Dynamic Entity Hitbox & Collision Visualizer

Dynamic Entity Hitbox is a developer and builder utility for Minecraft Bedrock Edition that visualizes entity bounding boxes and collision geometry in real-time. Whether you're debugging entity interactions, designing combat mechanics, or understanding entity positioning, this addon provides precise visual feedback on how Minecraft handles entity collision and detection.

🧾  Commands 

Use slash commands (/) for live config:

Command value Description /remove   removes debug shapes /tool   gives you a hitbox viewer tool /toggle   disable/enable the addon /settings   shows active settings /duration <ticks: number>(default: 400) Edits the duration of the non#toggle view time /radius <radius: number> (default: 5) Edits how far the hitboxes render (Tip: you can set it to a high value like 1000 to have ones behind you render too.) /size <size: number> (default: 10) Edits the max size of an entity hitbox § /refresh <refresh: number> (default: 5) Edits the refresh time for dynamic entities like shulkers and players. /maxcount <Entities: number> (default: 10) Edits the max amount of entities rendered per player. /mode [1 = hitbox, 2 = collisionbox, 3 = both] (default: both) Edit the mode the hitbox renders allowing you to see one or the other or both. (Only accepts the number codes) /includeplayers   toggle player hitboxes (default: false) /sendnumerics <value: boolean> (default: false) show numerical bounding box dimensions

🧠  Technical Bits

Uses system.runJob() for live updates

Ignores entities outside view

All visuals rendered with DebugBox, DebugLine

Static entities (entities that don't change hitbox size) are not refreshed but entities that do change are refreshed every 10 ticks (half a second)

Look vector ray (the blue line coming from the eye box) shows the true server side look direction of the entity 

Hitboxes are calculated using a ray system firing at the entity in all cardinal directions to determine the size accurately and dynamically so custom entities are supported
