Moving sprites with position values
Rather than set active objects to move according to a move type (such as path nodes) I've used alterable values to set the horizontal and vertical when colliding with backdrops. So in my game the purple down-facing spider moves up and down the screen, changing direction when it hits a backdrop. Likewise with the left/right facing spider.
While these work great I have a few problems:
1. How do I change the speed of movement?
2. How do I have different speeds for each direction?
3. How do I change sprite facing direction of the left/right spider?
4. How do I add a movement delay when a sprite collides with a backdrop?
Here's my events:
