c# - c# - 如何使用Loop来验证一个对象是否在c#WF中与另一个对象Bounds绑定Intersets？

问题描述

我如何将这一系列 if 转换为循环？

我正在制作Windows形式的2D游戏，我想检查5颗子弹中的一颗是否击中了5个敌人中的一个，但我想知道哪个子弹击中了哪个敌人！（我知道如何做到这一点的逻辑，但我只想用循环而不是用 25 if 来做）谢谢！

if (bulletOne.Bounds.IntersectsWith(enemyOne.Bounds) || bulletTwo.Bounds.IntersectsWith(enemyOne.Bounds) || bulletThree.Bounds.IntersectsWith(enemyOne.Bounds) || bulletFour.Bounds.IntersectsWith(enemyOne.Bounds) || bulletFive.Bounds.IntersectsWith(enemyOne.Bounds))
{
    enemyOne.Left = rnd.Next(1300, 1400);
}
if (bulletOne.Bounds.IntersectsWith(enemyTwo.Bounds) || bulletTwo.Bounds.IntersectsWith(enemyTwo.Bounds) || bulletThree.Bounds.IntersectsWith(enemyTwo.Bounds) || bulletFour.Bounds.IntersectsWith(enemyTwo.Bounds) || bulletFive.Bounds.IntersectsWith(enemyTwo.Bounds))
{
    enemyTwo.Left = rnd.Next(1300, 1400);
}
if (bulletOne.Bounds.IntersectsWith(enemyThree.Bounds) || bulletTwo.Bounds.IntersectsWith(enemyThree.Bounds) || bulletThree.Bounds.IntersectsWith(enemyThree.Bounds) || bulletFour.Bounds.IntersectsWith(enemyThree.Bounds) || bulletFive.Bounds.IntersectsWith(enemyThree.Bounds))
{
    enemyThree.Left = rnd.Next(1300, 1400);
}
if (bulletOne.Bounds.IntersectsWith(enemyFour.Bounds) || bulletTwo.Bounds.IntersectsWith(enemyFour.Bounds) || bulletThree.Bounds.IntersectsWith(enemyFour.Bounds) || bulletFour.Bounds.IntersectsWith(enemyFour.Bounds) || bulletFive.Bounds.IntersectsWith(enemyFour.Bounds))
{
    enemyFour.Left = rnd.Next(1300, 1400);
}
if (bulletOne.Bounds.IntersectsWith(enemyFive.Bounds) || bulletTwo.Bounds.IntersectsWith(enemyFive.Bounds) || bulletThree.Bounds.IntersectsWith(enemyFive.Bounds) || bulletFour.Bounds.IntersectsWith(enemyFive.Bounds) || bulletFive.Bounds.IntersectsWith(enemyFive.Bounds))
{
    enemyFive.Left = rnd.Next(1300, 1400);
}

解决方案

尝试将子弹和敌人放在一个列表中，然后循环遍历该列表。这样，您可以让所有子弹在一个循环中检查所有敌人。

但是为了把它们放在一个列表中，你应该使用类，这样你就可以用它们制作一个对象，多次调用它们。

例如：

//note: 'Enemy' and 'Bullet' are class names, so they'll need to be defined in a seperate class
List<Enemy> enemies = new List<Enemy>();
List<Bullet> bullets = new List<Bullet>();

//fill your lists in the way you want them to spawn, example below:
bullets.Add(new Bullet(/*place your bullet variables here*/));
enemies.Add(new Enemy(/*place your enemy variables here*/));

//loop
foreach (Bullet b in bullets)
{
    foreach (Enemy e in enemies)
    {
        if (b.Bounds.IntersectsWith(e))
        {
            e.Left = rnd.Next(1300, 1400);
        }
    }
}
