Fly Off the Edge

Part of the Projects section of Coddy's Godot journey. Lesson 13 of 36.

Thrust for a while and the ship drifts off the screen. In this game the screen wraps around. Fly off the right edge and you come back on the left. Fly off the bottom and you come back at the top.

Write one if per edge. Add or subtract the screen's width, so the ship keeps the distance it went past the edge:

if position.x < 0:
	position.x += 640
if position.x > 640:
	position.x -= 640

Do the same for y, with the height, 360.

Challenge

Medium

Wrap the ship around the screen.

After the ship moves, past the left or right edge (0 and 640), bring it back on the other side.
Do the same for the top and bottom (0 and 360).

Press Play and fly off the right edge: the ship comes back on the left. Then Check.
