Question

我知道你必须拥有除玩家移动之外的一切，但我无法弄清楚如何将移动背景集成到我的代码中。目前我有一个移动屏幕的字符。并希望屏幕移动角色。很多人都在使用Vector 2来实现他们的速度，我也很困惑。这是播放器对象的当前代码：

class Player(object):
def __init__(self, x, y, width, height):
    self.x = x
    self.y = y
    self.width = width
    self.height = height
    self.vel = 7
    self.left = False
    self.right = False
    self.up = False
    self.down = False
    self.walkCount = 0
    self.standing = True

def draw(self, gameDisplay):
    if self.walkCount + 1 >= 27:
        self.walkCount = 0

    if not self.standing:
        if self.left:
            gameDisplay.blit(walkLeft[self.walkCount // 3], (self.x, self.y))
            self.walkCount += 1
        elif self.right:
            gameDisplay.blit(walkRight[self.walkCount // 3], (self.x, self.y))
            self.walkCount += 1
    else:
        if self.right:
            gameDisplay.blit(walkRight[0], (self.x, self.y))
        else:
            gameDisplay.blit(walkLeft[0], (self.x, self.y))
def redrawgamewindow():
gameDisplay.blit(bg, (0, 0))
char.draw(gameDisplay)
goblin.draw(gameDisplay)
for fireball in fireballs:
    fireball.draw(gameDisplay)
pygame.display.update()

def redrawgamewindow():
gameDisplay.blit(bg, (0, 0))
char.draw(gameDisplay)
goblin.draw(gameDisplay)
for fireball in fireballs:
    fireball.draw(gameDisplay)
pygame.display.update()

重绘功能：

def redrawgamewindow():
gameDisplay.blit(bg, (0, 0))
char.draw(gameDisplay)
goblin.draw(gameDisplay)
for fireball in fireballs:
    fireball.draw(gameDisplay)
pygame.display.update()

主循环

char = Player(250, 410, 64, 64)
run = True
fireballs = []
while run:
    clock.tick(27)

for event in pygame.event.get():
    if event.type == pygame.QUIT:
        run = False

for fireball in fireballs:
    if 500 > fireball.x > 0:
        fireball.x += fireball.vel
    else:
        fireballs.pop(fireballs.index(fireball))

keys = pygame.key.get_pressed()
buttons = pygame.mouse.get_pressed()

if keys[pygame.K_SPACE]:
    if char.left:
        facing = -1
    else:
        facing = 1
    if len(fireballs) < 5:
        fireballs.append(projectile(round(char.x + char.width // 2), round(char.y + char.height // 2), facing))

if keys[pygame.K_a] and char.x > char.vel:
    char.x -= char.vel
    char.left = True
    char.right = False
    char.standing = False
elif keys[pygame.K_d] and char.x < display_width - char.width - char.vel:
    char.x += char.vel
    char.right = True
    char.left = False
    char.standing = False
else:
    char.standing = True
    char.walkCount = 0

if keys[pygame.K_w] and char.y > char.vel:
    char.y -= char.vel
    char.up = True
    char.down = False
elif keys[pygame.K_s] and char.y < display_height - char.height - char.vel:
    char.y += char.vel
    char.down = True
    char.up = False
else:
    char.down = False
    char.up = False

redrawgamewindow()

pygame.quit()
quit()

让相机在pygame中关注玩家
