5E Character Sheet Ammo Decrement

I'm still rather new to learning all of the Roll20 bells and whistles, of which there are many. But my current quest is to find a way that will automatically decrement the character's 'ammo' count for the given ranged weapon that they use. Then, when the ammo counter reaches '0', I as the DM will get a message noting that they are firing a weapon with no ammo. I saw the 'Ammunition Tracker' but it doesn't appear to be built for the D&D 5E character sheet. And if it was, I do not yet have the knowledge and experience to decipher it. Is there something that somebody is already using for this function or can somebody explain in a little more detail how to implement this for the D&D 5E character sheet?

[script] Ammo - Automated ammunition management in a character attribute. Otherwise, you could look into switching over to the D&D 5e Shaped Character Sheet , and installing and using its "auto ammo" script/feature.

Thanks! That's exactly what I was looking for!

It is built into the 5e shaped sheet if you have my script installed and the ammo and auto toggled for new weapons.

Hey. I have been trying to figure out Automated Ammo.  I saw the 'auto' button next to 'ammo' on the shaped 5ed character sheet but it was not changing the ammo value. So I installed and fitted in the script you mentioned above, after searching the forum, and that works, but does not detract from the 'ammo' value on the character sheet, only the value in the ranged_ammo attribute. (Which is puzzling) So I went back to the sheet after reading this thread thinking I was nuts to try the buttons again, and yet nothing. I am using firefox. Al. Oh, my question... .... so whats wrong? I'd like my players to see the ammo value move on their character sheet, and not just in the attributes.

I've just done this for the time being, I mean that would have been way too obvious *facepalm* Still the script is nice and auto arrow usage... *FTW*

It works if you have it toggled in the script and on the sheet.
