Hello I dont know why but I seem to be

Ex:

        handle = this.gl.GenVertexArray();
        Bind();
        vbo.Bind();
        ebo.Bind();

        handle = this.gl.GenVertexArray();
        Bind();
        vbo.Bind();
        ebo.Bind();

Yeah it pretty hard sometime XD. It kinda work in my engine now 🙂 My abstraction was making thing out of order😅 Little question should I not be able to create the vbo and vbo prior to creating the vao and just rebinding the vbo and vbo after the vao?

Hello I dont know why but I seem to be

So you said: Gen and bind the vertexArray, Gend, bind and send vertBuffer and gen, bind and send indexBuffer. Right? it wont work using the (void*) 0 too

Hello I dont know why but I seem to be

Yeah if I use (void*) 0 with DrawElement it throw but with UIntPtr.Zero it just do not draw🙃

Hello I dont know why but I seem to be

Also when I use (void*)0 instead of UIntPtr.Zero in DrawElement it throw this: System.ExecutionEngineException
