Family LoS obstacles are applied gobally

I'm necroing this thread cause it's locked: https://www.construct.net/en/forum/construct-3/how-do-i-8/two-objects-pathfinding-not-138879

If you add a pathfinding / Los obstacle to a specific instance of a family, that obstacle will be added to all members of the family. So it's not possible to have the same LoS behavior have different obstacles among instances.

This is annoying because I want certain objects under a family to have different obstacles. (e.g. crawling enemies can't go up stairs).

A work around is to have a second LoS behavior which you only call after checking the family LoS, if enabled for that type. I get the performance, but this does feel like a bug. You wouldn't need different maps for every objects, just every variation of obstacles.

Just an FYI. So stuff like this would actually apply to all NPCs, breaking their LoS behaviors.

You use Families when something applies to all object types within the Family. If you want objects in the Family to do different things then you pick the individual object types. It only makes sense to use LOS at the Family level if all object types within act the same way.

you need a family of crawling things.

Thanks for the suggestions, but I've already found a work around. I mostly just made this post for discussion cause I found it unexpected.

Also this isn't specifically for families, that was bad labeling on my part. It's any instance.
