Shooter With Joystick

Since it's Labor Day weekend, I had some time to work with my son on game concepts.  I went back to the lesson on pygame.joystick, that my son worked on last year.  So far, we put about two hours into the lesson.  It's a fun, easy and rewarding lesson that uses simple math.  It's also short enough so that we didn't use functions or classes.

The background is a simple static image that doesn't move. The gun sight is also a single image with transparent background enabled. My student didn't develop any targets yet because he went out to a Labor Day BBQ.

Here's the code:

import pygame, sys from pygame.locals import * GREEN = (0, 255, 0) BLACK = (0, 0, 0) WHITE = (255, 255, 255) pygame.init() windowSurface = pygame.display.set_mode((800, 600), 0, 32) ### Tells the number of joysticks/error detection joystick_count = pygame.joystick.get_count() print ("There is ", joystick_count, "joystick/s") if joystick_count == 0: print ("Error, I did not find any joysticks") else: my_joystick = pygame.joystick.Joystick(0) my_joystick.init() crosshairs = pygame.image.load("crosshairs.png") background = pygame.image.load("shooter/image_library/background.jpg") x = 300 y = 300 ### Creates rectangle Rectangle = pygame.Rect( x, y, 100, 100) Back = pygame.Rect(0, 0, 800, 600) while True: for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() h_axis_pos = my_joystick.get_axis(0) v_axis_pos = my_joystick.get_axis(1) print (h_axis_pos, v_axis_pos) if x < 0: x = 1 elif x > 700: x = 700 else: x = int(x + h_axis_pos * 5) if y < 0: y = 0 elif y > 500: y = 500 else: y = int(y + v_axis_pos * 5) print ("rectangle left, top", x, y) Rectangle.left = x Rectangle.top = y ###windowSurface.fill(WHITE) windowSurface.blit(background, Back) windowSurface.blit(crosshairs, Rectangle) pygame.display.update()
