public static function Lerp(a: float, b: float, t: float): float;
public static float Lerp(float a, float b, float t);

Parameters

a The start value.
b The end value.
t The interpolation value between the two floats.

Returns

float The interpolated float result between the two float values.

Description

Linearly interpolates between a and b by t.

The parameter t is clamped to the range [0, 1].

When t = 0 returns a.
When t = 1 return b.
When t = 0.5 returns the midpoint of a and b.
