MASK_SOLID	everything that is normally solid
MASK_SOLID_BRUSHONLY	everything normally solid, except monsters (world+brush only)
MASK_SPLITAREAPORTAL	These are things that can split areaportals
MASK_VISIBLE	everything that blocks line of sight for players
MASK_VISIBLE_AND_NPCS	everything that blocks line of sight for players, but with monsters added.
MASK_WATER	water physics in these contents
PARTITION_NON_STATIC_EDICTS	everything in solid & trigger except the static props, includes SOLID_NOTs
PARTITION_SOLID_EDICTS	every edict_t that isn't SOLID_TRIGGER or SOLID_NOT (and static props)
PARTITION_STATIC_PROPS
PARTITION_TRIGGER_EDICTS	every edict_t that IS SOLID_TRIGGER
SURF_BUMPLIGHT	calculate three lightmaps for the surface for bumpmapping
SURF_HINT	make a primary bsp splitter
SURF_HITBOX	surface is part of a hitbox
SURF_LIGHT	value will hold the light strength
SURF_NOCHOP	Don't subdivide patches on this surface
SURF_NODECALS	Don't receive decals
SURF_NODRAW	don't bother referencing the texture
SURF_NOLIGHT	Don't calculate light
SURF_NOPORTAL	the surface can not have a portal placed on it
SURF_NOSHADOWS	Don't receive shadows
SURF_SKIP	completely ignore, allowing non-closed brushes
SURF_SKY	don't draw, but add to skybox
SURF_SKY2D	don't draw, indicates we should skylight + draw 2d sky but not draw the 3D skybox
SURF_TRANS
SURF_TRIGGER	This is an xbox hack to work around elimination of trigger surfaces, which breaks occluders
SURF_WARP	turbulent water warp

Functions38

Symbol	Description
TR_AllSolid	Returns whether the entire trace was in a solid area.
TR_ClipCurrentRayToEntity	Clips the current global ray (or hull) to a particular entity.
TR_ClipCurrentRayToEntityEx	Clips the current global ray (or hull) to a particular entity.
TR_ClipRayHullToEntity	Clips a ray hull to a particular entity.
TR_ClipRayHullToEntityEx	Clips a ray hull to a particular entity.
TR_ClipRayToEntity	Clips a ray to a particular entity.
TR_ClipRayToEntityEx	Clips a ray to a particular entity.
TR_DidHit	Returns if there was any kind of collision along the trace ray.
TR_EnumerateEntities	Enumerates over entities along a ray. This may find entities that are close to the ray but do not actually intersect it. Use TR_Clip*RayToEntity with TR_DidHit to check if the ray actually intersects the entity.
TR_EnumerateEntitiesBox	Enumerates over entities in a box.
TR_EnumerateEntitiesHull	Enumerates over entities along a ray hull. This may find entities that are close to the ray but do not actually intersect it. Use TR_Clip*RayToEntity with TR_DidHit to check if the ray actually intersects the entity.
TR_EnumerateEntitiesPoint	Enumerates over entities at point.
TR_EnumerateEntitiesSphere	Enumerates over entities in a sphere.
TR_GetDisplacementFlags	Returns the displacement flags for the surface that was hit. See DISPSURF_FLAG_*.
TR_GetEndPosition	Returns the collision position of a trace result.
TR_GetEntityIndex	Returns the entity index that collided with the trace.
TR_GetFraction	Returns the time fraction from a trace result (1.0 means no collision).
TR_GetFractionLeftSolid	Returns the time fraction from a trace result when it left a solid. Only valid if trace started in solid
TR_GetHitBoxIndex	Returns in which hitbox the trace collided if any. Note: if the entity that collided with the trace is the world entity, then this function doesn't return an hitbox index but a static prop index.
TR_GetHitGroup	Returns in which body hit group the trace collided if any.
TR_GetPhysicsBone	Returns the index of the physics bone that was hit.
TR_GetPlaneNormal	Find the normal vector to the collision plane of a trace.
TR_GetPointContents	Get the contents mask and the entity index at the given position.
TR_GetPointContentsEnt	Get the point contents testing only the given entity index.
TR_GetStartPosition	Returns the starting position of a trace.
TR_GetSurfaceFlags	Returns the surface flags. See SURF_*.
TR_GetSurfaceName	Returns the name of the surface that was hit.
TR_GetSurfaceProps	Returns the surface properties index of the surface that was hit.
TR_PointOutsideWorld	Tests a point to see if it's outside any playable area
TR_StartSolid	Returns whether the initial point was in a solid area.
TR_TraceHull	Starts up a new trace hull using a global trace result.
TR_TraceHullEx	Starts up a new trace hull using a new trace result.
TR_TraceHullFilter	Starts up a new trace hull using a global trace result and a customized trace ray filter. Calling TR_TraceFilter or TR_TraceFilterEx from inside a filter function is currently not allowed and may not work.
TR_TraceHullFilterEx	Starts up a new trace hull using a new trace result and a customized trace ray filter. Calling TR_TraceFilter or TR_TraceFilterEx from inside a filter function is currently not allowed and may not work.
TR_TraceRay	Starts up a new trace ray using a global trace result.
TR_TraceRayEx	Starts up a new trace ray using a new trace result.
TR_TraceRayFilter	Starts up a new trace ray using a global trace result and a customized trace ray filter. Calling TR_TraceFilter or TR_TraceFilterEx from inside a filter function is currently not allowed and may not work.
TR_TraceRayFilterEx	Starts up a new trace ray using a new trace result and a customized trace ray filter. Calling TR_TraceFilter or TR_TraceRayEx from inside a filter function is currently not allowed and may not work.
