Sheetworkers are just javascript, except without any access to the DOM. The only way for your sheetworker script to interact with the VTT is through the functions detailed in the wiki (all of which,except for generateRowID, are asynchronous). I'd recommend looking up some javascript tutorials online and pulling the code for some sheetworker driven character sheets from the github repository. You may have to contact sheet authors to get non-minified code. There are a few additions to the "just javascript" though: The sheetworkers also have access to the underscore.js library The Promise and async/await syntax from ES6 and ES7 respectively does not work with sheetworkers as it breaks the relationship between the running code and the specific character sheet it should be interacting with. A suggestion: I would recommend keeping your number of getAttrs and setAttrs to a minimum for any given operation. Making long chains of these can cause performance issues with the sheet. I am pretty new to the whole sheet creation scene, so I'm sure others will have better/different advice. Scott EDIT: Also, the sheetworkers, like API scripts, are event driven. This may be part of the cause of the disconnect you are experiencing.
