(TX's own Orc recognition pictures don't need you to waste a lot of energy on font library. If you encounter an update or unrecognized image, open the debugging mode, double-click the unrecognized image, and the feature library will be updated automatically. Cloud top update: if you add or delete heroes, initialize the cloud top class in the code and add or modify heroes according to the format (you can expand them into external configuration files without moving the code))
