Action script from a mouse/cursor Roll Over

I think I’m being stupid, but how do I trigger an action script from a mouse/cursor Roll Over? I have regular hotspots that have mouse click activated scripts but occasionally I want to run something as the mouse just passes over it. Can’t think how to do it in AC?


  • You'd have to rely on custom scripting, but not much.

    To invoke an ActionList, call its Interact() method.

    To run code when a Hotspot is selected (i.e. mouse-overed), hook into the OnHotspotSelect custom event.

    Sample script (MouseOverInteraction.cs), that gets attached to the Hotspot:

    using UnityEngine;
    using AC;
    public class MouseOverInteraction : MonoBehaviour
        public ActionList actionList;
        private void OnEnable ()
            EventManager.OnHotspotSelect += MySelect;
        private void OnDisable ()
            EventManager.OnHotspotSelect += MySelect;
        private void MySelect (Hotspot hotspot)
            if (GetComponent <Hotspot>() == hotspot)
                actionList.Interact ();
  • Thank you, I'll give that a try :smile:

  • Hey @ChrisIceBox in OnDisable() it should unregister the MySelect right?!
    private void OnDisable () { EventManager.OnHotspotSelect -= MySelect; }

  • Yes - that was a typo.

  • The script works very well to trigger an assigned AC action list on mouse rollover – So I wondered if it possible to extend it to also create the action of On Mouse Leave?

    What I’m trying to achieve is when a mouse cursor enters the region of the hotspot, one action list runs (this it does), but when the play move the mouse off of the hotspot a different action list runs also.

    But... I’m not sure how to extend the code. This is seeming creating a hybrid of Trigger and Hotspot.
