finale update

 When I started the project backup I started by adding an attack radius to the base tower. I also set it up to toggle show the radius which will be use to open the menu to upgrade, 

 I've added on the code for the enemy

class enemy(QGraphicsRectItem,QTimer):
    def __init__(self,parent=None):
        super(enemy, self).__init__(parent)
        self.setRect(0,75,75,75)
        self.check = 0
    def move(self):
        while self.x()<400:
            self.setPos(self.x() + 100, self.y())
        self.check = 1

temp = enemy()
temp.singleShot(1000,temp,temp.move)
scene.addItem(temp)

this code is supposed to make it move and it is more finished than last time it was seen. 

I found out why my code just stopped working the file somehow corrupted, but the code inside was fine so I grabbed a older version of the same code I had emailed to my self and copy and pasted the new stuff into it.
