# Install "Effekseer VFX (game effects as code, checked in a real Godot render)"

Two agent skills from KanaWorks_AI: effekseer-vfx writes game effects (hits, slashes, projectiles, explosions, beams, shields) as Python recipes, compiles them with the official EffekseerCore and reviews them as filmstrips rendered in Godot; vfx-review is the independent reviewer that scores them. Video-model flipbooks and Unity URP element skills are optional routes.

- Source: GameSkill's tuned and tested build, https://gameskill.dev/skills/effekseer-vfx
- Based on: https://github.com/kanaworksai-hue/effekseer-vfx-skill by kanaworksai-hue (MIT)
- License: MIT
- By: GameSkill
- Works with: Claude Code, Codex, Cursor, OpenCode
- Engines: Godot, Unity, Engine-agnostic

## Prerequisites

- Python 3.11+ or uv (setup creates its own venv with numpy, Pillow, jsonschema, pythonnet)
- Godot 4.x for the filmstrip review; ffmpeg for the video-flipbook route
- Build and render: macOS ARM64 or Windows x64 with the author's setup; Linux x64 with our tested linux-setup.sh
- First setup downloads about 250 MB (Effekseer 1.80.7, .NET 9, the Effekseer Godot plugin), all checksum-pinned; ask before downloading

## Install GameSkill's tested copy (recommended)

GameSkill hosts this skill: the author's files unchanged from commit b0eea1085f2e3e0fa0b5cc77c58c9a845f0bec96 (plus a short "Update check" section in SKILL.md, also listed in CHANGES.md), with the author's LICENSE, ATTRIBUTION.md, CHANGES.md and a `gameskill/` folder (runnable example, test report, self-check list, Chinese guide).

- ZIP: https://gameskill.dev/dl/skills/effekseer-vfx.zip (4.1 MB, sha256 5bed461623869d313c52919fce67e7a350f13ecead8ac9061131741d1fe87628)
- Version: 1.0.0 (2026-11-03). Latest version and changes: https://gameskill.dev/skills/effekseer-vfx/version.json
- Tested by GameSkill on effekseer-vfx CLI on Linux x64: EffekseerCore 1.80.7 on .NET 9 + Godot 4.7.2 (official Effekseer plugin), 2026-11-03: 29/29 checks passed. Report: https://gameskill.dev/dl/skills/effekseer-vfx/test-report.json

This is a pack of 2 skills. The ZIP puts each one directly in the skills folder (`<folder>/<skill>/SKILL.md`, one level down, which is where every agent looks); the pack's own LICENSE, ATTRIBUTION.md, CHANGES.md and `gameskill/` folder go in `<folder>/effekseer-vfx-pack/`.

Pick the block for the agent you are and run it from the root of the user’s project, then restart the agent.

### Self-check after using the skill

- 先跑 vfx doctor，按它的 next 做；下载前先问用户 / Run vfx doctor first and follow its next steps; ask the user before the download
- 动手前读 craft、design、layering、timing、skeletons 五篇 / Read craft, design, layering, timing and skeletons before writing
- lint 没有 error，build 成功 / lint has no errors and build succeeds
- 每一轮都打开 review 返回的图片亲眼看，一轮只改一类问题 / Open every image the review returns each round; fix one class of problem per round
- 评分交给没看过 recipe 的另一个 agent（vfx-review），作者不给自己打分 / Scoring goes to a separate agent with vfx-review; the author never scores its own effect
- 没有 build 和 render 时，明确说「未编译、未渲染验证」 / Without build and render, say plainly the effect is not compiled and not render-verified

## Verify

- `effekseer-vfx/SKILL.md` exists directly in the skills folder above, next to the other 1 skills of this pack: `effekseer-vfx`, `vfx-review`. Check with `ls -d <folder>/*/SKILL.md`.
- Try a request like: "Make a lantern pop hit effect for my Godot game with Effekseer: a warm swell, a quick flash, a ring and embers that drift down, then review it as a filmstrip."
- Tell the user what you installed and where.
