Change from Input.GetKeyDown to Input.GetTouch

Questions & Answers
1

Hello,

Super simple question.

At the moment I make my character jump using:

if (grounded && Input.GetKeyDown (KeyCode.Space)) { rigidbody2D.AddForce(new Vector2(0,jumpForce)); }

I want to change this to work on a touch screen.

I would like to make it so the character will jump when the user taps anywhere on the screen.

I’m not sure there’s a question in there but, but get touch will work for touches. I use
Input.GetMouseButtonDown(0)
This will work for mouse clicks in the editor and will also work with touches on a device. Don’t have to write separate code for touchscreen device and editor unless you are doing something more complex with the touches other than what it looks like

if(Input.GetTouch(0).phase == TouchPhase.Began)
{
//jump
}

May be helpfull

  1. create script. for example player.cs

      public class PlayerController : MonoBehaviour
 {
      bool  swipeRight = false;
      bool  swipeLeft = false;
      bool touchBlock = true;
      bool canTouchRight = true;
      bool canTouchLeft = true;

     void Update()
     {
           swipeLeft = Input.GetKeyDown("a") || Input.GetKeyDown(KeyCode.LeftArrow);
           swipeRight = Input.GetKeyDown("d") || Input.GetKeyDown(KeyCode.RightArrow);
           TouchControl();    
          if(swipeRight)  //rightMove logic
          else if(swipeLeft) //leftMove logic
    }

   void TouchControl()
   {
         if(Input.touchCount  == 1 && Input.GetTouch(0).phase == TouchPhase.Began )
        {
             //Jump logic 
         }
        else  if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved && touchBlock == true) 
       {
              touchBlock = false;
             // Get movement of the finger since last frame
             var touchDeltaPosition = Input.GetTouch(0).deltaPosition;
             Debug.Log("touchDeltaPosition "+touchDeltaPosition);
       
             if(touchDeltaPosition.x > 0 && canTouchRight == true)
            {
                 //rightMove
                 swipeRight = true; canTouchRight = false;
                  Invoke("DisableSwipeRight",0.2f);
              }
              else  if(touchDeltaPosition.x < 0 && canTouchLeft == true)
             {
                  //leftMove
                  swipeLeft = true; canTouchLeft = false;
                  Invoke("DisableSwipeLeft",0.2f);
               }       
         } 
 }
void DisableSwipeLeft()
 {
     swipeLeft = false;
     touchBlock = true;
     canTouchLeft = true;
 }
 void DisableSwipeRight()
 {
     swipeRight = false;
     touchBlock = true;
     canTouchRight = true;
 }
 }
