Allow actors drawing a shape (instead of an image)

[aoloe]

When teaching the first steps with Pygame zero, kids tend to get lost in:

• Searching the right images for their game.
• Where did they download it? Where / what is the "images" directory?.
• Move the new images to the right directory.
• Make sure that the images are correctly named.
• Resizing the images!

Would it be possible to allow the actors to also use shapes like rectangles and squares?

I'm thinking of something like

paddle = Actor()
paddle.shape = Rect((x, y), (w, h))
paddle.color = r, g, b
# paddle.fill_color = r, g, b

def draw()
    paddle.draw_rect()
    # paddle.draw_filled_rect()

If there is an interest in this feature, I can work on a formal proposal and possibly produce a pull request.

This is a good idea - it's something that is already in Wasabi2D and works well (and is handy).

I'd suggest simply avoiding the Actor class though. We can create a new class like shapes.Rectangle() and expose shapes as a built-in.

I also thought about creating a new ActorShape class.

Still, I'm rather in favor of adding the feature to the Actor class. Keeping the same class would help the programmer start with a shape and later move to an image.

But I'm ok with other solutions.

If we put everything in the Actor, draw() might automatically draw a shape if one is defined... (also useful for checking the bounding boxes...)...
And do nothing if both the shape and the image are not defined.

seems you need Sprite class linke Sprite in ActionScript 3

pgzero is nice for teaching kids, Wasabi2D is powerful, but need more work making it out-of-box and lower floor for newbee.

Decorator maybe hard to understand for kids
