[1.7.2] Making a Custom Rendered Block Flammable


Thornack

Recommended Posts

I have added a 3D Custom Rendered Block that has a custom model called BlockCampfire. I have been trying to make it flammable and havent found any way to do so. Does anyone know how I could achieve this functionality. My block is directionally placeable and It shows up in game properly with the appropriate hitbox. I have been trying to make this block ignitable like netherrack is so that it burns until it is put out. But the netherrack class doesnt implement anything to do with fire. I havent been able to dig up any documentation on how the infinite burning works for netherrack and am confused as to how to implement flammability to a block so that it may be ignited in game by the flint and steel. Here are my classes that render the Block

 

 

BlockCampfire.java

public class BlockCampfire extends BlockContainer {


public BlockCampfire(Material material) {
	super(material);
	this.setHardness(3.0f);
	this.setResistance(5.0f);
	this.setStepSound(soundTypeGrass);
	this.setBlockBounds(0F, 0F, 0F,1F,0.1F,1F);
	this.setCreativeTab(CommonProxy.CustomModTab);

}


 public void onBlockPlacedBy(World world, int i, int j, int k, EntityLiving entityliving)
     {
             int l = MathHelper.floor_double((double)((entityliving.rotationYaw * 4F) / 360F) + 2.5D) & 3;
             world.setBlockMetadataWithNotify(i, j, k, l, 2);
             System.out.println(l);
            
     }



public boolean isOpaqueCube(){
return false;
}

public boolean renderAsNormalBlock(){
return false;
}

@Override
public int getRenderType(){
int id;
id = RenderingRegistry.getNextAvailableRenderId();
return id;

	return new TileEntityCampfire();
}

@Override
    public void onBlockPlacedBy(World world, int i, int j, int k, EntityLivingBase entityliving, ItemStack itemStack)
    {
        int facingDirection = MathHelper.floor_double((double) ((entityliving.rotationYaw * 4F) / 360F) + 0.5D) & 3;
        int newFacing = 0;
        if (facingDirection == 0)
        {
        	newFacing = 2;
        }

I have found the method you pointed me to but I am unsure as to how to add it to my block

  @Override
 public boolean isFireSource(World world, int x, int y, int z, ForgeDirection side)
    {
        if (this == Blocks.netherrack && side == UP)
        {
            return true;
        }
        if ((world.provider instanceof WorldProviderEnd) && this == Blocks.bedrock && side == UP)
        {
            return true;
        }
        return false;
    }

When I add

this.isFireSource(world, x, y, z, UP);

to my constructor I get errors that tell me the variables are undefined

I created that method in my block class and I am overriding it.

 

public class BlockCampfire extends BlockContainer {


public BlockCampfire(Material material) {
	super(material);
	this.setHardness(3.0f);
	this.setResistance(5.0f);
	this.setStepSound(soundTypeGrass);
	this.setBlockBounds(0F, 0F, 0F,1F,0.1F,1F);
	this.setCreativeTab(CommonProxy.custommodTab);
	this.setLightLevel(10F);

	}


 public void onBlockPlacedBy(World world, int i, int j, int k, EntityLiving entityliving)
     {
             int l = MathHelper.floor_double((double)((entityliving.rotationYaw * 4F) / 360F) + 2.5D) & 3;
             world.setBlockMetadataWithNotify(i, j, k, l, 2);
             System.out.println(l);
            
     }

 @Override
 public boolean isFireSource(World world, int x, int y, int z, ForgeDirection side)
    {
        if (this == CommonProxy.blockCampfire && side == UP)
        {
            return true; }
		return true;}
        
   


public boolean isOpaqueCube(){
return false;
}

public boolean renderAsNormalBlock(){
return false;
}

@Override
public int getRenderType(){
int id;
id = RenderingRegistry.getNextAvailableRenderId();
return id;
}
@Override
public TileEntity createNewTileEntity(World world, int var2) {
	return new TileEntityCampfire();
}

@Override
    public void onBlockPlacedBy(World world, int i, int j, int k, EntityLivingBase entityliving, ItemStack itemStack)
    {
        int facingDirection = MathHelper.floor_double((double) ((entityliving.rotationYaw * 4F) / 360F) + 0.5D) & 3;
        int newFacing = 0;
        if (facingDirection == 0)
        {
        	newFacing = 2;
        }
        if (facingDirection == 1)
        {
        	newFacing = 5;
        }
        if (facingDirection == 2)
        {
        	newFacing = 3;
        }
        if (facingDirection == 3)
        {
        	newFacing = 4;
        }
        TileEntity tileEntity = world.getTileEntity(i, j, k);
        if (tileEntity != null && tileEntity instanceof TileEntityCampfire)
        {
        	TileEntityCampfire tileEntityCampfire = (TileEntityCampfire) tileEntity;
        	tileEntityCampfire.setFacingDirection(newFacing);
            world.markBlockForUpdate(i, j, k);
        }
    }

@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister) {
	this.blockIcon = iconRegister.registerIcon(CustomMod.modid + ":"
			+ this.getUnlocalizedName().substring(5));
}

}

 

But it looks as if it isn't being called

I'm looking for a solution to the same problem for my woodchips. When I first made my woodchips block for 1.6 and earlier, I just edited BlockFire.java, but now I'm trying to use Forge, and I'm finding everything a lot harder to do.

 

I found several methods in Block.java: getFlammability, isFlammable, getFireSpreadSpeed; but for some reason I can't override them in my modblock class. I guess it might have something to do with protected variables. The Forge documentation says that they return Flammability and FireSpreadSpeed values, but I think this might be wrong, and they're simply returning the blockID of the block in question, which is then picked up by BlockFire.java in its setBurnRate method, at which point the blockIDs are matched with Flammability and SpreadSpeed values.

 

I thought I might cheat by popping in planks, and tricking fire into thinking that my woodchips were planks, but that doesn't change the fact that blockFireSpreadSpeed and blockFlammability are protected.

Yes I seem to have run into the same problem, I want to try and find a method that doesn't edit Minecraft base classes. So far no luck still. I have been looking at all of the methods you mentioned and haven't found out much yet, its still an unsolved problem.

Hi

 

The code from Block.isFireSource() certainly looks like it should do the trick

 

    /**
     * Currently only called by fire when it is on top of this block.
     * Returning true will prevent the fire from naturally dying during updating.
     * Also prevents firing from dying from rain.
     *
     * @param world The current world
     * @param x The blocks X position
     * @param y The blocks Y position
     * @param z The blocks Z position
     * @param metadata The blocks current metadata
     * @param side The face that the fire is coming from
     * @return True if this block sustains fire, meaning it will never go out.
     */
    public boolean isFireSource(World world, int x, int y, int z, int metadata, ForgeDirection side)
    {
        if (blockID == Block.netherrack.blockID && side == UP)
        {
            return true;
        }
        if ((world.provider instanceof WorldProviderEnd) && blockID == Block.bedrock.blockID && side == UP)
        {
            return true;
        }
        return false;
    }

 

Have you tried

 

public class BlockCampfire extends BlockContainer {
[..]
@Override
public boolean isFireSource(World world, int x, int y, int z, ForgeDirection side)
{
  return (side == UP);
}        

 

When you light a fire on top of the campfire block using flint and steel, it should call your isFireSource.

 

@Spaceboot1:

> but for some reason I can't override them in my modblock class.

.. that means you must be doing something wrong because there's nothing special about those methods.  Show your code?

When I replace my .isFireSource method in

 public class BlockCampfire extends BlockContainer {


public BlockCampfire(Material material) {
	super(material);
	this.setHardness(3.0f);
	this.setResistance(5.0f);
	this.setStepSound(soundTypeGrass);
	this.setBlockBounds(0F, 0F, 0F,1F,0.1F,1F);
	this.setCreativeTab(CommonProxy.custommodTab);
	this.setLightLevel(10F);

	}

     {
             int l = MathHelper.floor_double((double)((entityliving.rotationYaw * 4F) / 360F) + 2.5D) & 3;
             world.setBlockMetadataWithNotify(i, j, k, l, 2);
             System.out.println(l);
            
     }

 @Override
 public boolean isFireSource(World world, int x, int y, int z, ForgeDirection side)
    {
        if (this == CommonProxy.blockCampfire && side == UP)
        {
            return true; }

    {
        int facingDirection = MathHelper.floor_double((double) ((entityliving.rotationYaw * 4F) / 360F) + 0.5D) & 3;
        int newFacing = 0;
        if (facingDirection == 0)
        {
        	newFacing = 2;
        }
        if (facingDirection == 1)
        {
        	newFacing = 5;
        }
        if (facingDirection == 2)
        {
        	newFacing = 3;

        {
        	TileEntityCampfire tileEntityCampfire = (TileEntityCampfire) tileEntity;
        	tileEntityCampfire.setFacingDirection(newFacing);
            world.markBlockForUpdate(i, j, k);
        }
    }

@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister) {
	this.blockIcon = iconRegister.registerIcon(CustomMod.modid + ":"
			+ this.getUnlocalizedName().substring(5));
}

}

 

 

with the code you suggested and then I try to light the flint nothing happens, and when I added System.out.println("UP");  to the method you suggested (above the return statement) nothing is displayed in the console suggesting that the method isnt being called

Hi DieSieben

 

You will have to set burn properties for your Block as well, otherwise the fire instantly removes itself when it's added.

 

Are you sure about that?

 

If I look through the code in BlockFire.onUpdate I see

 

            Block base = Block.blocksList[par1World.getBlockId(wx, wy - 1, wz)];

            boolean blockBelowIsFireSource = (base != null && base.isFireSource(par1World, wx, wy - 1, wz, par1World.getBlockMetadata(wx, wy - 1, wz), UP));

 

            if (!this.canPlaceBlockAt(par1World, wx, wy, wz))

            {

                par1World.setBlockToAir(wx, wy, wz);

            }

 

and

    public boolean canPlaceBlockAt(World par1World, int wx, int wy, int wz)

    {

        return par1World.doesBlockHaveSolidTopSurface(wx, wy - 1, wz) || this.canNeighborBurn(par1World, wx, wy, wz);

    }

 

i.e. so long as the block below isFireSource() and has a doesBlockHaveSolidTopSurface, it should sustain a fire above it, even if the other burn properties are not used?

 

@Thornack

Odd.  Try putting the breakpoint into BlockFire.updateTick() and then use your flint to light the top of the block.  Then trace through to see why it doesn't call your Block's method.

@TheGreyGhost

I am not sure how to add the breakpoint where you suggested as that would involve editing minecraft base classes wouldnt it? Im not sure how to go about doing that I know that you can find the class files in Referenced Libraries then forgeSrc-1.7.2-10.12.1.1060.jar and I have found the BlockFire.class file in package net.minecraft.block and the method you mentioned but I cannot edit it for some reason. When I try to put my System.out.println("UP"); into the method I simply cannot type anything or paste anything in. My Campfire block class looks like this

    }

@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister) {
	this.blockIcon = iconRegister.registerIcon(Soccer.modid + ":"
			+ this.getUnlocalizedName().substring(5));
}

}

 

where this method isnt being called when I try to light the block with flint

 

  @Override
 public boolean isFireSource(World world, int x, int y, int z, ForgeDirection side)
 {
  System.out.println("UP");
   return (side == UP);
 }

I am not sure how to add the breakpoint where you suggested as that would involve editing minecraft base classes wouldnt it? Im not sure how to go about doing that I know that you can find the class files in Referenced Libraries then forgeSrc-1.7.2-10.12.1.1060.jar and I have found the BlockFire.class file in package net.minecraft.block and the method you mentioned but I cannot edit it for some reason. When I try to put my System.out.println("UP"); into the method I simply cannot type anything or paste anything in.

Yeah an unfortunate side effect of the gradle setup is that it's a lot difficult to put testing statements into the vanilla code.  That's why you can't paste anything in.

 

But you can still use breakpoints in there (you're looking in the right place), which in this case should be all you need.

If you're not sure how to use them, try this

It's really quite awesome what you can do with the debugger and once you've learnt how to use it you'll wonder how you ever managed without it...

 

I don't see any obvious issues with the Campfire class, if you have no luck with the debugger, post a link to your project and I can download in the next couple of days to try it myself.

Yeah, when you consider that diesieben answered that in the second post. It makes it real real simple. Did he even get a thank you?

    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
