I have been writing a game and some of my objects have objecs as
members of that I have a graphic with a color or unit with a coord
structure.
If I have a:
class unit{
color cl;
int attackFactor;
.....
.....
When I create the object, I create an empty color but I have a color
constructor:
color::color(int r, int g, int b);
I want to create the unit
unit::unit(int af, int r, int g, int b);
attackFactor =af;
color(r,g,b);
My unit objects will have quite a bit of data so I want to load all the
information with istream from a text file. How can I use constructor
for the member objects of my unit object or any other object that is a
member of another object. 6 1360

Use an initialization list: http://www.parashift.com/c++-faq-lit....html#faq-10.6

Read about "initialiser list" in your favourite C++ book.

That is unit::unit(int x, int y) : xloc(x), yloc(y)?
So I can:
unit::unit(int x, int y, int z) : xloc(x), yloc(y), color cl(z);
Have to look up the correct syntax.
for example?
I thought I would have to:
class unit{
color * cl;
int attackFactor;
....
unit::unit(int af, int r, int g, int b);
attackFactor =af;
cl = new color(r,g,b);
and use a bunch of pointers.
I will have the C++ programming language I hope I can find somthing
useful there.

Did you mean to use '{' instead of ';'?
attackFactor =af;
cl = new color(r,g,b);
and use a bunch of pointers.
I don't see what "a bunch of pointers" have to do with it, but I am
not as bright as I used to be...
Again, instead of using assignments, use initialisation list. Read
the FAQ, it's all explained there.

If you mean the Bjarne Stroustrup's book, you definitely can.

Nope. See the FAQ.

I presume you mean the book by Stroustrup. Hopefully your next
investment will be in a proofreader. It's hard to follow what you're
typing.

If your colour is fixed you could also use a template:
template<int R, int G, int B>
struct color{
static const int red = R;
static const int green = G;
ststaic const int Blue = B;
};
typedef color<255,0,0red;
etc.
