A addon for MCBE that despawns mobs no player can currently see (out
of FOV *and* behind a block) and restores them - position, rotation, health,
name tag - once a player can see that spot again. This is the same idea as
client-side "Entity Culling" mods, reimplemented server-side with the
`@minecraft/server` scripting API, since Bedrock add-ons can't hook the
renderer directly.
Built against **Minecraft Bedrock 1.26.40**, using `@minecraft/server` v2.9.0
(stable - no experimental/cheats toggles required).
📝How it works:
1. Every few ticks, each player's nearby entities are scanned
2. Entities are filtered down to ones that are safe to touch: no players,
no bosses, no villagers/traders, no leashed/ridden/inventoried mobs, and
(by default) no custom-named entities.
3. For each remaining candidate, we check whether *any* player can see it
('fov.js' for the view-cone test, `raycast.js` for the block-occlusion
test). An entity only counts as hidden if nobody can see it - this is
deliberately multiplayer-safe.
4. If an entity stays hidden for `cullDelayTicks` in a row (default 15
ticks, ~0.75s), its state is captured (`entityState.js`) into a small
persistent database (`database.js`, stored in world dynamic properties)
and the real entity is removed (`culling.js`).
5. On a second timer, every culled record is checked against current
player visibility. The moment a player could see that spot again, a
fresh entity is `/summon`-ed there and the saved state is reapplied
(`restore.js`).
6. `main.js` just wires all of the above together and registers the
`/cull:*` commands (`commands.js`).
