Create Sprite Sheets
Generate game-ready sprite sheets with animation frames for idle, walk, run, and attack states.
Quick answer: Use the Character Sheet Maker tool through ToolRouter to create sprite sheets directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolEvery 2D game character needs a complete sprite sheet before it can be animated in the engine — and producing one from scratch is one of the most time-intensive steps in game development. Walk cycles alone require 6-12 frames, and that multiplies across every animation state.
Character Sheet Maker generates sprite sheets from a character concept, producing consistent frames for idle, walk, run, attack, and other states. Each frame maintains proportional accuracy and style consistency across the full animation range.
Independent game developers use this to prototype playable characters before investing in final art. Game jams rely on it to get functional characters in hours rather than days. Studios use it to explore multiple character concepts quickly before committing to one for full production.
How to create sprite sheets with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Generate game-ready sprite sheets with animation frames for all character movement states. Claude is ideal when you're developing the character concept alongside the sprite — deciding which states to prioritise, evaluating frame consistency, and planning the integration into the game engine.

How to create sprite sheets with Claude
Once connected (see setup above), use the Character Sheet Maker tool:
- Provide the character design and define the required animation states and frame count per state.
- Run `sprite_sheet` through `character-sheet-maker` to generate the animation frames.
- Ask Claude to evaluate the sprite sheet — are the frames consistent in style, do the motion arcs look natural, are there any proportion inconsistencies between frames?
- Revise flagged issues and export the sprite sheet in the correct dimensions for the target game engine.
Example prompt for Claude
Try this with Claude using the Character Sheet Maker tool
Use character-sheet-maker to generate a sprite sheet for this character with idle (4 frames), walk (8 frames), and attack (6 frames) states. Review the output for frame consistency and tell me whether the motion arcs look natural or need adjustment.
Tips for Claude
- Specify the frame dimensions upfront — 64x64 and 128x128 sprites require different levels of detail in the generation.
- Ask Claude to check whether the idle and walk cycles connect smoothly — a jarring state transition ruins the in-game experience.
- Export the sprite sheet in both the full grid format and individual frames for flexibility during engine integration.
Generate game-ready sprite sheets with animation frames for all character movement states. ChatGPT is effective when sprite creation is part of a full game character production package — generating the sprite sheet and writing the integration spec for the development team in the same session.

How to create sprite sheets with ChatGPT
Once connected (see setup above), use the Character Sheet Maker tool:
- Provide the character design and a list of required animation states with frame counts.
- Run `sprite_sheet` with `character-sheet-maker` to generate the full sprite sheet.
- Ask ChatGPT to write an integration note — frame dimensions, row layout, animation state names, and recommended frame rate.
- Deliver the sprite sheet with the integration note for the development team.
Example prompt for ChatGPT
Try this with ChatGPT using the Character Sheet Maker tool
Use character-sheet-maker to create a sprite sheet for our main character with idle, walk, run, and jump states. Return the sheet and write an integration note covering frame dimensions, row layout, and suggested frame rates for each animation state in Unity.
Tips for ChatGPT
- Specify the target engine (Unity, Godot, Phaser) so ChatGPT can tailor the integration note correctly.
- Ask for the sprite sheet in both horizontal strip and grid format if the engine preference is not yet confirmed.
- Document which row corresponds to which animation state — this becomes critical when the development team imports the sheet months later.
Generate game-ready sprite sheets with animation frames for all character movement states. Copilot is effective when sprite generation sits inside a game production pipeline where assets need to be documented and filed with technical specs immediately.

How to create sprite sheets with Copilot
Once connected (see setup above), use the Character Sheet Maker tool:
- Provide the character design and the animation state requirements.
- Run `sprite_sheet` through `character-sheet-maker` to generate the frames.
- Ask Copilot to document the sprite — state list, frame count, dimensions, and naming — for the asset library.
- File the sprite sheet with documentation for the development team.
Example prompt for Copilot
Try this with Copilot using the Character Sheet Maker tool
Use character-sheet-maker to generate a sprite sheet for this NPC character with idle and walk animations. Return the sheet and create a short asset spec with frame dimensions, state layout, and suggested use context for our game asset register.
Tips for Copilot
- Ask Copilot to write an asset spec immediately after generation while the parameters are fresh.
- Confirm the frame count and dimensions match the engine import settings before filing.
- Keep a version number in the filename from the start — sprite sheets get updated regularly as the game develops.
Generate game-ready sprite sheets with animation frames for all character movement states. OpenClaw is the best fit when you need sprite sheets for a full game roster — all characters, all animation states, at consistent dimensions and style.

toolrouter-mcp toolsHow to create sprite sheets with OpenClaw
Once connected (see setup above), use the Character Sheet Maker tool:
- Define the animation state schema — states per character, frame counts, dimensions — before batching.
- Run `sprite_sheet` with `character-sheet-maker` across the full character roster with locked parameters.
- Flag any characters with frame inconsistencies or motion artifacts and rerun only those.
- Export the complete roster sprite sheets with standardised naming for engine import.
Example prompt for OpenClaw
Try this with OpenClaw using the Character Sheet Maker tool
Use character-sheet-maker to generate sprite sheets for our 5-character game roster. Each character needs idle (4 frames), walk (8 frames), and attack (6 frames) at 64x64 pixels. Keep style consistent across all characters and flag any frame inconsistencies.
Tips for OpenClaw
- Lock frame dimensions and frame counts before batching — inconsistencies across the roster break engine import.
- Run a single character first as a style test before committing to the full roster batch.
- Define what a frame inconsistency looks like before review — proportion shift, style break, missing frame — so flagging is fast and objective.
