Zerg specific acts

Zerg specific tactics

Use ZergUnit to produce all new units and it will also morph units automatically if the desired unit is a unit that should be morphed. It is recommended to use ZergUnit for all units for zerg, but MorphRavager morphs Roaches to Ravagers and other morph classes are also available.

SpreadCreep for a simple creep spread, requires enough queens for them to have energy

InjectLarva For injecting larva. Requires free Queens.

Vs Terran flying buildings

Use CounterTerranTie as buildorder wrapper to prevent Terran bots from flying away with their buildings and stalling the game.

final_build_order = CounterTerranTie([build_order])
plan = BuildOrder(
    CounterTerranTie([build_order])
    tactics
)

Extractor Trick (at 14 supply)

extractor_trick = SequentialList(
    Step(
        Supply(14),
        BuildGas(1),
        skip=UnitExists(
            UnitTypeId.EXTRACTOR, include_killed=True, include_pending=True
        ),
    ),
    Step(
        UnitExists(
            UnitTypeId.EXTRACTOR,
            1,
            include_pending=True,
            include_not_ready=True,
        ),
        ZergUnit(UnitTypeId.DRONE, to_count=14),
    ),
    # SequentialList will take care of making sure the drone was made
    Step(
        UnitExists(UnitTypeId.EXTRACTOR),
        CancelBuilding(UnitTypeId.EXTRACTOR, to_count=0),
        skip=UnitExists(
