I need help going from my starting menu to my game. At the moment i would like to prompt the user to hit enter and then go directly into the playable part of the program. However, i cant figure out how to clear what im doing and start up the game part. Heres the code so far (i will add the interactive part at the title menu later when i learn how from you guys):

[source lang="python"]import pygame, randomimport randintimport pplrtyimport sysfrom pygame.locals import *pygame.init()FPS = 30fpsClock = pygame.time.Clock()#variablesx = randint.xyear = 2011p = pplrty.pmousepos = pygame.mouse.get_pos()#get colorsWHITE = (255, 255, 255)RED = (255, 0, 0)#get display stuffDISPLAY = pygame.display.set_mode((640,480))pygame.display.set_caption('Program')#create fontsfontObj1 = pygame.font.Font('freesansbold.ttf', 16)#make wordstextObj1 = fontObj1.render('Hit Enter', True, RED)RectObj1 = textObj1.get_rect()RectObj1.center = (315, 240)#get imagestitle = pygame.image.load('title.png')stitle = pygame.transform.scale(title, (264, 64))bg = pygame.image.load('bg.png')sbg = pygame.transform.scale(bg, (640, 480))#fill the display with good stuffDISPLAY.blit(sbg, (0, 0))DISPLAY.blit(stitle, (188, 10))DISPLAY.blit(textObj1, RectObj1)#Main Loopwhile True: for event in pygame.event.get(): if event.type == pygame.KEYDOWN: if event.key == pygame.K_RETURN: year += 1 if event.type == QUIT: pygame.quit() sys.exit() pygame.display.update()[/source]

keep in mind its still very underdeveloped.

You should do some reserach on state machines.

At the most basic level, you could start with something like this:

def menu():
	... whatever you would typically do for the menu
	if keyHit(ENTER):
		return game

def game():
	... your game loop
	 if (SHOULD_GO_BACK_TO_MENU):
		return menu

state = menu

while True:
	state_next = state()
	if state_next:
		state = state_next
