How to display score on Pygame?

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 like 5 different levels that range in level of difficulty. eg level 1 will display like 2 boxes and level 2 will display like 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 doesnt really work until I try to close the window, and even then it only goes halfway. I'm thinking its how I defined the functions but I'm not to certain. Any help would be appreciated.

Answer 1

the main problem why it is not working at the moment is:

• your globals rows and columns are set to 20 but your board has only 9 fields, this is why most randomly selected coords are off the board

then, you do not control that the same coord is chosen 2 times.

in general, I would advise choosing better names, especially for displayOtherColor which assembles your target coordinates for each level.

for your question how to display score, I would propose setting it as caption, as you are already doing with the running time.
