Help how to display different numbers

Im making an FPS and have an entire ammo system, how do I display the number of ammo without using the debug properties and with a font of my choosing?

A) Text objects
B) A MeshObject with Bitmapfont texture

C) Python and Moguri’s BGUI module

If you’re just going for simple text with minimal customization, a text object is the easiest, simplest method.
