You want to know how to add that kind of function to your own mod?
It's a simple buff that adds a MU entry to the character via BPGetMultiUseEntries.
You will need to enable some booleans in the buff. Don't know the exact names but search for multiuse in the buff, think you'll need to enable 3 or 4 booleans.

@Benzominera Hello, do you mind sharing how do you do "The logs can be opened everywhere by holding "R" and selecting the Open Logs option"? I tried looking into the devkit but didn't find anything

could you make me a mod like this but edited more.
1# what i need is when clearing the logs it works instant for that detector.
2# easy hotkey use when near the detector when using a hot key set, will open up the info to see any activity in logs.
3# when a player brings out a dino it will add up how many dinos that player brings out. if he tosses out 5 dinos it will report and log dino 1, dino 2, dino 3, and so on.
4# a log window that will show all the detector logs combined and the name of the detector's. this log window can remain open and get instant updated live info.
5# a telport button to send the owner to that dino Detector location facing in the set direction selected when placing it down.
6# background color darkness darkend to better see the log info.

You can ask it here too.

can you add me or accept my friend request. i would like to ask if you could build me a mod like this but with some modifications?

That shouldn't happen anymore since yesterdays update. Comment again if it still happens.

Found a bug where the detectors are removed on server restarts.

Yes that's possible, I'll add that in the next update.

Is it possible to filter the wild dino entries by level? It might be a neat way to passively search for high/max level dinos if you set one up in a known spawn area, like setting up a wildlife cam.
