c＃问题？ [英] c# question ?

问题描述

喜。我需要一些大约2平方的代码和他们彼此之间的意外。首先，我需要有关于点和线的类的代码。然后用''''如果''''方法我应该将两个方块相互组合并理解事故点的位置。

hi. i need some codes about 2 square and the accidents that they have with each other.first of all, i need to have codes about a class for point and line. then with ''''if'''' method i should combine two square with each other and understand the position of the accident''s points.

推荐答案

I相信你所指的是碰撞检测。



这个 [ ^ <来自MSDN的小教程可以帮助你。



我在Q& A中也发现了这个问题你可以参考：如何分析矩形是否与另一个矩形重叠 [ ^ ]

I believe what you are referring to is called "Collision Detection".

This[^] small tutorial from MSDN may help you along your way.

I also found this question in Q&A you can refer to: how to analyze whether a rectangle is overlap another rectangle[^]
