How would you make a tool in Roblox that creates food every time you click

You would have to make the tool track your mouse and detect where and when it clicked. As long as the mouse is not in oblivion(On the skybox, not a brick) you could make it clone a piece of food from the Lighting folder, set it's parent to Workspace, and teleport it to your mouse's pointer location. If you did not want to make it spawn on your mouse you could make it spawn on your head or at a set location too.
