static float Hydrogen.Math.ClampAngle ( float  angle,
float  minimumAngle,
float  maximumAngle 
)
static

Clamp and neutralize an angle.

Returns
The clamped and neutralized angle.
Parameters
angleThe source angle.
minimumAngleMinimum angle.
maximumAngleMaximum angle.

Definition at line 45 of file Math.cs.

46  {
47  // Clamp that angle up
48  return UnityEngine.Mathf.Clamp (NeutralizeAngle (angle), minimumAngle, maximumAngle);
49  }
Hydrogen.Math.NeutralizeAngle
static float NeutralizeAngle(float angle)
Neutralizes the an angle, providing an angle below 360 degrees.
Definition: Math.cs:56
static float Hydrogen.Math.NeutralizeAngle ( float  angle)
static

Neutralizes the an angle, providing an angle below 360 degrees.

Returns
The neutralized angle.
Parameters
angleThe source angle.

Definition at line 56 of file Math.cs.

57  {
58  // Neutralize really fucked up angles
59  if (angle < 0)
60  return (angle % 360f) * -1;
61  else
62  return angle % 360f;
63  }
static float Hydrogen.Math.SignedAngle ( float  angle)
static

The signed equivalent of the angle.

Returns
The signed angle.
Parameters
angleThe source angle.

Definition at line 70 of file Math.cs.

71  {
72  angle = angle % 360f;
73 
74  if (angle > 180f) {
75  return (180 - ((angle % 180f))) * -1f;
76  } else if (angle < -180) {
77  return ((angle % 180) * -1f);
78  }
79  return angle;
80  }
static object Hydrogen.Math.ToUnsigned ( object  value)
static

Converts the specified values boxed type to its corresponding unsigned type.

Returns
A boxed numeric object whos type is unsigned.

This allows for converting without knowing the original type.

Parameters
valueThe value.
