Xna 触摸定位

我正在做一个泡泡纸游戏。你按下泡泡使其破裂，然后在一点之后将其解开。一切都很好，泡泡会像计划的那样爆裂和消失。但有一个问题。每当我点击并拖动时，气泡仍然会弹出。有没有办法让它们在我点击并拖动时不会弹出？这是我的触摸位置代码

foreach (TouchLocation tl in touches)
            {
                if (tl.State == TouchLocationState.Pressed)
                {
                    if (rectangle.Contains((int)tl.Position.X, (int)tl.Position.Y))
                    {
                        popLocationX = (int)tl.Position.X;
                        popLocationY = (int)tl.Position.Y;
                    }
                }
            }

我还没有使用过touch，但是所有输入方法的逻辑应该是相似的

我将创建一个变量来存储旧的TouchLocationState。这样，您就可以检查用户是否正在单击和拖动。例如：

//TODO: instantiate this
TouchLocationState oldTLState; 

...

// This condition will only be true when the user clicks once, dragging will return false as the oldTLSTate is not released
if (tl.State == TouchLocationState.Pressed && oldTLState.State == TouchLocationState.Released)
{
    if (rectangle.Contains((int)tl.Position.X, (int)tl.Position.Y))
    {
        popLocationX = (int)tl.Position.X;
        popLocationY = (int)tl.Position.Y;
    }
}

//At the end of the Update() method, update oldTLState with the current state
oldTLState = tl;

这就是我所做的，我在我的主菜单上使用这个，但应该能够转换过来

加入以下内容：

    MouseState mouse;
    public float mouseDelay = 0.01f;
    public float mouseTime = 0.0f;
    public bool mouseActive = true;
    public bool mouseUsed = false;
    public string mouseOn = "None";
    public Vector2 mouseLocation;

• 鼠标有助于找到鼠标的位置
• 当鼠标处于按下位置时，鼠标播放将停止重复
• mouseTime会说嘿，如果我比mouseDelay大，鼠标可以再次使用
• mouseActive将显示是否按下。如果按下鼠标，则mouseActive为false
• 用鼠标将查看是否使用过它。如果鼠标除了背景之外没有点击任何东西，那么它将是错误的。如果是真的，那意味着它被用来做某事
• 鼠标在我的主菜单中被用来表示你按下了选项？制作

  mouseOn=“选项”并转到它

• 鼠标位置保留鼠标所在的位置

所有这些放在一起将有助于实现鼠标在按下时不被使用的目标

更新中：

    protected override void Update(GameTime gameTime)
    {
        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
            this.Exit();

        mouse = Mouse.GetState();

        if (this.IsMouseVisible == true)
        {
            MouseActive(gameTime);
        }
        base.Update(gameTime);
    }

当鼠标不在时，如果鼠标可见，可以阻止进程重复（处理能力降低）

记住这是为一个主菜单制作的，如果你想为一个游戏制作这个，你需要对它进行一些处理。

    void MouseActive(GameTime gameTime)
    {
        mouseTime += (float)gameTime.ElapsedGameTime.TotalSeconds;

        mouse = Mouse.GetState();

        mouseLocation = new Vector2(mouse.X, mouse.Y);

        switch (gameState)
        {
            case GameStates.TitleScreen:
                break;
            case GameStates.Options:
                break;
            case GameStates.Credits:
                break;
        }

        if (mouseOn != "None")
        {
            mouseUsed = true;

            switch (gameState)
            {
                case GameStates.TitleScreen:
                    if (mouseOn == "Play")
                    {
                    }
                    if (mouseOn == "Quit")
                        this.Exit();
                    if (mouseOn == "Options")
                        gameState = GameStates.Options;
                    if (mouseOn == "Title")
                    {
                    }
                    break;
                case GameStates.Options:
                    break;
                case GameStates.Credits:
                    break;
            }

            mouseOn = "None";
        }

        if (mouse.LeftButton == ButtonState.Pressed)
        {
            mouseTime = 0.0f;
            mouseActive = false;
        }

        if (mouse.LeftButton == ButtonState.Released && mouseTime > mouseDelay)
        {
            mouseActive = true;
            mouseUsed = false;
        }
    }

上面的所有代码都将在主类中

TitleScreen titlescreen;

    public Game1()
    {
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";

        titlescreen = new TitleScreen();
    }

    protected override void Initialize()
    {
        titlescreen.Initialize(this);

        base.Initialize();
    }

titlescreen.Update(gameTime);

这是一个名为

TitleScreen的类。cs

我是否使用了主类中TitleScreen和鼠标上的图像：

您首先需要初始化对象，因此在TitleScreen中添加此方法：

    Game1 game1;

    public void Initialize(Game1 game1)
    {
        this.game1 = game1;
    }

    public void Update(GameTime gameTime)
    {
        MouseState mouse = Mouse.GetState();

        if (mouse.LeftButton == ButtonState.Pressed && game1.mouseUsed == false && game1.mouseActive == true)
        {
            if (play.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Play";
                game1.mouseUsed = true;
            }
            else if (title.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Title";
                game1.mouseUsed = true;
            }
            else if (options.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Options";
                game1.mouseUsed = true;
            }
            else if (quit.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Quit";
                game1.mouseUsed = true;
            }
        }
    }

您需要在主类（Game1.cs）中添加初始值设定项。

然后在最后一步中，将更新添加到标题屏幕：

    Game1 game1;

    public void Initialize(Game1 game1)
    {
        this.game1 = game1;
    }

    public void Update(GameTime gameTime)
    {
        MouseState mouse = Mouse.GetState();

        if (mouse.LeftButton == ButtonState.Pressed && game1.mouseUsed == false && game1.mouseActive == true)
        {
            if (play.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Play";
                game1.mouseUsed = true;
            }
            else if (title.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Title";
                game1.mouseUsed = true;
            }
            else if (options.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Options";
                game1.mouseUsed = true;
            }
            else if (quit.Contains(mouse.X, mouse.Y))
            {
                game1.mouseOn = "Quit";
                game1.mouseUsed = true;
            }
        }
    }

您还需要将其添加到主类中的更新中

TitleScreen titlescreen;

    public Game1()
    {
        graphics = new GraphicsDeviceManager(this);
        Content.RootDirectory = "Content";

        titlescreen = new TitleScreen();
    }

    protected override void Initialize()
    {
        titlescreen.Initialize(this);

        base.Initialize();
    }

titlescreen.Update(gameTime);
