 The `perk_add_mode`, `set_selectable_perk`, `set_perkbox_title`, `hide_real_perks`, `show_real_perks` and `clear_selectable_perks` control the behaviour of the select a perk box. The `set_selectable_perk` can be used to add additional items by setting the **active** parameter to 1, and to remove them again by setting it to 0. The `set_perkbox_title` can be used to change the title of the box, or by using `""` it will be set back to the default. The `hide_real_perks` and `show_real_perks` can be used to prevent the dialog from displaying any of the original 119 perks. The `perk_add_mode` modifies what happens when a fake perk is selected from the perks dialog. It is treated as a set of flags - if bit 1 is set then it is added to the player's traits, if bit 2 is set it is added to the player's perks, and if bit 3 is set it is removed from the list of selectable perks. The default is 0x2. The `clear_selectable_perks` restores the dialog to its default state.
 
-The `show_iface_tag`, `hide_iface_tag` and `is_iface_tag_active` relate to the boxes that appear above the interface such as **SNEAK** and **LEVEL**. You can use 3 for **LEVEL** and 4 for **ADDICT**, or the range from 5 to (4 + the value of BoxBarCount in **ddraw.ini**) for custom boxes. Remember to add your messages to **intrface.msg** and set up the font colours in **ddraw.ini** if you're going to use custom boxes. Starting from sfall 4.1/3.8.12, `is_iface_tag_active` can also be used to check 0 for **SNEAK**, 1 for **POISONED**, and 2 for **RADIATED**.

 The `get_bodypart_hit_modifier` and `set_bodypart_hit_modifier` alter the hit percentage modifiers for aiming at specific bodyparts. Valid bodypart id's are from 0 to 8. Changes are not saved, and will reset to the defaults (or to the values specified in **ddraw.ini** if they exist) at each reload.
