How to destroy a object when dragged into an empty canvas.

Questions & Answers

I am making a game which involves a lot of drag and drop. I have some objects that the player has to drag into the object slot. How do I destroy the object if the player drags it outside the slot or somewhere randomly on the canvas. This is the code I have used.
`
public class dragDrop : MonoBehaviour, IDragHandler, IBeginDragHandler, IEndDragHandler
{
Image image;
CanvasGroup canvasGroup;
Vector2 initPosition;

void Awake(){
    Time.timeScale = 1;
    image = GetComponent<Image>();
    canvasGroup = GetComponent<CanvasGroup>();
    initPosition = transform.position;
    
    
}
public void OnBeginDrag(PointerEventData eventData)
{
    canvasGroup.alpha = 0.5f;
    canvasGroup.blocksRaycasts = false;
    

}

public void OnDrag(PointerEventData eventData)
{
    transform.position = eventData.position;
   
}

public void OnEndDrag(PointerEventData eventData)
{
    canvasGroup.alpha = 1f;
    canvasGroup.blocksRaycasts = true;
   
}

}

Not sure what’s the best solution, but when i personally had this problem, i approached it like this:
Get data what’s under mouse. Use OnPointerEnter method/event for that. It should be on both ObjectSlot and Canvas Interface. I created static class to hold variable of what’s currently under my mouse.

public static class MouseData
{
    public static object objectMouseIsOver;
}

OnPointerEnter event method example:

OnPointerEnter(ObjectSlot slot)
{
     MouseData.objectMouseIsOver = slot;
}

Example of my Inventory : MonoBehavior, IPointerEnterHandler

public void OnPointerEnter(PointerEventData eventData)
	{
		MouseData.objectMouseIsOver = eventData.pointerCurrentRaycast.gameObject;
		Debug.Log(MouseData.objectMouseIsOver);
	}

Basically, when you drop object to a objectSlot, check if objectMouseIsOver equals to slot or interface. If it’s interface, Destroy(objectThatYouAreDropping).
