Create a 2D/3D Hybrid Sprite Game in Godot 4.3: State Machine Tutorial with LimboAI - Part 1/2

Summary of the tutorial content (Tech concepts / features)

Tutorial goal

Build a 2D/3D hybrid sprite character in Godot 4.3 using the LimboAI State Machine.

Part 1 focus (preparation)

Set up the Godot project and create a minimal playable 3D scene:

• 3D world floor with:
  • Mesh
  • Collision
• Player character built from:
  • CharacterBody3D
  • Sprite3D
• Basic movement using Godot’s built-in CharacterBody3D movement script template
• Camera + lighting so the scene is visible in-game

Beginner-friendly approach: The host contrasts this tutorial with a prior video that was mostly a showcase, emphasizing that this one is the actual learning tutorial.

Why state machines

A state machine helps organize character behavior (e.g., jump/crouch/attack) into efficient, scalable, maintainable code per state.

Key setup steps / implementation details

Install LimboAI add-on

• Use Godot’s AssetLib / download workflow to find the LimboAI add-on.
• Choose the correct version (4.3).
• Note: the installer may show errors, but the tutorial instructs to ignore/confirm them if nothing breaks.

---

Create scenes structure

• Create a Scenes folder in the project root.
• Make a main 3D scene named main for the world prototype.

---

Build the floor (static environment)

1. Add a StaticBody3D
2. Add MeshInstance3D
   • Use a BoxMesh
   • Floor dimensions (as shown): approximately 5 x 0.1 x 10
3. Add CollisionShape3D
   • Use a matching box shape with the same dimensions
4. Add a dirt texture
   • Save a provided texture into assets/textures/...
   • Apply it using SurfaceMaterialOverride
   • Use UV1 triple-repeat so the texture doesn’t look stretched

---

Create the player scene

1. Create an agents/player scene:
   • Extend CharacterBody3D
   • Add Sprite3D for the hybrid 2D/3D look
2. Import and use a sprite sheet:
   • Download a character sprite pack
   • Save the PNG into: assets/textures/agents/
   • Configure Sprite3D frame settings:
     • Horizontal frames: 16
     • Vertical frames: 25
3. Fix blurry/mushy sprite appearance:
   • Set texture filter to Nearest (prevents smoothing)
   • Enable Alpha cut → Discard
     • The tutorial claims this improves shadowing/appearance
   • In import settings:
     • Disable compression (e.g., compress 2 = Disabled)
     • Reimport so pixels stay crisp

---

Camera + lighting

• Add a Camera3D to the player scene (positioned above/behind).
• Add environment lighting by copying preview lighting:
  • Use “add sun to scene” / “add environment to scene”
  • This adds WorldEnvironment and DirectionalLight3D to the main scene

---

Make the scene actually run

• Add a CollisionShape3D to the player.
• Adjust collision and scale alignment:
  • The sprite is scaled up, and collision is aligned accordingly.
• Add a movement script:
  • Attach a default script to player
  • Use the editor checkbox for basic movement
  • Create script at: scripts/agents/player/player.gd
• The tutorial claims that at this point the basic game loop/movement works (no state machine yet).

What’s coming next (clear transition)

This video ends right before implementing the LimboAI state machine, after establishing:

• a working prototype world
• camera/lighting
• a properly configured sprite
• player collision and basic movement
