[SOLVED] [1.11.2] Problem during server start

[MennoMax]

Whenever I try to start the server (client works fine), it crashes during the preInit phase of my mod. First, I thought I might've messed the proxies up, but nothing client-sided should be called server-side there. I have no idea why net/minecraft/client/renderer/entity/Render is being loaded serverside.

ServerProxy.class only contains empty methods implemented from the CommonProxy interface.

 

Basically, this mod currently only adds a flyable broom to the game that is steerable and locked to the players UUID once placed (so nobody else can ride it). If you need any other classes just tell me, I appreciate any help of you I can get. It's probably just some small thing causing this error and I just can't find it.

 

I am currently using forge 1.11.2-13.20.0.2262, but already tried using the latest build. (same error there)

edit: nevermind, didn't look close enough

Edited May 30, 2017 by Ugdhar

[MennoMax]

It's already included (PotterMod.class)

[Choonster]

Post the EntityTestbroom class, the issue may be there.

 

It's best to keep client-only code like model registration in dedicated client-only classes to help avoid issues like this, though PotterEntities.registerRenders probably isn't the cause of the issue.

 

Side note: RenderingRegistry#registerEntityRenderingHandler(Class<? Entity>, Render<? extends Entity>) is deprecated, call RenderingRegistry#registerEntityRenderingHandler(Class<T>, IRenderFactory<? super T>) in preInit instead.

[MennoMax]

Thank you very much, your side note actually fixed it already. I knew it was something small.
