Additional Debugging Facilities

XashXT provides a number of debugging facilities intended for making a level designer's job easier. Most of these features are enabled through console variables or commands, but sometimes debugging is turned on for specific entities using special spawn flags (see the descriptions of new entities or revisions of existing entities) for details.

Listed below are console variables and commands, with usage details.

Note: Do not try to use these commands and variables as part of gameplay. Most of them will not work in user mode.

Console Variables

phys_debug	Enables collision rendering for the PhysX engine.
phys_qdebug	The current implementation only draws centres on func_door_rotating entities.
p_speeds	Outputs information about the current state of the PhysX engine and objects in the scene.
r_speeds	Takes values in the range from 1 to 9. Outputs miscellaneous information about the renderer state.
r_showtextures	Takes values in the range from 1 to 14. Displays loaded textures grouped by specified criteria.
sv_novis	Disables PVS culling of entities on the server so that you can distinguish it from client-side culling.
r_novis	Disables PVS culling of entities on the client. This normally affects only world polygons, because entities are culled on the server.
r_lockpvs	Prevents PVS refreshing so that you can see the drawing distance.
r_lightmap	Draws lightmaps without diffuse textures.
gl_wireframe	Enables edge drawing, showing how faces are split.
r_drawentities	The default value is 1. Modes 2 to 6 draw bones, hitboxes etc.
gl_renderer	The default value is 1. Setting this to 0 switches to the pure engine renderer and lets you compare the graphics.
showtriggers	Shows triggers on the map. Works only after a map restart.

Console Commands

edicts_info	Outputs brief information about edicts.
entity_info	Outputs detailed information about entities.
entpatch	Dumps a script file with entity definitions. The file can be edited manually. Subsequently, the engine loads this file instead of built-in entities.
fire	Enables activation of entities that the player is looking at or activation of the entity that is specified as an argument of the command.
impulse 103	Outputs information about the state of a monster AI.
impulse 104	Outputs information about the state of global entities (their state can be modified using env_global).
impulse 106	Outputs information about the state of regular entities (name, global name, model, parent).
impulse 107	Outputs the name of the texture that the player is looking at.
impulse 203	Removes an object from the map (except world and players, of course).
showtriggers_toggle	An alternative to the showtriggers console variable. The difference is that it shows triggers without requiring a map restart. However, most contemporary compilers (ZHLT, VHLT) perform an optimisation that deletes all triggers with the AAATRIGGER assigned and leave only the physics hull without a visible hull. To disable this behaviour, compile your map with the -nonullifytrigger command-line parameter using hlcsg. Alternatively, use a texture with a different name for triggers.
