How do I mark an airdrop?

Look directly at the airdrop in the sky as it's falling and hit CTRL+E on your keyboard.

How do I view the flight path?

Toggle open the MapMate overlay by hitting CTRL+Q on your keyboard and you'll see the flight path on top of the map (it doesn't show up until you've been in the plane for a few seconds though).

How do I view my marked drops?

Toggle open the MapMate overlay by hitting CTRL+Q on your keyboard. If you see the little loading spinner in the bottom-right-hand corner of the map, it means that some of your marked drops are still processing.

Why am I only allowed to have 3 drops processing at a time?

The code for processing airdrops is quite intensive and we don't want your computer to blow up if you don't read these instructions and go off and mark a bazillion air drops at once because you think it's not working.

Why can't I mark drops more quickly?

See above :) Also, we reckon it'll take a little bit time for you to move the 50-100 meters that are recommended for proper triangulation, so we can't think of a good reason to let you mark air drops more often than the 3 second interval.

Why do my drops sometimes process and then not show up?

TLDR: Because the background behind your compass when you hit the hotkey was too messy.

Long Answer: The PUBG API does not allow developers to get information about which direction the player is facing, so the backbone of the airdrop marking aspect of MapMate is done via OCR (Optical Character Recognition) on the compass image. If you haven't heard of this before, it basically means there's some fancy code that looks at the compass image at the top of your screen and tries to understand what the text in it says. (N, S, E, W, etc.) It's quite intense to run this code accurately, which is why those little CAPTCHAs that you have to fill out when
submitting forms online work to stop spam bots.

So with that said, if you have a bunch of tree branches (or whatever) right behind the compass text when you hit CTRL+E, our code might have a difficult time understanding what the text says, since those branches show a little bit through the background behind the compass.
