Calm down. I understood what they are saying, but it just doesn't give me a clear idea of what I should be doing. I already know what server-side/client-side is.

OK. making a mod and this is the first mod that I've tried to complete. I've been referencing the source code for all of the support I've needed up until this point. I just can't for the life of me figure out how to add sounds to the mod. If you could link me to a YouTube video (because I've failed at looking there) that would be great.

I'm trying to make a block/entity that when you meet the requirements, will float up and start spinning extremely fast. I have tried looking at the ender crystal code, but I have no idea where to start from.
