Ammo provides inventory management for ammunition stored in a character attribute. 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.

Note: As the GM, bounds will not be enforced for you. You will be whispered the warnings, but the operation will succeed. You will also be told the previous and current state in case you want to revert the change.

Script is sheet-agnostic, and can be made to work with any system.

Commands

!ammo <id> <attribute> <amount> [resource name]

This command requires 3 parameters to process correctly, as shown above.

Parameters	Description
id	token_id} if your token is set to represent a character. See Link Token & Sheet
attribute	The name of the attribute representing ammunition. Note: this is the name without @{ } around it. This works with repeating sections as well, but you will need to find the repeating rowid to build the attribute name, or use the row index
amount	The change to apply to the current quantity of ammo. Use negative numbers to decrease the amount, and positive numbers to increase it. You can use inline rolls to determine the number.
resource name	Anything you put after the amount to adjust by will be used as the resource name (default: "ammo").

!wammo <id> <attribute> <amount> [resource name]

This command is identical to !ammo, but will whisper all output.

Examples

Shoot 1 arrow:

!ammo @{character_id} arrows -1 arrow

Shoot 3 arrows:

!ammo @{character_id} arrows -3 arrow

Recover 1d6 arrows:

!ammo @{character_id} arrows [[1d6]] arrow

Refill all arrows (by picking up the difference between the current and max value).

!ammo @{character_id} arrows [[@{selected|arrows|max}-@{selected|arrows}]]

Using a repeating group's field with rowid:

!ammo @{character_id} repeating_weapons_-J1as31234_weapon_arrows -1 arrows

Using a repeating group's field with index:

!ammo @{character_id} repeating_weapons_$2_weapon_arrows -1 arrows

Whisper ammo changes to yourself:

!wammo @{character_id} arrows -1 arrow

Examples - Sheet-specific

D&D 5E by Roll20 recover 1d4 crossbow bolts (second row of items in the inventory)

!ammo @{selected|token_id} repeating_inventory_$1_itemcount [[1d4]] bolts
