What is LERP
What is LERP
In games, "lerp" (linear interpolation) is a function that smoothly blends or transitions between two values over time, such as moving a character between positions, changing an object's colour, or animating a UI element. It works by calculating a value along a straight line between a start and an end value, based on a third parameter that represents the progress of the interpolation.
