Game Cog

AI game development powered by CellCog. Character-consistent art, sprites, tilesets, music, UI, 3D models, GDDs, level design, game prototypes. Cohesive game assets across every modality from a single prompt.

Game Cog - Build Game Worlds, Not Just Sprites

Game development assets and prototypes with character consistency across all assets.

Game development is a multi-discipline problem — mechanics, art, music, UI, and level design all need to feel unified. CellCog reasons deeply about your game's vision first, then produces character-consistent art, tilesets, music, sound effects, UI elements, 3D models, and full game design documents — all cohesive from a single brief.

How to Use

For your first CellCog task in a session, read the cellcog skill for the full SDK reference — file handling, chat modes, timeouts, and more.

OpenClaw (fire-and-forget):

python

result = client.create_chat(
    prompt="[your task prompt]",
    notify_session_key="agent:main:main",
    task_label="my-task",
    chat_mode="agent",
)

All agents except OpenClaw (blocks until done):

python

from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
    prompt="[your task prompt]",
    task_label="my-task",
    chat_mode="agent",
)
print(result["message"])

What You Can Create

Character Design

Bring your game characters to life:

• Player Characters: "Design a cyberpunk samurai protagonist with multiple poses"

• Enemies: "Design a boss monster - corrupted tree guardian"
• Character Sheets: "Create a full character sheet with idle, run, attack poses"
• Portraits: "Generate dialogue portraits for my visual novel cast"

Example prompt:

"Design a main character for a cozy farming game:

Style: Stardew Valley / pixel art inspired but higher resolution Character: Young farmer, customizable gender, friendly expression

Need:

• Front, back, side views
• Idle pose
• Walking animation frames (4 directions)
• Tool-holding poses (hoe, watering can)

Color palette: Warm, earthy tones"

Environment & Tiles

Build your game worlds:

• Tilesets: "Create a forest tileset for a top-down RPG"
• Backgrounds: "Design parallax backgrounds for a side-scroller"
• Level Concepts: "Create concept art for a haunted mansion level"
• Props: "Generate decorative props for a medieval tavern"
• UI Elements: "Design health bars, inventory slots, and buttons"

Example prompt:

"Create a tileset for a dungeon crawler:

Style: 16-bit inspired, dark fantasy

Include:

• Floor tiles (stone, dirt, water)
• Wall tiles (brick, cave, decorated)
• Doors (wooden, iron, magic)
• Props (torches, chests, barrels, bones)
• Traps (spikes, pressure plates)

All tiles should seamlessly connect."

Game Concepts

Develop your game ideas:

• Game Design Documents: "Create a GDD for a roguelike deckbuilder"
• Story Outlines: "Write the main storyline for a sci-fi RPG"
• Mechanics Design: "Design a unique combat system for my action game"
• World Building: "Create the lore for a post-apocalyptic world"
• Pitch Decks: "Build a pitch deck for my indie game to show publishers"

Example prompt:

"Create a game design document for a mobile puzzle game:

Core concept: Match-3 meets city building Target: Casual players, 5-minute sessions

Include:

• Core loop explanation
• Progression system
• Monetization strategy (ethical F2P)
• First 10 levels design
• Art style recommendations

3D Models & Assets

Production-ready 3D models in GLB format for your game engine:

• Characters: "Create a 3D model of my RPG protagonist"
• Weapons & Items: "Generate 3D weapon models — sword, axe, bow, staff"
• Props: "Create 3D dungeon props — chests, barrels, torches"
• Vehicles: "Build a low-poly spaceship for my mobile game"
• Environment pieces: "Generate 3D trees, rocks, and buildings for my world"

CellCog handles the full pipeline — describe what you want, and it generates optimized reference images then converts to textured 3D models. Batch generation supported (e.g., "create 10 weapon models").

GLB output works with Unity, Unreal, Godot, Three.js, and Blender. Specify poly count and PBR materials for your target platform.

• Sprite Sheets: "Create a sprite sheet for a ninja character"
• Animated Effects: "Design explosion and hit effect animations"
• Items: "Generate icons for weapons, potions, and armor"

Chat Mode for Game Dev

Scenario	Recommended Mode
Individual assets, sprites, character designs, UI elements	"agent"
Full game concepts, complex world building, narrative design	"agent team"

Use "agent" for most game assets. Characters, tilesets, UI elements execute well in agent mode.

Use "agent team" for game design depth - full GDDs, complex narratives, or when you need multiple creative angles explored.

Tips for Better Game Assets

1. Specify dimensions: "32x32 tiles" or "1920x1080 background" prevents mismatched assets.

2. Reference existing games: "Style like Hollow Knight" or "Celeste-inspired" gives clear direction.

3. Think about implementation: Request assets in formats your engine can use. Mention if you need transparency, layers, or specific file types.

4. Consistency matters: When requesting multiple assets, describe your game's overall style guide so everything matches.

5. Animation frames: Specify frame count and whether you need sprite sheets or individual frames.

6. Consider your scope: Start with placeholder assets and iterate. Perfect is the enemy of shipped.
