Problems displaying my quest in the QuestJournalUi component.

[spokXXI]

Hey Tony,
unfortunately I have a problem with the implementation of quest machine.

The initial situation is:
- I have added the quest machine component to my scene
- created an empty component in the scene and gave it the QuestJournal script
- created a save system component in the quest machine component

All components with the following settings:

map_scene.png (19.77 KiB) Viewed 5261 times

quest_machine_component.png (60.13 KiB) Viewed 5261 times

save_system_component.png (37.07 KiB) Viewed 5261 times

quest_journal_component.png (50.57 KiB) Viewed 5261 times

Process flow:
- i start a quest from my c# script

Code: Select all

PixelCrushers.MessageSystem.SendMessage(gameObject, questData[0], questData[1], questData[2]);

- then I change the scene and see that in the quest HUD component my quest is active (so far so well)
- but when I open the quest journal UI my quest is not entered

I open the journal with this line of code:

Code: Select all

private void Start()
	{
            GameObject questController = GameControllerUtils.FindGameObjectByName(controllerSpace, "QuestController");
            questJournal = questController.GetComponent<QuestJournal>();
        }

        public void Click1()
        {
            questJournal.ToggleJournalUI();
}

quest_journal_state.png (59.97 KiB) Viewed 5261 times

debug_log_messages.png (79.86 KiB) Viewed 5261 times

I've been sitting on this problem for a few days now without finding out why my quest is not entered in the quest journal UI, did I miss something?

Hi,

Would it be possible for you to back up your project, make sure the backup is good, and then update to the current Quest Machine version?

(Note: If you are using Position Saver components with NavMeshAgents, after updating to QM 1.2.40 or higher, tick the Welcome Window's USE_NAVMESH checkbox.)

If the problem still occurs, post another screenshot of the error -- or click on the error in the Console, press Ctrl+C to copy its details to the clipboard, and paste them here.

hi Tony,

I tried as you described, but the same error is displayed. However, now the quest HUD does not show anything either...

Code: Select all

MissingReferenceException: The object of type 'QuestJournal' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Hi,

I think this is happening:

1. Something triggers the quest journal to show or refresh the UI.

2. The quest journal starts the process. It waits until the end of the frame in case other messages also tell the quest journal to show/refresh the UI. This way it will only repaint the UI once instead of multiple times in the same frame.

3. Before the end of the frame, something is causing the quest journal to be destroyed.

If that info doesn't help you identify the issue, would it be possible for you to send a reproduction project to tony (at) pixelcrushers.com?

Hi Alex,

Thanks for putting together the reproduction project. I replied to your email with a question.
