- name: Stats
doc: The `get/set_pc_base/extra_stat` functions are equivalent to calling `get/set_critter_base/extra_stat` with `dude_obj` as the critter pointer. None of these stat functions take perks into account, and neither do they do range clamping to make sure the stats are valid. Use the normal `get_critter_stat` function to get a correctly perk adjusted and range clamped value for a stat.

- name: Alter min/max
doc: The `set_stat_max/min` functions can be used to set the valid ranges on stats. Values returned by `get_current_stat` will be clamped to this range. The `set_pc_` function only affects the player, the `set_npc_` functions only affects other critters, and the `set_` functions affects both.

opcode: 0x8242
doc: Will set the number of additional points a critter has in a skill, on top of whatever they have from their stats and other bonuses. Note that skill points are part of the proto, so calling it on a critter will affect all critters that share the same proto.

doc: Accepts a value of between -100 and 100, and modifies the number of skill points the player recieves when they level up. This is a modification of what would otherwise happen, rather than a replacement. The value is not saved into the save game, so should be reset in the `game_loaded` section of a script.
opcode: 0x8246
- name: Graphics
doc: The graphics functions are only available if the user is using graphics mode 4 or 5. Use `graphics_funcs_available` to check; it returns 1 if you can use them or 0 if you can't. Calling graphics functions when `graphics_funcs_available` returns 0 will do nothing.

opcode: 0x8165
- name: load_shader
detail: int load_shader(string path)
doc: Takes a path relative to the `<GameRoot>\<master_patches>\shaders\` directory as an argument and returns a shader ID. That ID should be passed as the first argument to all other shader functions, and is valid until `free_shader` is called on the ID, the player loads a saved game or the player quits to the main menu.

opcode: 0x81ad
- name: set_shader_mode
detail: void set_shader_mode(int mode)
opcode: 0x81ae
doc: Tells sfall when to use a shader. The parameter is a set of 32 flags which specify the screens on which the shader will be disabled, unless bit 32 is set, in which case the shader will only be active on those screens. Remember that screens are displayed on top of each other; if the player opens the character menu which in combat, the game still considers the player to be in combat. See **sfall.h** for a list of defines.
- name: force_graphics_refresh

doc: Used to add additional traits and perks to the character screen. They will be saved correctly when the player saves and reloads games, but by themselves they will have no further effect on the character. For perks, the allowed range for levels is between 0 and 100; setting the level to 0 removes that perk. For traits, the level must be 0 or 1. The image is a numeric id that corresponds to an entry in `skilldex.lst`. The name is limited to 63 characters and the description to 255 characters by sfall, but internal Fallout limits may be lower.

opcode: 0x81c3
doc: 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.

- name: Virtual file system
doc: The `fs_*` functions are used to manipulate a virtual file system. Files saved here should have paths relative to the data folder, and use backslashes as the directory separator. They will take precedence over files stored in the normal data folder. They will also be saved into save games if you set a flag for them using `fs_resize(fileId, -1)`, so be avoid creating large files. Using `fs_copy` followed by `fs_read_xxx`, you can read the contents of existing files.

- name: Knockback
parent: Combat
doc: The `type` value in the weapon knockback functions can be 0 or 1. If 0, the value becomes an absolute distance that targets will be knocked back. If 1, the value is multiplied by the distance they would normally have been knocked back. Weapon knockback modifiers are applied in the order weapon -> attacker -> target, so a x2 weapon wielded by an abs 6 attacker hitting a /2 target will knock the target back 3 squares. The knockback functions will not override the stonewall perk or knockdowns resulting from criticals. knockback values set on weapons or critters are not saved, and must be reset each time the player reloads.

- name: Maps and encounters
items:
- name: in_world_map
detail: bool in_world_map
opcode: 0x8170
doc: Returns 1 if the player is looking at the world map, or 0 at any other time. Obviously this is only useful in global scripts, since normal scripts will never get the chance to run on the world map.
- name: force_encounter
detail: void force_encounter(int map)
opcode: 0x8171
doc: Can be called either from a global script while traveling on the world map, or from a normal script while on a local map. In either case the encounter occurs shortly after the next time the player moves on the world map. The player will not get an outdoorsman skill check.
- name: force_encounter_with_flags
detail: void force_encounter_with_flags(int map, int flags)
opcode: 0x8229
doc: |
Does the same thing as force_encounter, but allows the specification of some extra options (see **sfall.h** for available flags).
Forcing a random encounter on a map that is not normally used for random encounters may cause the player to lose the car, if they have it. In this case use `force_encounter_with_flags` with the `ENCOUNTER_FLAG_NO_CAR` flag set.
- name: set_map_time_multi
detail: void set_map_time_multi(float multi)
opcode: 0x822a
doc: Adjusts how fast time passes while you're on the world map. It takes a single float as an argument, where 1 is the normal speed. This function works in addition to the `WorldMapTimeMod` setting in `ddraw.ini` and the Pathfinder perk, rather than overriding it, so calling `set_map_time_multi(0.5)` when the player has 2 levels of Pathfinder would result in time passing at 25% the normal speed on the world map.
- name: set_map_enter_position
detail: void set_map_enter_position(int tile, int elevation, int rotation)
doc: Overrides the players entry position when entering the map through exit grids. Setting the tile to 0 will put the player on the start hex (default tile and elevation) of the map. Works only in `map_enter_p_proc` procedure.
- name: get_map_enter_position
detail: array get_map_enter_position()
doc: "Returns an array of the player's position data (index: 0 - tile, 1 - elevation, 2 - rotation) when entering the map through exit grids. If entering from the world map, the tile value will be -1. Should be called in `map_enter_p_proc` procedure to get the correct position data."

detail: int play_sfall_sound(string file, int mode)
opcode: 0x822b
doc: |
Used to play `mp3/wav/wma` files. The path given is relative to the Fallout folder. Specify mode as 1 to loop the file continuously, 2 to replace the current background game music with playing the specified file in loop mode, or 0 to play the file once. If you don't wish to loop, `play_sfall_sound` returns 0. If you do loop, it returns an id which can be passed back to `stop_sfall_sound` when you want to stop the effect. All sounds effects will be stopped on game reload, looping or not. Does not require `AllowDShowSound` to be set to 1 in `ddraw.ini`.
Starting from sfall 4.2.8/3.8.28, you can pass a value in the `mode` argument for a reduced sound volume. To set the volume, You need to convert the number to hexadecimal and use the argument format `0xZZZZ000Y`, where `ZZZZ` is the volume reduction value in range from 0 to 32767 (the value 32767 is mute), and `Y` is the playback mode.

doc: The `list_xxx` functions can be used to loop over all items on a map. `list_begin` takes an argument telling sfall what you want to list (defined in **sfall.h**). It returns a list pointer, which you iterate through with `list_next`. Finally, when you've finished with the list use `list_end` on it. Not calling `list_end` will result in a memory leak. Alternatively, use `list_as_array` to get the whole list at once as a temp array variable, which can be looped over using `len_array` and which you don't need to remember to free afterwards.

doc: Changes argument value. The argument number (`argNum`) is 0-indexed. This is useful if you have several hook scripts attached to one hook point (see `register_hook_proc`).
opcode: 0x823d
- name: register_hook
detail: void register_hook(int hookID)
doc: Used from a normal global script if you want to run it at the same point a full hook script would normally run. In case of this function, `start` procedure will be executed in current global script. You can use all above functions like normal.
opcode: 0x8207
- name: register_hook_proc
detail: void register_hook_proc(int hookID, proc procedure)
doc: |
The same as `register_hook`, except that you specifically define which procedure in the current script should be called as a hook (instead of "start" by default). Pass procedure the same as how you use dialog option functions. This IS the recommended way to use hook scripts, as it gives both modularity (each mod logic in a separate global script with no conflicts) and flexibility. You can place all related hook scripts for a specific mod in one global script!
Use zero (0) as second argument to unregister hook script from current global script.
__NOTE:__ you can hook several scripts to a single hook point, for example if it's different mods from different authors or just some different aspects of one larger mod. When one of the scripts in a chain returns value with `set_sfall_return`, the next script may override this value if calls `set_sfall_return` again.
__Example:__ Sometimes you need to multiply certain value in a chain of hook scripts. Let's say we have a **Mod A** which reduces all "to hit" chances by 50%. The code might look like this:
```js
original_chance = get_sfall_arg;
set_sfall_return(original_chance / 2);
```
**Mod B** also want to affect hit chances globally, by increasing them by 50%. Now in order for both mods to work well together, we need to add this line to **Mod A** hook script:
```js
set_sfall_arg(0, (original_chance / 2));
```
This basically changes hook argument for the next script. **Mod B** code:
```js
original_chance = get_sfall_arg;
set_sfall_return(original_chance * 1.5);
set_sfall_arg(0, (original_chance * 1.5));
```
So if you combine both mods together, they will run in chain and the end result will be a 75% from original hit chance (hook register order doesn't matter in this case, if you use `set_sfall_arg` in both hooks).
The defines to use for the `hookID` are in **sfall.h**.
opcode: 0x8262
- name: register_hook_proc_spec
detail: void register_hook_proc_spec(int hookID, procedure proc)
doc: Works the same as `register_hook_proc`, except that it registers the current script at the end of the hook script execution chain (i.e. the script will be executed after all previously registered scripts for the same hook, including the `hs_<name>.int` script). In addition, all scripts hooked to a single hook point with this function are executed in the exact order of how they were registered. In the case of using `register_hook` and `register_hook_proc` functions, scripts are executed in reverse order of how they were registered.
**The execution chain of script procedures for a hook is as follows:**
1. Procedures registered with `register_hook` and `register_hook_proc` functions (executed in reverse order of registration).
2. The `hs_<name>.int` script.
3. Procedures registered with the `register_hook_proc_spec` function (executed in the exact order of registration).

- `self_obj` will be reverted to its original value after the next function call.
- Calling `set_self(0)` will also revert `self_obj` to its original value. It is recommended to call this after each use of `set_self` in normal scripts in order to avoid unforeseen side effects.
- `source_obj`, `target_obj`, and similar functions will not work if preceded by `set_self`.

doc: Returns the data at the specified offset of an object (see `OBJ_DATA_*` constants in **define_extra.h** for offsets).
macro: sfall.h
- name: set_object_data
detail: set_object_data(ObjectPtr object, int offset, int data)
doc: Sets the data at the specified offset of an object.

- name: get_flags
detail: int get_flags(ObjectPtr obj)
doc: Gets the current value of object flags (see **define_extra.h** for available flags).
macro: sfall.h
- name: set_flags
detail: void set_flags(ObjectPtr obj, int flags)
doc: Sets the current flags of an object. All flags are rewritten with given integer, so first get current flags with `get_flags` and use `bwor/bwand` to set/remove specific flag.
macro: sfall.h
- name: set_unique_id
detail: int set_unique_id(ObjectPtr object, int flag)
doc: |
Assigns a unique ID number to the object and returns it. If a unique ID number has already been assigned to an object, then ID number is returned without reassignment. `flag` is optional.
- items with unique IDs will not stack with other items of the same type in the inventory
- to just get the current ID number of an object, use `get_object_data(object, OBJ_DATA_ID)`
- unique ID numbers are saved in your savegame, and have a range from 0x10000000 to 0x7FFFFFFF
- there is also a unique ID number range for the player and party members from 18000 to 83535
- to assign a new ID number generated by the engine to the object (i.e. unassign a unique ID), call the function with two arguments and pass -1 for the flag argument
macro: sfall.h
- name: set_scr_name
detail: void set_scr_name(string name)
doc: |
Overrides the name of the script object that was set from `scrname.msg`.
- The changed name will be reset each time the player leaves the map or reloads the game
- Passing an empty string ("") to the `name` argument or omitting it will allow the game to get the name for the object from pro_*.msg files
- __NOTE:__ this function is intended for use in normal game scripts and overrides the name only once for the same object until reset
macro: sfall.h
- name: obj_is_openable
detail: bool obj_is_openable(object obj)
doc: Returns True if the object is openable (i.e. has an opening/closing animation), False otherwise
macro: sfall.h
