i havent realy the time to explane how it needs to be done

you need to create a panel with digits

Code:
PANEL* plate_text =
{
	digits(0,0,"your standaard text %s",*,1,you_string);
	flags = SHOW | OVERLAY;
}


then you while need to atach it to your entity

Code:
action plate()
{
	plate_text.size_x = 256;//size of the bitmap of your entity
	plate_text.size_y = 64;//size of the bitmap of your entity
	plate_text.target_map = bmap_for_entity(my,0);
}


NOTE !!!! reset the target_map to null when new lvl needs to be loaded

"empty"
