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.
