[SOLVED] Problems with Fluid.

[SirTheori]

Hello,

 

I am currently working on a mod for Minecraft 1.7.2 using Forge, and I have ran into a problem.

 

The problem is that Minecraft crashes on loading after adding a fluid. Any help is much appreciated.

I am also implementing Buildcraft, Forestry and IC2 APIs but haven't used any of them yet.

ahmmm... shouldn't you register your blovks in preinit?

like:

 

 

        public static Block blockXYZ;


@EventHandler
public void preInit(FMLPreInitializationEvent event) {
	blockXYZ = new......;
}

 

 

 

Thats the way i do it...(Don't forget the thank you button!)

Of course, I was sure I had missed something obvious. Thank you for pointing it out!
