<p>Well In a game I am working on I have recently allowed mouse click to shoot wherever the mouse is. But the bullets will only shoot at either a 0 degree angle or 45 degree angle. I am wanting to try and make this to be 360 degrees. Here is the code for my main game file:</p> <pre><code>import pygame, sys import random import pygame.mixer import Funk, math from time import sleep from player import * from zombie import * from level import * from bullet import * from constants import * from Drops import * from menus import * from meteors import * import menu as dm class Game(): def __init__(self): pygame.init() pygame.mixer.init() pygame.mixer.music.load('data/sounds/menugame.ogg') pygame.mixer.music.set_volume(0.5) pygame.mixer.music.play(-1) # A few variables self.gravity = .50 self.red = (255, 0, 0) self.darkred = (200, 0, 0) self.darkblue = (0, 0, 200) self.darkgreen = (0, 200, 0) self.gameover = pygame.image.load('data/images/gameover.png') self.victory = pygame.image.load('data/images/victory.png') # Bullets and Drops self.bullets = [] self.gameDrops = [] # Screen icon = pygame.image.load('data/icons/moonsurvival.bmp') size = SCREEN_WIDTH, SCREEN_HEIGHT self.screen = pygame.display.set_mode(size) pygame.display.set_caption('Moon Survival!') pygame.display.set_icon(icon) self.screen_rect = self.screen.get_rect() # Moon / Background self.moon = Background() self.text1 = pygame.image.load('data/images/TextSlides/Text1.jpg') self.text2 = pygame.image.load('data/images/TextSlides/Text2.jpg') # Zombies and boss self.zombies = [] self.bosses = [] #for i in range(15): # self.zombies.append( Zombie(random.randint(0,1280), random.randint(0,0)) ) self.zombieskilled = 0 # Spawn time self.last_spawn_time = 0 # Meteors self.meteors = [] # Menus self.menuStartGame = MenuStartGame(self.screen, self) self.menuAbout = MenuAbout(self.screen, self) #self.menuSettings = MenuSettings(self.screen, self) self.menuScene = MenuScene(self.screen, self) self.menuGameOver = MenuGameOver(self.screen, self) #self.menuGameFinish = MenuGameFinish(self.screen, self) # Player self.player = Player(25, 320, self.gravity) # Font for text self.font = pygame.font.SysFont(None, 72) self.point = self.player.rect.x, self.player.rect.y self.max_radius = math.hypot(self.screen_rect.w, self.screen_rect.h) self.mouse_angle = (0, 0) # game over self.gameover_text = self.font.render("The Aliens Are Too Good", -1, (255, 0, 0)) self.gameover_rect = self.gameover_text.get_rect(center=self.screen.get_rect().center) # game state self.game_state = STATE_MENU def run(self): clock = pygame.time.Clock() # "state machine" RUNNING = True PAUSED = False GAME_OVER = False # Game loop while RUNNING: # (all) Events if self.game_state == STATE_INGAME: print(self.mouse_angle) for event in pygame.event.get(): if event.type == pygame.QUIT: RUNNING = False elif event.type == pygame.KEYDOWN: if event.key == pygame.K_s: if self.player.power == POWER_TRIBULLETS: self.bullets.append(Bullet(self.player.rect.x + 35, self.player.rect.y + 35, self.mouse_angle)) self.bullets.append(Bullet(self.player.rect.x + 30, self.player.rect.y + 30, self.mouse_angle)) self.bullets.append(Bullet(self.player.rect.x + 35, self.player.rect.y + 25, self.mouse_angle)) else: self.bullets.append(Bullet(self.player.rect.x + 30, self.player.rect.y + 30, self.mouse_angle)) if event.key == pygame.K_ESCAPE: RUNNING = False elif event.key == pygame.K_p: # set state to paused self.game_state = STATE_PAUSED elif event.type == pygame.MOUSEBUTTONDOWN: if event.button == 1: if self.player.power == POWER_TRIBULLETS: self.bullets.append(Bullet(self.player.rect.x + 35, self.player.rect.y + 35, self.mouse_angle)) self.bullets.append(Bullet(self.player.rect.x + 30, self.player.rect.y + 30, self.mouse_angle)) self.bullets.append(Bullet(self.player.rect.x + 35, self.player.rect.y + 25, self.mouse_angle)) else: self.bullets.append(Bullet(self.player.rect.x + 30, self.player.rect.y + 30, self.mouse_angle)) # Player/Zombies events self.player.handle_events(event) # (all) Movements / Updates self.player_move() self.player.update() for z in self.zombies: self.zombie_move(z) z.update(self.screen.get_rect()) for boss in self.bosses: self.boss_move(boss) boss.update(self.screen.get_rect()) for b in self.bullets: b.update() for tile in self.moon.get_surrounding_blocks(b): if tile is not None: if pygame.sprite.collide_rect(b, tile): # Destroy block x = tile.rect.x / tile.rect.width y = tile.rect.y / tile.rect.height self.moon.levelStructure[x][y] = None try: self.bullets.remove(b) except: continue for m in self.meteors: m.update() for tile in self.moon.get_surrounding_blocks(m): if tile is not None: if pygame.sprite.collide_rect(m, tile): # Destroy block x = tile.rect.x / tile.rect.width y = tile.rect.y / tile.rect.height self.moon.levelStructure[x][y] = None self.moon.levelStructure[x + 1][y + 1] = None self.moon.levelStructure[x -

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
