Ok some context. I would like to run the game Silent Death (a miniature game) on Roll20. Each ship in the game has a damage track (example below). Is there a way to trigger something within the sheet as damage is applied to the ship? Reduce the Drive setting, reduce damage reduction, etc.
only if the sheet code is updated with Action Buttons, https://wiki.roll20.net/Button#Action_Button
Or you use API like ChatSetAttr to make the changes. both solutions require pro subscription to implement.
Sheetworkers (https://wiki.roll20.net/Building_Character_Sheets#Sheet_Workers_Scripts) might also be able help, too. You can have a sheetworker trigger when a value on the sheet is changed, and it can change other values on the sheet.
