C# 二维碰撞检测系统在对角移动到拐角处时没有反应

因此，我的碰撞检测系统被设置为检查角色的每个像素，标记collisionDetected，将违规角色模型的像素放入collisionDetectedX和collisionDetectedY。它使用此数据确定有效的可移动区域的位置，并将装置推回到其中。解决这个问题的唯一方法是让X和Y的碰撞类同时运行，还是我可以修改这个类以正确地同时执行这两个作业？谢谢你抽出时间，我一直在发疯，想弄清楚我做错了什么。我为粗心的代码道歉。我把它清理了一点，真是一团糟，但我意识到它不值得最终产品

在原文中回答了我的问题。

也许这会有帮助：

        if (collisionDetected == true)
        {
            collisionDetectedX += Convert.ToInt16(position.X);
            collisionDetectedY += Convert.ToInt16(position.Y);
            if (background[collisionDetectedX, collisionDetectedY + 2] == Color.Red && collisionDetected)
            {
                position.Y += 1;
                collisionDetected = false;
            }
            if (background[collisionDetectedX, collisionDetectedY - 2] == Color.Red && collisionDetected)
            {
                position.Y -= 1;
                collisionDetected = false;
            }
            if (background[collisionDetectedX + 2, collisionDetectedY] == Color.Red && collisionDetected)
            {
                position.X += 1;
                collisionDetected = false;
            }
            if (background[collisionDetectedX - 2, collisionDetectedY] == Color.Red && collisionDetected)
            {
