"new" always returns the same pointer

[YarrOfDoom]

I have written a class which allocates an array of unsigned chars using new, but when I create multiple instances of this class, they all point to the same block of memory. Any idea what I'm doing wrong here?

//the relevant code in the constructor
//v is an unsigned char*
//r and c are integers
//init is an unsigned char
this->v = new unsigned char[r*c];
memset(v,init,r*c);
 

//the code which creates the objects
//water,hills and active are all an uninitialised FieldMap
//gs.rows and gs.cols are integers
this->water = FieldMap(gs.rows,gs.cols,255);
this->hills = FieldMap(gs.rows,gs.cols,128);
this->active = FieldMap(gs.rows,gs.cols,128);

Fixed it. Stuff like this is what you get when you mix some Java in your C++.

The change, for those interested:

//the code which creates the objects
//water,hills and active are all an uninitialised FieldMap*
//gs.rows and gs.cols are integers
this->water = new FieldMap(gs.rows,gs.cols,255);
this->hills = new FieldMap(gs.rows,gs.cols,128);
this->active = new FieldMap(gs.rows,gs.cols,128);

Just something I would note:
why aren't you typing the first new -
//the relevant code in the constructor
//v is an unsigned char*
//r and c are integers
//init is an unsigned char
this->v = new unsigned char[r*c];
memset(v,init,r*c);



instead:
typedef unsigned char* myOddType;

main()
.
.
.
this->v = (myOddType) new myOddType[r*c];
memset(v,init,r*c);
