[RTS Engine] CustomEvents

GameManager에 들어있음

여기서 이런저런 이벤트들의 Callback들이 여기로 다 모임

 

CustomEvents.cs

public delegate void UnitEventHandler(Unit Unit);
public static event UnitEventHandler UnitCreated = delegate {};
public static event UnitEventHandler UnitDead = delegate {};
public static event UnitEventHandler UnitSelected = delegate {};
public static event UnitEventHandler UnitDeselected = delegate {};
public static event UnitEventHandler UnitStartMoving = delegate {};
public static event UnitEventHandler UnitStopMoving = delegate { };
public static event UnitEventHandler UnitWanderToggled = delegate { };
public static event UnitEventHandler UnitInstanceUpgraded = delegate { };

public static void OnUnitDead (Unit unit) //called when a unit is dead
{
	UnitDead (unit);
}

 

 

Custom Events

 

DemoSceneManager

public class UnitCustomEvents : MonoBehaviour
    {
        //This component uses the custom delegate events to monitor unit related custom events and modify the unit's behavior in the demo scene

        //listen to custom events
        private void OnEnable()
        {
            CustomEvents.UnitDead += OnUnitDead;
        }

        private void OnDisable()
        {
            CustomEvents.UnitDead -= OnUnitDead;
        }

        //called each time a unit is dead
        private void OnUnitDead (Unit unit)
        {
            if(unit.gameObject.GetComponent<UnitRagdollEffect>())
                unit.gameObject.GetComponent<UnitRagdollEffect>().Trigger(); //trigger the ragdoll effect

            unit.GetSelection().ToggleSelection(false, false); //disable the unit's selection since it's dead.
        }
    }

 

 

① 여러 Callback들이 CustomEvent로 온다.

② CustomEvent에서 Callback를 받으면, 해당 콜백에 맞는 event를 호출한다

③ 거기에다가 등록을 시켜놓으면 Callback이 왔을 때 해당 이벤트가 실행되게 된다.

 

위 코드의 경우, 유닛이 죽었을 때 OnUnitDead(Unit unit) 매소드가 실행되도록 구현
