Lab$8$A: Create a Pygame Display that is $400400.$ Create a Rect

that is $50400$ and place it along the center of the Display, blitting to

the Display a red Surface at the Rect's coordinates.

Create a Rect that is $5050$ and place its left border at the center of

the left border of the Display. Blit to the Display a blue Surface at

the Rect's coordinates.

Move the blue Rect from the left to the right of the Display at a speed

of $5,$ and then back again from the right to the left. Repeat this cycle

until the user closes the program.

Using colliderect$(),$ change the red Surface to green whenever

the two Rects are colliding, and change it back to red when the

two Rects are not colliding.

Lab$8$B: Expand on Lab$8$A by having two more Rects with associated blue

Surfaces, one which bounces along the bottom border of the Display at a speed

of $20,$ and one which bounces along the top border at a speed of $10.$

Using collidelist$()$ or collideall$(),$ change the red Surface's color to green

whenever ANY of the other three blue Surfaces' Rects collide with the red

Surface's Rect. Change the Surface color back to red if no collision is

occurring.

Lab$8$C: Create a Display that is $500500.$ Create a Rect that

is $5050,$ placing it at the center of the Display. Blit to the

Display a blue Surface at the Rect's coordinates and with the

Rect's dimensions.

Read from the Event Queue, taking the following actions:

If the user presses w$,$ move the Rect up $5.$

If the user presses s$,$ move the Rect down $5.$

If the user presses d$,$ move the Rect $5$ to the right.

If the user presses a$,$ move the Rect $5$ to the left.

If the user presses r$,$ place the Rect back at the center

of the Display.

Do not allow the user to go offscreen. In the example above, you can see at the bottom right which

key is being pressed. You do not need to include what key is being pressed to your Display. It is
