TextMeshPro 使用
TMP在Unity2018中是带有动态字体这个功能的 在Unity2018之前的版本中 都是以package的形式导入的并且不支持动态字体
方式方法
1.生成一个7000+的静态字体上挂载一个动态字体资产 通常来说7000+够用了 但是异体字生僻字繁体字不全 会导致文本渲染不出的问题
2.自己写个工具把项目中用到的中文收集起来去生成一个静态字体资产然后挂载一个动态字体 这样做的好处是静态字体可控 占用的内存相对较少
3.纯动态字体 使用动态图集的多图集模式
静态字体的生成
一个需要生成的字体文件
点击生成保存即可
动态字体资源的创建
右键选中字体文件
会创建出一个xxx.asset
是一个ScriptableObject 的序列化资产, 根据自己项目的资源管理打包加载
静态字体增加动态字体的依赖
运行时在文本渲染时如果静态字体找不到会把文字动态生成到动态图集中
反射对TMP_Settings.Instance赋值
TMP的代码是通过Resources.Load加载TMPSettings.asset的 如果你不想这么实现 魔改代码根据自己的资源管理加载也可以
嫌麻烦的游戏开始时反射赋值也可以
TMP_Settings tMP_Settings = Assetbundle.LoadAllAssets<TMP_Settings>()[0];
Type type = typeof(TMP_Settings);
FieldInfo fieldInfo = type.GetField("s_Instance", BindingFlags.Static | BindingFlags.NonPublic);
fieldInfo.SetValue(null, tMP_Settings);
反射调用底层方法
如果想删除TextMeshPro.asmdef的可能会用得到
