Navigation 'Is Partial' doesn't work
I have an AI using Navmesh navigation. When I try to see if it can reach a location it should not be able to reach (e.g. a closed room that has a Navmesh with the AI outside of the room) I do a check with 'Find Path To Location Synchronously' and take the Navigation Path Reference this returns to check for 'Is Partial'.
When making my AI move to that same location and checking 'Has Partial Path' it returns true. So the path it has to the target location is partial, even though 'Is Partial' tells us that same path is not partial.
I'm having issues with my AI behaviour because of this. I need a way to know if my AI can actually reach the target location before I make it move there. It's important to keep in mind that the unreachable location is actually on the Navmesh.
I ran into this issue while working in UE 4.15.3 and can't confirm if the same issue is present in 4.16.1.
Can anyone reproduce this issue and/or help me find a way to figure out if a Navmesh location is reachable for an AI before making it move there?
Thanks in advance,
