it seems like I dont connect the player input directly to the very first <Start> node, it does not do that though

Hi,

Please temporarily comment out these lines in AbstractDialogueUI.cs:

debugShowResponses.png (66.91 KiB) Viewed 845 times

Then reproduce the error and reply with the new error info.

Here it is:

But if I put "Continue@1.5" (I made a shortcut as {{c15}}) for the START node, everything works fine.
If its only "Continue@1.0", same error occurs.

Hi,

Are you sure you updated to version 2.2.30? (Please check Plugins/Pixel Crushers/Dialogue System/_README.txt.) UIPanel.cs Line 314 should not throw this error:

NullReferenceException: Object reference not set to an instance of an object
PixelCrushers.UIPanel.SetFocus (UnityEngine.GameObject selectable) (at Assets/Plugins/Pixel Crushers/Common/Scripts/UI/UIPanel.cs:314)

Sorry it was 326.

Here it is with 2.2.30.

Line 326 is:

Code: Select all

UnityEngine.EventSystems.EventSystem.current.SetSelectedGameObject(null);

Does your scene have an EventSystem?

[fkkcloud]

I am using Rewired.

It works if I put 1.5 second delay ("Continue@1.5;") on the START node somehow (If I put 1.0 second delay aka "Continue@1.0;", it crashes).

But RewiredEventSystem is child class of EventSystem

[Tony Li]

Is the Rewired Event System present when the scene starts? Or only after 1.5 seconds?

[fkkcloud]

It is always present because its part of GameManager which is DontDestroyOnLoad since beginning of the application.

[Tony Li]

Would you please confirm in your project that line 326 of Assets/Plugins/Pixel Crushers/Common/Scripts/UI/UIPanel.cs is actually this:

Code: Select all

UnityEngine.EventSystems.EventSystem.current.SetSelectedGameObject(null);
