VBO doesn't show up on the screen

Newbie & Debugging Questions

Hi, I’m new to LWJGL and OpenGL. I know the basics like intermediate mode and shaders. I have an out-of-focus idea on GL_PROJECTION, GL_MODELVIEW and glLoadIdentity() (I haven’t completely nailed these ones yet). I recently started using VBOs as I’m aware that the intermediate mode is deprecated. I managed to get it working in a simple program, but now I have hit a wall as to what the problem may be. I’m hoping that somebody will tell me where I’m going wrong(because I definitely do).

Here’s the main code:


	public static void main(String[] args) {
		
		Program app = new Program(800, 600, "VBO 3D Test", false); //creates a window
		
		Camera cam = new Camera(60, 800 / 600); //fov, aspect
		cam.setPosition(5, 5, 5);
		cam.look(0, 0, 0); //this calls gluLookAt(), the parameters are the position where the camera looks
		
		Tile t = new Tile();

		while(!Display.isCloseRequested()) {
			
			glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

			t.draw(); //draws a white, horizontal rectangle at 0,0,0 (it should show up, but doesn't)

			//any intermediate mode here -will- show up on the screen
			
			Display.update();
			Display.sync(60);
		}
		
		app.destroy();
	}

Methods from class Tile:


	private void generateVBO() {
		
		vboFloor = glGenBuffers();
		
		floorVertexData = BufferUtils.createFloatBuffer(4 * 3);
		floorVertexData.put(new float[]{-0.5f, 0, -0.5f,
				0.5f, 0, -0.5f,
				0.5f, 0, 0.5f,
				-0.5f, 0, 0.5f});
		floorVertexData.flip();
		
		glBindBuffer(GL_ARRAY_BUFFER, vboFloor);
		glBufferData(vboFloor, floorVertexData, GL_STATIC_DRAW);
		
		glBindBuffer(GL_ARRAY_BUFFER, 0);
	}
	
	public void draw() {

		glBindBuffer(GL_ARRAY_BUFFER, vboFloor);
		glVertexPointer(3, GL_FLOAT, 0, 0L);
		
		glEnableClientState(GL_VERTEX_ARRAY);
		glDrawArrays(GL_TRIANGLE_FAN, 0, 4);
		glDisableClientState(GL_VERTEX_ARRAY);
		
		glBindBuffer(GL_ARRAY_BUFFER, 0);
	}

When creating the display I use:


glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

I don’t know why the VBO doesn’t show up on the screen, the exact same code works in the other project, the only difference is that previously I have used glOrtho because it was a 2D project, now it’s in 3D (my first attempt at 3D in OpenGL btw). If you need any other snippets just say it. Any help is really appreciated!
