i know with this :

setHardness(hardness);

I can set the hardness of a block, but what if i want to use the hardness from an other block.

Let's say from hardened clay.

 

How do i achieve this?

I tried with .blockHardness but that says "field not visible"

The field

blockHardness

is

protected

, meaning only classes in the same package, OR sub-classes in other packages (classes that extend Block) can "see" this field.

 

This tells me that the class you are doing this in, is not a class extending

Block

.

What exactly are you trying to do?

Why do you need the

blockHardness

for a non-block class?

As i can see i am extending it:

 

public class BlockBrickedClay extends Block implements IMetaBlockName{

public static final PropertyEnum TYPE = PropertyEnum.create("type", BlockBrickedClay.EnumType.class);
public BlockBrickedClay(Material material, float hardness, float resistance) {
	super(material);
        setHardness(hardness);
        setResistance(resistance);
        setDefaultState(this.blockState.getBaseState().withProperty(TYPE, EnumType.WHITE));
        setUnlocalizedName(References.temBlocks.BRICKEDCLAY.getUnlocalizedName());
	setRegistryName(References.temBlocks.BRICKEDCLAY.getRegistryName());
	setCreativeTab(Tem.blockstab);
        
}
}

 

I am making a bricked version for the hardened clayblocks, just like you have bricked stone.

Now i instead of giving it manual the hardness, i want it to get it from the original hardened clayblock

 

The field

blockHardness

is

protected

, meaning only classes in the same package, OR sub-classes in other packages (classes that extend Block) can "see" this field.

 

Subclasses in a different package to the parent class can only access

protected

fields and methods from the parent class on

this

, they can't access

protected

fields and methods on other instances.

 

Since you can't access the field, override the getter method instead:

Block#getBlockHardness

. Rather than calling this method on the other

Block

directly, call

IBlockState#getBlockHardness

on the state of the block you want to get the hardness for.

But .getBlockHardness is deprecated. Is there another way then?

Block.getBlockHardness is, use the blockstate version with state as object.

Something like this.:

 

this.setHardness(Blocks.STAINED_HARDENED_CLAY.getBlockState().getBlockHardness());

that gives me an error saying to replace getBlockHardness with getBlock

But .getBlockHardness is deprecated. Is there another way then?

 

Despite being deprecated, it's the correct method to override. See LexManos' post on this here.

 

Block#getBlockState

returns the

Block

's

BlockStateContainer

, which isn't what you need here. Use

Block#getDefaultState

to get the

Block

's default

IBlockState

, then call

IBlockState#withProperty

get an

IBlockState

with each property set to the appropriate value.

I think you should be using

BlockStateContainer.getBlockHardness

, as that is what all the vanilla methods seem to call. Actually, most deprecated methods in the

Block

class are called by methods in

BlockStateContainer

.

There is no

BlockStateContainer#getBlockHardness

method because

BlockStateContainer

doesn't implement

IBlockState

itself, it contains the

Block

's valid

IBlockSate

s (hence the name).

 

There is a

BlockStateContainer.StateImplementation#getBlockHardness

method that implements

IBlockState#getBlockHardness

. You don't actually need to use the

BlockStateContainer.StateImplementation

class, you only need to use the

IBlockState

interface implemented by it.

My bad, overlooked that it was in a nested class...

If your block is a variation of clay, then maybe you could extend BlockHardenedClay instead of extending Block?

Is there something wrong with using IBlockstate#getHardness(World, Pos) and passing null?

 

No vanilla block gives a damn about the world and pos values passed.  No really.  The IBlockState passes off the call to the block method:

 

    @Deprecated
    public float getBlockHardness(IBlockState blockState, World worldIn, BlockPos pos)
    {
        return this.blockHardness;
    }

 

Which is overriden by nothing.

You have a point there, maybe i can try this.

The reason for what i try to do is because i think it looks nicer. It's not nessecary.

If i would create a lot of different blocks, i could use constants maybe.

An example i declare a constant as clayhardness and give it a value 10. So everytime i want to set a blocks hardness as hardened clay,

i fill in the clayhardness constant.

I think i have choices enough, but i do not understand all that blockstate stuff yet.

 

Thank you all!
