我一直在尝试解决这个问题，但我真的看不出代码有什么问题。它与我的其他矩形完全相同，但它不起作用。

工作代码：这里的一切工作正常（或多或少）

private void UpdateCollision()
    {
        // Uses built in rectangle intersect function to determine overlapping
        Rectangle rectangle1;
        Rectangle rectangle2;
        Rectangle rectangle3;

        // Creates 1 rectangle for player
        rectangle1 = new Rectangle((int)player.Position.X, (int)player.Position.Y, player.Width, player.Height);

        // Sets collision btw objs
        for (int i = 0; i < enemies.Count; i++)
        {
            for (int j = 0; j < enemies2.Count; j++)
            {
                rectangle2 = new Rectangle((int)enemies[i].Position.X, (int)enemies[i].Position.Y, enemies[i].Width, enemies[i].Height);
                rectangle3 = new Rectangle((int)enemies2[j].Position.X, (int)enemies2[j].Position.Y, enemies2[j].Width, enemies2[j].Height);

                // Determines collision
                if (IntersectPixels(rectangle1, playerTextureData, rectangle2, enemyTextureData) && player.PlayerAnimation.Active == true)
                {
                    player.Health -= enemies[i].Damage;
                    enemies[i].Health = 0;

                    if (player.Health == 0)
                        AddMyExplosion(player.Position);
                }

                if (IntersectPixels(rectangle1, playerTextureData, rectangle3, enemy2TextureData) && player.PlayerAnimation.Active == true)
                {
                    player.Health -= enemies2[j].Damage;
                    enemies2[j].Health = 0;

                    if (player.Health == 0)
                        AddMyExplosion(player.Position);
                }
            }
        }

非工作代码：弹出异常的行是定义rectangle3的地方

// Proj obj collision
        for (int i = 0; i < projectiles.Count; i++)
        {

            for (int j = 0; j < enemies.Count; j++)
            {
                for (int k = 0; k < enemies2.Count; k++)
                {

                    // Creates col det rectangles
                    rectangle1 = new Rectangle((int)projectiles[i].Position.X - projectiles[i].Width / 2, (int)projectiles[i].Position.Y - projectiles[i].Height / 2, projectiles[i].Width, projectiles[i].Height);
                    rectangle2 = new Rectangle((int)enemies[j].Position.X - enemies[j].Width / 2, (int)enemies[j].Position.Y - enemies[j].Height / 2, enemies[j].Width, enemies[j].Height);
                    rectangle3 = new Rectangle((int)enemies2[k].Position.X - enemies2[k].Width / 2, (int)enemies[k].Position.Y - enemies2[k].Height / 2, enemies2[k].Width, enemies2[k].Height);
                    //Rectangle 3 is not working//

                    // Determines col
                    if (IntersectPixels(rectangle1, projectileTextureData, rectangle2, enemyTextureData))
                    {
                        enemies[j].Health -= projectiles[i].Damage;
                        AddImpact(projectiles[i].Position);
                        impactSound.Play();
                        projectiles[i].Active = false;
                    }

                    if (IntersectPixels(rectangle1, projectileTextureData, rectangle3, enemy2TextureData))
                    {
                        enemies2[j].Health -= projectiles[i].Damage;
                        AddImpact(projectiles[i].Position);
                        impactSound.Play();
                        projectiles[i].Active = false;
                    }
                }
            }
        }
    }

因此，如果有人可以帮助我解决这个问题，我将不胜感激。

错字。更改此行：

rectangle3 = new Rectangle((int)enemies2[k].Position.X - enemies2[k].Width / 2, (int)enemies[k].Position.Y - enemies2[k].Height / 2, enemies2[k].Width, enemies2[k].Height);

对此：

rectangle3 = new Rectangle((int)enemies2[k].Position.X - enemies2[k].Width / 2, (int)enemies2[k].Position.Y - enemies2[k].Height / 2, enemies2[k].Width, enemies2[k].Height);
