c# - 在C#XNA游戏中用鼠标单击时移动图像

仅当通过鼠标单击图像时，才需要移动图像。

我有这个运动：

if (Mouse.GetState().LeftButton == ButtonState.Pressed &&
    previousMouseState.LeftButton != ButtonState.Pressed)
{
    xpos = rnd.Next(windowWidth - texture.Width);
    ypos = rnd.Next(windowHeight - texture.Height);
}

previousMouseState = Mouse.GetState();

但是我需要某种复合的if逻辑来使它仅在单击纹理时才移动。

最佳答案

我假设您的texture对象不仅仅是一个Texture2D。

绘制精灵时，您需要同时具有位置和大小。这样的事情应该起作用：

var currentMouseState = Mouse.GetState();

if (currentMouseState.LeftButton == ButtonState.Pressed &&
previousMouseState.LeftButton != ButtonState.Pressed)
{
    Vector2 mousePosition = new Vector2(currentMouseState.X,currentMouseState.Y);

    mousePosition-=sprite.Position;

    /// .Bounds is a property of Texture2D, and returns a Rectangle() struct
    var spriteWasClicked = sprite.Bounds.Contains(mousePosition.X,mousePosition.Y);

    if(spriteWasClicked)
    {
        xpos = rnd.Next(windowWidth - texture.Width);
        ypos = rnd.Next(windowHeight - texture.Height);

        // update sprite position with to xpos,ypos here.
    }

}

previousMouseState = currentMouseState;
