Hi
I am a noob and learning C++ and DGDK. I am trying to figure out how to use pointers and dynamic memory things.
I was wondering if this is possible, or how I should go about it:

Say I have a class for making a monster (in this case a sphere for example sake) in a game:



now to make a monster I can say : CMonster monster(100,100);

and to run its moving code : monster.run();

I know I can have an array without the constructer:
CMonster monster[50];
monster.setup(100,100);

and then use: monster[1].run()

Here is my question: If I use the array, I am limited to how many "monsters" I can make in my program. What I want to know is: is it possible to use dynamic memory stuff to make new "monsters" and run them whenever I need to (e.g. a RTS game)? something like:

new CMonster (100,100);

and then also to use the monster.run() command.

Is this possible or am I missing the plot and being silly? And how would you point to the new "monsters"? Is there a simpler way I am not seeing?

Thanks

I don't think you can supply parameters if it's declared with new.

But, that aside, you can't declare a name for it. You have to assign the new command to a pointer. For example,



Then, since it's a pointer, you can only access it's member functions like so:

Yeah...thanks that makes sense.. very helpful
cus then I can just say:

monster->run();

Thanks alot, Ill play around with that.

I saw this example:


I was looking at that


and that made me wonder if you could constantly change, having different numbers of "monsters" using the run code:

monster[ x ] -> run ( );

where x could change (if that makes sense). Thanks for your help

That will work, but you must be careful. Depending on the memory requirements of the class, it can add up fast.

Take a look at the C++ vector class - it provides pretty much the same functionality as an array, and variable sizing too.
