How to generic pass class as parameter

Question

public class Skeleton : Monster
{
    private MonsterBaseState state;
    private void Awake()
    {
        state = new PatrolState<Skeleton>(this);
    }
    public void  GetMonsterInfo()
    {
      dosomething;
    }
}
pubilc class ManyMonster:Monster 
{
    private MonsterBaseState state;
    private void Awake()
    {
        state = new PatrolState<Skeleton>(this);
    }
}
//and more monster Class

public interface MonsterBaseState
{
    void BehaviorForUpdate();
}
public class PatrolState<T> : MonsterBaseState
{ 
    private T cluster;
    public PatrolState(T curCluster)
    {
        cluster = curCluster;
        cluster.GetMonsterInfo();//wrong here
    }
        public void BehaviorForUpdate()
    {
    }
}

I can't use the GetMonsterinfo method in the PatrolState Class

I want to pass the skeleton or other monster ， so I don't have to write a lot of status code

`public class PatrolState : MonsterBaseState where T:Skeleton ` — Chetan, Dec 03 '21 at 03:43

Rather have a common base **class** which already implents the core members and behavior instead of inheriting from `MonoBehaviour` everytime — derHugo, Dec 03 '21 at 07:29

You can implement interface IMonster as below:

public interface IMonster
{
    void GetMonsterInfo();
    //void MonsterMethod1();
    //void MonsterMethod2();
    //..
}

public class Skeleton : MonoBehaviour, IMonster
{
    private MonsterBaseState state;
    private void Awake()
    {
        state = new PatrolState<Skeleton>(this);
    }
    public void GetMonsterInfo()
    {
    }
}

public interface MonsterBaseState
{
    void BehaviorForUpdate();
}

public class PatrolState<T> : MonsterBaseState where T :IMonster
{ 
    private T cluster;
    public PatrolState(T curCluster)
    {
        cluster = curCluster;
        cluster.GetMonsterInfo();//wrong here
    }
    
    public void BehaviorForUpdate()
    {
    }
}

I use lots of skeleton.method() in PatrolState Class,It means implement many interfaces？ – KDYG Dec 03 '21 at 03:52
@KDYG Just need only one interface IMonster, and extend it. – Infosunny Dec 03 '21 at 03:58
@derHugo I'm sorry, I didn't notice that where using new on MonoBehaviour. – Infosunny Dec 03 '21 at 07:43
