physenv
The physenv library allows you to control the physics environment created by the engine, and lets you modify constants such as gravity and maximum velocity.
Methods
physenv.AddSurfaceData( string properties )
Adds surface properties to the game's physics environment.
The game has a limit of 128 surface properties - this includes properties loaded automatically from surfaceproperties. txt. Due to this, there's only a small amount of open slots that can be registered with GMod's provided surfaceproperties. txt. Issue Tracker: 2604
number physenv.GetAirDensity()
Returns the air density used to calculate drag on physics objects.
The unit is in kg/m³.
Vector physenv.GetGravity()
Gets the gravitational acceleration used for physics objects in source_unit/s^2.
number physenv.GetLastSimulationTime()
Returns the last simulation duration of the in-game physics.
table physenv.GetPerformanceSettings()
Gets the current performance settings in table form.
physenv.SetAirDensity( number airDensity )
Sets the air density.
physenv.SetGravity( Vector gravAccel )
Sets the gravitational acceleration used for physics objects.
Does not work on players.
physenv.SetPerformanceSettings( table performanceSettings )
Sets the performance settings.
