Build Marine! and Attack!

이 장에서 배울것

자원이 되면, supply depot을 짓고, Barrack을 지은 뒤, 공격가는 것을 목표로 하겠습니다.

Let's Start!

사실, 서플라이 디팟 하나 짓게하는데도 은근히 생각해볼 것들이 많습니다.

서플라이디팟을 짓는다.
- 인구수 체크!
- 지금 서플라이디팟을 짓고있는지 확인!
- SCV가 노는지 체크!
- 자원 확인!(지금 가능한행동인지확인!)
- SCV를 선택해 적당한 위치에 짓기 시작해야합니다.

이렇게 rule-based가 어렵습니다 ㅜㅜ. 한꺼번에 적용한 스크립트를 보고 빠르게 넘어가도록하죠!

class Agent(base_agent.BaseAgent):

        elif (len(obs.observation.multi_select) > 0 and obs.observation.multi_select[0].unit_type == unit_type):
            return True

        if len(units) > 0 :
            return True
        else:
            return False
        
    def step(self,obs):
        super(Agent,self).step(obs)
        if obs.first(): 
            player_y, player_x = (obs.observation.feature_minimap.player_relative == PLAYER_SELF).nonzero()
            xmean = player_x.mean()
            ymean = player_y.mean()
            if xmean <= MINIMAP_SIZE/2 and ymean <= MINIMAP_SIZE/2:
                self.scout_coordinates = (40, 40)
            else:
                self.scout_coordinates = (20, 20)
        scvs = [unit for unit in obs.observation.feature_units if unit.unit_type == units.Terran.SCV]
        if len(scvs) > 0 and not self.unit_type_is_selected(obs,units.Terran.SCV):
            #유닛 셀렉
            scv = scvs[0]
            return actions.FUNCTIONS.select_point("select",(scv.x,scv.y))
        elif self.can_do(obs,BUILD_SUPPLYDEPOT) and \
        self.food_check(obs) and \
        (not self.build_building_now(obs,units.Terran.SupplyDepot))\
        and  [x.order_id_0 for x in obs.observation.feature_units if x.is_selected == 1][0] == \
        HARVEST_GATHER_SCV_UNIT: 
            x,y = random.randint(0,SCREEN_SIZE),random.randint(0,SCREEN_SIZE)
            return actions.FunctionCall(BUILD_SUPPLYDEPOT,[NOT_QUEUED,[x,y]])
        elif self.can_do(obs,BUILD_BARRACKS) and \
            (not self.build_building_now(obs,units.Terran.Barracks)) and \
            (len([x for x in obs.observation.feature_units if x.unit_type == units.Terran.Barracks]) == 0) and \

            return actions.FunctionCall(BUILD_BARRACKS,[NOT_QUEUED,[x,y]])
        return actions.FUNCTIONS.no_op()

만약 서플라이디팟을 짓다가 화면밖으로 벗어나면 이러한 rule-based Agent는 짓고있는 서플라이 디팟에 대한 정보는 얻을 수가 없어 인구수가 막히지 않았더라도 새 서플라이디팟을 지을 가능성이 있습니다!(자원이 많다면 APM이 300이니까 잠시 다른화면으로 한눈을팔았다간 몇초만에 모든 일꾼이 서플라이 디팟을 짓는 것을 볼 수 있습니다.)

이번엔 배럭을 지어보겠습니다!

if (len([x for x in obs.observation.feature_units if x.unit_type == units.Terran.Barracks]) == 1)\
and self.can_do(obs,TRAIN_MARINE_QUICK):
    return actions.FunctionCall(TRAIN_MARINE_QUICK,[NOT_QUEUED])

이 스크립트도 스크린에 배럭이 보이지않으면 와장창 지어지는 문제가 있습니다..ㅎㅎ

이제 마린을 계속해서 뽑아보겠습니다.

    def step(self,obs):
        super(Agent,self).step(obs)
        if obs.first(): 
            player_y, player_x = (obs.observation.feature_minimap.player_relative == PLAYER_SELF).nonzero()
            xmean = player_x.mean()
            ymean = player_y.mean()
            if xmean <= MINIMAP_SIZE/2 and ymean <= MINIMAP_SIZE/2:
                self.scout_coordinates = (40, 40)
            else:

        scvs = [unit for unit in obs.observation.feature_units if unit.unit_type == units.Terran.SCV]
        brracks = [unit for unit in obs.observation.feature_units if unit.unit_type == units.Terran.Barracks]
        if len(scvs) > 0 and len(brracks) == 0 and not self.unit_type_is_selected(obs,units.Terran.SCV):
            #유닛 셀렉
            scv = scvs[0]
            return actions.FUNCTIONS.select_point("select",(scv.x,scv.y))
        elif self.can_do(obs,BUILD_SUPPLYDEPOT) and \

            return actions.FunctionCall(BUILD_SUPPLYDEPOT,[NOT_QUEUED,[x,y]])

        elif len(brracks) == 1 and not self.unit_type_is_selected(obs,units.Terran.Barracks): 
            brrack = brracks[0]
            return actions.FUNCTIONS.select_point("select",(brrack.x,brrack.y))

            return actions.FunctionCall(TRAIN_MARINE_QUICK,[NOT_QUEUED])
        return actions.FUNCTIONS.no_op()

처음에 SCV를선택할때, 배럭도 지켜봐야하기때문에 전체의 코드를 넣어 바뀐점을 찾도록 하였습니다. 그러면 이렇게되면 계속 마린을 뽑을 수 있게 되었습니다. 마지막으로 적의 기지로 공격을 보내겠습니다.
