Camera stuff is pretty tricky… you may wish to consider using Cinemachine from the Unity Package Manager. Some info on the game: It's a 2D, top-down space game, and you control a spaceship that can accelerate or rotate. t: Interpolation ratio. They use the arrow keys to controll the rolling of the ball. GetKey (KeyCode. If I didn’t multiply by Time. The parameter t is clamped to the range [0, 1]. I think one of the reasons might be related to the small values from the accelerometer data. 0f)) always evaluates to the roughly the same velocity. Or better yet, don't use Lerp at all, and instead set the object's velocity and let Unity's physics engine take care of it. It interpolates your value From to To over T. I am experimenting with a bike model and trying to learn how to use Lerp to update its velocity. velocity = vector3. Here’s my code: using UnityEngine; using System.
