how to check what block gets right clicked by your item, and then replace it to another block, but with the same blockstate as the first block?

 

I know I have to use the "onItemUse" method but don't know what to put after the 'if'

 

this is what I got so far....

public ActionResultType onItemUse(ItemUseContext context) {
World world = context.getWorld();
    BlockPos blockpos = context.getPos();
    BlockState blockstate = world.getBlockState(blockpos);
    BlockState block = blockstate.getBlockState();
    if (block != null) {

What do you mean by this? The blockstate includes the block, so if you want the same blockstate that also means its the same block.

I meant same rotation..

Not all rotatable blocks use the same block state properties.
