How to include speed trigger creation option in this script.

I am working on a VR Roller Coaster project.
Currently, roller coaster object has a constant speed that specified in the script.
I want to make 3-speed triggers such as
• normalSpeed
• climbUpSpeed (roller coaster going up)
• dropSpeed (roller coaster going down)
So I'm planning to create 3 cubes and add these 3 speeds as a tag for each of them in the inspector.

This is the code I want to edit (constant speed)

Code (CSharp):

1. using UnityEngine;
2. using PathCreation;
3.  
4. public class Follower : MonoBehaviour {
5.     public PathCreator pathCreator;
6.     public float speed = 5;
7.     float distanceTravelled;
8.  
9.     void Update() {
10.         distanceTravelled += speed * Time.deltaTime;
11.         transform.position = pathCreator.path.GetPointAtDistance(distanceTravelled);
12.         transform.rotation = pathCreator.path.GetRotationAtDistance(distanceTravelled);
13.     }
14. }

I am not so good at programming. Can someone help me out?

This is another script from a different project which has a similar function

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using BezierSolution;
5.  
6. public class SpeedController : MonoBehaviour

10.     public float dropSpeed = 20.0f;

42.      
43.

45.     }
46.  
47.     // Update is called once per frame
48.     void Update()
49.     {

The second script looks to be doing what you describe. What is your issue?

 

Hi
Thanks for replying
Yes second script is doing that perfectly.
I got these two scripts from two different projects. I got the first script from Bézier Path Creator tool (available in asset store). This tool is perfect for my use but it doesn't have speed changing feature.
Second project have speed changing but it lacks so many other major features.
So how can I get speed changing from the second script to the first ?
