开始根据另一个图片框位置移动图片框 [英] Start moving the picturebox based on another picturebox location

问题描述

我正在尝试移动图片框，但我想让其他图片框出现或者只在图片盒1到达特定位置后才开始移动。我正在使用计时器让它移动。我是新手，请理解:(



我尝试过：



private void timer1_Tick（object sender，EventArgs e）

{

picbox2.Left - = 5;

lbl2.Left - = 5;



if（picbox2.Left == 1245）//它的起始点是（1367,110）

{

lbl1.Left - = 5;

picbox1.Left - = 5;

}

}

I'm trying to move a picturebox but i want the other picturebox to appear or to start moving only after the picturebox1 gets to a specific location. Im using a timer to make it move. I am new to this thing, please understand :(

What I have tried:

private void timer1_Tick(object sender, EventArgs e)
{
picbox2.Left -= 5;
lbl2.Left -= 5;

if (picbox2.Left == 1245)//its staring point is (1367, 110)
{
lbl1.Left -= 5;
picbox1.Left -= 5;
}
}

推荐答案

如果它的起始位置是（1367,100），并且每次从它减去5，那么它将永远不会达到（1245，y）：x坐标将永远以2或7结束，从不结束5.

我建议的是：

If it's starting location is (1367, 100), and you subtract 5 from it each time, then it will never reach (1245, y) at all: the x coordinate will always end in a 2 or a 7, never a 5.
What I'd suggest is :

if (picbox2.Left <= 1245)
   {
   ...
   }

就这样，它会当它到达那里时，它会移动，并从那一点开始继续移动。

That way, it will start moving when it gets there, and continue moving from that point.
