Help How to generate rope from one point to next points ?

[webmagic]

Hi , let’s say we have 3 point in the scene (attached), how to generate rope from point 1 to point 2, and continue from point 2 to point 3? In runtime.

For example, there are some balls in the scene, when I press the button, a rope generated through these three points by order(like: 1~2~3~4~5….)
