C# 使变量正确递增的问题

我正在为我最后一年的项目制作一个教育游戏，当我的玩家框与另一个物品框发生碰撞时，我遇到了一个增加值的问题。当我的播放机死机后重新设置时，会出现错误，第一个项目收集得很好，但是程序似乎会跳过下一个if语句，并提取第三个项目，而不是第二个项目

我在下面添加了我认为存在问题的代码

LevelManager.cs

                for (int x = hints.Count - 1; x >= 0; x--)
            {
                hints[x].Update(gameTime);
                if (player.CollisionRectangle.Intersects(
                    hints[x].CollisionRectangle))
                {
                    hints.RemoveAt(x);
                    player.Hint++;
                }
            }

游戏1.cs

 if ((gameState == GameState.Playing) ||
            (gameState == GameState.PlayerDead) ||
            (gameState == GameState.GameOver))
        {
            spriteBatch.Begin(
          SpriteSortMode.BackToFront,
          BlendState.AlphaBlend);

            TileMap.Draw(spriteBatch);
            player.Draw(spriteBatch);
            LevelManager.Draw(spriteBatch);
            spriteBatch.DrawString(
                pericles8,
                "Score: " + player.Score.ToString(),
                scorePosition,
                Color.White);
            spriteBatch.DrawString(
                pericles8,
                "Lives Remaining: " + player.LivesRemaining.ToString(),
                livesPosition,
                Color.White);

            if (player.Hint == 1)
            {
                spriteBatch.DrawString(
                    pericles8,
                    "Hint: " + "Antivirus is needed to protect your PC",
                    HintLocation,
                    Color.Black);
            }

            if (player.Hint == 2)
            {
                spriteBatch.DrawString(
                    pericles8,
                    "Hint: " + "When the first virus was created, it changed the name of floppy disks that were infected",
                    HintLocation,
                    Color.Black);
            }

            if (player.Hint == 3)
            {
                spriteBatch.DrawString(
                    pericles8,
                    "Hint: " + "Blue Whale is NOT the name of a virus and also whilst adware is annoying, it is not considered a virus",
                    HintLocation,
                    Color.Black);
            }

            if (player.Hint == 4)
            {
                spriteBatch.DrawString(
                    pericles8,
                    "Hint: " + "By having a firewall up, you lock all backdoors into your PC." + "\n" + "Also by staying clear of sites you dont know, you lower the chance of viruses getting into your PC" + "\n"
                    + "However you should install relevant protection to increase your chance of not getting viruses",
                    HintLocation,
                    Color.Black);
            }
            spriteBatch.End();
        }

        if (gameState == GameState.PlayerDead)
        {
            player.Hint = 0;
        }

如能提供任何帮助，我们将不胜感激

干杯

我在您提供的代码片段中没有看到bug。我所能说的就是你可以在线路上设置断点

player.Hint++;

---

（或者更好地在提示属性的setter中设置事件）并查看它何时以及为什么更改为3。

这不是答案，应该是注释。玩家可能在同一循环中击中两个对象，因此它将增加两倍。尝试在

player.Hint++之后放置循环中断我已经从你的问题标题中删除了标签，因为大家的一致意见是否定的，它们不应该。不相关，但你似乎太相信防火墙了。
