我的跳转按钮不起作用？ [英] My jump button won't work?

问题描述

大家好，



我在XNA C＃中创建游戏，我目前正在创建跳转功能。但由于某些原因它不起作用？



按下W时触发我的Jump（）。我的Gravity（）每秒触发约55次。 br $> b $ b

Hello everyone,

I am creating a game in XNA C#, and I am currently creating the jump function. But for some reason it won't work?

My Jump() is triggered when pressed W. And my Gravity() is triggered about 55 times a second.

/* Is the player jumping? */
public bool Jumping = true;

public void Jump()
{
    if (Jumping == false)
    {
        Jumping = true;

        for (int i = 0; i < 8; i++)
        {
            if (!Colliding(0, i))
            {
                this.PositionPixelY -= i;
                CalculatePositions();
            }
        }
    }
}

public void Gravity()
{
    if (!Colliding(0, MovingSpeed) && !Jumping)
    {
        this.PositionPixelY += MovingSpeed;
        CalculatePositions();
    }
    if(Colliding(0, MovingSpeed))
    {
       Jumping = false;
    }
}

编辑：此外，当我的角色陷入困境时，我跳的是什么没有重力拉下来。对不起，我总是忘记说出了什么问题。

Also, what happens is, when I jump once my character gets stuck with no gravity pulling it down. Sorry I always forget to say what goes wrong.

推荐答案

好吧我遇到的问题是，一旦我们跳了就不会失败。

这是正常的，因为我只是告诉它一旦我们不再跳跃就会失败。

然而，一旦我们到达地面，我们就不会跳跃。一个简单的解决方案是添加第二个布尔值，如下所示：

Okay the problem I was having is that it won't go down once we jumped.
This is normal because I am only telling it to go down once we're no longer jumping.
However, we won't be jumping once we reached the ground. A simple solution would be adding a second boolean like so:

public void Jump()
{
    if (Jumping == false)
    {
        GravityBool = false;
        Jumping = true;

        for (int i = 0; i < 8; i++)
        {
            if (!Colliding(0, -i))
            {
                this.PositionPixelY -= i;
                CalculatePositions();
            }
        }

        GravityBool = true;
    }
}

public void Gravity()
{
    if (!Colliding(0, MovingSpeed) && GravityBool)
    {
        this.PositionPixelY += MovingSpeed;
        CalculatePositions();
    }
    else
    {
        Jumping = false;
    }
}

再次感谢Codeproject让我的想法通过上传这个问题来节省一些时间，我稍后将其整理出来。

Thanks Codeproject once again for letting my mind having a bit of peace by uploading this problem, and I sorted it out a bit later.
