Cos[edit]
DebugBreak[edit]
Script-induced breakpoint. Useful for examining state with the debugger at a particular point in script.
Parameters:

Interpolates with both ease-in and ease-out (smoothly departs A, smoothly approaches B).
Parameters:
- A - Value to interpolate from.
- B - Value to interpolate to.
- Alpha - Interpolant.
- Exp - Exponent. Higher values result in more rapid acceleration adn deceleration.

Tries to reach Target based on distance from Current position, giving a nice smooth feeling when tracking a position. (Doesn't work well when target teleports)
Parameters:

- Target - Target position
- DeltaTime - time since last tick
- InterpSpeed - Interpolation speed
Returns:
- new interpolated position
FMax[edit]

FRand[edit]
GetAngularDistance[edit]
Calculates the angular distance of vector 'Direction' to coordinate system O(AxisX,AxisY,AxisZ).
Orientation: (consider 'O' the first person view of the player, and 'Direction' a vector pointing to an enemy) - positive azimuth means enemy is on the right of crosshair. (negative means left). - positive elevation means enemy is on top of crosshair, negative means below.
Parameters:
- out_AngularDist - X = Azimuth angle (in radians) of 'Direction' vector compared to plane (AxisX,AxisZ). .Y = Elevation angle (in radians) of 'Direction' vector compared to plane (AxisX,AxisY).
- Direction - Direction of target.
- AxisX - X component of reference system.
- AxisY - Y component of reference system.
- AxisZ - Z component of reference system.
Output: true if 'Direction' is facing AxisX (Direction dot AxisX >= 0.f)
GetAngularFromDotDist[edit]
Converts Dot distance to angular distance.
Parameters:
- OutAngDist - Angular distance in radians.
- DotDist - Dot distance.
See: GetAngularDistance() and GetDotDistance().
GetAxes[edit]
GetDotDistance[edit]
Calculates the dotted distance of vector 'Direction' to coordinate system O(AxisX,AxisY,AxisZ).
Orientation: (consider 'O' the first person view of the player, and 'Direction' a vector pointing to an enemy) - positive azimuth means enemy is on the right of crosshair. (negative means left). - positive elevation means enemy is on top of crosshair, negative means below.
Parameters:
- OutDotDist - X = 'Direction' dot AxisX relative to plane (AxisX,AxisZ). (== Cos(Azimuth)) .Y = 'Direction' dot AxisX relative to plane (AxisX,AxisY). (== Sin(Elevation))
- Direction - direction of target.
- AxisX - X component of reference system.
- AxisY - Y component of reference system.
- AxisZ - Z component of reference system.
Returns:
- true if 'Direction' is facing AxisX (Direction dot AxisX >= 0.f)
Note: Azimuth' (.X) sign is changed to represent left/right and not front/behind. front/behind is the funtion's return value.
GetEnum[edit]
GetFuncName[edit]
Returns the current calling function's name, useful for debugging.
GetMappedRangeValue[edit]
Useful for mapping a value in one value range to a different value range. Output is clamped to the OutputRange. e.g. given that velocities [50..100] correspond to a sound volume of [0.2..1.4], find the
volume for a velocity of 77.
GetPerObjectConfigSections[edit]
Retrieve the names of sections which contain data for the specified PerObjectConfig class.
Parameters:
- SearchClass - the PerObjectConfig class to retrieve sections for.
- out_SectionNames - will receive the list of section names that correspond to PerObjectConfig sections of the specified class
- ObjectOuter - the Outer to use for determining which file to look in. Specify the same object that is used when creating the PerObjectConfig objects that sections are being retrieved for. (PerObjectConfig data is generally stored in a file named after the Outer used when creating those objects, unless the PerObjectConfig class specifies a config file in its class declaration); specify None to use the transient package as the Outer.
- MaxResults - the maximum number of section names to retrieve
Returns:
- TRUE if the file specified was found and it contained at least 1 section for the specified class

Parameters:
- Msg - the string to print to the log
- bCondition - if specified, the message is only printed to the log if this condition is satisfied.
