Questions tagged [lerp]

Lerp is a function which Interpolates between two values in a specific time `t` to create smooth animations.

Linearly interpolates between two vectors.

Interpolates between a and b by t. t is clamped between 0 and 1. It is used to create smooth changes of all type of ui controls. Changing the Audio, a Color or transform values of an game object in unity3d can be done with Lerp easily.

How to double the lenght of a 2D array in C#

I have an array test {1, 2, 4} and want to pass it in a function IncreaseResolution(float[,] origin) which should increase the length of the array. So basically I want to turn test {1, 2, 4} into test {1, 1.5, 2, 3, 4}. So what I want to do is take…

Smooth 2d rotation in unity

I'm trying to get an object to rotate smoothly on the z axis when it comes into contact with a collider. However it just seems to snap really quickly and I can't find a way to smooth this out. I've split the rotation out into 2 scenarios - one for…

Vector3.Lerp won't move my object despite my debugging saying it should

So this is for an aim-down sight motion in a FPS game. When the player right clicks, this coroutine is fired up which should move the player's right hand from its "idle" position to its "aiming" position. Once the aiming position is reached, hitbox…

+++ EDIT +++ I have a grid of individual rectangles. Now I want to move each of the individual rectangles with the Lerp Function to a new position (currently MouseX, MouseY). So far I only manage to lerp the grid as a whole – with an unwanted…

How do I smoothly clamp controller input?

I'm trying to rotate an object according to the stick input on a controller, and then clamp it at a maximum rotation. When I use Mathf.Clamp() the rotation just hits that wall, and it doesn't feel good. I've tried using Mathf.SmoothDamp() as well…

How to use easing inside a coroutine to change a float value?

I would like to increase the value of a float over time but with added In-Out easing. Here I'm using Mathf.Lerp and I know there is Mathf.Smoothstep but in SmoothStep, I can't seem to control the speed of the easing itself. I would like the easing…

Move an object to another object with Lerp if the distance between them becomes too far in Unity

I want to move a cube A to another cube B using Lerp, but only if the distance between them is greater than 2.0f. But since Lerp is applied in multiple Update() frames, in the next Update() the distance between the two cubes is 1.9 for example, and…

Lerp not smooth when velocity changes abruptly

I have a object that moves at a variable speed. It can reach from 0 speed units up to N speed units. I'm lerping the camera angle to rotate and look at the object smoothly and nice, like this: camera.eulerAngles = Vector3.Lerp(initialAngle,…

interpolate a given array to be in new lenght

in order to interpolate 2 values, I can use lerp(int a, int b) { return (a + b) / 2; } Now imagine I've an array(1, 30, 100, 300) and I want to interpolate it to array in size N (N=10 for example). If N == 7, then: 1,15,30,65,100,200,300 I've…
