Would I create the thread in the main class instead then?

No, you would not create ANY thread manually. The thread has already been created by the operating system, which like I said three times now is executing your Java program just fine. It IS ALREADY a thread and you should not do anything like creating yet another useless thread.

Regarding the pastebin: You have A WHOLE LOT of OpenGL errors in your application. You MUST resolve those before continuing. Basically almost all of your calls generate OpenGL errors because you either feed them invalid arguments or they are being executed at a wrong time.

So I managed to fix most of the errors by redoing the whole code but now I have a new issue:
Code: [Select]
[error][1] Vertex array [0] enabled but not initialized
  Stacktrace: Engine.Renderer.render(Renderer.java:37)
              Game.gameLoop.loop(gameLoop.java:63)
              Game.gameLoop.main(gameLoop.java:19)
How do you initialize a vertex array?

How do you initialize a vertex array?
By calling glVertexAttribPointer(...) (or one of its fixed-function pipeline equivalents) while having the VBO bound to GL_ARRAY_BUFFER via glBindBuffer(...).

EDIT: Also please re-download the LWJGLX/debug Addon from https://www.lwjgl.org/customize. There have been changes to improve the error logging.

I do have the pointer, but I changed the GL_ARRAY_BUFFER to GL_ELEMENT_ARRAY_BUFFER because I'm using glDrawElements(), do I have to only use gl array buffer for initializing?

If you do indexed rendering with glDrawElements(), then you need both. You need the actual vertex data (which is stored in the vertex attributes that you enable via glEnableVertexArray() and initialize via glVertexAttribPointer()) and you need the element/index buffer, which you bind via glBindBuffer() and GL_ELEMENT_ARRAY_BUFFER.

I'm a little confused on what you mean, here is the part that was in question:
Code: [Select]
GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, vboID);
GL15.glBufferData(GL15.GL_ELEMENT_ARRAY_BUFFER, flipByteBuffer(indice.indices), GL15.GL_DYNAMIC_DRAW);
GL20.glVertexAttribPointer(attributeNumber, 3, GL11.GL_FLOAT, false, 0, 0);
GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, 0);

The element/index array buffer, bound to GL_ELEMENT_ARRAY_BUFFER, is not a vertex attribute. You can only enable and initialize vertex attributes.
Before you continue, please go ahead and search for "OpenGL VBO" tutorials and examples and read them.

Thanks for the suggestion, it managed to fix that problem, however I am still getting the 'not responding' problem. When running with the lwjgl debug, I don't get any errors except for a stack trace. Would you happen to know what it means/is it an error? Almost all of the opengl lwjgl tutorials are for lwjgl 2 or are outdated.

Is just a notification from the graphics driver about the residency of the buffer object (in video memory). It is not an error or a warning.

Regarding the "not responding" behaviour: Are you sure that you are calling glfwPollEvents() in a loop continuously? This method needs to be called in order for your application/process to handle window events that the operating system sends to your application. When your application does not poll those events and react accordingly by calling glfwPollEvents() then the operating system assumes the process has frozen up and will show that to the user by overlaying the processe's window.
