在pygam中有没有一种方法可以blit多个图像或一个图像列表

Question

这一天我已经找了无数的帖子。我试图弄清楚如何让我的精灵执行攻击动画，但实际上没有文件或信息，我可以找到有关如何在网上做这件事。我已经把它带到了他将执行旋转攻击动画的地方，如果我向右移动，但是在旋转了这么多次之后，游戏会崩溃并说“列表索引超出范围”。此外，如果角色静止不动，按攻击键“w”完全没有任何作用。我已经包括了我的代码副本。任何帮助都将不胜感激。在

Answer 1

每当增加索引时，必须确保索引不会溢出可用的图像数。您这样做是为了walkCount，而不是为了attackCount。在

如注释中所示，modulo operator%很方便。在

因此，您可以在中更改重绘功能：

def redrawGameWindow():
    global walkCount
    global attackCount
    screen.blit(bg, (0,0))

    if left:
        screen.blit(walkLeft[walkCount//3], (x,y))
        walkCount += 1
        walkCount %= len(walkLeft)
        attackCount += 1
        attackCount %= len(spinAttackList)

    elif right:
        screen.blit(walkRight[walkCount//3], (x,y))
        walkCount += 1
        walkCount %= len(walkRight)
        attackCount += 1
        attackCount %= len(spinAttackList)
    else:
        screen.blit(char, (x,y))

    if spin:
        screen.blit(spinAttackList[attackCount//3], (x,y))

    pygame.display.update()

我不知道您为什么要使用整型除法运算符//，我已经不说了，但是我想您可能是想使用%，在这种情况下，后续的%=行就不必要了。在

如果你想要更优雅的东西，你可以使用cycling iterator。在

检查一下我已经做过了

def drop_enemies(enemy_list):
delay = random.random()
if len(enemy_list) < 10 and delay < 0.1:
    x_pos = random.randint(0, WIDTH - enemy_size)
    y_pos = 0
    enemy_list.append([x_pos, y_pos])


def draw_enemies(enemy_list):
for enemy_pos in enemy_list:
    pygame.draw.rect(screen, BLUE, (enemy_pos[0], enemy_pos[1], enemy_size, enemy_size))
