WASD to move around If you want to add more objects to the world, go to the "object sprite". There is a moreblock called "Create New Object". Add those to a green flag event, to add new objects. To configure those objects, you need to set the arguments when you call the Create New Object block, there is a comment explaining what each argument does.
I could never get scrolling levels working too well back when I used to use scratch years ago. The project uses some basic vector math to calculate where objects should be placed relative to the camera based on their world positions. Known issues: - No proper layering system - No collision system - Can't handle moving objects - Can't handle animated objects - Adding new objects is a pain (no level editor)
