Hi I have a custom chest that is lockable and unlockable,

 

I have found how to change the explosion resistance depending if its locked or not:

    @Override
    public float getExplosionResistance(BlockState state, BlockGetter world, BlockPos pos, Explosion explosion) {
        return state.getValue(IS_LOCKED) ? 1000000F : super.getExplosionResistance(state, world, pos, explosion);
    }

 

But can't find a method like there used to be to adjust the block hardness (i believe it was called getBlockHardnessLevel or something) which has obviously been removed in 1.18

 

Is there anything that has replaced it?

 

 

You will probably need to change the value through getDestroyProgress.

Looks like that was the way to go, cheers 👍
