Thank you. It's work.

OK When I changed to this. @Override public boolean canHarvestBlock(EntityPlayer player, int metadata) { ItemStack stack = player.inventory.getCurrentItem(); if (stack.getItem() == Items.shears || stack.getItem() instanceof ItemSword) { return player.canHarvestBlock(this); } return false; } That crash again T_T

Please help!! I don't know why crash. T_T

Thank you very much. That's work!

That doesn't work. When I try to clean up the cache and setupDevWorkspace. Sorry!
