功能 / Features

  • 游戏对象
  • 鼠标与键盘
  • 游戏角色缩放与旋转

入门 / Get started

要进行游戏对象的逻辑更新, 你需要创建一个 Game 对象, 它用来承载所有的游戏对象(GameObject)

Game game = new Game();

接下来, 你可以向游戏中添加一个最简单的贴图:

Bitmap bmp;  // 假设这是我们要显示的贴图
game.AddSprite(new GameSprite()
    Sprite = bmp    // 为 GameSprite 赋贴图

为了在 WinForm 窗口中进行游戏渲染, 你需要一个 GamePanel, 将其拖动到窗口, 然后在指定其要渲染的游戏

void Load(object sender, EventArgs args)
    gamePanel.Game = game;    // 为 GamePanel 指定要渲染的游戏

要启动游戏逻辑更新循环以及渲染循环, 调用其方法即可:


使用 / Usage


实现复杂的功能, 你必须使用定义自己的类型, 继承 GameSprite 或者 GameText, 并重写相关方法.


class MoveRightForever : GameSprite
    public float Speed { get; set; } = 1f;
    public override void Update()
        // SizeF 表示位移, 乘以 Game.DeltaTime 以使其速度不受帧率变化所影响
        Position += new SizeF(Speed, 0) * Game.DeltaTime;


GameSprite 包含默认的简单的碰撞检测, 它基于多边形的碰撞检测.

通过 Game 类的静态 IsCollided 方法来判断两个游戏对象是否碰撞

Game.IsCollided(a, b)

你可以自定义游戏对象的碰撞器多边形, 只需要为其 Collider 属性赋值即可

gameSprite.Collider = new GameObjectCollider(
    new PointF(.25f, .25f),          // 多边形顶点坐标 (0,0 为左上角, 1,1 为右下角)
    new PointF(.75f, .25f),
    new PointF(.75f, .75f),
    new PointF(.75f, .25f));


通过变换 Sprite 的值, 来实现简单的动画

class Warplane : GameSprite
    Bitmap[] bodies;
    public Warplane(Bitmap[] bodies)
        this.bodies = bodies;
    private async void SpriteChangeLoop()
        while (true)
            foreach (var me in bodies)
                await Task.Delay(100);
                Sprite = me;
