OK I got another problem now.
186 C:\Users\Documents\TowerDefense\main.cpp request for member Draw' ingTower’, which is of non-class type `Tower ()()’
^ That is the error I am getting now. What I want to do is, is so that when the user clicks somewhere within the screen bounds, a tower will be drawn onto the location of the screen, while also subtracting money from the player.
Code:
