Buttons not working? Anyone know why?

Hi when i push this button nothing is happening, could anyone tell me why? I tried to post everything here involved.

 

Do you have an EventSystem in the scene?

Is the button responding to the mouse hovering over it, eg, darkening? If not, maybe there's something in front of it with RaycastTarget checked?.

If it is responding, remove and reattach its delegate. IF that does not work, make a fresh script with a single Debug.Log() output in a public function, connect that.

 

Have you found your problem? Make sure the Coroutine is called on an active Object (like Update()). If you want to deactivate your GameObject you can call it on any other active MonoBehaviour. E.g. create a field for the QuestManager and then: _questManager.StartCoroutine(...).
