Character sprites
Start with a player, enemy, or NPC. Specify the camera angle and how large the character will appear in the game.

How it works
From a silhouette to a run cycle
- 01 · Step 1
Describe Your Character
Start with one side-view pose. At game size, check that the arms, boots, and backpack still read clearly.
- 02 · Step 2
Set the color reference
Pick a small palette and save the pose as your reference. Carry the same colors, proportions, and gear into each frame.
- 03 · Step 3
Build the sprite sheet
Lay out six poses in equal cells. Play them in order and watch for slipping feet, flickering outlines, or a jump at the seam.

Create a 4-Frame Run Cycle
Turn a character reference into a side-view run cycle for a platformer.
Prompt
Create a four-frame pixel art run cycle for a side-view platformer character. Design a forest courier wearing a teal jacket, orange scarf, brown satchel, and boots. Use a 64×64 px canvas per frame. Show four distinct running poses in one horizontal row, with consistent character proportions, colors, and ground alignment. Keep the pixel outlines clean and the movement easy to follow.
- Character design stays consistent across all six frames
- Feet meet the same ground line
- The last frame flows back into the first

Animation frames
Develop idle, walk, or run frames from the same character reference. Check the loop before adding more actions.
Matching 2D props
Use the character palette and camera angle as a brief for pickups, obstacles, and scenery.
Step by step
How to Make a Sprite Sheet with AI
Learn how to turn a character idea into a sprite sheet, refine your animation frames, and prepare the result for your 2D game.
Describe the character and action
Open SeeleAgent Workspace and describe your character's appearance, pixel art style, viewing angle, and movement. For example, create a side-view forest courier with a teal jacket and orange scarf, then request a four-frame running animation.
Map the states and lay out the frames
Name each state, its frame count, and whether it loops. For the courier’s run, ask for six 64 × 64 px cells in one row. Specify playback order, a shared baseline, and a transparent background.
Generate and review the loop
Play the frames at game size. Watch the feet at contact and the transition from the last pose back to the first. If one frame jumps, ask to revise that frame and keep the approved poses.
Prepare the sheet for your game engine
If your output is a PNG sheet, check the transparency and cell size before slicing it in Unity or Godot. Set the pivots and frame timing, then test the loop in your scene.

Watch the courier’s run cycle
This illustrated example follows one courier from outline to color reference, then plays the six poses in order.

FAQ
Frequently asked questions
What is a sprite sheet?
A sprite sheet places several images on one canvas. A game can display individual cells in sequence to animate a character, or use the cells for separate items and effects.
What should I include in a sprite prompt?
Specify the camera angle, character silhouette, palette, frame size, and action. For an animation, also describe the poses and where the character touches the ground.
How do I keep a sprite consistent between frames?
Keep a reference pose and ask for the same proportions, colors, and frame size. Inspect the frames side by side to catch changes in the outline or ground line.
Can I make pixel art sprites?
Yes. Ask for pixel art and give a target size and palette. Review the result at the size it will occupy in your game, where outlines and contrast matter most.
Can I use a sprite sheet for UI or visual effects?
Yes. For a button confirmation flash, ask for four transparent 32 px frames that brighten, peak, and fade once. Keep the flash centered and check the sequence against the actual button background.
Can I use the result in Unity or Godot?
Both engines can slice a sprite sheet into frames. Before importing, check the file format, transparency, grid spacing, and frame order against your project settings.
Where do I generate and revise the sprite?
Send a prompt from this page to seeleAgent Workspace. Review the first pose there, then ask for the frames or revise individual poses.
