Block Placement

Block Placement is extremely important for Terraria builders, or just any other people. It can be triggered using the "Ctrl" Button on PC which either enables or disables the ''Smart Cursor. If you happen to have Smart Cursor on then it will show a little yellow square, and you can't place blocks wherever you ''want to. Then if you click Ctrl it might make it easier to build also having farther reach for block placement. However Smart cursor can be useful sometimes like when digging since it wont take forever to get every block out of the way when mining.
