automatically turn document page

BlindRainGames

Hi to all.
AC is friendly, clear and powerfull solution. Thanks, Chris, for your work.
On DocumentUI GO I have the following script to voice over document page:

using UnityEngine;
using AC;

public class DocumentsController : MonoBehaviour
{
    private AudioSource _audio;

    void OnEnable()
    {
        if (KickStarter.player != null)
        {
        _audio = KickStarter.player.speechAudioSource;
            Play(KickStarter.runtimeDocuments.ActiveDocument);
        };
        EventManager.OnMenuElementShift += OnMenuElementShift;
        EventManager.OnMenuTurnOff += OnMenuTurnOff;
    }

    private void OnMenuTurnOff(Menu _menu, bool isInstant)
    {
        _audio.Stop();
    }

    private void OnMenuElementShift(MenuElement _element, AC_ShiftInventory shiftType)
    {
        if (_element is MenuJournal)
            Play(KickStarter.runtimeDocuments.ActiveDocument);
    }

        void Play(Document doc)
        {
            _audio.Stop();
                            int last_page = KickStarter.runtimeDocuments.GetLastOpenPage(doc)-1;
        int line_id = doc.pages[last_page].lineID;
                                    AudioClip clip = KickStarter.runtimeLanguages.GetSpeechAudioClip(line_id, KickStarter.player);
            if (clip != null)
                _audio.PlayOneShot(clip);
                                            }

            void OnDisable()
    {
        EventManager.OnMenuElementShift -= OnMenuElementShift;
        EventManager.OnMenuTurnOff -= OnMenuTurnOff;
    }
        }

All works great, but i need some more functionality. When AudioClip for page is finished playing, I need to automatically turn to next page. And if it is last page, automatically close DocumentUI.
I think, that in Play() method I need to add something like:
StartCoroutine(TurnPage(clip.length));

and:
IEnumerator TurnPage(float time)
{
yield return new WaitForSeconds(time);
//Turn page or close document//
}

But I dont know, how to call method, which handles the buttons (NextPage and CloseDocument) click. Or may be there is more simple way to do this?

Welcome to the community, @BlindRainGames.

Yes - so long as the game isn't paused while the Document is open, then a coroutine should be able to do the job.

You don't need to access the NextPage or CloseDocument buttons - you can modify the Menu and Journal directly.

Try this:

using UnityEngine;
using System.Collections;
using AC;

public class DocumentsController : MonoBehaviour
{

    private AudioSource _audio;


    private void OnEnable ()
    {
        if (KickStarter.player)
        {
            _audio = KickStarter.player.speechAudioSource;
            Play (KickStarter.runtimeDocuments.ActiveDocument);
        }

        EventManager.OnMenuElementShift += OnMenuElementShift;
        EventManager.OnMenuTurnOff += OnMenuTurnOff;
    }


    private void OnDisable ()
    {
        EventManager.OnMenuElementShift -= OnMenuElementShift;
        EventManager.OnMenuTurnOff -= OnMenuTurnOff;
    }


    private void OnMenuTurnOff (Menu _menu, bool isInstant)
    {
        _audio.Stop ();
    }


    private void OnMenuElementShift(MenuElement _element, AC_ShiftInventory shiftType)
    {
        if (_element is MenuJournal)
        {
            Play (KickStarter.runtimeDocuments.ActiveDocument);
        }
    }


    private void Play (Document doc)
    {
        if (doc == null) return;

        _audio.Stop ();
        int last_page = KickStarter.runtimeDocuments.GetLastOpenPage (doc) - 1;
        int line_id = doc.pages[last_page].lineID;
        AudioClip clip = KickStarter.runtimeLanguages.GetSpeechAudioClip (line_id, KickStarter.player);
        if (clip)
        {
            _audio.PlayOneShot (clip);
        }

        StopAllCoroutines ();
        StartCoroutine (TurnPage (clip.length));
    }


    private IEnumerator TurnPage (float time)
    {
        yield return new WaitForSeconds (time);

        Menu myMenu = PlayerMenus.GetMenuWithName ("MyMenu");
        MenuJournal journalToShift = (MenuJournal) myMenu.GetElementWithName ("MyJournal");
        int oldPageIndex = journalToShift.showPage;

        journalToShift.Shift (AC_ShiftInventory.ShiftNext, false, 1);
        journalToShift.RecalculateSize (myMenu.menuSource);
        myMenu.Recalculate ();

        int newPageIndex = journalToShift.showPage;

        if (newPageIndex != oldPageIndex)
        {
            myMenu.TurnOff ();
        }
    }

}

Thanks, @ChrisIceBox. I found the following solution. May be, I don't understand something, but it works.

IEnumerator TurnPage(float time)
{
yield return new WaitForSeconds(time);
Menu menu = KickStarter.playerMenus.GetMenuWithCanvas(GetComponent());
MenuElement btn = null;
//_journal is MenuJournal var.
if (_journal.GetCurrentPageNumber() == KickStarter.runtimeDocuments.ActiveDocument.pages.Count)
btn = menu.GetElementWithName("CloseButton");
else
btn = menu.GetElementWithName("ShiftRight");

        btn.ProcessClick(menu, 0, MouseState.SingleClick);
    }
