Adding an ObjectType

I want to make new mTypeMask, but when I go to ObjectTypes.h, this message is shown at the top:

//-------------------------------------------------
// Types used for SimObject type masks (SimObject::mTypeMask)
//

/* NB! If a new object type is added, don't forget to add it to the
* consoleInit function in simBase.cc
*/

enum SimObjectTypes
{
#define bit(x) (1 << (x))

// Types used by the SceneObject class
DefaultObjectType = 0,
StaticObjectType = bit(0),
//... ect
//-------------------------------------------------

Okay, so I go to the consoleInit function in simBase.cc and it looks like this:

//-------------------------------------------------
void SimObject::consoleInit()
{
}
//-------------------------------------------------

What do I add? "enum SimObjectTypes MyObjectType = bit(25)";?
