Entity

An entity refers to anything that the player can interact with in an Id Tech 3 map. Weapons, items, NPCs, doors and switches are all types of entities.

The static geometry of a map is also an entity, known as "worldspawn".

This article describes selected entities.

func entities

func entities are composed out of map geometry (brushes and/or curve patches).

func_breakable

This is used to create breakable walls, grates, and other structures.

func_door

A simple door.

func_rotating

A rotating structure, eg. a fan. Can be switched on and off.

func_static

In JO and JA, these are typically used to create objects which are moved by ICARUS scripts. For example, elevators, moving platforms and ramps.

func_train

An object that moves along a pre-defined path, set by path_corner entities.

func_usable

A object that can be visible ("on") and invisible ("off"). Typically used (together with a trigger) to create switches.

fx entities

These create local or global effects.

fx_rain, fx_snow and fx_wind create a global weather effect (appears throughout the entire map, in any "outside" areas).

fx_runner creates a local effect, from an .efx file.

misc entities

misc_ammo_floor_unit

An ammo recharge station.

misc_atst_drivable

An ATST walker that the player can drive. (Like in the Yavin Canyon SP map).

misc_camera

A security camera, which the player can look through.

misc_ion_cannon

Big ion cannon, used in Artus and Hoth SP maps.

misc_maglock

Magnetic lock, seals doors until destroyed by a lightsaber.

misc_model

Allows placement of a md3 (or .ase) model. Is converted into bsp.

misc_model_breakable

A breakable md3 model. Can also be moved by scripts and ROFF.

misc_model_static

A static (non-breakable) md3 model. Not converted into bsp.

misc_panel_turret

A gun turret that the player can control remotely.

misc_security_panel

Requires a matching item_security_key to unlock.

misc_shield_floor_unit

A shield recharge station

misc_skyportal

Creates a sky portal at the location.

misc_turret

A gun turret.

misc_weather_zone

Sets a region to check for weather contents (inside or outside brushes). Should be used with a weatherzone brush.

NPC entities

NPC_spawner

Used to spawn a custom made NPC.

NPC_vehicle

A vehicle.

point_combat

NPCs equipped with guns move to these locations to fight.

rail entities

These are special entities used to create a moving train / tram illusion, as in t1_rail.

It is in fact the scenery (buildings) which are moving, while the "train" is actually stationary.

target entities

target_level_change

Ends the current level.

target_scriptrunner

Runs an Icarus script.

target_speaker

Plays a sound. Can be assigned a SoundSet or a .wav file.

trigger entities

Triggers should be made entirely out of a brush (or brushes) textured with the trigger shader.

trigger_hurt

Does damage to players and/or NPCs. Can be set to an electrocution effect, or falling (pit) effect.

trigger_multiple

A standard trigger, which can be used to make switches (if "facing" and "use button" spawnflags are set).

trigger_once

Like trigger multiple, but can only be triggered once.

trigger_push

Pushes players and/or NPCs in a certain direction. Can be used to create wind tunnels and conveyor belts.

trigger_visible

A trigger which is triggered by being looked at. Can be set to force sight only.

waypoint entities

waypoint

These are used by NPCs (like Stormtroopers) for navigation. A map requires a network of connected waypoints; otherwise, NPCs will not be able to move around. Jedi and other lightsaber wielding NPCs do not require waypoints.

waypoint_navgoal

An NPC can be moved to this location with a script.
