Given the abstraction, the notion of a point as an instance with some values, I can now start building segments.
真的很有帮助,基于这个抽象,点的概念也就是一个,有一些值的实例。
And then from that start point, get the x-value. Same thing, from that instance, get the endpoint, from that end point get the x-value, square.
取得结束点,然后取得结束点的y坐标,然后求差开平方,然后同样求的y坐标。
It says if I want to get the length of a segment, going to pass in that instance, it says from that instance, get the start point, that's the thing I just found.
它的意思是如果我想要,得到一个线段的长度,首先要把这个实例传进来,然后对于这个实例,从开始点,取得x坐标,然后通过同样的操作。
