Key Files for Modding

File	Description
HytaleServer.jar	Java server - decompile this for API investigation
Assets.zip	Game assets (models, textures, prefabs)
UserData/Mods/	Where mods are installed

Notes

• Client: Native C++ executable (not directly moddable via Java)

• Server: Java-based, supports plugin/mod development

• Modding: Plugins interact with the server JAR API
