漫游时随机移动图片框

Question

[我想使用可以在不影响其运动的情况下随机漫游的PictureBox制作AI，例如：PictureBox必须执行向右移动的动作，如果计时器用尽，则下一个动作将向下移动，就像它漫游的随机度一样。

我以为可以对它进行硬编码。但是可能要花很长时间，而且一旦计时器停止，就不会再次重启。 idk为什么。

Here's a Picture of my Game so you would have some ideas about it.

这里也是代码

 private void Game_Load(object sender, EventArgs e)
    {
        E_Right.Start();
        if(Upcount == 0)
        {
            E_Right.Start();
        }
    }

    private void E_Right_Tick(object sender, EventArgs e)
    {
        if(Rightcount > 0)
        {
            EnemyTank.Left += 5;
            EnemyTank.BackgroundImage = Properties.Resources.EnemyTank_RIGHT_v_2;
            Rightcount = Rightcount - 1;
        }
        if (Rightcount == 0)
        {
            E_Right.Stop();
            E_Down.Start();
        }
    }

    private void E_Up_Tick(object sender, EventArgs e)
    {
        if (Upcount > 0)
        {
            EnemyTank.Top -= 5;
            EnemyTank.BackgroundImage = Properties.Resources.EnemyTank_TOP_v_1;
            Upcount = Upcount - 1;
        }
        if (Upcount == 0)
        {
            E_Up.Stop();
            E_Right.Start();
        }
    }

    private void E_Down_Tick(object sender, EventArgs e)
    {
        if (Downcount > 0)
        {
            EnemyTank.Top += 5;
            EnemyTank.BackgroundImage = Properties.Resources.EnemyTank_DOWN_v_1;
            Downcount = Downcount - 1;
        }
        if (Downcount == 0)
        {
            E_Down.Stop();
            E_Left.Start();
        }
    }

    private void E_Left_Tick(object sender, EventArgs e)
    {
        if (Leftcount > 0)
        {
            EnemyTank.Left -= 5;
            EnemyTank.BackgroundImage = Properties.Resources.EnemyTank_LEFT_v_1;
            Leftcount = Leftcount - 1;
        }
        if (Leftcount == 0)
        {
            E_Left.Stop();
            E_Up.Start();
        }
    }

假设PictureBox位于Location（0,0）。如果您看到一个PictureBox，则坦克的图像就没关系了。这将用于用户的MainTank。

您只需一个计时器就可以完成：

int moveToX = 0;
int moveToY = 0;
int speed = 5;
Random rand = new Random();

void ChooseNextPosition() {
    // Move vertical or horizontal?
    if (r.Next(2) % 2 == 0) {
        moveToX = r.Next(-5, 5);
    }
    else {
        moveToY = r.Next(-5, 5);
    }
}

private void Game_Load(object sender, EventArgs e) {
    ChooseNextPosition();
    timer1.Start();
}

private void timer1Tick(object sender, EventArgs e) {
    if (moveToX != 0) {
        EnemyTank.Left += moveToX * speed;
        moveToX += moveToX > 0 ? -1 : 1;
    }
    if (moveToY != 0) {
        EnemyTank.Top += moveToY * speed;
        moveToY += moveToY > 0 ? -1 : 1;
    }
    if (moveToX == 0 && moveToY == 0) {
        ChooseNextPosition();
    }
}
