Hey guys,

 

I have a problem with some custom leaves that causes a server crash shortly after being placed by a player. This is my first attempt at adding in custom trees, so most likely it's a mistake in my class. At the moment I'm not done making all the components for my custom trees, like saplings, gen and other stuff, so I'm not sure if the leaves will cause a crash when the game adds the trees, or if it's only a problem when a player places the leaves.

 

Here's the crash report

I would think that you guys would like to see the leaves class aswell.

 

 

public class EadoreLeaves extends BlockLeaves
{

public EadoreLeaves(String name)
{
	this.setUnlocalizedName(name);
	this.setRegistryName(name);
}

@SideOnly(Side.CLIENT)
public BlockRenderLayer getBlockLayer()
{
	return Blocks.LEAVES.getBlockLayer();
}

public boolean isOpaqueCube(IBlockState state)
{
	return Blocks.LEAVES.isOpaqueCube(state);
}

@SideOnly(Side.CLIENT)
public boolean shouldSideBeRendered(IBlockState state, IBlockAccess world, BlockPos pos, EnumFacing side)
{
	return Blocks.LEAVES.shouldSideBeRendered(state, world, pos, side);
}

@Override
public List<ItemStack> onSheared(ItemStack item, IBlockAccess world, BlockPos pos, int fortune)
{
	return Arrays.asList(new ItemStack(this, 1));
}

@Override
public EnumType getWoodType(int meta)
{
	return null;
}

}

 

 

java.lang.IllegalArgumentException: Cannot get property PropertyBool{name=check_decay, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in BlockStateContainer{block=em:leaves_poplar, properties=[]}

Seems pretty obvious to me: you should add the leaf properties to your leaf block. Look at

BlockOldLeaf

or [/code]BlockNewLeaf[/code] for reference.

Well... What seems obvious to you, might not be to someone who have never done it before... However, I'm not sure what to add. As I can see, I need to add something like this

{
public static final PropertyEnum<BlockPlanks.EnumType> VARIANT = PropertyEnum.<BlockPlanks.EnumType>create("variant", BlockPlanks.EnumType.class, new Predicate<BlockPlanks.EnumType>()
    {
        public boolean apply(@Nullable BlockPlanks.EnumType p_apply_1_)
        {
            return p_apply_1_.getMetadata() >= 4;
        }
    });

    public BlockNewLeaf()
    {
        this.setDefaultState(this.blockState.getBaseState().withProperty(VARIANT, BlockPlanks.EnumType.ACACIA).withProperty(CHECK_DECAY, Boolean.valueOf(true)).withProperty(DECAYABLE, Boolean.valueOf(true)));
    }
public IBlockState getStateFromMeta(int meta)
    {
        return this.getDefaultState().withProperty(VARIANT, this.getWoodType(meta)).withProperty(DECAYABLE, Boolean.valueOf((meta & 4) == 0)).withProperty(CHECK_DECAY, Boolean.valueOf((meta &  > 0));
    }

    /**
     * Convert the BlockState into the correct metadata value
     */
    public int getMetaFromState(IBlockState state)
    {
        int i = 0;
        i = i | ((BlockPlanks.EnumType)state.getValue(VARIANT)).getMetadata() - 4;

        if (!((Boolean)state.getValue(DECAYABLE)).booleanValue())
        {
            i |= 4;
        }

        if (((Boolean)state.getValue(CHECK_DECAY)).booleanValue())
        {
            i |= 8;
        }

        return i;
    }
protected BlockStateContainer createBlockState()
    {
        return new BlockStateContainer(this, new IProperty[] {VARIANT, CHECK_DECAY, DECAYABLE});
    }
}

 

However, this is from

BlockNewLeaf

class, and I can see that it uses an EnumType from BlockPlanks. Can I do it without an EnumType? Or do I have to make my own? I'm not adding my custom leaves as subBlocks, does that make a difference?

 

I know I'm a noob right now, but as I mentioned in OP, this is my first try at adding leaves, and I'm still learning.

you need to look at BlockOldLeaf and see how they do it then do the same.

 

Also when you register your model you need to ignore the decay and check decay properties otherwise it will tell you it can't find the properties.

If I ignore decay and check decay, doesn't that mean, that my custom leaves wouldn't behave as the vanilla leaves?

they behave like normal leaves.

 

you need to ignore those properties because when you register the model the model loader thinks those are model states  but in fact they are used to control leaf decay so are meta properties in this case.

 

if you don't ignore them you need to create a blockstate that has both those properties as true and false is stupid. you need like 8 states for a leaf model that only needs 1 state.

 

ModelLoader.setCustomStateMapper(MyLeafBlock, new StateMap.Builder().ignore(new IProperty[] {MyLeafBlock.DECAYABLE}).ignore(new IProperty[] {MyLeafBlock.CHECK_DECAY}).build());

Have a look at my leaf block custom base leaves block I created that can be extended and worked into any custom leaf you need. 

 

I also solved the fancy transparent leaves issue . When you turn fancy on leaves become transparent.

 

However you may still need to figure out how I register the model, the block and how my mod is structured coz i  got my own thing going . So you STILL need to learn to do all that yourself . If you just copy paste you won't understand anything.

Believe it or not, I actually had this almost done the same way as you, at a previous time, where it didn't work, but I was missing the CustomStateMapper. And it seems to have done the trick, so I thank you very much for your help
