I know you weren''t asking me, but that''s what I would do. I''d make the function virtual so that ''special'' Entity types could override the attack method.
what do you mean by... well all of that?
should i consolidate my classes??

if i were to do that i would have to implement some sort of damage mod variable... maybe pass it by refernce or maybe ill just make it a member variable of the entity class
also... if i wanted to do a damage mod thing.... i would have to use a double to calculate the damage mod like damage*1.06 for 6% damage increase........... but a player health has to be a whole number (integer) so how do i have the final damage be an int but its calculated with a double? would i get warnings or errors or what? not only that, but wouldnt it round the .06 to 0 and give me no damage mod. just wonderin how i could do this. thanks

You shouldn''t have to cast an int to float, it might be cast automatically. But I wouldn''t count on that behavior. You would have to cast the damage variable to float explicitly to avoid warnings/errors. When the result is assigned back to damage, it''ll be re-cast to int (or whatever type damage is) and the decimal portion will drop (0.06 will be 0, 1.06 will be 1, etc.).
So damage = (float)damage*1.06f would do what you ask.

It seemed that you were specifically speaking to Creative, though I could be mistaken.

Virtual functions allow you to define a default behavior for a base class and all of its derived classes. In this case, the Entity class. Derived classes, though (say, a specific type of enemy, maybe a boss?), can override that function.
At runtime, the specific type of object that is being operated on will be determined. If that object has overridden the function, the class specific function will be executed. Otherwise, the default one in the base class will be run.
Note that there is some debate over whether virtual functions incur too much cost to be efficient. According to Scott Meyers, who has written various books on C++, (and this logic makes sense to me), resolving a virtual function takes about 3 more instructions than it takes to follow a regular function pointer. I know I couldn't do these things without virtual functions and have it cost less than 3 instructions.

int moddeddamage = damage * 106 / 100; No casting, or use of FP at all this way. Be sure to do the multiplication first or you''ll get horrible precision.
