Ammo - repeating resource drops below 0

I am using Ammo with the 5e OGL sheet. I am tracking Rations and Waterskin as resources. I am identifying the repeating resources with the row id, as in... !ammo @{Snowy|character_id} repeating_resource_-MOlHjBE4tSielh3s701_resource_left -1 days water ... and that is working fine. However, when I run that, and the value is zero, it warns me, but increments it to -1 anyway. The script description says... If the adjustment would change the attribute to be below 0 or above it's maximum value, a warning will be issued and the attribute will not be changed. ... How can I get it to remain 0, and not drop below that?

For players, it won't go below zero.  It lets the GM do whatever they want.

I see. I was hoping, as the GM, to be able to hit a macro button, lower all the player's rations & water by one. Any way to turn that functionality off in this case?

Not built in, I need to update that script. If you import the script from the 1-click, then go down to line 85 and find this: if( playerIsGM(playerid) || valid ) { and change it to this: if( valid ) { It will treat the GM like any other person.

Oh cool! Thanks so much - you rock.

One more question about Ammo... is there a way to do a refill? Like, instead of incrementing by a positive or negative amount, can we set a value? Or read the total/max amount and set the value to that?

Not built in, but if there is a maximum set, you can just adjust up by some very large number and it will set it to the max for the attribute.

Ammo is great! But I use the ChatSetAttr script to refill certain things I track with Ammo. It has a built-in --reset option to set things to their max value. Here is an example with a custom attribute ("helmcharges") added to the character to track the charges. !setattr --reset --fb-public --fb-header Recharging *Helm of Healing* --sel --helmcharges

@Rabulias - see this thread ( <a href="https://app.roll20.net/forum/post/9607071/use-chatsetattr-to-adjust-repeating-resource" rel="nofollow">https://app.roll20.net/forum/post/9607071/use-chatsetattr-to-adjust-repeating-resource</a> &nbsp;) where I'm pursuing this solution for ChatSetAttr , some success but an interesting remaining issue.
