If I were going to use this module to create a lot of games using sprite sheets, or if I was maintaining this for a widely-distributed package, Id probably add some error-checking code to make sure all of the sizes in load_grid_images() come out positive. However, if you don't want to use an event handler, you can let an update function check for input with: pygame.mouse.get_pos() pygame.mouse.get_pressed(). If the image format has per alpha pixel, this information will be lost. In this tutorial, we'll be learning all about sprite sheets. I don't want to edit the source image if I can help it. To make it look like your ship isnt a rectangle, there will need to be transparent portions of the imageeverything around the ship. When rendering graphics to the screen, you have two choices: drawing primitives, like the circles you drew in blue.py, or using image files that youve built in a graphics program. Lets go see the result. We load all the piece images, just as we did before. When I ran chess_game.py, I saw a blank game window. This can be much easier than figuring out the coordinates by hand for each individual piece, especially if youre working with multiple sprite sheets. On line 10, youre in alpha transparency mode. """, # This class handles sprite sheets Lets go see the result. # Position of sprite rect is margin + one sprite size. Here's an example with my stripped down code: Is this the best technique?
