Question

所以我现在正在尝试为小班制作游戏小行星。问题是，自从我上次上课以来几乎没有做过任何编码，大约每年的3/4，并且几乎忘记了我所学到的一切。我需要使用推力/加速度来移动船，但也要盖上它，并且有摩擦力，这样当推力停止时，船会减速而不是立即停止。我有下面的基本数学用于旋转和加速船。我非常清楚编程正在将问题分解为简单的步骤，问题出现在这里，我不知道下一步该去哪里。任何帮助将不胜感激。

    // Ship's starting position
    static double positionX = 500.0;
    static double positionY = 500.0;
    // Calculate ship heading vectors based on current orientation in Radians
    static double orientationInRadians;
    static double xVector = Math.Sin(orientationInRadians);
    static double yVector = Math.Cos(orientationInRadians);
    /*Use Left and Right arrows to rotate
     Once vector is found,
     calculate position of ship 10 units away from current position along heading vector
     scale vector to a unit (length of 1) vector*/
    static double magnitude = Math.Sqrt(xVector * xVector + yVector * yVector);
    static double unitVectorX = xVector / magnitude;
    static double unitVectorY = yVector / magnitude;
    /*Now that the vector is one unit long
    but still points in the ships current orientation
    move ship with positionX and positionY as its current coordinates*/
    static double distanceToTravel = 10.0;
    double newPositionX = positionX + unitVectorX * distanceToTravel;
    double newPositionY = positionY + unitVectorY * distanceToTravel;
    /*Remember to track the ship's current position with a double or float
    and make distanceToTravel non-constant for acceleration instead of "jumps"*/

编辑：我忘了提及，这是我唯一的代码。所以我基本上坚持使用引擎来移动没有任何动静的东西。

Answer 1

嗯，你真的没有走得太远但是你可以在codeproject.com上学习很多完整的C＃实现：
