【游戏-unity】Unity TextMeshPro 字库的自动生成

TextMeshProDemo.cs

//在Unity中使用TextMeshPro的文本解决方案，当要生成字库图集时，需要通过插件提供的 【Font Asset Creator】工具，但是每次都需要重新设置选项。
//反编译编辑器查看其代码，照着其实现步骤再实现一遍，注意的是升级插件的话，也要看下实现的代码是否需要改动。另外，自动处理多个字体的部分逻辑如下：

        m_FontAssetInfos[m_CurGenerateIndex].genPercent = progress * 100;
        this.Repaint();
    }
    if (!this.isRenderingDone)
    {
        return;
    }
