2d dragging objects unity code example
Example 1: how to get 2D object drag with mouse unity
private Vector3 screenPoint;
private Vector3 offset;
void OnMouseDown() {
offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
}
void OnMouseDrag()
{
Vector3 curScreenPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
Vector3 curPosition = Camera.main.ScreenToWorldPoint(curScreenPoint) + offset;
transform.position = curPosition;
}
}
Example 2: drag object unity 2d
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DragAndDrop : MonoBehaviour
{
private bool isDragging;
public void OnMouseDown()
{
isDragging = true;
}
public void OnMouseUp()
{
isDragging = false;
}
void Update()
{
if (isDragging) {
Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
transform.Translate(mousePosition);
}
}
}
