Drag GameObject with finger touch in SmartPhone
I have maybe a dumb question, but how do I drag a GameObject when I touch the screen? i'm new in Unity and i need to drag an object and make collide against other object.
You need to check for touches, get the touch and update the transform of whatever object you're touching(hopefully).
Documentation of concern:
if (Input.touchCount > 0)
{
Touch touch = Input.GetTouch(0); // get first touch since touch count is greater than zero
if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved)
{
// get the touch position from the screen touch to world point
Vector3 touchedPos = Camera.main.ScreenToWorldPoint(new Vector3(touch.position.x, touch.position.y, 10));
// lerp and set the position of the current object to that of the touch, but smoothly over time.
transform.position = Vector3.Lerp(transform.position, touchedPos, Time.deltaTime);
}
}
thanks a lot. I used the next code and kind of work for me but the problem that i got is that i use the same code for several sprites but when I pass over another sprite the sprite absorb the other one. how can i fix that?
using UnityEngine; using System.Collections;
public class movimiento : $$anonymous$$onoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update ()
{
//Gets the world position of the mouse on the screen
Vector2 mousePosition = Camera.main.ScreenToWorldPoint( Input.mousePosition );
//Checks whether the mouse is over the sprite
bool overSprite = this.GetComponent<SpriteRenderer>().bounds.Contains( mousePosition );
//If it's over the sprite
if (overSprite)
{
//If we've pressed down on the mouse (or touched on the iphone)
if (Input.GetButton("Fire1"))
{
//Set the position to the mouse position
this.transform.position = new Vector3(Camera.main.ScreenToWorldPoint(Input.mousePosition).x,
Camera.main.ScreenToWorldPoint(Input.mousePosition).y,
0.0f);
}
}
}
}
I used this code and it works well, the only problem I have is that it moves the object along all three axis and I need it to move only on x and y. Do you maybe have a solution for that?
The code above works for the most part, however, if this is on a prefab, then it moves all of the instances simultaneously. Is there a modification to work around this issue?
Thanks!
Hey! Late to the party here but OnMouseDrag() totally works on mobile. Here is what worked for me:
void OnMouseDrag()
{
Vector3 mousePosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, distance);
Vector3 objPosition = Camera.main.ScreenToWorldPoint(mousePosition);
transform.position = objPosition;
}
For this to work, make sure you have a collider attached to your sprite.
It (On$$anonymous$$ouseDrag) works but it is not recommended on mobile devices for performance reasons.
Hi! I know it's an old post but I give it a try. I tried this drag and drop script with smartphone, and my problem is it just put the sprite in the middle of the screen, doesn't matter wheter I click with mouse or touch my smarphone screen. Anyone with the same issue? If somebody know a solution please tell me.
