Question by netkingZ · Jun 17, 2014 at 04:41 AM · slip

How to have player “slide” on pipes and rails?

Hello , i need to create a skid or slips effect. I want create the skid or slips effect as in sunset overdrive : http://www.goodgamebro.com/omega/wp-content/uploads/2014/06/sunset-overdrive-e3-rollercoaster-1.jpg , when the main character slips on the electrical cables and on the rails. how can I create the same result? in C#. See this video: https://www.youtube.com/watch?v=zXjNkoQQPls (from 1.20 min to 1.25) . I have create this code: -OnTrigger- (apply to electric cables)

 using UnityEngine;
 using System.Collections;
 
 public class OnTriggerEnterScroll : MonoBehaviour {
 
     /*ISTRUZIONI : Inserire questo Script all'interno dell'Elemento che entra in contatto con il Trigger */
 
     public Transform target; // Player
     AutoMove AutoMoveScript; // richiamo variabili Script AutoMove
 
     // Use this for initialization
     void Start () {
         AutoMoveScript =  target.GetComponent<AutoMove>(); // Richiano componente AutoMove
     }
     
     // Update is called once per frame
     void Update () {
         Vector3 targetDir = target.position - transform.position;
         Debug.Log(targetDir);
     }
 
     void OnTriggerEnter(Collider other) { // Quando il player entra nel Trigger
         if(other.collider.name == "MainCharacter"){
         
                 AutoMoveScript.MoveSpeed = 8;  // Cambio variabile di Velocita'
                 AutoMoveScript.activeAutoMoveW = true; // Cambio variabile di scorrimento
                 AutoMoveScript.activeAutoMoveS = false; // Cambio variabile di scorrimento
 
 
         }
 
     }
 
     void OnTriggerStay(Collider other) { // Quando il player e' nel Trigger
         if(other.collider.name == "MainCharacter"){
             if(Input.GetKey(KeyCode.W)){
 
                 AutoMoveScript.activeAutoMoveW = true; // Cambio variabile di scorrimento
                 AutoMoveScript.activeAutoMoveS = false; // Cambio variabile di scorrimento
                 
             }
 
             if(Input.GetKey(KeyCode.S)){
 
                 AutoMoveScript.activeAutoMoveS = true; // Cambio variabile di scorrimento
                 AutoMoveScript.activeAutoMoveW = false; // Cambio variabile di scorrimento
                 
             }
             
         }
         
     }
     
     void OnTriggerExit(Collider other) { // Quando il player esce nel Trigger
 
         if(other.collider.name == "MainCharacter"){
                 
                 AutoMoveScript.MoveSpeed = 8; // Cambio variabile di Velocita'
                 AutoMoveScript.activeAutoMoveS = false; // Cambio variabile di scorrimento
                 AutoMoveScript.activeAutoMoveW = false; // Cambio variabile di scorrimento
         
         }
         
     }
 
 
 }

-AutoMove- (apply on main Character)

 using UnityEngine;
 using System.Collections;
 
 public class AutoMove : MonoBehaviour {
 
     /*ISTRUZIONI : Inserire questo Script all'interno del Player */
 
     public bool activeAutoMoveW = false; //variabile controllo Forward
     public bool activeAutoMoveS = false; //variabile controllo Back
 
     public int MoveSpeed = 8;    //variabile velocità di scorrimento
     public bool activeSelect = false; //variabile controllo Select
 
 
     // Use this for initialization
     void Start () {
     
 
     }
     
     // Update is called once per frame
     void Update () {
 
         if(activeAutoMoveW == true)
         {
             transform.Translate(Vector3.forward * MoveSpeed * Time.fixedDeltaTime, Space.World); // Scorrimento in avari
         }
 
         if(activeAutoMoveS == true)
         {
             transform.Translate(Vector3.back * MoveSpeed * Time.fixedDeltaTime, Space.World); // Scorrimento in  dietro
         }
 
         if(Input.GetKeyDown(KeyCode.Q) && activeSelect == false)
         {
             MoveSpeed = 1; // Cambio variabile di scorrimento
             activeSelect = true;  // Cambio variabile Slect
 
         }else if(Input.GetKeyDown(KeyCode.Q) && activeSelect == true)
         {
             MoveSpeed = 8; // Cambio variabile di scorrimento
             activeSelect = false; // Cambio variabile Slect
 
         }
 
     }
 
 }

The system create the slips effect but don't understand what is the direction of the character.

This is the alternative code , but doesn't work.

public class AutoMove : MonoBehaviour { public Vector3[] points; private int currentIndex = -1; ...

void Update() { if(activeAutoMoveW == true) { Vector3 direction = points[i+1]-points[i]; transform.position += direction MoveSpeed Time.fixedDeltaTime;

      if((transform.position - points[i+1]).sqrMagnitude < 0.1f)

//check if we are at the next point currentIndex++; } if(activeAutoMoveS == true) { Vector3 direction = points[i+1]-points[i]; transform.position -= direction MoveSpeed Time.fixedDeltaTime;

      if((transform.position - points[i]).sqrMagnitude < 0.1f)

//check if we are at the next point currentIndex--; }

  if(currentIndex < 0 || currentIndex > points.Length) //check

if we are at either edge of the line and then end the slip { activeAutoMoveW = false; activeAutoMoveS = false; {

  ...   }

public void BeginSlip(Vector3[] points) //called from the object when you want to begin the slip { this.points = points; //get the slip points from the object you slip on

  //find the closest point
  float minDist = float.MaxValue;
  for(int i=0; i     {
    float currentDist = (transform.position -

points[i]).sqrMagnitude; if(currentDist < minDist) { minDist = currentDist; currentIndex = i; } } } }
