Unity TextMeshPro源码修改

为了拓展TextMeshPro的功能，写一些TextMeshPro的工具，打算把TextMeshPro直接导到项目内，好修改源码。
其实只要把Libray文件夹下的TextMeshPro拷贝一份到项目内，然后在PackageManager里移除TextMeshPro包就好了。


但是，这个时候我们会发现一些图标没了。

其实是路径的问题，没加载到Editor Resources，修改部分源码即可。

修改如下：

		//TMP_EditorUtility.cs
		private static string GetPackageRelativePath()
        {
    
    
        	//这里直接return就好了
            return "Assets/Plugins/TextMeshPro";
            // Check for potential UPM package
            // ...
            }

            return null;
        }

原因可以看这里：

		//TMP_UIStyleManager.cs
        static TMP_UIStyleManager()
        {
    
    
            // Find to location of the TextMesh Pro Asset Folder (as users may have moved it)
            var tmproAssetFolderPath = TMP_EditorUtility.packageRelativePath;

            if (EditorGUIUtility.isProSkin)
            {
    
    
                alignLeft = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignLeft.psd", typeof(Texture2D)) as Texture2D;
                alignCenter = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignCenter.psd", typeof(Texture2D)) as Texture2D;
                alignRight = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignRight.psd", typeof(Texture2D)) as Texture2D;
                alignJustified = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignJustified.psd", typeof(Texture2D)) as Texture2D;
                alignFlush = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignFlush.psd", typeof(Texture2D)) as Texture2D;
                alignGeoCenter = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignCenterGeo.psd", typeof(Texture2D)) as Texture2D;
                alignTop = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignTop.psd", typeof(Texture2D)) as Texture2D;
                alignMiddle = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignMiddle.psd", typeof(Texture2D)) as Texture2D;
                alignBottom = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignBottom.psd", typeof(Texture2D)) as Texture2D;
                alignBaseline = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignBaseLine.psd", typeof(Texture2D)) as Texture2D;
                alignMidline = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignMidLine.psd", typeof(Texture2D)) as Texture2D;
                alignCapline = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/btn_AlignCapLine.psd", typeof(Texture2D)) as Texture2D;
                sectionHeaderTexture = AssetDatabase.LoadAssetAtPath(tmproAssetFolderPath + "/Editor Resources/Textures/SectionHeader_Dark.psd", typeof(Texture2D)) as Texture2D;
            }
            else
            {
    
    
            .......
        }
