2]));
}
}
演示：
这样就实现了单独的位置/旋转/缩放复制/粘贴功能。
接下来，就实现单独的位置/旋转/缩放复制/粘贴功能以及位置/旋转/缩放一起复制和粘贴功能。
以及，自定义文本拼接的功能。
2-3、自定义文本拼接的功能
