C++ Error. A value of "type*" cannot be am entity of type "type*"

Question

As mentioned above, I'm getting this error. I have a class Enemy with the constructor

Enemy(int eHP, string eName, int eExp, int eDamage)

Then I have another class for a linked list with the node adding function

void EnemyList::addEnemy(same as above)
Enemy* newEnemy = new Enemy(same as above without variable declarations)

if (tailE == NULL)
headE = tailE = newEnemy //initialized beforehand
The error is here. It tells me what the question title says. Does anyone know how to fix this?

Answer 1

From what you show it looks ok. So you don't give enough info to identify the problem explicitly.

All I can think of is: Are headE and tailE and newEnemy all of type Enemy*?

I have a sneaking suspicion your error is something like this:
class A {};
class B : public A {};

This will fail to compile (Implicit 'down-casting' is dangerous; you need an explicit cast for it to work)
// A* a = new A;
// B* b = a;

//This will work (Implicit 'upcasting' is safe)
B* b = new B;
A* a = b;

Can you give more info?

Answer 2

Actually you're completely right. The nodes I assigned to the head and tail pointers were of the wrong class. Thanks for helping me out.
