PVS (Potentially Visible Set) and PAS (Potentially Audible Set) is a set of collection of VisLeaf's, which might be visible from a given location. Thanks to them being pre-compiled by hammer, it is a very fast method of checking areas.
PVS is mostly used for render-checks, while NPC's are known to use PAS to react to sounds.
See more at:
PVS and PAS are generated from the map-file, but I've added a few helper functions to make it easier for checks and calculations for the map you're currently on. For anything more advanced, you need to use the BSPObject functions below.
| Returns | Functions | Description |
|---|---|---|
| PVS | NikNaks.PVS() | Returns the PVS from the EyePos ( CLIENT ONLY! ) |
| Boolean | NikNaks.PVS.IsPositionVisible( Vector position, Vector position2 ) | Returns true if the two positions are in same PVS. |
| PAS | NikNaks.PAS() | Returns the PAS from the EyePos ( CLIENT ONLY! ) |
| Boolean | NikNaks.PAS.IsPositionVisible( Vector position, Vector position2 ) | Returns true if the two positions are in same PAS. |
| Returns | Functions | Description |
|---|---|---|
| PVS | BSPObject:CreatePVS() | Creates an empty PVS |
| PVS | BSPObject:PVSForOrigin( Vector position, PVS?) | Creates a new or adds a position to a given PVS. |
| Boolean | BSPObject:PVSCheck( Vector position, Vector position2 ) | Returns true if the two positions is in same PVS. |
| Returns | Functions | Description |
|---|---|---|
| self | PVS:AddPVS( Vector position ) | Adds a position to a PVS. |
| self | PVS:RemovePVS( Vector position ) | Removes a position from a PVS. |
| self | PVS:RemoveLeaf( VisLeaf leaf ) | Removes a VisLeaf from a PVS. |
| Boolean | PVS:TestPosition( Vector position ) | Returns true if the position is within the PVS. |
| Table | PVS:GetLeafs() | Returns a list of all VisLeafs within the PVS. |
| Boolean | PVS:HasLeaf( VisLeaf leaf ) | Returns true if the given VisLeaf is within the PVS. |
| Returns | Functions | Description |
|---|---|---|
| PAS | BSPObject:CreatePAS() | Creates an empty PAS |
| PAS | BSPObject:PASForOrigin( Vector position, PAS?) | Creates a new or adds a position to a given PAS. |
| Boolean | BSPObject:PASCheck( Vector position, Vector position2 ) | Returns true if the two positions is in same PAS. |
| Returns | Functions | Description |
|---|---|---|
| self | PAS:AddPAS( Vector position ) | Adds a position to a PAS. |
| self | PAS:RemovePAS( Vector position ) | Removes a position from a PAS. |
| self | PAS:RemoveLeaf( VisLeaf leaf ) | Removes a VisLeaf from a PAS. |
| Boolean | PAS:TestPosition( Vector position ) | Returns true if the position is within the PAS. |
| Table | PAS:GetLeafs() | Returns a list of all VisLeafs within the PAS. |
| Boolean | PAS:HasLeaf( VisLeaf leaf ) | Returns true if the given VisLeaf is within the PAS. |
