I am practicing in Unity; I want to move an object to the right and left according to how I swipe. I have gotten the script so far but the problem occurs when I am playing it. It is setting the objects location to the center; swipe actions are working just fine. However, I don't want it to set the object to the center.
Script:
public class swipeTest : MonoBehaviour {
public SwipeManager swipeControls;
public Transform Player;
private Vector3 desiredPosition;
private void Update() {
if (swipeControls.SwipeLeft)
desiredPosition += Vector3.left;
if (swipeControls.SwipeRight)
desiredPosition += Vector3.right;
Player.transform.position = Vector3.MoveTowards
(Player.transform.position, desiredPosition, 0.5f * Time.deltaTime);
}
}
And Another
public class SwipeManager : MonoBehaviour {
private bool tap, swipeLeft, swipeRight, swipeUp, swipeDown;
private bool isDraging = false;
private Vector2 startTouch, swipeDelta;
public Vector2 SwipeDelta { get { return swipeDelta; } }
public bool Tap { get { return tap; } }
public bool SwipeLeft { get { return swipeLeft; } }
public bool SwipeRight { get { return swipeRight; } }
public bool SwipeUp { get { return swipeUp; } }
public bool SwipeDown { get { return swipeDown; } }
private void Update() {
tap = swipeLeft = swipeRight = swipeUp = swipeDown = false;
#region Standalone Inputs
if (Input.GetMouseButtonDown(0)) {
tap = true;
isDraging = true;
startTouch = Input.mousePosition;
}
else if (Input.GetMouseButtonUp(0)) {
isDraging = false;
Reset();
}
#endregion
#region Mobile Input
if (Input.touches.Length > 0) {
if (Input.touches[0].phase == TouchPhase.Began) {
isDraging = true;
tap = true;
startTouch = Input.touches[0].position;
}
else if (Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled) {
isDraging = false;
Reset();
}
}
#endregion
// Calculate the distance
swipeDelta = Vector2.zero;
if (isDraging) {
if (Input.touches.Length > 0)
swipeDelta = Input.touches[0].position - startTouch;
else if (Input.GetMouseButton(0))
swipeDelta = (Vector2)Input.mousePosition - startTouch;
}
//Did we cross the distance?
if (swipeDelta.magnitude > 125) {
//Which direction?
float x = swipeDelta.x;
float y = swipeDelta.y;
if (Mathf.Abs(x) > Mathf.Abs(y)) {
//Left or right
if (x < 0)
swipeLeft = true;
else
swipeRight = true;
}
else {
// Up or down
if (y < 0)
swipeDown = true;
else
swipeUp = true;
}
Reset();
}
}
void Reset() {
startTouch = swipeDelta = Vector2.zero;
isDraging = false;
}
}
It seems like you never initialised desiredPosition in your code.
I did not successfully reproduce your issue, but theoretically I believe this should work. Please let us know if it helped.
Assuming no other forces act on the Player tranform (it won't be moved other than by this script):
public class swipeTest : MonoBehaviour {
private void Start() {
desiredPosition = Player.position;
}
}
Or if other forces act on Player you should update it every time:
public class swipeTest : MonoBehaviour {
private void Update() {
desiredPosition = Player.position;
if (swipeControls.SwipeLeft)
desiredPosition += Vector3.left;
if (swipeControls.SwipeRight)
desiredPosition += Vector3.right;
Player.transform.position = Vector3.MoveTowards
(Player.transform.position, desiredPosition, 0.5f * Time.deltaTime);
}
}

I am using Destroy(Corazones[0].gameObject); to destroy 5 hearts in an array, but I need to restore them when the player gets another heart. I already have the collider that increases lives +1 and it works, but I do not know how to respawn the heart that represents that life.
The hearts get destroyed when the player gets Hit(); but I also need for the hearts to get restored with Vida(); which increases the live +1
Thanks for your help!
This is the way the hearts look
My code uses spanish words.
PD: I know my code is a mess, but works for the other stuff.

Instead of using Destroy(Corazones[0].gameObject) you could use Corazones[0].gameObject.setActive(false) or simply Corazones[0].setActive(false) since the array already contains GameObjects.
This would preserve the GameObject while all of its components and children would be inactivated including its Renderer which would make it disappear.
Then later when you need it you could reactivate it using Corazones[0].setActive(true).
I have a Unity project that I started a couple of days ago. It is a simple 2D top down shooting game, which is aimed to be played on smartphone platforms.
I have a Shooting script, which basically has a method called Shoot1, which spawns in a bullet.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Shooting : MonoBehaviour
{
public Transform firePoint;
public GameObject BulletRedPrefab;
public GameObject BulletGreenPrefab;
public float bulletForce = 20f;
// Update is called once per frame
void Start()
{
}
void Update()
{
}
public IEnumerator Shoot1()
{
yield return new WaitForSeconds(0.00001f);
GameObject bullet = Instantiate(BulletRedPrefab, firePoint.position, firePoint.rotation);
Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);
}
}
I also have the Swipe script which determines the direction of the swipe, etc.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Swipe : MonoBehaviour
{
private bool tap, swipeUp, swipeDown, swipeLeft, swipeRight;
private bool isDraging = false;
private Vector2 startTouch, swipeDelta;
// Update is called once per frame
private void Update()
{
tap = swipeUp = swipeDown = swipeLeft = swipeRight = false;
if (Input.touches.Length > 0)
{
if (Input.touches[0].phase == TouchPhase.Began)
{
isDraging = true;
tap = true;
startTouch = Input.touches[0].position;
}
else if (Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
{
isDraging = false;
Reset();
}
}
if (Input.GetMouseButtonDown(0))
{
tap = true;
isDraging = true;
startTouch = Input.mousePosition;
}
else if (Input.GetMouseButtonUp(0))
{
isDraging = false;
Reset();
}
swipeDelta = Vector2.zero;
if (isDraging)
{
if (Input.touches.Length > 0)
swipeDelta = Input.touches[0].position - startTouch;
else if (Input.GetMouseButton(0))
swipeDelta = (Vector2)Input.mousePosition - startTouch;
}
if (swipeDelta.magnitude > 125)
{
float x = swipeDelta.x;
float y = swipeDelta.y;
if (Mathf.Abs(x) > Mathf.Abs(y))
{
if (x < 0)
swipeLeft = true;
else
swipeRight = true;
}
else
{
if (y < 0)
swipeDown = true;
else
swipeUp = true;
}
Reset();
}
}
private void Reset()
{
startTouch = swipeDelta = Vector2.zero;
isDraging = false;
}
public Vector2 SwipeDelta { get { return swipeDelta; } }
public bool SwipeUp { get { return swipeUp; } }
public bool SwipeDown { get { return swipeDown; } }
public bool SwipeLeft { get { return swipeLeft; } }
public bool SwipeRight { get { return swipeRight; } }
}
And I have the GestureDetector script which is aimed to shoot a bullet whenever the user swipes left, right, up or down. When I tried to make the player object (which is called robot) move via swiping, it worked. But when I try calling a method from another class with swiping, it's not working.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GestrueDetector : MonoBehaviour
{
public Shooting other;
public Swipe swipeControls;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
private void Update()
{
if (GameObject.Find("robot") != null)
{
if (swipeControls.SwipeLeft)
desirePosition += Vector3.left;
other.Shoot1();
if (swipeControls.SwipeRight)
desirePosition += Vector3.right;
other.Shoot1();
if (swipeControls.SwipeUp)
desirePosition += Vector3.up;
other.Shoot1();
if (swipeControls.SwipeDown)
desirePosition += Vector3.down;
other.Shoot1();
}
}
}
I just started using unity this week, so I'm quite new to the software. Thank you very much!
For coroutines you need to call this methods like this:
StartCoroutine(Shoot1());
I a little bit changed your classes:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Shooting : MonoBehaviour
{
public Transform firePoint;
public GameObject BulletRedPrefab;
public GameObject BulletGreenPrefab;
public float bulletForce = 20f;
void Start ()
{
}
void Update()
{
}
public void Shoot()
{
StartCoroutine(Shoot1());
}
private IEnumerator Shoot1()
{
yield return new WaitForSeconds(0.00001f);
GameObject bullet = Instantiate(BulletRedPrefab, firePoint.position, firePoint.rotation);
Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);
}
}
And for GestrueDetector:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GestrueDetector : MonoBehaviour
{
public Shooting other;
public Swipe swipeControls;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
private void Update()
{
if (GameObject.Find("robot") != null)
{
if (swipeControls.SwipeLeft)
desirePosition += Vector3.left;
other.Shoot();
if (swipeControls.SwipeRight)
desirePosition += Vector3.right;
other.Shoot();
if (swipeControls.SwipeUp)
desirePosition += Vector3.up;
other.Shoot();
if (swipeControls.SwipeDown)
desirePosition += Vector3.down;
other.Shoot();
}
}
}
Just read more about how coroutines are working in Unity - https://docs.unity3d.com/ScriptReference/Coroutine.html
My game is an endless runner and the character only needs to move along the y-axis. What I want to happen is that the player moves up or down depending on the swipe, and I thought that I could do it by stating that if the player triggered the onSwipeUp or down then they would move in that direction, but I couldn't get it working.
This is the player controller script before I tried implementing swipe controls into it:
public class Player : MonoBehaviour
{
private Vector2 targetPos;
public float yIncrement;
public float maxHeight;
public float minHeight;
private void Update()
{
transform.position = Vector2.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
if (Input.GetKeyDown(KeyCode.W) && transform.position.y < maxHeight)
{
Instantiate(effect, transform.position, Quaternion.identity);
targetPos = new Vector2(transform.position.x, transform.position.y + yIncrement);
}
else if (Input.GetKeyDown(KeyCode.S) && transform.position.y > minHeight)
{
Instantiate(effect, transform.position, Quaternion.identity);
targetPos = new Vector2(transform.position.x, transform.position.y - yIncrement);
}
}
And this is the swipe detecting script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class SwipeTest : MonoBehaviour
{
private Vector2 fingerDown;
private Vector2 fingerUp;
public bool detectSwipeOnlyAfterRelease = false;
public float SWIPE_THRESHOLD = 20f;
// Update is called once per frame
void Update()
{
foreach (Touch touch in Input.touches)
{
if (touch.phase == TouchPhase.Began)
{
fingerUp = touch.position;
fingerDown = touch.position;
}
//Detects Swipe while finger is still moving
if (touch.phase == TouchPhase.Moved)
{
if (!detectSwipeOnlyAfterRelease)
{
fingerDown = touch.position;
checkSwipe();
}
}
//Detects swipe after finger is released
if (touch.phase == TouchPhase.Ended)
{
fingerDown = touch.position;
checkSwipe();
}
}
}
void checkSwipe()
{
//Check if Vertical swipe
if (verticalMove() > SWIPE_THRESHOLD && verticalMove() > horizontalValMove())
{
//Debug.Log("Vertical");
if (fingerDown.y - fingerUp.y > 0)//up swipe
{
OnSwipeUp();
}
else if (fingerDown.y - fingerUp.y < 0)//Down swipe
{
OnSwipeDown();
}
fingerUp = fingerDown;
}
//Check if Horizontal swipe
else if (horizontalValMove() > SWIPE_THRESHOLD && horizontalValMove() > verticalMove())
{
//Debug.Log("Horizontal");
if (fingerDown.x - fingerUp.x > 0)//Right swipe
{
OnSwipeRight();
}
else if (fingerDown.x - fingerUp.x < 0)//Left swipe
{
OnSwipeLeft();
}
fingerUp = fingerDown;
}
//No Movement at-all
else
{
//Debug.Log("No Swipe!");
}
}
float verticalMove()
{
return Mathf.Abs(fingerDown.y - fingerUp.y);
}
float horizontalValMove()
{
return Mathf.Abs(fingerDown.x - fingerUp.x);
}
//////////////////////////////////CALLBACK FUNCTIONS/////////////////////////////
public void OnSwipeUp()

You could set a public boolean for each swipe direction. In the first lines of update set these booleans to false, in the onswipe functions set the respective booleans to true. Then reference the swipetest script from the player script and check if the desired swipe boolean is set to true.
The code would look something like this:
player:
public class Player : MonoBehaviour
{
private Vector2 targetPos;
public float yIncrement;
public float maxHeight;
public float minHeight;
public SwipeTest swipetest;
private void OnEnable()
{
swipetest = (SwipeTest)FindObjectOfType(typeof(SwipeTest));
}
private void Update()
{
transform.position = Vector2.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
if (swipetest.swipeUp && transform.position.y < maxHeight)
{
Instantiate(effect, transform.position, Quaternion.identity);
targetPos = new Vector2(transform.position.x, transform.position.y + yIncrement);
}
else if (swipetest.swipeDown && transform.position.y > minHeight)
{
Instantiate(effect, transform.position, Quaternion.identity);
targetPos = new Vector2(transform.position.x, transform.position.y - yIncrement);
}

I'm developing a mobile android game in Unity, and I have a menu panel that slides in from the right, using animation, when a button is clicked. Now I want to trigger the button to be clicked when the player swipes left. Basically I want to "click the menu button" when I swipe left on the screen without actually touching the button. This way it would trigger the animation and all other function of the button. Is it possible to achieve that? This is my script for the swipe detection:
//Swipe
private bool tap, swipeLeft, swipeRight, swipeUp, swipeDown;
private bool isDraging = false;
private Vector2 startTouch, swipeDelta;
private void Update()
{
tap = swipeLeft = swipeRight = swipeUp = swipeDown = false;
if (Input.touches.Length > 0)
{
if (Input.touches[0].phase == TouchPhase.Began)
{
isDraging = true;
tap = true;
startTouch = Input.touches[0].position;
}
else if (Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
{
isDraging = false;
Reset();
}
}
//Calculate Distance
swipeDelta = Vector2.zero;
if (isDraging)
{
if (Input.touches.Length > 0)
{
swipeDelta = Input.touches[0].position - startTouch;
}
}
if (swipeDelta.magnitude > 125)
{
float x = swipeDelta.x;
float y = swipeDelta.y;
if (Mathf.Abs(x) > Mathf.Abs(y))
{
//Left Or Right
if (x < 0)
{
swipeLeft = true;
}
else
{
swipeRight = true;
}
}
else
{
if (y < 0)
{
swipeDown = true;
}
else
{
swipeUp = true;
}
}
Reset();
}
}
private void Reset()
{
startTouch = Vector2.zero;
isDraging = false;
}
public Vector2 SwipeDelta { get { return swipeDelta; } }
public bool SwipeLeft { get { return swipeLeft; } }
public bool SwipeRight { get { return swipeRight; } }
public bool SwipeUp { get { return swipeUp; } }
public bool SwipeDown { get { return swipeDown; } }
How can I achieve my idea and how to implement it to my game?
