How do I make a single-player mod able to run on a server?

[Will Bradley]

Specifically, what do I need to do to make my code which works on single-player run on a server? I'm familiar with sidedness, I'm just lost on what boilerplate code/pitfalls I should be aware of.

 

Thanks!

It works great in single player! But don't some operations like Minecraft.getInstance() crash servers, even though they work fine on single player worlds?

[Will Bradley]

According to the docs, EventBusSubscriber only works for classes with static event handlers— do I use level.isClientSide otherwise?

[Will Bradley]

Both are tools used to avoid running client-only code on servers, correct?

[Will Bradley]

Could you elaborate more? Specifically, is "distributions" referring to physical client vs. physical server? And what are the use cases for either method (@EventBusSubscriber vs Level#isClientSide)?

[Will Bradley]

Got it, thanks! And is it correct to assume most operations (say, Snowball#shoot) can be called without worrying about Level#isClientSide ?
