getting hardness from a block

[winnetrie]

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"

[Matryoshika]

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?

[winnetrie]

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.

[winnetrie]

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

[Mattizin]

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

[winnetrie]

Something like this.:

 

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

that gives me an error saying to replace getBlockHardness with getBlock

[Choonster]

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.

[larsgerrits]

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?

[Draco18s]

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.

[winnetrie]

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

 

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!
