Archived Forums Questions & Answers

I can add an onClick listener to one of my buttons using:

JumpButton.onClick.AddListener(() => {Jump(); });

I want do the same with another button only I want the event to be a an OnPointer or OnMouse down event. I tried the following:

RotateButton.OnPointerDown.AddListener(() => {RotateVehicle(); });

But this yields error:

Expression denotes a 'method group', where a 'variable', 'value or 'type was expected

Thank you in advance.

There’s no AddListener() method on OnPointerDown(), so you’ll have to implement it the old-fashioned way, by implementing the right interfaces:

using UnityEngine;
using UnityEngine.EventSystems;

public class BT : MonoBehaviour, IPointerDownHandler
{
	public void OnPointerDown(PointerEventData data)
	{
	}
}

etc.
