Modifying part of the path

#1

Hi Aron,

Thank you for your work, that I find amazing.

I use your project to improve my Unity skills, but unfortunately I am stuck for many days on a problem I cannot solve.

My goal is to allow the player to modify only a part of the path : when they click on a point of the green line, all the path after is deleted, and when they click again on the map, the path is calculated only from the last click.

Is it possible to do, and would you have any advice for achiving that ?

Thank you very much !

Hey,

I don’t know if there is an out of the box solution for this.
I think it’s easier for you to just generate multiple paths, based on players interaction, and combine them at the end.

Hi

You can get the list of points in the path using path.vectorPath (see https://arongranberg.com/astar/docs/callingpathfinding.html). If you have both the old path and the new path you should be able to combine those lists into a new one which contains the whole path.

If you later need an actual path object you could use https://arongranberg.com/astar/docs/abpath.html#FakePath
