I guess you could create a table with the information in and loop through
checking for matches. Have three columns with object1 and object2 in plus a
callback function that would be called when the two objects collide.  I
can't remember the exact syntax sorry. I know it looks a bit long winded but
adding a new 'interaction' would then be just a case of adding another entry
into pData:



enum
{
    OBJECT_PLUG = 0,
    OBJECT_SOCKET,
    OBJECT_KEY,
    OBJECT_LOCK,
    OBJECT_BUCKET,
    OBJECT_FOUNTAIN,
    ...
    MAX_OBJECTS

} OBJECT;


typedef void CallBackFunc (void);

void PlugIntoSocket (void);
void KeyIntoLock (void);
void FillBucket (void);


struct
{
    OBJECT obj1;
    OBJECT obj2;
    CallBackFunc pFunc;

} INTERACT_DATA;


INTERACT_DATA pData[] = {
    {OBJECT_PLUG,    OBJECT_SOCKET,   PlugIntoSocket },
    {OBJECT_KEY,     OBJECT_LOCK,     KeyIntoLock    },
    {OBJECT_BUCKET,  OBJECT_FOUNTAIN, FillBucket     }    };
