我正在做一个泡泡包装游戏。你按下气泡弹出它们然后稍微松开的那种。一切正常,气泡按计划弹出和发射。但有一个问题。每当我点击并拖动气泡仍然弹出。当我点击并拖动时,有没有办法让它们不弹出?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,但所有输入法的逻辑应该相似。

我会创建一个变量来存储旧的TouchLocationState。这样,您可以检查用户是否正在点击并拖动。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;

这是我的工作,我在主菜单上使用它,但应该可以转移。

将这些添加到:

    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,mouseDelay将停止重复。
  • mouseTime会说嘿,如果我大于mouseDelay鼠标可以再次使用。
  • mouseActive会说是否按下了。如果按下鼠标,则mouseActive为false。
  • mouseUsed将查看它是否曾被使用过。如果鼠标没有点击除背景之外的任何东西,那么它将是假的。如果为真,那意味着它被用来做某事。
  • mouseOn用于我的主菜单,说你按下选项?点击mouseOn = "Options";然后转到它。
  • mouseLocation保存鼠标所在的位置。

考虑到这一切,将所有这些放在一起将帮助您实现在按下鼠标时不使用鼠标的目标。

更新:

    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);
    }

如果鼠标不可见,鼠标可见,以便在鼠标不存在时停止重复进程(处理能力较低)。

请记住,这是针对主菜单制作的,如果你想为游戏制作这个游戏,你需要稍微弄清楚它。

    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

这是一个名为TitleScreen.cs的类,我使用TitlesScreen上的图像和主类中的鼠标:

首先需要初始化事物,所以在TitleScreen中添加此方法:

    Game1 game1;

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

您需要将一个初始化程序添加到Main类(Game1.cs)

TitleScreen titlescreen;

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

        titlescreen = new TitleScreen();
    }

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

        base.Initialize();
    }

然后,在最后一步中,将Update添加到TitleScreen:

    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
titlescreen.Update(gameTime);
