我正在用 pygame 编写一个小游戏。我想添加四个不同的摄像机视角，以便能够从四个侧面查看屏幕。第一个摄像机视角工作得很好（玩家在中心，地牢沿着移动）。然而，在第二个视角中，玩家不会停留在同一个位置。我确实添加了其他视角，但还没有对它们进行处理，所以我只会给出与第一个和第二个视角相关的代码。

WIDTH, HEIGHT = 1000, 600
WINDOW = pygame.display.set_mode((WIDTH, HEIGHT))

#Debug-Screen
pygame.font.init()
FONT = pygame.font.SysFont('comicsans',20)

core_diameter = 32
parcel_size = 64

PLAYER = pygame.transform.scale(pygame.image.load("assets/blob.png"),(core_diameter,core_diameter))
GROUND_PARCEL = pygame.transform.scale(pygame.image.load("assets/stone.png"),(parcel_size,parcel_size))

#creating the statics of the dungeon

    WINDOW.fill((0,0,0))

        y_tot = int(HEIGHT // parcel_size + 2) 
        x = xpos - WIDTH/(2*parcel_size) #bitmap position at window edge (top left)
        y = ypos - HEIGHT/(2*parcel_size) 
        x_start = int(int(x) * parcel_size - x * parcel_size) #window position of generation start
        y_start = int(int(y) * parcel_size - y * parcel_size)

                elif grid_x != -1:
                    grid_x = int(j + x + 1)
                if grid_x == 0 and x != int(x) and x < 0: 
                    hinder_gen_bug_x = True
                    
                #...and the display
                if 0 <= grid_y < DUNGEON_HEIGHT and 0 <= grid_x < DUNGEON_WIDTH: #if in dungeon

        x_start_square = math.ceil(x_edge_coords)
        x_start_display_pos = -(x_start_square-x_edge_coords)*parcel_size
        y_start_square = int(y_edge_coords)
        y_start_display_pos = -(y_edge_coords-y_start_square)*parcel_size
        for i in range(y_tot):

                        WINDOW.blit(GROUND_PARCEL, (x_start_display_pos + j * parcel_size, y_start_display_pos + i * parcel_size)) #window

    WINDOW.blit(PLAYER, (core.x, core.y))
    coords = FONT.render("X:" + str(int(xpos)) + " | Y:" + str(int(ypos)), 1, (255, 0, 0))
    cam = FONT.render("Cam Perspective: " + str(cam_perspective), 1, (255, 0, 0))
    WINDOW.blit(coords, (0, 0))
    WINDOW.blit(cam, (0, 24))
    pygame.display.update()

赋予该函数的变量只是玩家的坐标以及摄像机视角。

我尝试通过复制 cam perspective 1 的代码并进行一些调整来解决问题，但这种方法没有奏效。我还尝试调整 x_tot/y_tot 以及 x_edge_coords/y_edge_coords，但这并没有解决问题，只是让放大和缩小变得几乎不可能。
