本文介绍了射击。与列表碰撞的镜头的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我出于学习目的而制作了一个太空入侵者克隆。入侵者被枪杀后，我一直陷在这个问题上。我不确定子弹与侵略者（位置列表）的一部分发生碰撞时如何擦除它以及游戏是否继续。有人知道吗？

解决方案
我没有声称要对您的设计进行重做，而是向其中添加了死亡侵略者（ ArmyOfInvaders.deadInvader ）的集合。存储那些已经射击的人，并更改了 InvaderGotShot 和 DrawItem 方法。我摆脱了 Invader.invader 集合，并在 Invader.InitializeInvader 中引入了局部变量，而不是为了防止分配错误。请看一下：

{
stepCount ++;

ArmyOfInvaders.armyOfInvaders.Clear（）;
ArmyOfInvaders.InitializeArmyOfInvaders（Movement.moveY，Movement.moveX）;

stepCount = 0;
}
Console.CursorVisible = false;
Draw.DrawItem（ArmyOfInvaders.armyOfInvaders）;
Draw.EraseItem（Player.player）;
Shoot.GenerateShot（）;
Movement.MovementPlayer（）;

重点是向用户隐藏死去的外星人，而不是将其排除在外采集。您的实现尝试清除被射击外星人的位置，但是在下一次迭代中，它再次初始化了所有入侵者。
还请注意，我被迫引入文字 Movement.MovementArmyOfInvaders 中的> 9 ，而不是调用 Invader.invader.Length 。
希望有帮助。
I'm making for learning purpose a space invaders clone. I'm stuck on the issue when an invader got shot. I'm not sure when there is a collision of a bullet with a part of the invader(who is a list of positions) how to erase it and the game to continue. Has anyone got an idea?

Without claiming to rework your design, I added collection of dead invaders(ArmyOfInvaders.deadInvader) to stored those ones, who already shot, and changed InvaderGotShot and DrawItem methods. I got rid of Invader.invader collection and introduced local variable in Invader.InitializeInvader instead of it to prevent misassigning. Please take a look:
class Program
{
static void Main()
{
Settings.ScreenSettings();
ArmyOfInvaders.InitializeArmyOfInvaders();
Player.InitializePlayer();
int stepCount = 0;
int armyOfInvadersSpeed = 50;
while (true)
{
stepCount++;
if (stepCount % armyOfInvadersSpeed == 0)
{
Draw.EraseItem(ArmyOfInvaders.armyOfInvaders);
ArmyOfInvaders.armyOfInvaders.Clear();
ArmyOfInvaders.InitializeArmyOfInvaders(Movement.moveY, Movement.moveX);
Movement.MovementArmyOfInvaders();
stepCount = 0;
}
Console.CursorVisible = false;
Draw.DrawItem(ArmyOfInvaders.armyOfInvaders);
Draw.EraseItem(Player.player);
Shoot.GenerateShot();
Movement.MovementPlayer();
Draw.DrawItem(Player.player);
Draw.DrawShoot();
Draw.EraseShoot();
Collision.InvaderGotShot();
Thread.Sleep(Common.gameSpeed);
}
}
}

The point was to hide dead aliens from user, but not to exclude them from collection. Your implementatiion tried to clear positions of shot alien, but on the next iteration it initialized all invaders again.
Also notice that I was forced to introduce literal 9 in Movement.MovementArmyOfInvaders instead of call Invader.invader.Length.
Hope it helps.
