API Documentation

The API jar comes with all the source files for it, so there is documentation and general comments there. If there is anything in particular you're unsure about then feel free to ask here too.

You'll need to implement IEnergySource on your generator tile entity, post an EnergyTileLoadEvent when your tile is loaded and an EnergyTileUnloadEvent when it is unloaded. You can take a look at BasicSource if you'd like something that can handle (nearly) everything for you, or just as an example of what you might need to do.

You'll need to implement IEnergySink if you want it to accept power too, but otherwise yes. If your block is like an MFE in that it stores the power it can accept and send, implementing IEnergyStorage is probably a reasonable idea. If you want a BasicSource equivalent it'd be worth looking at BasicSinkSource.

If you're using 1.10 or above it would be

IRecipeInput input = Recipes.inputFactory.forStack(new ItemStack(Items.EMERALD));

Otherwise (ie using 1.9 or below) it would be

IRecipeInput input = new RecipeInputItemStack(new ItemStack(Items.EMERALD));
