英文:
How to set an objects rotation to follow a line in unity?
问题
我有两个向量形成一条线，我想将物体放置在其中一个向量上，并使其旋转以跟随这个角度。
我尝试了Unity中大部分我能找到的函数，但始终无法正确实现。
英文:
I have 2 vectors that form a line and I want to place the object at one of the vectors, with a rotation that follows this angle.
I have tried using most of the functions in unity that I can find but cannot get it right at all.

你可以使用Quaternion.LookRotation来计算旋转。只需为两点之间的向量和一个“上方向”（可能是Vector3.up）提供参数。
var rotation = Quaternion.LookRotation(p1 - p2, Vector3.up);
或者，由于Vector3.up已经是默认值
var rotation = Quaternion.LookRotation(p1 - p2);
英文:
You should be able to use Quaternion.LookRotation to compute a rotation. Just give it a vector for the vector between the two points, and a "up-direction", probably Vector3.up.
var rotation = Quaternion.LookRotation(p1 - p2, Vector3.up);
or - since Vector3.up is the default value anyway
var rotation = Quaternion.LookRotation(p1 - p2);

以上帝之名。以下命令将解决您的问题。
transform.position = v1;
transform.forward = (v2 - v1).normalized;
英文:
in the name of God. The following command will solve your problem.
transform.position = v1;
transform.forward = (v2 - v1).normalized;
