How to set movement along a Bezier curve at application start?

Question

C++ / C#

I'm trying to write in Unity.
Built a Bezier curve from 4 points
using these two scripts

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public static class Bezier
{

    public static Vector3 GetPoint(Vector3 p0, Vector3 p1, Vector3 p2, Vector3 p3, float t) {
        t = Mathf.Clamp01(t);
        float oneMinusT = 1f - t;
        return
            oneMinusT * oneMinusT * oneMinusT * p0 +
            3f * oneMinusT * oneMinusT * t * p1 +
            3f * oneMinusT * t * t * p2 +
            t * t * t * p3;
    }

    public static Vector3 GetFirstDerivative(Vector3 p0, Vector3 p1, Vector3 p2, Vector3 p3, float t) {
        t = Mathf.Clamp01(t);
        float oneMinusT = 1f - t;
        return
            3f * oneMinusT * oneMinusT * (p1 - p0) +
            6f * oneMinusT * t * (p2 - p1) +
            3f * t * t * (p3 - p2);
    }


}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[ExecuteAlways]
public class BezierTest : MonoBehaviour
{

    public Transform P0;
    public Transform P1;
    public Transform P2;
    public Transform P3;

    [Range(0,1)]
    public float t;

    void Update()
    {
        transform.position = Bezier.GetPoint(P0.position, P1.position, P2.position, P3.position, t);
        transform.rotation = Quaternion.LookRotation(Bezier.GetFirstDerivative(P0.position, P1.position, P2.position, P3.position, t));
    }


    private void OnDrawGizmos() {

        int sigmentsNumber = 20;
        Vector3 preveousePoint = P0.position;

        for (int i = 0; i < sigmentsNumber + 1; i++) {
            float paremeter = (float)i / sigmentsNumber;
            Vector3 point = Bezier.GetPoint(P0.position, P1.position, P2.position, P3.position, paremeter);
            Gizmos.DrawLine(preveousePoint, point);
            preveousePoint = point;
        }

    }

}

How to set the movement along this trajectory at the start of the project?

Answer 1

Use the free plugin from the store - Bézier Path Creator . It already has built-in construction, and finding any position on the curve, and other useful features.

Answer 2

You have already asked such a crazy question, and even chose the answer.
There is a list of bots - analyze the User Agent, but if the search engines notice (more precisely, not if, but when - most likely right away) - you will receive personal sanctions for the site.

Answer 3

throw PR out of your head, there is none and it has never been
more accurate, you will never affect the one that is, by definition
