Touch buttons for step movememt

I tried the movement with lerp . Here is a bit of code

if(hit.collider.tag=="up") { Vector3 move = new Vector3 (player.transform.position.x,player.transform.position.y+4,0);

                     player.transform.position=Vector3.Lerp(player.transform.position,move,0.3f);
                     Debug.Log("up");
                 }

In above code 0.3f is the percentage of distance it should move every frame but in the present situation it is only moving 30percent of total distance not the complete distance . I think the update is checking the condition of touch began every frame that.s why it is not moving total distance.

Any solution for this?

You misunderstand the meaning of lerp, 0.3 means you just walk through 30% from starting point to the end point. You must use 1 for the whole path.

This code is working as I wanted .

using UnityEngine; using System.Collections;

public class touchcontrol : MonoBehaviour { public GameObject player; public float playerspeed=0.1f; Vector3 moven; bool ismoving=false;

 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
  if (Input.touchCount > 0) {
         if(Input.GetTouch(0).phase==TouchPhase.Began )
         {
             RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position), -Vector2.up);
             

             
             if (hit.collider != null)
             {
                 
                 if(hit.collider.tag=="up")
                 {
                     moven = new Vector3 (player.transform.position.x,player.transform.position.y+4,0);
                     ismoving = true;
                 }
                 if(hit.collider.tag=="down")
                 {
                     moven = new Vector3 (player.transform.position.x,player.transform.position.y-4,0);
                     ismoving =true;
                 }
                 if(hit.collider.tag=="right")
                 {   
                     
                      moven = new Vector3 (player.transform.position.x+1,player.transform.position.y,0);
                     ismoving = true;
                 }
                 if(hit.collider.tag=="left")
                 {
                     moven = new Vector3 (player.transform.position.x-1,player.transform.position.y,0);
                     ismoving = true;
                 }
             }




         }
     
     
     
     
     } 
     if (ismoving == true) {
         moveplayer ();
     }
 }

 void moveplayer(){
 
     player.transform.position = Vector3.MoveTowards (player.transform.position,moven,playerspeed*Time.deltaTime);
     //player.transform.position=Vector3.Lerp(player.transform.position,moven,speed);
     if (player.transform.position == moven)
         ismoving = false;
 
 
 }
