TE not burning fuel.

Recommended Posts

Hey all!

 

So I was creating a 'coal generator' to create 'energy', however, I ran into some issues that I didn't know how to fix. Here are the issues:

Not Burning Fuel

On Reconnected, Items 'disappear' into your inventory, and cannot be interacted with, until you click the slot.

 

NOTE:

This is my attempt at creating a different TE and trying to learn from it. This was a learning experience, a lot of stuff WILL BE WRONG.

 

Here is the TE

First of all, rewrite your code to use

Capabilities

instead of

ISidedInventory

. Documentation on

Capabilities

can be found at mcforge.readthedocs.io.

 

For you issues, you can trace the execution of the code using breakpoints, so you can figure out how the code is working and why not.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

One issue though, changing it from ISidedInventory gave me errors on these lines, what whould I change this to.

 

  net.minecraftforge.items.IItemHandler handlerTop = new net.minecraftforge.items.wrapper.SidedInvWrapper( this, net.minecraft.util.EnumFacing.UP);
    net.minecraftforge.items.IItemHandler handlerBottom = new net.minecraftforge.items.wrapper.SidedInvWrapper(this, net.minecraft.util.EnumFacing.DOWN);
    net.minecraftforge.items.IItemHandler handlerSide = new net.minecraftforge.items.wrapper.SidedInvWrapper( this, net.minecraft.util.EnumFacing.WEST);

.. So something like this?

 

 

    @Override
    public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
    	  if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) {
    	    return (T) this.furnaceItemStacks;
    	  }
    	  return super.getCapability(capability, facing);
    }
