Same as Mathf.Lerp but makes sure the values interpolate correctly when they wrap around 360 degrees.

public static float LerpAngle(float a, float b, float t)

Parameters

a

float
The start angle. A float expressed in degrees.

b

float
The end angle. A float expressed in degrees.

t

float
The interpolation value between the start and end angles. This value is clamped to the range [0, 1].

Returns

Type

Description

floatReturns the interpolated float result between angle 
a
and angle 
b
, based on the interpolation value 
t
.

Remarks

This method returns the shortest path between the specified angles. This method wraps around values that are outside the range [-180, 180]. For example, LerpAngle(1.0f, 190.0f, 1.0f) returns -170.0f. To find the longest path use Mathf.Lerp.
using UnityEngine;public class Example : MonoBehaviour{    float minAngle = 0.0f;    float maxAngle = 90.0f;    void Update()    {        float angle = Mathf.LerpAngle(minAngle, maxAngle, Time.time);        transform.eulerAngles = new Vector3(0, angle, 0);    }}
