Use of mouse buttons in a mouse manager script
I'm working on a mouse manager script. I've instantiated a prefab from a list and displayed each item on the screen. I have the color change when the pointer enters and changes back when exiting with the event system.
What I want to do is have it when you click the left button, it does one operation and it does a second operation if you right click. Since this script is on a prefab, I wasn't sure if I should just use Update() or if there was some other recommended way to do it. Thanks!
I finally found the answer. If anyone else is having the same problem. This script will work!
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.Events;
public class RightClick : MonoBehaviour, IPointerClickHandler
{
public UnityEvent leftClick;
public UnityEvent middleClick;
public UnityEvent rightClick;
public void OnPointerClick(PointerEventData eventData)
{
if (eventData.button == PointerEventData.InputButton.Left)
leftClick.Invoke ();
else if (eventData.button == PointerEventData.InputButton.Middle)
middleClick.Invoke ();
else if (eventData.button == PointerEventData.InputButton.Right)
rightClick.Invoke ();
}
}
Just attach it to your game object and use it instead of OnPointerClick.
instead of checking if mouse button clicked in update, just add an Event trigger (pointer Click) and create a method like clickHappened() and assign it to event trigger. in clickHappened() method , you can take base event data and check witch mouse button is clicked, left or right.
this way is more performance friendly as far as i know.
So I'm guessing the method needs a parameter taking in a base event data variable?
Unless I did it wrong, it's only showing me the coordinates of the click, not which button was clicked.
public void OnClick(BaseEventData clicker)
{
Debug.Log (clicker);
}
