python - 碰撞评估中的故障状况
问题描述
我真的是一个初学者，我正在寻找一个错误。这是“碰撞”方法中 Game 类中的一个条件。我需要检测导弹与敌人之间的碰撞。问题：当导弹与敌人处于同一坐标时，会检测到碰撞。但是，如果其中一个炮弹在 X 坐标之外，则直到敌人 X 坐标之外的炮弹消失在屏幕顶部边缘之外时才会检测到另一次碰撞。

解决方案
而不是一种方法，
def kolize(self):
#vyhodnocuje střet střely s enemies
x, y = 0, 0
pocet_enemies = len(enemies.enem_x)
pocet_shots = len(shot.x)
while y < pocet_shots:
while x < pocet_enemies:
if (shot.y[y] - 23 > enemies.enem_y[x] and shot.y[y] - 23 < enemies.enem_y[x] + 50) and (shot.x[y] >= enemies.enem_x[x]-50 and shot.x[y] <= enemies.enem_x[x]+50):
del shot.x[y]
del shot.y[y]
del enemies.enem_x[x]
del enemies.enem_y[x]
del enemies.enem_invader[x]
del enemies.enem_speed[x]
pocet_enemies -= 1
pocet_shots -= 1
self.sestreleno += 1
break
x += 1
y += 1
我不得不使用这种方法。
def kolize(self):
#vyhodnocuje střet střely s invaderem
myBreak = False
pocet_enemies = len(enemies.enem_x)
pocet_shots = len(shot.x)
for y in range(pocet_shots):
for x in range(pocet_enemies):
if (shot.y[y] - 23 > enemies.enem_y[x] and shot.y[y] - 23 < enemies.enem_y[x] + 50) and (shot.x[y]-23 >= enemies.enem_x[x]-50 and shot.x[y] <= enemies.enem_x[x]+27):
game.explosion(enemies.enem_x[x], enemies.enem_y[x]) # předání souřadnic výbuchu
game.delShots(y)
game.delEnem(x)
pocet_enemies -= 1
pocet_shots -= 1
self.sestreleno += 1
if spaceship.health < 50: spaceship.health += 1
myBreak = True
break
if myBreak == True:
myBreak = False
break
我需要有条件地跳出嵌套循环并跳出主循环。
