机器人追踪计划？ [英] Robot Tracking Program?

问题描述

大家好，我很抱歉我不知道应该在哪里发布这个特别的东西...... :(反正，

Hello all, I'm sorry I have no idea where I should of posted this particular thing... :( anyways,

我正在尝试制作一个简单的跟踪程序而且我不知道应该从哪里开始。我之前使用过它而且它是mega在很多方面很有帮助。

I am trying to make a simple tracking program and I am at a loss of where I should begin. I've used this before and it was mega helpful in a lot of ways.

到目前为止我所做的是形式，但从那时起我感到很茫然基本上它是一个带有N，S，E和W按钮以及坐标l的程序abel显示当前坐标，它从{X = 0，Y = 0}开始，然后它们也是Go 1按钮和Go 10按钮
所以它的功能如下：

What I have so far is the form made but from that point I'm at a loss. Basically it is a program with N, S, E, and W button and a Coordinate label that displays the current coordinate it starts at {X=0, Y=0} then their is also a Go 1 button and a Go 10 button so how it functions is like first:

我点击让我们说E（东）按钮>

I click the lets say the E (East) Button >

然后我点击Go 10按钮>

Then I click the Go 10 button >

标签将更改为{X = 10，Y = 0}。

The label will change to {X=10, Y=0}.

所述示例的延续将是：

A continuation of said example would be:

然后我点击S（南）>

I then click S (South) >

后跟Go 1>

Followed by Go 1 >

然后标签为{X = 10，Y = -1} ......

The label would then be {X=10, Y=-1}...

希望这是有道理的，但这正是我目前正在努力实现的目标。

Hopefully that makes sense but that's what I am currently trying to achieve.

推荐答案

我会在内部存储机器人的方向。你最好将这个方向表示为一对数字，代表"Go 1"对你的位置会做什么你从0,0开始。（这被称为"方向向量"）

I'd store the direction of the robot internally.  You'll be best served to represent the direction as a pair of numbers that represent what a "Go 1" would do to your position if you started at 0,0. (This is called a "direction vector")

例如，如果你点击"W"面朝西，你可以更新你的方向向量，如下所示：

For example, if you click 'W' to face west you might update your direction vector like this:

directionX = -1;

directionY = 0;

directionX = -1;
directionY = 0;

将此技术适当地应用于其他基数方向处理程序。

Apply this technique appropriately for the other cardinal direction handlers.

Go 1会这样做：

positionX + = directionX;

positionY + = directionY;

positionX += directionX;
positionY += directionY;

和Go 10会这样做：

and Go 10 would do:

positionX + = directionX * 10;

positionY + = directionY * 10;

positionX += directionX * 10;
positionY += directionY * 10;

您可以决定North是+ Y还是-Y。

You can decide whether North is +Y or -Y.

如果North是posit依维尔，然后"面向北方"。会做：

If North is positive Y, then "face north" would do:

directionX = 0;

directionY = 1;

directionX = 0;
directionY = 1;
