Lesson Details
Key learning points
- A program can be written to move a sprite in four directions.
- The size of a sprite may need to be adjusted depending on the background.
- Algorithms can be translated into code.
- Code can be adapted by duplicating and changing the values.
Common misconception
The size of the sprite doesn't matter when programming movement.
Sprite size is important, especially in a maze, as if the sprite is too big it will touch the walls.
