To be precise, I have a rocket-like projectile, that is following an parabolic arc from origin to target with a Lerp. So I am looking to get the angle of an AnimationCurve at a specified evaluation time. However, if you really want to use Lerp, use something like this (C#): public float delayTime; public Vector3 posA; public Vector3 posB; void Start(){ StartCoroutine(WaitAndMove(delayTime)); } IENumerator WaitAndMove(float delayTime){ yield return new WaitForSeconds(delayTime); // start at time X Nov 11, 2020 · I’m making a 3d dragon-snake that moves from point to point in the air, turning and facing the direction it goes, but it moves in straight lines and stops too long in one spot before going onto the next. Even when I Well, one thing I notice right away is that you’re misusing Lerp in every case except line 54. . at this point i want to start moving the object but i want to catch the animation moving momentum too. Lerp works outside of Update() Questions & Answers. ) is always the start position, i. // Add it to an object in your scene, and at Play time it Nov 3, 2021 · In Unity, one can use Lerp with Vector3, Vector2, Quaternion, Mathf, Color, and Material. I just need to implement “current speed” and “remaning distance” paremeters or something else to here: float distance2 = Vector3. The movement has to be in game, meaning that I Jun 15, 2017 · Mathf. Lerping between points, regardless of Nov 3, 2021 · Using Lerp, you can get any point between positions, similar to the methods used in linear interpolation for curve fitting. In the end is to smoothly move from A to B. ina May 7, 2011, 9:03am 1. Lerp(a, b, t) returns the point midway between a and b. Animation Curves (Unity reference): they are insanely powerful for Feb 9, 2018 · I want to know if there are ease functions in Dotween where you can pass a float x and return y of that. To(myFloat, myFloat, targetVal, duration). The issue is, I have it Lerp, it works fine if the branches are rotating counter-clockwise, but if it’s rotated clockwise, it will rotate clockwise to correct it’s rotation, it doesn’t rotate counter-clockwise. I wonder though, if .
