Awsome

that fixed it

oh ok.

I'm trying to make a custom capability wrapper for an item that stores a fluid and my game crashes when writing the capability data to NBT. Crash Report: ---- Minecraft Crash Report ---- // My bad.

So I've figured out so far that I need to create a capability wrapper class to store the data from the capability. Now my question is what do I put inside the getCapability() method override. Is it the same thing I would put in it if it was a TileEntity? Or do I put something different? EDIT: Another question: Do I return a new instance of my capability wrapper in the custom item's initCapabilities() method?

Did you run vanilla 1.15.2 first?

I want to add a custom recipe serializer to my mod that can take a json file specifyng an Ingredient as an input and produce a FluidStack as an output. I can't use IRecipe because that doesn't work with FluidStacks. If I could just get some tips as to where to look, it would be appreciated.

Thanks, that was what was causing it.

Can you elaborate more please? Do you want someone to make a mod that does that? Or do you want help with making a mod that does that?

Judging by the crash report, the mod causing the error is mystical world. It is looking for a class in patchouli, but you don't seem to have it installed, therefore your game crashes. Report it to the mod author.

I have 2 blocks that have a tile entity, both of which properly override the IForgeBlock::createTileEntity and IForgeBlock::hasTileEntity methods, but only one of them actually creates the tile entity when the block is placed down. v Links to source below v The working block: https://github.com/Awsomekeldeo/TechMod/blob/master/src/main/java/awsome/techmod/blocks/BlockFirebox.java Its TileEntity: https://github.com/Awsomekeldeo/TechMod/blob/master/src/main/java/awsome/techmod/tileentity/TEFirebox.java --------- The broken block: https://github.com/Awsomekeldeo/TechMod/blob/master/src/main/java/awsome/techmod/blocks/BlockCrucible.java Its TileEntity: https://github.com/Awsomekeldeo/TechMod/blob/master/src/main/java/awsome/techmod/tileentity/TECrucible.java Registration Class: https://github.com/Awsomekeldeo/TechMod/blob/master/src/main/java/awsome/techmod/registry/Registration.java

thank you, that fixed it!

line 124 is if (world.getBiome(blockPos) != null) {

nope, i added a check for if world.getBiome() is null and it still crashes Updated Default Implementation: package awsome.techmod.api.capability.impl; import awsome.techmod.api.capability.energy.CapabilityHeat; import awsome.techmod.api.capability.energy.IHeat; import awsome.techmod.util.MathUtil; import net.minecraft.nbt.CompoundNBT; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.Direction; import net.minecraft.util.math.BlockPos; import net.minecraft.util.math.BlockPos.PooledMutable; import net.minecraft.world.World; import net.minecraft.world.biome.Biome; import net.minecraftforge.common.util.INBTSerializable; import net.minecraftforge.common.util.LazyOptional; public class HeatHandler implements IHeat, INBTSerializable<CompoundNBT> { public TileEntity te; public float temperature = 0; public float maxTemperature; public boolean canCool; public boolean transmitsHeat; public HeatHandler(TileEntity te, float maxTemp, boolean canTransmitHeat) { this.te = te; this.maxTemperature = maxTemp; this.transmitsHeat = canTransmitHeat; this.temperature = getBaseTempBasedOnBiome(this.te.getPos()); } public HeatHandler heatProducer(TileEntity te, float maxTemp) { return new HeatHandler(te, maxTemp, true); } public HeatHandler heatConsumer(TileEntity te, float maxTemp) { return new HeatHandler(te, maxTemp, false); } public void setTemp(float temp) { if (temp < getBaseTempBasedOnBiome(this.te.getPos()) && !canCool ) { this.temperature = getBaseTempBasedOnBiome(te.getPos()); }else{ this.temperature = MathUtil.roundFloat(temp, 2); } } @Override public float getTemperature() { if (this.temperature < getBaseTempBasedOnBiome(this.te.getPos()) && !canCool) { return getBaseTempBasedOnBiome(te.getPos()); }else{ return MathUtil.roundFloat(this.temperature, 2); } } @Override public float getMaxTemperature() { return this.maxTemperature; } @Override public float changeTemp(float amount) { float oldTemp = this.getTemperature(); float newTemp = (maxTemperature - oldTemp < amount) ? maxTemperature : (oldTemp + amount); setTemp(newTemp); return newTemp - oldTemp; } @Override public boolean getInCoolingMode() { return false; } @Override public float drawHeatFromSide(BlockPos pos, Direction side) { if (!pos.equals(BlockPos.ZERO)) { PooledMutable blockPos = PooledMutable.retain(); blockPos.setPos(pos).move(side); World world = this.te.getWorld(); TileEntity tile = world.getTileEntity(blockPos); if (tile != null) { LazyOptional<IHeat> heatCap = tile.getCapability(CapabilityHeat.HEAT_CAPABILITY, null); IHeat heatHandler = heatCap.orElseThrow(() -> new IllegalArgumentException("Heat capability cannot be null")); if (heatHandler != null) { if (heatHandler.canTransmitHeat() == true) { float lossyTemp = (float) (heatHandler.getTemperature() * (7/8f)); lossyTemp = MathUtil.roundFloat(lossyTemp, 2); return lossyTemp; }else{ return this.getTemperature(); } }else{ return this.getTemperature(); } } } return 0; } @Override public CompoundNBT serializeNBT() { CompoundNBT tag = new CompoundNBT(); tag.putFloat("temperature", temperature); tag.putFloat("max_temperature", maxTemperature); return tag; } @Override public void deserializeNBT(CompoundNBT tag) { temperature = tag.getLong("temperature"); maxTemperature = tag.getLong("max_temperature"); } @Override public boolean canTransmitHeat() { return this.transmitsHeat; } @Override public float getBaseTempBasedOnBiome(BlockPos pos) { World world = this.te.getWorld(); PooledMutable blockPos = PooledMutable.retain(); blockPos.setPos(pos); if (world.getBiome(blockPos) != null) { Biome biome = world.getBiome(blockPos); float biomeTemp = biome.getTemperature(blockPos); float tempF = (float) (95.9451242/(1+(3.012462778*(Math.pow(Math.E, (-3.330913488*biomeTemp)))))); float temp = (tempF - 32.0f) * (5.0f/9.0f); blockPos.close(); return temp; } return 0; } @Override public void setThermalMode(boolean mode) { this.canCool = mode; } } Crash Report: ---- Minecraft Crash Report ---- // There are four lights!

thanks, that's probably it

thanks, that was exactly what I needed to do. The temperature reading now displays properly.

oh yeah, I could do that since I'm rounding the temperature to 2 decimal places anyways and I'm already using trackIntArray to track the burn time of fuel in it's fuel slot

As far as I can tell dataManager seems to be used exclusively for entities. So I'm not quite sure that would work for what I'm doing.

The float value is stored inside of a custom capability that the tile entity has. I'll check out dataManager and see if I can use that instead. Link to source: TileEntity: https://github.com/Awsomekeldeo/TechMod/blob/1.15-port/src/main/java/awsome/techmod/tileentity/TEFirebox.java Container: https://github.com/Awsomekeldeo/TechMod/blob/1.15-port/src/main/java/awsome/techmod/inventory/container/ContainerFirebox.java GUI: https://github.com/Awsomekeldeo/TechMod/blob/1.15-port/src/main/java/awsome/techmod/gui/FireboxScreen.java Capability: -Registration: https://github.com/Awsomekeldeo/TechMod/blob/1.15-port/src/main/java/awsome/techmod/api/capability/energy/CapabilityHeat.java -Default Implementation: https://github.com/Awsomekeldeo/TechMod/blob/1.15-port/src/main/java/awsome/techmod/api/capability/impl/HeatHandler.java -Capability Interface: https://github.com/Awsomekeldeo/TechMod/blob/1.15-port/src/main/java/awsome/techmod/api/capability/energy/IHeat.java

I have a tileentity that stores a temperature value as a float. I need the temperature to get sent to the container so that it can update the GUI on the client. I know I need to use a custom packet in order to send the value over to the client, but I don't exactly know where I should recieve the packet.

Here's what I'm trying to do: I want to make a machine that makes something when It's 3 inputs are filled, and a recipe is matched. I also want it to do it over time like a furnace does, but without using fuel. Here's the code I have so far: Block Class Tile Entity Class: Container Class: I just don't know where to start on adding the code for the actual machine crafting. So if anyone is willing to give me some advice, please do so.
