Unity Inspector添加自定义按钮(Button)

效果拔群

         在Unity开发游戏的时候，为了有一个更快更方便的工作流，我们往往会在Editor下开发一些方便实用的工具。在工具中，用到最多，最关键的就是按钮，它是工具的首席执行官。下面就用最简单的代码来演示添加一个自定义按钮到Inspector当中。

         案例：指定坐标后克隆新物体到场景。

1、  在Unity Assets下创建”ObjectBuilderScript”脚本，添加代码：

1. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">using UnityEngine;<o:p></o:p></span></strong></p>
   
2. 
   
3. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"=""> </span></strong></p>
   
4. 
   
5. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">public class ObjectBuilderScript
   
6. : MonoBehaviour {<o:p></o:p></span></strong></p>
   
7. 
   
8. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">    public GameObject obj;<o:p></o:p></span></strong></p>
   
9. 
   
10. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">    public Vector3 spawnPoint;<o:p></o:p></span></strong></p>
    
11. 
    
12. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"=""> </span></strong></p>
    
13. 
    
14. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">    public void BuildObject() {<o:p></o:p></span></strong></p>
    
15. 
    
16. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">        Instantiate(obj, spawnPoint,
    
17. Quaternion.identity);<o:p></o:p></span></strong></p>
    
18. 
    
19. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">    }<o:p></o:p></span></strong></p>
    
20. 
    
21. <p class="MsoNormal" style="margin-left:39.0pt"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">}</span></strong></p>

复制代码

2、  在Unity Assets下创建”Editor”文件夹，文件夹下创建”ObjectBuilderEditor”脚本，添加代码：

1. <p class="MsoListParagraph" style="margin-left:39.0pt;text-indent:0cm;mso-char-indent-count:
   
2. 0"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">using UnityEngine;<o:p></o:p></span></strong></p>
   
3. 
   
4. <p class="MsoListParagraph" style="margin-left:39.0pt;text-indent:0cm;mso-char-indent-count:
   
5. 0"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"="">using UnityEditor;<o:p></o:p></span></strong></p>
   
6. 
   
7. <p class="MsoListParagraph" style="margin-left:39.0pt;text-indent:0cm;mso-char-indent-count:
   
8. 0"><strong><span lang="EN-US" calibri",sans-serif;mso-ascii-theme-font:minor-latin;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" new="" roman";="" mso-bidi-theme-font:minor-bidi;font-weight:normal"=""> </span></strong></p>

3、  场景中添加一个空的GameObject对象，挂载上” ObjectBuilderScript”脚本，在Inspector中选中需要克隆的游戏对象，填入克隆对象的出生点坐标，点击“创建对象”按钮，就将克隆对象添加到场景当中。如图：
