# What is unity LERP?

## What is unity LERP?

What is Lerp in Unity? Lerp, or Linear Interpolation, is a mathematical function in Unity that returns a value between two others at a point on a linear scale. Most commonly it’s used for moving or changing values over a period of time.

## What does Vector3 LERP do in unity?

This is most commonly used to find a point some fraction of the way along a line between two endpoints (e.g. to move an object gradually between those points). The value returned equals a + (b – a) * t (which can also be written a * (1-t) + b*t). When t = 0, Vector3. Lerp(a, b, t) returns a .

How do I know when my LERP is finished unity?

You don’t “detect when Lerp is done”; you call Lerp repeatedly, every frame, and each time you tell it how done it is. The third parameter is a value from 0 to 1. You feed Lerp a variable that counts up to 1, and when that variable is at 1, it’s “done”.

### Does LERP only work in update?

3 Replies. It’s a plain old function, so it ‘works’ anywhere – in that it will correctly calculate a value that is the linear interpolation between the start and end values.

What is the math behind LERP?

lerp(a, b, x) = a + (b -a ) * x; From this formula you can get that the third parameter is actually just the percentage of the B. You then multiply it with B to calculate the percent value, and sum it with the percentage of A (which is equal to 100% minus the percent of B).

#### What does LERP do unreal?

Lerp is slang for Linear Interpolate. Given two different inputs A and B, think of a straight line drawn between them – with the Alpha node saying how far along that line you are. For example, lets say you have a red color [1,0,0] in A – and a blue color [0,0,1] in B.

#### What is LERP l4d2?

The Lerp describes a time value, in milliseconds which is used by the game to smooth animations between each updates.
