Sean Campbell:
I cannot figure out what is wrong with this code and why i keep
getting object.error access violation. the code is simple
tutorial code for SDL and OpenGL what am i doing wrong (the
access violation seems to be with glGenBuffers)
I don't know where your problem is, but you can start helping
yourself with more tidy code (because this makes it more easy to
fix) and adding some asserts on the pointers.
float vertices[] = [
Better to use the D syntax.
int main(string args[]){
DerelictSDL2.load();
DerelictGL3.load();
SDL_Init(SDL_INIT_EVERYTHING);
Better to add a space before the { and some blank lines to
separate logically distinct pieces of your code.
Also, your main perhaps could be void (and use just empty returns
inside it).
SDL_Window* window = SDL_CreateWindow("OpenGL", 100, 100, 800,
600, SDL_WINDOW_OPENGL);
Perhaps it's better to use auto here.
glBufferData(GL_ARRAY_BUFFER, (vertices[0]).sizeof *
vertices.length, vertices.ptr, GL_STATIC_DRAW);
Better to define a little function that computes the bytes of an
array, and call it here, it's less bug-prone.
As a first step you can assert that all the pointers that should
not be null in your program are not null. And then run a debugger.
