Function PlaceGroup

editor/Group.cpp:401–429

Place the given group at the specified room face The function merely causes the group to be drawn in the editor, allowing the user to line it up before attaching it. The function AttachGroup() must be called to do the actual attachment. Parameters: destroomp, destside - where to place the group g - the group to place

// Parameters:	destroomp, destside - where to place the group
//					g - the group to place
void PlaceGroup(room *destroomp, int destface, group *g) {
  // Clear the placed room, if one exists
  Placed_room = -1;

  ASSERT(destroomp->faces[destface].portal_num == -1);

  // Set globals
  Placed_group = g;
  Placed_room_orient.fvec = destroomp->faces[destface].normal;
  Placed_room_angle = 0;
  Placed_baseroomp = destroomp;
  Placed_baseface = destface;
