Spring.GetUnitWorkerTask(unitID)

Checks a builder's current task

Checks what a builder is currently doing.

Also, it resolves the Repair command into either actual repair, or construction assist (in which case it returns the appropriate "build" command). Only build-related commands are returned (no Move or any custom commands). The possible commands returned are repair, reclaim, resurrect, capture, restore, and build commands (negative buildee unitDefID).

Parameters:
