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

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?

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?

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.
