I am now thinking of implementing something like a barrier block in 1.7.10.
The barrier block itself was easy to make, but there is one other problem.
The problem is that if you have a block in your hand, it will show the block, and if you don't have a block in your hand, you will not see the block.
Please let me know if there is a way to solve this.
Thank you in advance.
