Hey there,

 

So I'm having an issue with one of my items, in which I'm casting IEnergyStorage to Capability.Energy.

 

However, I'm getting a crash saying that I cannot cast it to each other. This worked in 1.10 however.

 

java.lang.ClassCastException: com.lambda.plentifulmisc.items.base.ItemEnergy$EnergyCapabilityProvider$1 cannot be cast to net.minecraftforge.energy.IEnergyStorage

Here is the item:

    @Override
    @SideOnly(Side.CLIENT)
    public void getSubItems(Item item, CreativeTabs tabs, NonNullList list){
        ItemStack stackFull = new ItemStack(this);
        if(stackFull.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stackFull.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage != null){
                this.setEnergy(stackFull, storage.getMaxEnergyStored());
                list.add(stackFull);
            }
        }

        ItemStack stackEmpty = new ItemStack(this);
        this.setEnergy(stackEmpty, 0);
        list.add(stackEmpty);
    }

    @Override
    public boolean showDurabilityBar(ItemStack itemStack){
        return true;
    }

    @Override
    public double getDurabilityForDisplay(ItemStack stack){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage != null){
                double maxAmount = storage.getMaxEnergyStored();
                double energyDif = maxAmount-storage.getEnergyStored();
                return energyDif/maxAmount;
            }
        }
        return super.getDurabilityForDisplay(stack);
    }

    @Override
    public int getRGBDurabilityForDisplay(ItemStack stack){
        EntityPlayer player = PlentifulMisc.proxy.getCurrentPlayer();
        if(player != null && player.worldObj != null){
            float[] color = AssetUtil.getRGB(player.worldObj.getTotalWorldTime()%256);
            return MathHelper.rgb(color[0]/255F, color[1]/255F, color[2]/255F);
        }
        return super.getRGBDurabilityForDisplay(stack);
    }

    public void setEnergy(ItemStack stack, int energy){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage instanceof CustomEnergyStorage){
                ((CustomEnergyStorage)storage).setEnergyStored(energy);
            }
        }
    }

    public int receiveEnergyInternal(ItemStack stack, int maxReceive, boolean simulate){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage instanceof CustomEnergyStorage){
                ((CustomEnergyStorage)storage).receiveEnergyInternal(maxReceive, simulate);
            }
        }
        return 0;
    }

    public int extractEnergyInternal(ItemStack stack, int maxExtract, boolean simulate){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage instanceof CustomEnergyStorage){
                ((CustomEnergyStorage)storage).extractEnergyInternal(maxExtract, simulate);
            }
        }
        return 0;
    }

    public int receiveEnergy(ItemStack stack, int maxReceive, boolean simulate){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage != null){
                return storage.receiveEnergy(maxReceive, simulate);
            }
        }
        return 0;
    }

    public int extractEnergy(ItemStack stack, int maxExtract, boolean simulate){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage != null){
                return storage.extractEnergy(maxExtract, simulate);
            }
        }
        return 0;
    }

    public int getEnergyStored(ItemStack stack){
        if(stack.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stack.getCapability(CapabilityEnergy.ENERGY, null);
            if(storage != null){
                return storage.getEnergyStored();
            }
        }
        return 0;
    }

 

All these lines do this:

        ItemStack stackFull = new ItemStack(this);
        if(stackFull.hasCapability(CapabilityEnergy.ENERGY, null)){
            IEnergyStorage storage = stackFull.getCapability(CapabilityEnergy.ENERGY, null);

 

Thanks.

Usually, I don't like doing this, find it kinda scummy :^|

 

*cough*

 

Well, maybe not all that useless, Some Update on the situation:

Anytime I open the Creative Tab it crashes with the same error, but during Pre-Init I get:

I still can't find a reason, I'm almost certain these can be cast, especially since the IDE isn't giving me an error :/

            for(int i = 0; i < player.inventory.getSizeInventory(); i++){
                ItemStack slot = player.inventory.getStackInSlot(i);
                if(StackUtil.isValid(slot)){
                    int extractable = this.extractEnergy(stack, Integer.MAX_VALUE, true);
                    int received = 0;

                    if(slot.hasCapability(CapabilityEnergy.ENERGY, null)){
                        IEnergyStorage cap = slot.getCapability(CapabilityEnergy.ENERGY, null);
                        if(cap != null){

                        }
                    }

                    if(received > 0){
                        this.extractEnergy(stack, received, false);
                    }
                }

I love that this is such a simple issue yet you keep posting things that have nothing to do with the issue.

The issue is that whatever you are RETURNING from getCapability is NOT following the capability contract.

This has nothing to do with calling/using the cap. It has everything to do with what you're returning.

So, whatever your implementation of getCapability is, show us.

com.lambda.plentifulmisc.items.base.ItemEnergy

Give us that entire class.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

      Can Someone help me understand this?

      By 3.1459 · Posted

      I recently updated my mods and now my game is crashing on startup i tried adding them one at a time and couldn't find anything wrong and no crash log is being made the only thing I have is the debug log. If it helps I'm also using the curseforge launcher to launch the game. Minecraft version- 1.20.1 Forge Version-47.2.0 https://gist.github.com/keepinitreal247/d3105af6bb70e30f183505715113c61a

      [1.20.1] Rendering quads using VertexConsumer/RenderTypes

      By lggv · Posted

      Hi, I'm trying to render a single quad in the world. I'm mixing into the ChestRenderer class. If I understand correctly, BufferSource#getBuffer opens a buffer according to the supplied RenderType (Quads with POSITION_COLOR in my case). Then, I can supply my vertices (a simple 1-block plane along the Z Axis) and close the buffer using BufferSource#endBatch for rendering. This is the code I'm using: @Inject(at = @At("TAIL"), method = "render(...)V") public void render(T blockEntity, float partialTick, PoseStack poseStack, MultiBufferSource multiBufferSource, int packedLight, int packedOverlay, CallbackInfo ci) { BlockPos pos = blockEntity.getBlockPos(); AABB box = new AABB(pos, pos.offset(1, 1, 1)); BufferSource buffer = Minecraft.getInstance().renderBuffers().bufferSource(); VertexConsumer consumer = buffer.getBuffer(RenderType.guiOverlay()); poseStack.pushPose(); poseStack.translate(-pos.getX(), -pos.getY(), -pos.getZ()); consumer.vertex(box.minX, box.maxY, box.minZ).color(1, 1, 1, 1).endVertex(); consumer.vertex(box.minX, box.maxY, box.maxZ).color(1, 1, 1, 1).endVertex(); consumer.vertex(box.minX, box.minY, box.maxZ).color(1, 1, 1, 1).endVertex(); consumer.vertex(box.minX, box.minY, box.minZ).color(1, 1, 1, 1).endVertex(); buffer.endBatch(RenderType.guiOverlay()); poseStack.popPose(); } However, the plane does not get rendered. However, if I replace those 4 vertices with a call to LevelRenderer#renderLineBox and set the RenderType to LINES, it works. Do I need something else to render planes other than the 4 edges of the quad? I used QUADS back in 1.8 where it was still the raw OpenGL type and it worked then. Or am I missing something else entirely? Thanks!
