如何在Pygame上显示玩家的分数？

Question

I'm a new programmer working on a memory game for my computer science summative.The game goes like this: the computer displays random boxes at random positions and then the user has to guess where the boxes are and click on it.

I'm basically done, except right now I'm trying to create 5 different levels that range in level of difficulty. eg level 1 will display 2 boxes and level 2 will display 5, etc. And then if the user gets through all levels they can play again. I know its a lot but I really want to get an A on this.

But right now I'm stuck because it doesn't really work until I try to close the window, and even then it only goes halfway. Any help would be appreciated.

You may want to use the pygame.font module. http://pygame.org/docs/ref/font.html

• First, load a font, either from a file or from one of the system font functions.
• Call YourFontObject.render(your_text_string) . That'll return a Surface that contains the string rendered in the given font. Note, you can't use newline ( \\n ) characters! You'll have to do the spacing yourself.
• Blit this Surface onto the screen after everything else so nothing will obscure it.

Also, you don't need the pygame parameter in your functions.

Hope this helps.
