okie, this is one puzzling matter i got.
i am using the framework provided by gameinstitute.com,
and heres what i have at the moment:
//1)I have a derived & concrete class in crystal.h/cpp:
class CrystalApp
//and declared as
CrystalApp theApp;
2)A class hierarchy exists in gameobjects.h file as:
class GameObject
|
class CrystalMaster
|
classes Crystal_A,Crystal_B,PlayArea
GameObject is the abstract base class,
CrystalMaster is the abstract derived class,
Crystal_A,B,and PlayArea are derived concrete classes.
3)in crystal.h, we declare these:
class CrystalApp :...
{...
private:
GameObject* object[8];
GameObject* object1[200];
Crystal_A* crystal_a[4];
Crystal_B* crystal_b[4];
PlayArea* playarea[10][20];
}
4)so in crystal.cpp,
-ALL the arrays of pointers are allocated memory dynamically.
-Each element of the arrays is assign to a GameObject pointer.
example:
for(int i=0; i<4; i++)
{
object[i] = crystal_a[i];
}
-so most operations like Render,Update,Delete are using
GameObject pointers.
5)my current problem:
In order to utilise the pointers stated in CrystalApp class,
i used friend classes.
So most of the code in GameObject.cpp, are quite ugly, like this:
theApp.crystal_a[0]->.........
"theApp" has to be used all the time, coz the pointers belong
to CrystalApp class in private access.
6)I am looking for a more elegant approach, one that does not
compromise the easiness of doing all the memory allocation
in CrystalApp class, and perhaps do not need to use "theApp"
all the time.
Heres what i thought of at the moment,
changing crystal.h stuffz to:
class CrystalApp :...
{...
private:
GameObject* object[2];
GameObject* object1;
CrystalMaster* crystal[2];
CrystalMaster* playarea;
}
and in CrystalMaster class,
class CrystalMaster : class GameObject
{
...
protected:
Crystal_A crystal_a[4];
Crystal_B crystal_b[4];
PlayArea playarea[10][20];
}
How do i actually link, lets say, crystal[0] to the array crystal_a[]??
considering that memory allocation was done like this in crystal.cpp:
crystal[0] = new CrystalMaster(...);
crystal[1] = new CrystalMaster(...);
playarea = new CrystalMaster(...);
Or is there something wrong with this new method?
