All worker assignment is handled by the WorkerManager class, which is a globally accessible singleton class. It can be accessed by calling Global::Workers()

Workers in UAlbertaBot can have one of the following WorkerJob assignments:

• Minerals - Mine minerals from a given mineral patch
• Gas - Gather gas from a given refinery
• Build - Build a building
• Combat - Help defend main base location
• Idle - No current assignment
• Repair - Repair a building
• Move - Move to a building's construction location
• Scout - Scouting the map
• Default - Default constructor value

All WorkerJobs are listed in an enum, and once assigned are stored in a std::map inside WorkerData. You can get the status of a worker by calling WorkerData's getWorkerJob() or setWorkerJob() methods.

On each frame, WorkerManager.update() performs the following logic:

• WorkerManager.update()
  • Re-allocate workers to new mineral patches if mined out
  • Send idle workers to gather minerals
  • Allocate gas workers until 3 in each refinery
  • Move build workers to building location if necessary

When a worker is trained, its status is initially set to Default. When the update() function is called and detects that the unit it Idle, it sets the unit to gather minerals at the closest known resource depot, up to a cap of 3 workers per mineral patch per resource depot. Similarly, when a refinery is constructed, it sends 3 mineral workers to gather gas from that refinery.

The only additional behaviour for workers is that they are able to be set to scout or combat. This is done inside GameCommander and CombatCommander respectively. These classes remove the current worker job from WorkerManager and control them via ScoutManager or Squad respectively.

If you wish to modify the behaviour of worker allocation, these are the locations of the code which you need to change.
