Question

I am trying to make a script that lerps when a button is pressed then lerps back but its not working, heres what i have so far BTW its in c#: using UnityEngine; using System.Collections;

public class TheProperAimDownSight : MonoBehaviour { public float speed = 5.0f; public GameObject gun; Vector3 positionA = new Vector3 (0.3946627f, 0.5631797f, 0.7112392f); Vector3 positionB = new Vector3(0.009421766f, -0.1324487f, 0.5510964f);

 void Awake ()
 {
 
     
 }

void Update () { if(Input.GetMouseButton(1)) { transform.position = Vector3.Lerp(positionA, positionB, Time.deltaTime);

    }
 
    else
    {
      transform.position = Vector3.Lerp(positionB, positionA, Time.deltaTime);
      
    }
   
 }

}

It will only lerp as long as you hold the right mousebutton down. You maybe want to do it this way:

 bool lerp;
 
 void Update ()
 {
     if(Input.GetMouseButtonDown(0))
     {
         lerp = true;
     }
     if(Input.GetMouseButtonUp(0))
     {
         lerp = false;
     }
 
     if(lerp)
         transform.position = Vector3.Lerp(positionA,          positionB, Time.deltaTime);
     else
         transform.position = Vector3.Lerp(positionB, positionA, Time.deltaTime);
 }

With this code it will lerp to positionB if we clicked LMB once, if we release LMB it will lerp back to positionA.

Hope that helps in some way.

First of all please format your code the next time you paste it.

Here is the solution.

 using UnityEngine;
 using System.Collections;
  
 public class TheProperAimDownSight : MonoBehaviour 
 {   
     //Speed at w$$anonymous$$ch lerp should occur
     public float speed = 1.0f;
  
     //A and B vectors to w$$anonymous$$ch lerp should occur
     Vector3 positionA =new Vector3(0,0,0);
     Vector3 positionB=new Vector3(0,10,0);
  
     //Lerp Direction
     bool LerpedUp=false;
     //Lerp time value
     float LerpTime=1.0f;
  
     void Update()   
     { 
        //If HoldOn Right Mousebutton,Move from Point A to B  
        if(Input.GetMouseButton(1)) 
        {
          if(!LerpedUp)
          {
           //Reset LerpTime
           LerpTime=0.0f;
           //State Lerping Up(A to B)
           LerpedUp=true;
          }         
          else if(LerpTime<1.0f)
          {         
           transform.position = Vector3.Lerp(positionA , positionB,LerpTime);          
           LerpTime+=Time.deltaTime*speed;
          }
  
        }  
        else//If released Right Mousebutton,Move from Point B to A
        {
          if(LerpedUp)
          {
           //Reset LerpTime
           LerpTime=0.0f;
           //State Lerping Down(B to A)
           LerpedUp=false;
          }         
          else if(LerpTime<1.0f)
          {
             transform.position = Vector3.Lerp(positionB, positionA , LerpTime);
           LerpTime+=Time.deltaTime*speed;
          }
        } 
     } 
 }

I am trying to make a script that lerps when a button is pressed then lerps back but its not working?
