The pysfml site didn't really have anything that showed this being used and looking at the C++ version didn't really help either. What I'm trying to do is draw a full progress bar onto the screen but have the texture rectangle set to only show part of it to represent what data has been loaded. What I have right now is this:
self.loadBar.texture_rectangle = sf.Rectangle((0,0),(relativeSize, 20))
But it doesn't work, it still shows the whole thing. Am I not using it right?
