I want to make a game where you can make a kingdom, and part of it is making walls for buildings. I want it to be so you click on the walls you want to use, then you left-click on the land, making one of the corners, and then you left-click again placing another one of the corners, and so on until you complete the building then when you complete the building it is registered as a building maybe using a variable.
sorry if this is too complicated
