How come I can not use class initialization to initalize inherited attributes?

It keeps saying "Class Troll does not have any field named Health"
But, I inherited BaseEnemy within Troll which DOES have a short Health and a short AttackMag.
The class Troll does not have it's own Health but BaseEnemy does and BaseEnemy is the base of Troll.

using namespace std;



Troll::Troll( ):Health( 100 ),AttackMag( 10 )
{
    //ctor
}

void Troll::Attack(Player &Target)
{
    Target.Health -= this->AttackMag;
    if(Target.Health<0)
        Target.Health=0;
}
Void Troll::SpecialAttack(Player &Target)
{
    Target.Health -= (this->AttackMag * 3)
}


Whats going on?

Are you using public inheritance?

*bump*

I still can't figure this out. Can someone help me?
I've tried

Troll::Troll(): BaseEnemy (Health)

but this doesn't work either

Try getting rid of the public in front of baseEnemy. See if that works

Hi Frantz. I haven't tried that yet but I don't think that would be the problem.

But, I found a solution to my problem!

If anyone's interested, here's the renewed source codes! It took me a few hours to solve this
awful problem.

Troll::Troll(short a, short b): BaseEnemy(a,b)
{

    cout<< Health;
}

void Troll::Attack(Player &Target)
{
    Target.Health -= this->AttackMag;
    if(Target.Health<0)
        Target.Health=0;
}
void Troll::SpecialAttack(Player &Target)
{
    Target.Health -= (this->AttackMag * 3);
}

        short Health;
        short AttackMag;

};

#endif // BASEENEMY_H


The reason why it took me so long to solve this was because I never knew about the "calling the base constructor" thing. I researched a lot and finally I stumbled across it after a few hours.

I'm proud to say it works!
