OnMouseOver UI Button c#
How to detect in script, if the mouse is over a script-created button? If any component is needed, how can you create the object and set the component's settings in the right way?
You don't use OnMouseOver for UI elements, use IPointerEnterHandler Then attach script to game object that you want to implement it on.
example:
using UnityEngine.EventSystems;
public class MyClass: MonoBehaviour, IPointerEnterHandler{
public void OnPointerEnter(PointerEventData eventData)
{
//do stuff
}
Wrong! OnPointerEnter executes only once, while On$$anonymous$$ouseOver executes every frame.
Do you know why Unity choose to duplicate functionality like On$$anonymous$$ouseEnter? And also why they didn't implement an equivalent IPointerXyzHandler to On$$anonymous$$ouseOver?
@JasonSpine I've implemented the analogous function: http://answers.unity.com/answers/1664400/view.html It's a shame they made this design choice. Would be interesting to know why.
I'm building on Flaring-Afro's answer. IPointerEnterHandler works but is not the same as OnMouseOver. To get this behaviour you (unfortunately) also need IPointerExitHandler, a private bool and the Update function such as:
public class UIElement : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{
private bool mouse_over = false;
void Update()
{
if (mouse_over)
{
Debug.Log("Mouse Over");
}
}
public void OnPointerEnter(PointerEventData eventData)
{
mouse_over = true;
Debug.Log("Mouse enter");
}
public void OnPointerExit(PointerEventData eventData)
{
mouse_over = false;
Debug.Log("Mouse exit");
}
}
