Font

UE 支持两种字体类型，offline和runtime cached
只有runtime才被UMG支持

Note

• A new cache entry is needed Whenever you use a different

font font size. outline size or character

• Unreal Engine supports Unicode, providing font rendering for

any language

• Keep in mind your true type font needs to include the requested

characters. otherwise a fallback font （备用字体）will be used

Practice

建议在程序一开始就把所有cache渲染好，避免渲染卡顿，造成晕动症

Widget

• have smooth follow behavior
• Change the interpolation speed
• Change the attach point

Widget 之间的嵌套，构成了层级，Hierarchy
