Unity Route Drawing Tool

In the production of the NPC car's route, put point----and put into the array--draw line, each point into the array is a waste of time, so I consider to put all the points in a parent, in order to Edito mode, the dynamic acquisition of all point information, and then draw the route.

I use the Enable state of the script to control the acquisition of array elements.
