[1.10.2 | 1.11.2] [SOLVED] Energy Capability

Bektor · January 4, 2017

Hi.

When changing the default EnergyStorage class, so basically implementing my own using IEnergyStorage, do I need to register a new capability for and do I need a new interface for it? Or can I work with the default capability while using my own implementation of EnergyStorage?

Thx in advance.

You do not need to do anything capability related.

Well, the Forge energy system stuff uses capabilities, so I want to use them, too. I'm just wondering when I'm creating my own EnergyStorage class which is actually a slightly modified version (so it's using IEnergyStorage, but offers also more methods) of EnergyStorage (but does not extend it, it implements the same interface however), if I have to create in that case a new capability and a new interface or not...........

If you are using the forge capability system and that Capability is already registered you do not need to do any capability registering stuff. You can create new implementations whenever you want and use them as long as it ultimately implements IEnergyStorage.

Ok, thx. This is working, but somehow it does not save the energy. When I reload the world it just starts by 0 again while it was at 250 when I saved the world.

You dont read and write it in your TE.

Bektor · January 4, 2017

You dont read and write it in your TE.

Oh yeah, totally forgot and overlooked that. So I basically have to put the container stuff in there like that?:

@Override
public void readFromNBT(NBTTagCompound compound) {
	super.readFromNBT(compound);
	this.container.deserializeNBT(compound);
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
	this.container.serializeNBT();
	return super.writeToNBT(compound);
}

loordgek · January 4, 2017

no

//write
compound.setTag(name, serializable.serializeNBT());
//read
serializable.deserializeNBT(compound.getCompoundTag(name))

Bektor · January 4, 2017

no

//write
compound.setTag(name, serializable.serializeNBT());
//read
serializable.deserializeNBT(compound.getCompoundTag(name))

What is this serializable? The container variable??

loordgek · January 4, 2017

yes

Bektor · January 4, 2017

yes

Ok, I changed it and it does still not work.

	@Override
public void readFromNBT(NBTTagCompound compound) {
	super.readFromNBT(compound);
	//this.container.setEnergyStored(compound.getInteger("StoredJAE"));
	this.container.deserializeNBT(compound);
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
	//compound.setInteger("StoredJAE", this.container.getEnergyStored());
	compound.setTag("StoredJAE", this.container.serializeNBT());
	return super.writeToNBT(compound);
}

I also tried it with the setInteger thing, does still not work. Oh and deserializeNBT needs an NBTTAgCompound, so getTag does not work.

loordgek · January 4, 2017

this does not work?

    @Override
    public void readFromNBT(NBTTagCompound compound) {
        super.readFromNBT(compound);
        container.deserializeNBT(compound.getCompoundTag("StoredJAE"));
    }

what do you meen by

Yeah, overread the getCompoundTag. But even when using getCompoundTag, it gives me no errors anymore, but seems not to be able to save and load the data....

As you can see, the energy reaches 250, goes down again, and then up again etc. ... But I'm not removing energy from the block!

@Override
public void update() {
	if(this.hasWorld() && !this.world.isRemote) {
		if(!this.getWorld().provider.hasNoSky() && this.getWorld().canBlockSeeSky(this.getPos().offset(EnumFacing.UP))
				&& this.getWorld().getSkylightSubtracted() == 0 && this.container.getEnergyStored() != this.container.getMaxEnergyStored())
			this.container.receiveEnergy(2, false);

		final TileEntity tileEntity = this.getWorld().getTileEntity(this.getPos().offset(EnumFacing.DOWN));

		if(tileEntity != null && !tileEntity.isInvalid()) {
			if(tileEntity.hasCapability(CapabilityEnergy.ENERGY, EnumFacing.UP)) {
				IEnergyStorage consumer = tileEntity.getCapability(CapabilityEnergy.ENERGY, EnumFacing.UP);

				if(consumer != null)
					this.container.extractEnergy(consumer.receiveEnergy(this.container.getEnergyStored(), false), false);
			}
		}
		System.out.println(this.container.getEnergyStored());
	}
}

@Override
public void readFromNBT(NBTTagCompound compound) {
	super.readFromNBT(compound);
	//this.container.setEnergyStored(compound.getInteger("StoredJAE"));
	this.container.deserializeNBT(compound.getCompoundTag("StoredJAE"));
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
	//compound.setInteger("StoredJAE", this.container.getEnergyStored());
	compound.setTag("StoredJAE", this.container.serializeNBT());
	return super.writeToNBT(compound);
}

To be sure it's not a problem with isRemote stuff, I just added a little check for this, but it's still counting the energy somehow twice.

loordgek · January 4, 2017

put breakpoints on it and see what it does

Bektor · January 4, 2017

put breakpoints on it and see what it does

Ok, after setting a breakpoint in those two lines:

			this.container.receiveEnergy(2, false); (TileEntity)
	return this.canReceive() ? acceptedPower : 0; (BaseMPcontainer)

So, basically, I found now out that it seems to count perfectly until the number 10 was reached. At this point it starts for an unknown reason again by 2 and then 12 and then 4 and then 14 and then 6 and then 16 .....

I think it's clear what I mean. Oh and directly before the number 10 was reached the world has been fully loaded.

What does your custom implementation of EnergyStorage / IEnergyStorage look like?

shadowfacts · January 4, 2017

Ok, I changed it and it does still not work.

	@Override
public void readFromNBT(NBTTagCompound compound) {
	super.readFromNBT(compound);
	//this.container.setEnergyStored(compound.getInteger("StoredJAE"));
	this.container.deserializeNBT(compound);
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
	//compound.setInteger("StoredJAE", this.container.getEnergyStored());
	compound.setTag("StoredJAE", this.container.serializeNBT());
	return super.writeToNBT(compound);
}

I also tried it with the setInteger thing, does still not work. Oh and deserializeNBT needs an NBTTAgCompound, so getTag does not work.

Of course it doesn't work. In writeToNBT, you store the NBTTagCompound created by

this.container.serializeNBT()

in the root TileEntity tag but in the readFromNBT method, you try to deserialize it from the root tag instead of the sub tag.

You need to change the line in readFromNBT to:

this.container.deserializeNBT(compound.getCompoundTag("StoredJAE"));

Bektor · January 4, 2017

Ok, I got it now working. Don't ask me what the cause of the problem was... I've got no clue... Just fixed some bugs and it seems that one of those bugs caused the other problems. ^^
