Lightning bolt effect: a jagged procedural path with a glow shader, end sparks and screen shake.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# lightning — Procedural Jagged Bolt A lightning bolt is a noisy line from A to B, drawn for ~150 ms with a glow shader, sparks at both endpoints, and camera shake on cast. The recipe builds the jagged path in GDScript (midpoint displacement on a polyline), feeds the verts into an `ImmediateMesh`, applies a `ShaderMaterial` for additive bloom + flicker, spawns `vfx-hit-spark` particles at each endpoint, and calls `CameraShake.add_trauma(0.6)` for the impact. Used for shock spells, tesla coils, weapon discharges, electric enemies. ## When to use - "Cast a lightning bolt from the wizard's hand to the enemy." - "Chain lightning from one enemy to the next." (call `cast_lightning` per segment) - "Tesla coil firing at the player every 2 seconds." - "Energy weapon laser." (use the `plasma-laser` variant) - "Lightning strike from the sky." - The user wants a *short, dramatic* energy connection between two points. ## When NOT to use - The user wants a continuous beam that holds (e.g., laser sniper holding the trigger) — use the same shader on a `MeshInstance3D` cylinder with continuous emission, not the `ImmediateMesh` one-shot pattern. (See the `plasma-laser` variant.) …

How to install
mdr add summerengine/summer/vfx-lightning@sha256:1c47893ef9ee9614The line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
