OT: Stupid c++ (Roguelike development)

[PvK]

Sounds like your mouse button is getting stuck in a down position, or software (mouse driver, or some program messing with mouse messages in a bad way) is messing up the mouse. Like, saying it has handled the MouseUp message and not passing it on to other software, so other programs don't see the MouseUp event so it's like your mouse button is stuck down.

I think it's my keyboard - Tapping the shift key has helped twice now, so it's probably dying.

The mouse is only about 6+ months old; can't remember when we got the keyboard, but it's outlasted at least two processors, I think.

What does 'expected primary-expression before '.' token' mean? I'm trying to make a pointer for a base class equal to one of its derived classes.

Thanks again.

Ah, the joys of dereferencing.

. is used to access members of an object.

-> is used to access members of an object when you have a pointer to that object.

If you have:

object* MyObjectPtr = new object();

then you have to access members via:

MyObjectPtr->member();

Whereas if you have just:

object MyObject;

you use:

MyObject.member();

Erm, the pointer is one of the variables in the base class. I'm restarting the roguelike project, only mucho simpler.
The relavent lines:

class GR {
BlankSquare MapBlank; WallSquare MapWall; FloorSquare MapFloor;
};

class MapSquare {
public:
BlankSquare * Type;
};
MapSquare Map [81][41];

Map [t][t2].Type = GR.MapWall;

*Whaps forehead*

Must remember...A class is *Not* a variable. Must declare class as variable first.

Well, at least I changed the error...Er, never mind. Putting '&' in front of what I wanted to convert fixed it. And now it all works. Or seems to. Can never tell with those programs. *Darting eyes* Sneaky programs.

I'm getting aa '[Linker error] undefined reference to `vtable for Character' '
Ok, so it doesn't like virtual functions without a '{};', even if they are void.
