Как я могу совершить более одного действия с одним набором кода?

Question

Если мой корабль стреляет 10 пулями, мне нужно нарисовать 10 пуль на экран. Могу ли я нарисовать 10 таких же предметов на экране, не имея патрона кода для каждого из них и только один кусок кода?

Например, вот все за 10 пуль:

Могу ли я использовать один кусок кода, и список или что-то? Если у кого-то есть идея, я все уши.

Answer 1

У меня тоже была эта проблема. Вам нужен список. Вот бы пример: Bullets = [[BulletX,BulletY,BulletDirection],[BulletX,BulletY,BulletDirection]] Чтобы добавить пулю в список, вы можете сделать:

Bullets.append([BulletX,BulletY,BulletDirection])

Для их отображения используется:

for Bullet in Bullets: BulletX = Bullet[0] BulletY = Bullet[1] BulletDIrection = Bullet[2] (PutYourSurfaceHere).blit(BulletImage,(BulletX,BulletY)

Если вы Ждут» t know, for - это цикл, который в основном означает: для каждой Bullet in Bullets: выполните следующие действия. Кроме того, BulletX = Bullet[0] устанавливает переменную BulletX в первую часть списка Bullet. В списке bullet есть списки внутри него. Каждый список внутри Bullets - это «пуля». С помощью цикла вы просто получаете доступ к данным Bullet. Кроме того, Bullet[1] обращается ко второй части списка этой конкретной пули. (потому что он подсчитывается от 0). Тогда вы просто blitting изображение пули в ее местоположении. Чтобы переместить его, вы можете сделать Bullet[0] += 5. (Это переместит его вправо на 5 пикселей.)

Чтобы удалить пулю, просто введите петлю Bullets.remove(Bullet). Это приведет к удалению пули из списка, который он обрабатывает.

Если вы не можете понять это, просто перейдите по ссылке google list и loop tutorial для python. (Google их отдельно.)

Answer 2

Вот два хороших учебника, которые помогут вам узнать, как использовать список и list.pop().
