Passing arguments to base constructor fails

Questions & Answers

I have a Character class with a ragdoll and a HumanoidCharacter subclass that should set it.

public class Character : MonoBehaviour {
    private Ragdoll ragdoll;
    
    public Character(Ragdoll ragdoll, int maxInventorySize) {
        if (ragdoll == null) throw new System.ArgumentNullException("ragdoll");
        this.ragdoll = ragdoll;
    }
}

public class HumanoidCharacter : Character {
    public HumanoidCharacter(int maxInventorySize) : base(new Ragdoll(new ItemSlot[] {new ItemSlot(ItemSlotType.RightHand)}), maxInventorySize) {
}
}

public class PlayerCharacter : HumanoidCharacter {
    public PlayerCharacter() : base(32) {
    }
}

I’m getting the ArgumentNullException for ragdoll when I attach PlayerCharacter to a GameObject.

I would have thought that PlayerCharacter’s constructor is called, which calls HumanoidCharacter’s sonstructor which then calls Character’s constructor with the new Ragdoll. What’s going wrong?

I have in the mean time read, that using Constructors for MonoBehavior is generally discouraged. I changed my code to set those variables in Awake instead. Now it works.
