Freaky Line of Sight ¿Bug? in dungeon crawler

I´m working on a checkered grid dungeon crawler, and while working with a Ranged unit, that should only attack while aligned with the player (think of it as a Ranged Rook) when I check LineOfSigth in the 90° it doesn´t detect it, it does work with every other angle thought, I tried trouble-shooting it by removing everything else but it still gives trouble with that angle, any ideas what I might be doing wrong?

I´ll leave some caps:

as you can see, all enemies attack expect the one straight down

(angle of sigth is only used for LOS, and angle of movement marks the moving direction

I would like to help but upload the file to dropbox or google drive first. Don't forget to grant/open access later.

thanks alextro

I´m still kind of new to participating in forums and don't have all the proper "etiquette" ,next time I´ll just post the project :)

I removed a lot of functions and behaviours trying to detect the problem, enemies have two states, "ready to move/attack" and "idle", they switch between them every turn.

The function that's giving me trouble is "GetAngleOfSigth", in the event sheet Enemies, under the group ranged, as I said, it works great EXCEPT when the player is straight up at 90°, it try feeding that variable directly to check if it´s that the function isn't working properly, but that´s not the case. It just acts as if it cant the the player.

Any insight is welcomed

Shame on me. I couldn't fully modify your project since I no longer have C3 subscription. However I investigated that the problem lies in event 55 'Pick instance with UID'. When I disabled/remove it, north and south enemy both able to attack. So my conclusion led to how many UID were switching to that specific event execution.

alextro Hi! I´ve been working on other systems, but I just tried delating line 55 in "Enemies" but I still get the same mistake :/ tried in two different PCs in case it was some weird mistake, but it still doesn't work.

thank you nonetheless

I would like to test the LOS behavior on my own by replicate similar battle system of yours to check whether things up to expectation.

alextro I had to stop to keep for work, but I´m about to re-engage this project, I´ll keep you posted if I find a solution!
