title: pygame - How to write text onto a specific location? Also, how to use coordinates
body: <p>I've been trawling around and I can't really find any good resources on how to write text? I've tried using the rendering command for text but it isn't working for me.</p>
  
  <p>Also, whilst you're here; is there an 'overlay' type of thing where you can see exactly where coordinates are? I can't really figure out how this whole coordinate system works apart from using trial and error each time I use coordinates to pinpoint an area...</p>
  
  <p>Many thanks,</p>
