Problems with c# headers (Loading Scene and access violation)

[Blitzbat]

Hi !

 

I have problems with the c# headers

 

If I'm trying to load a scene i can't see anything...

 

I have tried to get an entity by key but than a AccessViolationException was thrown (in Core.EntityPosition(this.Pointer, position, 0))

 

Here is my code:

Scene s = Scene.Load("abstract::test.sbx");
Vector3 campos = s.GetChild("camera_start").Position; //here the AccessViolationException is thrown.
this.maincam.Position = campos;

 

 

Thanks for your help!

Make sure you check that the camera returned by s.GetChild is not null.

AccessViolation is generally symptom of a zero-value pointer (I think GetChild returns such nullpointer entity instead of null if the child has not been found, but not sure on this).

[Blitzbat]

Thank you for your suggestions!

 

I will check it if I'm back home!

Fixed this possible flaw for the next headers.

Hey!

 

Ok. Something is being bad here... This simple code does not work . I only see a black screen.

 

Graphics.Initialize(this.width, this.height);
Framework.Initialize(true);

if (Framework.Layers.Main.World.Pointer == World.NullPointer) {
   return;
}

Texture.TFilterMode = 1;
Texture.AFilterMode = 4;

Graphics.Initialize(this.width, this.height);
Framework.Initialize(true);

if (Framework.Layers.Main.World.Pointer == World.NullPointer) {
return;
}
Texture.TFilterMode = 1;
Texture.AFilterMode = 4;

Entity box = Mesh.CreateCube();
box.Move(new Vector3(0.0f, 0.0f, 10.0f));
while (!Window.HasRequestedClose()) {

World.Update(1);

World.Render();

Graphics.Flip();



}

Leadwerks.Engine.Terminate();

 

Can someone help me?

 

Thanks!

There is no camera. Try creating one with:

Camera camera = new Camera();

By the way, some parts of your code are repeated.

Hi!

 

Yes sorry it was a copy and paste bug

 

Now i have creaed a camera. But the same here... Black screen

[L B]

Could you post your complete code, without that copy/paste bug?

[Blitzbat]

And here it comes

 

       public void Run() {

           this.config.LoadFile("config.ini");

           this.height = this.config.GetIntValue("video", "height");
           this.width = this.config.GetIntValue("video", "width");
           this.depth = this.config.GetIntValue("video", "depth");

           Graphics.Initialize(this.width, this.height);

           new World();

           Camera cam = new Camera();
           Entity box = Mesh.CreateCube();
           box.Move(new Vector3(0.0f, 0.0f, 5.0f));
           while (!Window.HasRequestedClose()) {

               World.Update(1);

               World.Render();


               Graphics.Flip();



           }

           Leadwerks.Engine.Terminate();
       }

I have no idea. 10 might be a bit far for the cube. Try 5, especially if your window is small.

Also, try World.Render(-1).

[ZioRed]

The last code works for me, I see a white cube in the center of the black window (used 800/600 for width/height)

[Blitzbat]

the last code does not work for me...

Thanks for the help but I have switched to c++ now.

 

It works very well!

 

Thanks so far!

Sad, we lost a user to an unreproduceable bug. Wait is that a word?

[Davaris]

When I've run into problems like that, its because I haven't added the correct version of a dll, or other relevant file to my working directory.

how strange , this topic reminds me another one http://leadwerks.com/werkspace/index.php?/topic/2270-problems-with-delphi-headers/

 

same story, same end ... C++ is "magic"

[Rick]

The LE C++ library is just more mature and has been around longer. The C# library has gone through some revisions and has been around a shorter amount of time so it just needs time to become stable. Although the lesson for anyone maintaining a different language library is to not always mess around with how it works because people get annoyed when things change all the time.

[TylerH]

I don't think someone's inability to code means the wrapper/framework is flawed. The code posted had blatant errors that would cause this problem, and with a straight copy of the code I do infact get the described issue .

 

Lazlo has cooked up quite the "book" on this to make sure that C# has the strongest support in the area of new users.

[Rick]

Yeah, I wasn't trying to imply that. I was just saying that if a library changes often enough people get confused (with all the old posts out there) and it makes people not "trust" it enough to use it in their projects.

 

The old posts and such is a real problem I think. For someone new in LE C# it can be confusing as to what you are supposed to us (currently).

[cocopino]

Is there a tutorial/guide somewhere to set up LE with C#?

Visual Studio 2010 is looking fantastic.

All bugs that i will find will be reported. I'm still here for c# development.

But for my current project I'm using c++

I don't know how will be different the code from the new incoming wrapper, but I wrote a "getting started" which used the 1.32 version of the wrapper (I don't think the new wrapper will be enough different to invalidate that tutorial or the other one I wrote for Lights, if needed I will update them when the new will be released).

Thanks ZioRed, that worked!

Have you (or anyone else) got it working inside a container, so I can use the Windows Forms Controls at the same time?

[ZioRed]

I wrote a simple program which I use as base for some editors (it uses 1.32 version of wrapper and LETKControl).

[cocopino]

Nice!
