the 100 is a "taxi.x" file..while the 0 is my camera..

+ Code Snippet

float x = dbObjectPositionX (100);
		float y = dbObjectPositionY (100);
		float z = dbObjectPositionZ (100);
		int a  = 0;

		if (((x >= (dbObjectPositionX(0) - 10)) || (x <= (dbObjectPositionX(0) + 10))) || ((y >= (dbObjectPositionY(0))) || (y <= (dbObjectPositionY(0)))) || ((z >= (dbObjectPositionZ(0) - 10)) || (z <= (dbObjectPositionZ(0) - 10))))
		{
			if (a == 0);
			{
			dbText (150, 60, "HAHAHA");
			dbSetTextSize(50);
			}
		}

simple way: make a box, or a plain, position it in the camera, and check for collision between it and the object:

+ Code Snippet

//in the loop
dbPositionObject ( dummyBoxID, dbCameraPositionX(), dbCameraPositionY(), dbCameraPositionZ() );
//-----------
//check
if ( dbObjectCollision ( dummyBoxID, ObjectID ) )
{
//camera is colliding with the 
}
