Specific Details: rowboat: The boat must be an existing pixel art object. It should move smoothly up and down, and slightly from side to side. motion: Vertical: The up and down movement must be slow and continuous, as if the boat were floating on gentle waves. horizontal: Add a small sideways wobble to simulate the rocking of the boat. Looping: The animation must be cyclical and without visible breaks, allowing a continuous loop. pictures: Use a sufficient number of frames to ensure smooth motion. We suggest between 6 to 12 frames for a complete cycle. Additional Tips: Pay attention to the physics of movement to ensure the boat appears to actually be floating. Consider the harmony between vertical and horizontal movement speed for a more realistic effect.
