2D GAME ASSETS PACK

How to Build a 2D Game Asset Pack with Free AI

In this video, I show you how to build a complete 2D game asset pack using FREE AI tools.

We create:

• A professional character
• A full 2D animation
• Platforms and backgrounds
• UI elements
• A complete game-ready asset set

All without drawing manually.

Tools used:

– Mixboard (Character & Asset Generation)
– Grok (Animation)
– Blender (Green Screen & Export)

This workflow is perfect for:

Game Developers
Indie Developers
Unity & Unreal creators
AI Artists

Prompt to Grok

Create a 6-second animated video that simulates a 2D video game scene.

CRITICAL CHARACTER LOCK RULES

The character must remain 100% identical to the reference design.

– Do NOT change face, body proportions, hairstyle, colors, outfit, or details.
– Same character model in every frame.
– No redesign, no stylization changes, no random variations.

The top part of the frame is a reference image only.

It appears briefly at the very beginning (less than 1 second)
and then completely disappears.

ANIMATION

Create a 6-second continuous 2D action combo:

Combat idle → attack → dodge → jump → landing → hero idle.

NEGATIVE RULES

– No character redesign
– No extra characters
– No outfit changes
– No face changes
– No color changes
– No distortion
– No realistic 3D effects
– No cinematic camera

OUTPUT GOAL

A 6-second 2D game-style animation that looks like real gameplay,
with perfect character consistency.

You can experiment with different types of animations.

If you want to try a new animation style or action sequence,
replace only the ANIMATION section of this prompt with your new animation instructions.

You may choose:

– A single animation from the list
OR
– A combination of multiple animations blended together into one 6-second sequence.

Add a new set of advanced but gameplay-safe stylized cartoon actions, optimized for 12 FPS.

Motions must remain smooth, readable, and minimal in rotation.

No sharp spins.
No fast pivots.
No camera or perspective changes.

Advanced actions list

Dash (Short Burst)

• Very quick forward burst with strong anticipation
• 2–3 fast steps, then controlled stop

Dash Cancel to Idle

• Immediate soft recovery from dash into idle

Lean Forward / Lean Back

• Upper-body lean only, feet stay planted
• Useful for aiming or interaction states

Edge Balance

• Character balances near an edge
• Arms out slightly, small foot corrections

Ledge Grab (Static)

• Hands grip edge, body hangs with light swing
• Minimal movement, readable pose

Climb Up (Short)

• One clean pull-up motion
• Ends in stable standing idle

Drop Down
