Game Scenes:: Flight

float getWarpFactor()¶

The current warp factor. This is the index of the rate at which time is passing for either regular “on-rails” or physical time warp. Returns 0 if time warp is not active. When in on-rails time warp, this is equal to getRailsWarpFactor(), and in physics time warp, this is equal to getPhysicsWarpFactor().

Game Scenes:: Flight

int getRailsWarpFactor()¶

void setRailsWarpFactor(int value)¶

The time warp rate, using regular “on-rails” time warp. A value between 0 and 7 inclusive. 0 means no time warp. Returns 0 if physical time warp is active.

If requested time warp factor cannot be set, it will be set to the next lowest possible value. For example, if the vessel is too close to a planet. See the KSP wiki for details.

Game Scenes:: Flight

int getPhysicsWarpFactor()¶

void setPhysicsWarpFactor(int value)¶

The physical time warp rate. A value between 0 and 3 inclusive. 0 means no time warp. Returns 0 if regular “on-rails” time warp is active.

Game Scenes:: Flight

boolean canRailsWarpAt(int factor)¶

Returns true if regular “on-rails” time warp can be used, at the specified warp factor. The maximum time warp rate is limited by various things, including how close the active vessel is to a planet. See the KSP wiki for details.

Parameters:

factor (int) – The warp factor to check.

Flight

int getMaximumRailsWarpFactor()¶

The current maximum regular “on-rails” warp factor that can be set. A value between 0 and 7 inclusive. See the KSP wiki for details.

Game Scenes:: Flight

void warpTo(double ut, float maxRailsRate, float maxPhysicsRate)¶

Uses time acceleration to warp forward to a time in the future, specified by universal time ut. This call blocks until the desired time is reached. Uses regular “on-rails” or physical time warp as appropriate. For example, physical time warp is used when the active vessel is traveling through an atmosphere. When using regular “on-rails” time warp, the warp rate is limited by maxRailsRate, and when using physical time warp, the warp rate is limited by maxPhysicsRate.

Parameters:

ut (double) – The universal time to warp to, in seconds.
maxRailsRate (float) – The maximum warp rate in regular “on-rails” time warp.
maxPhysicsRate (float) – The maximum warp rate in physical time warp.

Returns:

When the time warp is complete.
