@Sataniel That is great, and I can get that from GlowServer, but the thing is; required methods, such as EntityManager#register are package private. That means that unless I am in that package (Which I will never be, unless I help make a commit or something) I cannot use those methods. And @gdude2002 I am going to make a pull request to make those methods public. Once that happens, I will be able to make the custom entities. UPDATE: I have now made the pull request: here.
