03.10.14 - 03.14.14

Played around with some rotational vectors in pygame:
import pygame, random, sys
from pygame.locals import *

WINDOWWIDTH=600
WINDOWHEIGHT=600
BACKGROUNDCOLOR=(0, 0, 0)
FPS=40

def terminate():
    pygame.quit()
    sys.exit()

pygame.init()
mainClock=pygame.time.Clock()
windowSurface=pygame.display.set_mode((WINDOWWIDTH, WINDOWHEIGHT))
pygame.display.set_caption('Test program')
pygame.mouse.set_visible(False)

image1=pygame.image.load('arrowUp.png')
width1, height1=image1.get_size()

while True:
    #playerRect.topleft=(WINDOWWIDTH/2, WINDOWHEIGHT/2)

    while True:
        image2=pygame.transform.rotate(image1, 5)
        width2, height2=image2.get_size()
        for event in pygame.event.get():
            if event.type==QUIT:
                terminate()

            if event.type==KEYDOWN:
                if event.key==K_RIGHT:
                    image2=pygame.transform.rotate(image1, 5)
                    width2, height2=image2.get_size()
                if event.key==K_ESCAPE:
                    terminate()

        windowSurface.fill(BACKGROUNDCOLOR)
        windowSurface.blit(image2, [round(WINDOWWIDTH/2-(width1-width2)/2), round(WINDOWHEIGHT/2-(height1-height2)/2)])
        pygame.display.update()

        mainClock.tick(FPS)

I also got images to change when certain actions are taken
import pygame, random, sys
from pygame.locals import *

WINDOWHEIGHT=600
BACKGROUNDCOLOR=(0, 0, 0)
FPS=40
PLAYERMOVERATE=5

    sys.exit()

#Initalize
pygame.init()

pygame.mouse.set_visible(False)

playerImage=pygame.image.load('arrowUp.png')
playerRect=playerImage.get_rect()

while True:
    playerRect.topleft=(WINDOWWIDTH/2, WINDOWHEIGHT-50)
    moveLeft=moveRight=moveUp=moveDown=False

                    moveRight=False
                    moveLeft=True

            if event.type==MOUSEMOTION:
                playerRect.move_ip(event.pos[0] - playerRect.centerx, event.pos[1] - playerRect.centery)


        if moveLeft and playerRect.left>0:
            playerRect.move_ip(-1*PLAYERMOVERATE, 0)
        if moveRight and playerRect.right<WINDOWWIDTH:
            playerRect.move_ip(PLAYERMOVERATE, 0)
