Use when attack, vulnerability, grab, projectile, clash, trade, multi-hit, or duplicate-hit collision volumes need a deterministic gameplay contract.
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
# Hitbox and hurtbox Choose the representation required by the game: | Column | Shape | |---|---| | 2d-boxes | AABB / OBB on a gameplay plane | | 3d-capsules | body/limb capsules or other declared primitives | | projectile-volume | spawned gameplay volume with lifetime | ## Ownership and identity Hitboxes and hurtboxes are gameplay data, not render meshes. Active move ticks publish attack volumes; vulnerable state publishes hurt volumes independently. Each attack activation has a stable `attack_instance_id`. A multi-hit move additionally publishes a `hit_index` or equivalent schedule. Duplicate-hit prevention is keyed by attack instance, hit index and target according to the move policy; it is not inferred from overlap duration. Grab/throw, strike, projectile and clash volumes are distinct interaction classes. Eligibility rules decide which classes can affect the target. ## Same-tick resolution `query_hits` reads a logic-tick snapshot. Collect candidates before mutating reaction state so entity/container iteration order cannot erase a legitimate trade. Then resolve candidates through the project's explicit priority/trade/clash policy. …

How to install
mdr add jammyfu/open-game-skills/hitbox-hurtbox@sha256:2254ac7d9c768429The line at the top of this page pins the label git:20260913.43ccc40, 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.
