Cheat commands

Cheat commands can be quite useful while testing the maps.

  • buddha - Alternative to god. Player can take damage, but their health never gets lower than 1hp.
  • fire - trigger entity(-ies) by name (the first argument) or the entity in front of the player (if the argument is not provided). The special name !cross also means the entity in front of the player. The second (optional) argument is either on, off or set allows to change the input trigger type. If the second argument is set, the third argument is expected which is a number to set (can be used to set the value for game_counter, etc.). Note: the player is passed as an activator.
  • give_inventory and remove_inventory - give or remove player inventory item.
  • set_global_state and set_global_value - see Global variables.

Client Commands

Some client commands are executed purely on client side without interacting with the server. Others are sent from client to the server (and usually can be bound to keyboard or mouse buttons).

Pure client commands:

  • hud_color - change the current HUD color (only available if hud_color.configurable feature is enabled).
  • test_particles - produce some particles. This is for ParticleMan testing.
  • dump_ammo_types_client - report ammo types as known to the client. Used for debugging.

Client commands sent to server:

  • nightvision - toggle nightvision (see Nightvision).
  • recruit_followers and disband_followers - fast ally recruiting, see Followers.

Server commands

To see the output of the following commands you must set developer cvar to 1 or higher.

  • report_ai_state - report AI state of all monsters with provided classname.
  • entities_count - print the current number of entities on the map at console.
  • calc_ratio - report a Calc Ratio of specified entity. See Math and Locus system.
  • calc_state - report state of specified entity (On or Off). See Master entities.
  • dump_ammo_types - report registered ammo types.
  • dump_precached_models and dump_precached_sounds - show the count and the list of precached models (including sprites and brush models) or sounds. Useful to keep track of the number of precached resources and to see what's exactly is being precached.
  • dump_sound_replacements - report sound replacements in use. See Sound replacement
  • dump_soundscripts - report soundscripts. See soundscript debugging

Server cvars

The following features are currently implemented as cvars, but they might be changed into the features configurable via featureful_server.cfg file.

  • pushablemode controls how func_pushables are pushed by a player.
    • -1 is for default Half-Life behavior before the anniversary update (the excessive acceleration is present).
    • 0 is for default Half-Life behavior in anniversary update.
    • 1 is for g-cont fix (used in some Xash3D mods). Allow player to push pushables by going back, left or right. Prevent excessive acceleration by ignoring the effect of +use when the regular forward push is applied.
  • pickup_policy controls how player can pick up items.
    • 0 is by touch only (like in Half-Life).
    • 1 is by pressing +use only.
    • 2 is for both by touch and pressing +use.
  • npc_tridepth. Triangulation depth to use when building paths for monsters. Possible values: 1, 2, 3. Note that higher values may affect the performance.
  • npc_tridepth_all. If set to 0, only player's followers and monsters in scripts will use the value specified by npc_tridepth as the triangulation depth, and other monsters will use the value 1. If set to 1, all monsters will use the value specified by npc_tridepth. Note that this may affect the performance.
  • npc_forget_enemy_time. If monster didn't observe its enemy for this amount of time (in seconds), the monster forgets about their enemy. Setting 0 means that monsters never forget their enemies (the standard behavior in Half-Life).
  • npc_active_after_combat. If set to 1, monsters will wander around a bit after the combat ends.
  • items_physics_fix - various attempts to fix some bugs with items that drop from breakables. Consult features/featureful_exe.cfg for the description.
