swipe player to up jump.

Questions & Answers
1

This is probably extremely simple but bare with me i’m new to touch inputs. I’m creating a game for android devices where when the player swipes up the character jumps. Any insight on how to achieve this?

For that I used one link code:-

void Update()
{
#if UNITY_ANDROID || UNITY_IPHONE
if (Input.touchCount > 0)
{
Touch touch = Input.touches[0];

    switch (touch.phase)
    {
        case TouchPhase.Began:
            startPos = touch.position;
            StartCoroutine(Jump());
            break;
        case TouchPhase.Moved:
            isSwipe = true;
            float swipeDistHorizontal = (new Vector3(touch.position.x, 0, 0) - new Vector3(startPos.x, 0, 0)).magnitude;
            float swipeDistVertical = (new Vector3(0, touch.position.y, 0) - new Vector3(0, startPos.y, 0)).magnitude;
            if (swipeDistHorizontal > minSwipeDistX)
            {
                float swipeValue = Mathf.Sign(touch.position.x - startPos.x);
                if (swipeValue > 0 && !isTouch)//to right swipe
                {
                    isTouch = true;
                    StartCoroutine(Right());
                }
                else if (swipeValue < 0 && !isTouch)//to left swipe
                {
                    isTouch = true;
                    StartCoroutine(Left());
                }
            }

            //add swipe to up
            if(swipeDistVertical > minSwipeDistY)
            {
                float swipeValue = Mathf.Sign(touch.position.y - startPos.y);
                if(swipeValue > 0 && !isTouch)
                {
                    isTouch = true;
                    StartCoroutine(Jump2());
                }
            }
            break;
        case TouchPhase.Ended:
            isSwipe = false;
            isTouch = false;
            break;
    }
}
#endif

}
IEnumerator Jump2()
{
yield return new WaitForSeconds(0.05f);
if(playerVelocity <= 0.2f)
{
Debug.Log(“Swipe Up”);
}
}

IEnumerator Jump()
{
if (!isSwipe)
{
yield return new WaitForSeconds(0.05f);
if (!isSwipe && playerVelocity <= 0.2f)
{
Debug.Log(“Tap”);

    }
    else
    {
        yield break;
    }
}
else
{
    yield break;
}

}

IEnumerator Right()
{
Debug.Log(“Right”);

}

IEnumerator Left()
{
Debug.Log(“Left”);

}

Here is how I did it, but using Character Controller

If you are using real life physics, this is not very useful.

private Vector3 moveDirection = Vector3.zero;
private CharacterController cc;
public float gravity = 9.81f;

void Update() {

if (Input.touches.Length > 0)
            {
                Touch t = Input.GetTouch(0);
                if (t.phase == TouchPhase.Began)
                {
                    //save began touch 2d point
                    firstPressPos = new Vector2(t.position.x, t.position.y);
                }
                if (t.phase == TouchPhase.Ended)
                    {
                    //save ended touch 2d point
                    secondPressPos = new Vector2(t.position.x, t.position.y);
    
                    //create vector from the two points
                    currentSwipe = new Vector2(secondPressPos.x - firstPressPos.x, secondPressPos.y - firstPressPos.y);
    
                    //normalize the 2d vector
                    currentSwipe.Normalize();
    
                    //swipe up
                    if (currentSwipe.y > 0 && currentSwipe.x > -0.5f && currentSwipe.x < 0.5f && _characterController.isGrounded)
                    {
                        moveDirection.y = jumpSpeed;
                        
                    }

        //make the character fall each update
        moveDirection.y -= gravity * Time.deltaTime;
        moveDirection.z = zVelocity;
        _characterController.Move(moveDirection * Time.deltaTime);

}

I hope it leads you somewhere safer :stuck_out_tongue:
