Is this in the program now? I cannot seem to get it to work..
Using 1.13-version v0-3967-g27954b (gitHub release) from 23.05.2023 for this video
Currently it only works with LRAK SAW-Vest and some belts/weapons added after the feature got implemented (2012, so a few ...) ain't yet defined to use it
So, only this vest will work. And not all ammo belts. the ones that do show the symbol you can see at video in item description. and if conditions are met, the merc faces will show the symbol too.
I'm currently tinkering on it to update it. But apart from some not yet defined items (and the symbol indicating feedable for weapons) it's working fine. 4x 200 in vest-slots and if weapon also fits 200, that's a whopping 1000 bullets
it will drain your merc, see the "?" in the video instead of cursor at some point. That's when Ace run out of enough BP.
you can check items.xml for the flags in first post to see which items are used at the moment
edit: video is partly mute due to copyright complaint about the music. taught me something, next ones will be mute or using SSA
