Mirror Engine API / math / lerpAngle

Function: lerpAngle()

function lerpAngle(a: number, b: number, alpha: number): number

Calculates the linear interpolation of two angles ensuring that interpolation is correctly performed across the 360 to 0 degree boundary. Angles are supplied in degrees.

Parameters

a

number

Angle (in degrees) to linearly interpolate from.

b

number

Angle (in degrees) to linearly interpolate to.

alpha

number

The value controlling the result of interpolation. When alpha is 0, a is returned. When alpha is 1, b is returned. Between 0 and 1, a linear interpolation between a and b is returned. alpha is clamped between 0 and 1.

Returns

number

The linear interpolation of two angles.
