RayTrace Anti Entity ESP
A Paper plugin that prevents HACKERS from seeing entities (ex:Players) through walls.
It uses a DDA raytrace algorithm to check each entity's visibility per player every tick — entities hidden behind solid blocks are concealed at the packet level, meaning clients never receive data for entities they shouldn't see.

Configuration

checking:
enabled: true
period_ticks: 1 #How often to run the check loop in ticks (recommended: 1 when using stagger_groups)
stagger_groups: 3 #Divide entities into N groups, checking 1 group per tick for smooth CPU usage (1 = disabled)
distance_override: 10 #Entities within this many blocks are always shown (0 to disable)
bounding_box_extra_value: 0 #Expand entity bounding box for more lenient detection
vertices_layers: 4 #Sample points per entity (min 2, higher = more accurate)
perspective_checking:
enabled: true
distances_from_head: 4 #Simulated third-person camera distance in blocks
display_name:
enabled: true #Show a fake name tag above hidden entities
lookahead_ticks: 3 #Extrapolate the fake nametag's position this many ticks ahead to compensate for vanilla's client-side smoothing (0 disables extrapolation)
offset_y: 0 #Vertical offset of the name tag above the entity's head
debug:
enabled: false #Show block markers at raytrace vertices (testing only)
anti_entities:
- player
anti_mode: whitelist #Whitelist = only listed types | blacklist = all except listed
blacklisted_world: [] #Worlds where ESP checking never runs, by the viewing player's current world. Leave empty to run in every world.
