 EZ_DECLARE_POD_TYPE ()
 
constexpr ezAngle ()
 Standard constructor, initializing with 0.
 
constexpr float GetDegree () const
 Returns the degree value. (Performs a conversion)
 
constexpr float GetRadian () const
 Returns the radian value. (No need for any conversion)
 
EZ_ALWAYS_INLINE void SetRadian (float fRad)
 Sets the radian value. (No need for any conversion)
 
void NormalizeRange ()
 Brings the angle into the range of 0 degree - 360 degree. More...
 
ezAngle GetNormalizedRange () const
 Returns an equivalent angle with range between 0 degree - 360 degree. More...
 
bool IsEqualSimple (ezAngle rhs, ezAngle epsilon) const
 Equality check with epsilon. Simple check without normalization. 360 degree will equal 0 degree, but 720 will not.
 
bool IsEqualNormalized (ezAngle rhs, ezAngle epsilon) const
 Equality check with epsilon that uses normalized angles. Will recognize 720 degree == 0 degree.

Detailed Description

Float wrapper struct for a safe usage and conversions of angles.

Uses radian internally. Will not automatically keep its range between 0 degree - 360 degree (0 - 2PI) but you can call NormalizeRange to do so.

Member Function Documentation

◆ AngleBetween()

constexpr EZ_FORCE_INLINE ezAngle ezAngle::AngleBetween ( ezAngle  a,
ezAngle  b 
)
staticconstexpr

Computes the smallest angle between the two given angles. The angle will always be a positive value.

Note
The two angles must be in the same range. E.g. they should be either normalized or at least the absolute angle between them should not be more than 180 degree.

◆ GetNormalizedRange()

ezAngle ezAngle::GetNormalizedRange ( ) const
inline

Returns an equivalent angle with range between 0 degree - 360 degree.

See also
NormalizeRange()

◆ NormalizeRange()

void ezAngle::NormalizeRange ( )

Brings the angle into the range of 0 degree - 360 degree.
