object reference not set to instance of object on a static method call

Nnut

so im trying to use an opengl binding package (Veldrid.OpenGLBinding) but, when i call any of the methods, it says "Object reference not set to an instance of an object". I'm guessing I'm not using it right but it has absolutely zero documentation so I'm lost

        public void Run()
        {


            GL.Initialize();
            Glfw.Init();

            window = new Window(800, 600, "W");

            GL.ClearColor(255, 255, 255, 255);
            
            while (!window.ShouldClose())
            {
                window.Clear();

                window.SwapBuffers();
                Glfw.PollEvents();
            }
        }

        public void Run()
        {


            GL.Initialize();
            Glfw.Init();

            window = new Window(800, 600, "W");

            GL.ClearColor(255, 255, 255, 255);
            
            while (!window.ShouldClose())
            {
                window.Clear();

                window.SwapBuffers();
                Glfw.PollEvents();
            }
        }

I tried switching to OpenGL.NET and same issue GL.ClearColor throws this error

are you in release mode? also we usually use silk.NET(Most Recommended) or OpenTK

Nnut

11/21/2023

i didnt wanna use either of those because they lock you into their windowing system that i dont like i wanted to just use glfw windowing directly and it doesnt work in debug nor release mode

TTheRanger

11/21/2023

lock you into their windowing system ?

Nnut

11/21/2023

you know, extend IWindow, all your code goes in OnUpdateFrame, OnRenderFrame, etc

i just wanted a more c style glfw setup

TTheRanger

11/21/2023

never used OpenGL.NET so no idea

Nnut

11/21/2023

do you know of anything that doesnt lock you into the windowing system i thought silk would work since it had glfw bindings but it didnt have any opengl bindings i could use

TTheRanger

11/21/2023

did you follow the tutorial exactly? perhaps you missed something

Nnut

11/21/2023

yeah, ithink

found some code in so

       Glfw.Init();
            GLFWwindow window = Glfw.CreateWindow(1080, 720, "Yeet", null, null);
            Glfw.MakeContextCurrent(window);
            Gl.Initialize();

       Glfw.Init();
            GLFWwindow window = Glfw.CreateWindow(1080, 720, "Yeet", null, null);
            Glfw.MakeContextCurrent(window);
            Gl.Initialize();

perhaps you need to initialize it this way

Nnut

11/21/2023

where did you find that?

TTheRanger

11/21/2023

stack overflow

Nnut

11/21/2023

could you link it my glfw might be the problem (somehow?? idk)

TTheRanger

https://stackoverflow.com/questions/61318104/how-do-i-initialize-opengl-net-with-glfw-net ur issue probably is, it doesnt know which window to use ClearColor on

Nnut

11/21/2023

 Glfw.Init();
 Window window = Glfw.CreateWindow(1080, 720, "Yeet", GLFW.Monitor.None, Window.None);
 GL.Initialize();
 Glfw.MakeContextCurrent(window);
 GL.ClearColor(255, 255, 255, 255);
 
 while (true)
 {
     Glfw.PollEvents();
 }

 Glfw.Init();
 Window window = Glfw.CreateWindow(1080, 720, "Yeet", GLFW.Monitor.None, Window.None);
 GL.Initialize();
 Glfw.MakeContextCurrent(window);
 GL.ClearColor(255, 255, 255, 255);
 
 while (true)
 {
     Glfw.PollEvents();
 }

this is what ive got now same crash

GL.Initialize(); Glfw.MakeContextCurrent(window); but the code calls Glfw.MakeContextCurrent(window); before GL.Initialize(); in the stack overflow page

the solution doesnt also somehow, a different overload of clearcolor fixes it if i use float,float,float,float instead of nint, nint, nint, nint it works ?? okayt then

TTheRanger

11/21/2023

nint or int?

Nnut

11/21/2023

nint dont know exactly what that is

TTheRanger

11/21/2023

thats unsafe, the overload is probably meant for something else nint is IntPtr

Nnut

11/21/2023

i figured

TTheRanger

11/21/2023

or simply a pointer like in C

Nnut

11/21/2023

thats why i tried the different overload

TTheRanger

11/21/2023

yeah the color values are normalized 0 to 1 instead of 0 to 255

Ttannergooding

11/21/2023

IntPtr is not a pointer it is a pointer sized integer Int32 is 32-bits, Int64 is 64-bits IntPtr is ptr-bits

Why not? Silk doesn’t lock you into any windowing system.

Nnut

11/21/2023

silk makes you use its window class, and you can create a window andm ake your own event loop like you can with glfw but i switched to silk anyways and im still having trouble

PPerksey

11/21/2023

no it doesn’t, you can use silk without the windowing class what trouble are you having?

Nnut

11/21/2023

why is it all unsafe? why arent there functions to upload uniform matices safely? why do i have to make an unsafe context, get a pointer to the matrix struct, and use that

PPerksey

11/21/2023

Any time you’re using anything that isn’t a C# function you are using unsafe, any library that tries to convince you otherwise is lying. Even if you don’t have to use the unsafe keyword, make no mistake it is unsafe. You shouldn’t try to hide from it just because it has a scary name. You are leaving the scary of the .NET runtime. however, we do provide overloads for using refs, so you could for example take a ref to the first matrix member instead The tutorials do not use these overloads tmk, they predate the overloads existence and we didn’t feel like it was a high priority to change them.

Nnut

how can i get this ref to the first member? nvm i just bit my tongue and used pointers
