Hello, I'm trying to add a smelting recipe to the Magma Crucible from TE, with  a custom item and a custom fluid. I've been looking for an answer for a few hours now, and I'm pretty sure it has something to do with CoFHLib's helpers, but I just can't find a solution. Much appreciated

You need to send an IMC message to

"ThermalExpansion"

by calling

FMLInterModComms.sendMessage

before the postInit phase or

FMLInterModComms.sendRuntimeMessage

during the postInit phase. The reason you can use both methods is because TE subscribes to

IMCEvent

(fired between init and postInit) and also explicitly checks for runtime IMC messages when

FMLLoadCompleteEvent

fires (after postInit). Some mods only subscribe to

IMCEvent

, so they won't process runtime messages.

 

As far as I can tell there's no formal documentation of TE's expected IMC format, but you can download a recent dev version and view the

IMCHandler

class in a decompiler to see how it handles each message.

 

You'll need to use

ItemStack#writeToNBT

and

FluidStack#writeToNBT

to write the inputs and outputs to the NBT message you send to TE.

 

Edit: I forgot some words.

Thanks, it worked !

 

NBTTagCompound concreteRecipe = new NBTTagCompound();
concreteRecipe.setInteger("energy", 300);
concreteRecipe.setTag("input", (new ItemStack(concretePowder).writeToNBT(new NBTTagCompound())));
concreteRecipe.setTag("output", (new FluidStack(concreteFluid, 1000).writeToNBT(new NBTTagCompound())));
FMLInterModComms.sendMessage("ThermalExpansion", "CrucibleRecipe", concreteRecipe);
