godot-shaders-basics — Claude Code skill: install and overview

Supplies Godot shader patterns for draw-call batching, post-processing, and foliage. Useful when building hit-flashes or screen passes without depth glitches.

What godot-shaders-basics does

This skill equips coding agents with practical rules for Godot Shading Language. It focuses on engine rendering bottlenecks rather than introductory color math. The model learns to configure instance uniforms for enemy nodes. This preserves single draw calls.

Included shader templates handle foliage wind sway and world position reconstruction from depth textures. Full-screen screen-space passes account for Godot 4.3 requirements. Because the engine uses Reversed-Z depth, screen quads require POSITION = vec4(VERTEX.xy, 1.0, 1.0) to prevent unwanted clipping.

Dynamic if/else checks are replaced by hardware-friendly functions like step() and mix(). Invariant calculations move to the vertex stage so fragment code remains lean.

What it helps with

  • implement damage flashes on instanced meshes without breaking batches
  • render screen-space post-process quads correctly in Godot 4.3 Reversed-Z
  • reconstruct world coordinates using scene depth textures
  • build foliage wind motion while preserving shadow casting via alpha scissor

Example prompts for the agent

  • Write a Godot hitflash shader using instance uniforms to preserve draw call batching
  • Generate a full-screen quad shader compatible with Godot 4.3 Reversed-Z depth
  • Build a dissolve shader that keeps shadows and depth prepass using alpha scissor

How to install godot-shaders-basics in Claude Code?

Run npx skills add thedivergentai/Game-Dev-Agentic-Skills --skill godot-shaders-basics -a claude-code in your terminal.

What does godot-shaders-basics do?

It adds production Godot shading templates and optimization rules for batch-safe effects to your AI assistant.

Why does the skill avoid unconditional discard operations?

Using discard prevents hardware depth prepass optimizations from functioning. The skill enforces ALPHA_SCISSOR or hash dithering so geometry still casts proper shadows.
