My video tutorial series

Hi everyone,
I had this you tube channel for so long and i never thought about writing about it in unity forums, simply because i had to leave making the video tutorials for long gap between unity 3.5 and unity 5, but now i am back on track and pushing and recording video after video.
So what is these videos about? I will develop an RPG API core in front of camera, i will record every aspect of generating it, from mecanim animation stats for character movement (partially done by now in unity 3.5) up to different editor extensions, and systems needed for any RPG game, although i call it an RPG Core API, i think most of the assets I am creating can be used in different projects and themes, for example, I started my Item System the way Peter at burgzerg arcade done, but as soon as I get to the point to define Item Base Types like weapon, consumables, etc, i change the whole system to use reflection, hence, letting users to develop their own Item Categories and use them.
What I am recording now, is start of a node based editor that later on, will be used for both Dialogue system and Behavior Trees.
So I thought about posting about my channel just in case people missed my tutorials on you tube, here are the play lists :
The mecanim animation system in Unity 3.5 :

Play List

The new series in Unity 5.x (first video is porting that mecanim system to unity 5) :

Play List

Bellow is the list of videos added one by one in the new series, those without the link are the videos that are recorded but not uploaded yet, so this list will get bigger and bigger as the recording and uploading continues, I hope you enjoy it :

Love the video but im stuck here on NullReferenceException: Object reference not set to an instance of an object RPG.NodeEditor.Editor.NodeWorkView.UpdateView (Rect EditorRect, Rect PercentageRect, UnityEngine.Event e, RPG.NodeEditor.NodeGraph graph) (at Assets/Node Editor/Editor/Views/NodeWorkView.cs:25) RPG.NodeEditor.Editor.NodeEditorWindow.OnGUI () (at Assets/Node Editor/Editor/Windows/NodeEditorWindow.cs:40)

 

can i ask if you can put the code for update view method of node work view in a code section and post it, i think either you have a typo somewhere or you maybe in the middle of an episode although as much as i remember, the videos should finish when the code works properly

 

Yeah i have an typo some were just need to try and find it in the video

 

is it coming from ViewBase

public virtual void UpdateView(Rect EditorRect, Rect PercentageRect, Event e, NodeGraph graph)
{
if (ViewSkin == null)
{
GetEditorSkin();
return;
}

ViewRect = new Rect(EditorRect.x * PercentageRect.x,
EditorRect.y * PercentageRect.y,
EditorRect.width * PercentageRect.width,
EditorRect.height * PercentageRect.height);
CurrentGraph = graph;
}

 

all i know error coming from GUI.Box(ViewRect, ViewTitle, ViewSkin.GetStyle("StatusViewBackground"));

 

I don't see any error in that method, if you want to get a better debugging, download unity visual stadio tools, then you can put debug points and see what is getting that null assignment, you should put the debug break point, then attach to unity, after that as soon as you go back to unity while the editor window is open, you should hit that break point

 

On second thought, also, double check the node editor window, it's totally possible that you are not instantiating one of the views or made a mistake by copy/paste

 

ok i will check that thank you

 

Guys, I started posting the videos on 3dbuzz.com, it's much easier for me to send videos there than you tube, registration on 3dbuzz is free, well, some videos will be only for member sponsors but again, their price for member sponsors are really low, if you subscribed, then you can find my tutorials under training > Unity > RPG CORE API
here is the link for that section :
http://www.3dbuzz.com/training/view/untiy-rpg-api-core/chapter-one-node-editor
Also, if you ask me, getting member sponsor and watching the MMO section is well worth it, there are more than 100 - 150 hours of video tutorials on unity just in that one section, there are even more in other sections for you to very well satisfy what you pay for monthly subscription

GUI.Box(ViewRect, ViewTitile, ViewSkin.GetStyle("WorkViewBackground"));

please help
Where is the mistake?
