Question by Rembo4Fight · Mar 12, 2017 at 09:28 PM · animation2dscripting problemenemyspeed

How to immediately CHANGE SPEED from spotted position to another?)

I'm creating 2d game where is the enemy moving with usual speed 2,5 and switching to speed 4 when spotted a character

What I need to change in my script to switching between 2 speed type immediately, not smooth.

Please try to help to solve this.

 using UnityEngine;
 using System.Collections;
 
 public class EnemyPatrol : MonoBehaviour {
 
     public float moveSpeed;
     public bool moveRight;
 
     public Transform sightStart, sightEnd;
 
     public bool spotted = false;
 
     public GameObject arrow;
 
     public LayerMask detectionLayers;
 
     public Transform wallCheck;
     public float wallCheckRadius;
     public LayerMask whatIsWall;
     private bool hittingWall;
 
     public Transform edgeCheck;
     public float edgeCheckRadius;
     private bool notAtEdge;
 
     public float timer = 3f; //Чтобы изменить время остановки нужно изменить кроме этого значения еще значение ниже, того же timer
 
     Animator anim;
 
     private Rigidbody2D rb2d;
 
     void Start () {
         
         rb2d = gameObject.GetComponent<Rigidbody2D>();
 
         anim = GetComponent<Animator>();
     }
 
     void FixedUpdate () {
         
         anim.SetFloat ("Speed", Mathf.Abs(rb2d.velocity.x));
 
     }
         
     void Update () {
 
         Raycasting ();
         Behaviours ();
 
         hittingWall = Physics2D.OverlapCircle (wallCheck.position, wallCheckRadius, whatIsWall);
 
         notAtEdge = Physics2D.OverlapCircle (edgeCheck.position, edgeCheckRadius, whatIsWall);
 
         if (hittingWall || !notAtEdge) {
 
             if (timer > 0) {
                 
                 timer -= Time.deltaTime;
 
                 return;
             } 
 
             moveRight = !moveRight;
 
             timer = 3f;
         }
 
         if (moveRight) 
         { 
             transform.localScale = new Vector3 (0.75f, 0.75f, 1f);
             GetComponent<Rigidbody2D>().velocity = new Vector2(moveSpeed, rb2d.velocity.y);
 
         } else {
             transform.localScale = new Vector3 (-0.75f, 0.75f, 1f);
             GetComponent<Rigidbody2D>().velocity = new Vector2(-moveSpeed, rb2d.velocity.y);
         
         }
     }
 
     void Raycasting() 
     {
         Debug.DrawLine (sightStart.position, sightEnd.position, Color.green);
         spotted = Physics2D.Linecast (sightStart.position, sightEnd.position, detectionLayers); 
     }
 
     void Behaviours() 
     {
         if (spotted == true) {
             arrow.SetActive (true);
             moveSpeed = 4;
         } else {
             arrow.SetActive (false);
             moveSpeed = 2.5;
         }
     }
 }

You should not handle rigidbody velocity on Update. It should be in FixedUdate. And anim could be in Update. Ah, and use your rb2d instead call getcomponent every frame..
