Assignment #30 for IDT Diver X and Diver Y are visible so you can see how the diver's positioning is calculated in correlation to the shark. The sprite costume changes are 1. Diver is swimming 2. Angler Fish is switching between two different costumes to change direction. 3. Jellyfish is contracting and expanding to move, this uses two costumes. 4. The Shark uses costumes to have a swimming animation. 5. The Starfish did not require costume changes, as I rotated the sprite using coding. All sprites were drawn by me (excluding background, which was taken from the scratch library)
