# About
\n**RayTraceAntiFreeCam** is a lightweight anti-freecam protection plugin that prevents players from interacting with blocks they should not be able to reach or \u201csee\u201d legitimately.<\/p>\n
## Important Note
\nThis plugin **does not detect** or prevent the client from moving its camera (freecam movement itself).
\nInstead, it blocks **illegitimate block interactions** (opening, clicking, breaking, placing, etc.) by validating that the target block is actually interactable from the player\u2019s eye position using a ray-trace \/ line-of-sight style check.<\/p>\n
## Features
\n– Blocks \u201cthrough-wall\u201d interactions
\n – Prevents opening containers (chests, barrels, shulkers, etc.) through blocks.
\n – Prevents using buttons, levers, doors, trapdoors, etc. through walls.
\n– Prevents illegitimate block breaking
\n – If the block is not realistically reachable\/visible, breaking is cancelled.
\n– Prevents illegitimate building\/placing via interaction filtering
\n – Placement attempts that rely on clicking blocks through obstacles are denied (handled via click validation).
\n– Reach-aware
\n – Uses the player\u2019s real interaction range attribute (when available) and applies configurable limits.
\n– Optimized for stability
\n – Avoids \u201crandom\u201d false positives caused by yaw\/pitch desync by not relying on the player\u2019s exact view direction.
\n – Uses short-term caching to keep decisions consistent while mining\/holding clicks.<\/p>\n
## Permissions
