Using Python, create an actor model/module, including a control_actors_action.py file for the game "Batter" aka "Brick Breaker":
Here's what I have so far (I have the drawn objects, points, etc so far, just need to control how movement works for actors with a velocity greater than zero):

Thanks in advance!
Overview Batter is a game in which the player seeks to bat the ball back towards the top of the screen to break the bricks. Miss the ball and its game over! Rules Batter is played according to the following rules. 1. The bricks are arranged in 4 rows and 70 columns at the top of the screen. 2. The bat (or paddle) is positioned near the bottom of the screen. 3. The player can move the bat left or right within the boundaries of the screen. 4. The ball moves of its own accord, bouncing off the bat, bricks and walls. 5. If the bat misses the ball the game is over.
