+### Namespace
+All of the API is defined in the `mcl_potions` namespace.
+
+### Effects
+This section describes parts of the API related to defining and managing effects on players and entities. The mod defines a bunch of effects internally using the same API as described below.
+
+#### Functions
+`mcl_potions.register_effect(def)` – takes an effect definition (`def`) and registers an effect if the definition is valid, and adds the known parts of the definition as well as the outcomes of processing of some parts of the definition to the `mcl_potions.registered_effects` table. This should only be used at load time.
+
+
+`mcl_potions.apply_haste_fatigue(toolcaps, h_fac, f_fac)` – takes a table of tool capabilities (`toolcaps`) and modifies it using the provided haste factor (`h_fac`) and fatigue factor (`f_fac`). The factors default to no-op values.
+
+
+`mcl_potions.hf_update_internal(hand, object)` – returns the `hand` of the `object` updated according to their combined haste and fatigue. **This doesn't change anything by itself!** Manual update of the hand with the hand returned by this function has to be done. This should only be called in situations that are *directly* impacted by haste and/or fatigue, and therefore require an update of the hand.
+
+
+`mcl_potions.update_haste_and_fatigue(player)` – updates haste and fatigue on a `player` (described by an ObjectRef). This should be called whenever an update of the haste-type and fatigue-type effects is desired.
+
+
+`mcl_potions._reset_haste_fatigue_item_meta(player)` – resets the item meta changes caused by haste-type and fatigue-type effects throughout the inventory of the `player` described by an ObjectRef.
+
+
+`mcl_potions._clear_cached_effect_data(object)` – clears cashed effect data for the `object`. This shouldn't be used for resetting effects.
+
+
+`mcl_potions._reset_effects(object, set_hud)` – actually resets the effects for the `object`. It also updates HUD if `set_hud` is `true` or undefined (`nil`).
+
+
+`mcl_potions._save_player_effects(player)` – saves all effects of the `player` described by an ObjectRef to metadata.
+
+
+`mcl_potions._load_player_effects(player)` – loads all effects from the metadata of the `player` described by an ObjectRef.
+
+
+`mcl_potions._load_entity_effects(entity)` – loads all effects from the `entity` (a LuaEntity).
+
+
+`mcl_potions.has_effect(object, effect_name)` – returns `true` if `object` (described by an ObjectRef) has the effect of the ID `effect_name`, `false` otherwise.
+
+
+`mcl_potions.get_effect(object, effect_name)` - returns a table containing values of the effect of the ID `effect_name` on the `object` if the object has the named effect, `false` otherwise.
+
+
+`mcl_potions.get_effect_level(object, effect_name)` – returns the level of the effect of the ID `effect_name` on the `object`. If the effect has no levels, returns `1`. If the object doesn't have the effect, returns `0`. If the effect is not registered, returns `nil`.
+
+
+`mcl_potions.get_total_haste(object)` – returns the total haste of the `object` (from all haste-type effects).
+
+
+`mcl_potions.get_total_fatigue(object)` – returns the total fatigue of the `object` (from all fatigue-type effects).
+
+
+`mcl_potions.clear_effect(object, effect)` – attempts to remove the effect of the ID `effect` from the `object`. If the effect is not registered, logs a warning and returns `false`. Otherwise, returns `nil`.
+
+
+`mcl_potions.make_invisible(obj_ref, hide)` – makes the object going by the `obj_ref` invisible if `hide` is true, visible otherwise.
+
+
+`mcl_potions.register_generic_resistance_predicate(predicate)` – registers an arbitrary effect resistance predicate. This can be used e.g. to make some entity resistant to all (or some) effects under specific conditions.
+
+* `predicate` – `function(object, effect_name)` - return `true` if `object` resists effect of the ID `effect_name`
+
+
+`mcl_potions.give_effect(name, object, factor, duration, no_particles)` – attempts to give effect of the ID `name` to the `object` with the provided `factor` and `duration`. If `no_particles` is `true`, no particles will be emitted from the object when under the effect. If the effect is not registered, target is invalid (or resistant), or the same effect with more potency is already applied to the target, this function does nothing and returns `false`. On success, this returns `true`.
+
+
+`mcl_potions.give_effect_by_level(name, object, level, duration, no_particles)` – attempts to give effect of the ID `name` to the `object` with the provided `level` and `duration`. If `no_particles` is `true`, no particles will be emitted from the object when under the effect. This converts `level` to factor and calls `mcl_potions.give_effect()` internally, returning the return value of that function. `level` equal to `0` is no-op.
+
+
+`mcl_potions.healing_func(object, hp)` – attempts to heal the `object` by `hp`. Negative `hp` harms magically instead.
+
+
+#### Deprecated functions
+**Don't use the following functions, use the above API instead!** The following are only provided for backwards compatibility and will be removed later. They all call `mcl_potions.give_effect()` internally.
+
+* `mcl_potions.strength_func(object, factor, duration)`
+* `mcl_potions.leaping_func(object, factor, duration)`
+* `mcl_potions.weakness_func(object, factor, duration)`
+* `mcl_potions.swiftness_func(object, factor, duration)`
+* `mcl_potions.slowness_func(object, factor, duration)`
+* `mcl_potions.withering_func(object, factor, duration)`
+* `mcl_potions.poison_func(object, factor, duration)`
+* `mcl_potions.regeneration_func(object, factor, duration)`
+* `mcl_potions.invisiblility_func(object, null, duration)`
+* `mcl_potions.water_breathing_func(object, null, duration)`
+* `mcl_potions.fire_resistance_func(object, null, duration)`
+* `mcl_potions.night_vision_func(object, null, duration)`
+* `mcl_potions.bad_omen_func(object, factor, duration)`
+
+
+
+#### Tables
+`mcl_potions.registered_effects` – contains all effects that have been registered. You can read from it various data about the effects. You can overwrite the data and alter the effects' definitions too, but this is discouraged, i.e. only do this if you really know what you are doing. You shouldn't add effects directly to this table, as this would skip important setup; instead use the `mcl_potions.register_effect()` function, which is described above.
+
+#### Internally registered effects
+You can't register effects going by these names, because they are already used:
+* `invisibility`
+* `poison`
+* `regeneration`
+* `strength`
+* `weakness`
+* `weakness`
+* `dolphin_grace`
+* `leaping`
+* `slow_falling`
+* `swiftness`
+* `slowness`
+* `levitation`
+* `night_vision`
+* `darkness`
+* `glowing`
+* `health_boost`
+* `absorption`
+* `fire_resistance`
+* `resistance`
+* `luck`
+* `bad_luck`
+* `bad_omen`
+* `hero_of_village`
+* `withering`
+* `frost`
+* `blindness`
+* `nausea`
+* `food_poisoning`
+* `saturation`
+* `haste`
+* `fatigue`
+* `conduit_power`
+
+#### Constants
+`mcl_potions.LONGEST_MINING_TIME` – longest mining time of one block that can be achieved by slowing down the mining by fatigue-type effects.
+
+`mcl_potions.LONGEST_PUNCH_INTERVAL` – longest punch interval that can be achieved by slowing down the punching by fatigue-type effects.
+
+#### Effect Definition
+```lua
+def = {
+-- required parameters in def:
+    name = string -- effect name in code (unique ID) - can't be one of the reserved words ("list", "heal", "remove", "clear")
+    description = S(string) -- actual effect name in game
+-- optional parameters in def:
+    get_tt = function(factor) -- returns tooltip description text for use with potions
+    icon = string -- file name of the effect icon in HUD - defaults to one based on name
+    res_condition = function(object) -- returning true if target is to be resistant to the effect
+    on_start = function(object, factor) -- called when dealing the effect
+    on_load = function(object, factor) -- called on_joinplayer and on_activate
+    on_step = function(dtime, object, factor, duration) -- running every step for all objects with this effect
+    on_hit_timer = function(object, factor, duration) -- if defined runs a hit_timer depending on timer_uses_factor value
+    on_end = function(object) -- called when the effect wears off
+    after_end = function(object) -- called when the effect wears off, after purging the data of the effect
+    on_save_effect = function(object -- called when the effect is to be serialized for saving (supposed to do cleanup)
+    particle_color = string -- colorstring for particles - defaults to #3000EE
+    uses_factor = bool -- whether factor affects the effect
+    lvl1_factor = number -- factor for lvl1 effect - defaults to 1 if uses_factor
+    lvl2_factor = number -- factor for lvl2 effect - defaults to 2 if uses_factor
+    timer_uses_factor = bool -- whether hit_timer uses factor (uses_factor must be true) or a constant value (hit_timer_step must be defined)
+    hit_timer_step = float -- interval between hit_timer hits
+    damage_modifier = string -- damage flag of which damage is changed as defined by modifier_func, pass empty string for all damage
+    dmg_mod_is_type = bool -- damage_modifier string is used as type instead of flag of damage, defaults to false
+    modifier_func = function(damage, effect_vals) -- see damage_modifier, if not defined damage_modifier defaults to 100% resistance
+    modifier_priority = integer -- priority passed when registering damage_modifier - defaults to -50
+    affects_item_speed = table
+-- -- if provided, effect gets added to the item_speed_effects table, this should be true if the effect affects item speeds,
+-- -- otherwise it won't work properly with other such effects (like haste and fatigue)
+-- -- -- factor_is_positive - bool - whether values of factor between 0 and 1 should be considered +factor% or speed multiplier
+-- -- --   - obviously +factor% is positive and speed multiplier is negative interpretation
+-- -- --   - values of factor higher than 1 will have a positive effect regardless
+-- -- --   - values of factor lower than 0 will have a negative effect regardless
+}
+```
+
+### HP Hudbar Modifiers
+This part of the API allows complex modification of the HP hudbar. It is mainly required here, so it is defined here. It may be moved to a different mod in the future.
+
+#### Functions
+`mcl_potions.register_hp_hudbar_modifier(def)` – this function takes a modifier definition (`def`, described below) and registers a HP hudbar modifier if the definition is valid.
+
+#### HP Hudbar Modifier Definition
+```lua
+def = {
+-- required parameters in def:
+    predicate = function(player) -- returns true if player fulfills the requirements (eg. has the effects) for the hudbar look
+    icon = string -- name of the icon to which the modifier should change the HP hudbar heart
+    priority = signed_int -- lower gets checked first, and first fulfilled predicate applies its modifier
+}
+```
+
+### Potions
+Magic!
+
+#### Functions
+`mcl_potions.register_potion(def)` – takes a potion definition (`def`) and registers a potion if the definition is valid, and adds the known parts of the definition as well as the outcomes of processing of some parts of the definition to the `mcl_potions.registered_effects` table. This, depending on some fields of the definition, may as well register the corresponding splash potion, lingering potion and tipped arrow. This should only be used at load time.
+
+`mcl_potions.register_splash(name, descr, color, def)` – registers a splash potion (item and entity when thrown). This is mostly part of the internal API and probably shouldn't be used from outside, therefore not providing exact description. This is used by `mcl_potions.register_potion()`.
+
+`mcl_potions.register_lingering(name, descr, color, def)` – registers a lingering potion (item and entity when thrown). This is mostly part of the internal API and probably shouldn't be used from outside, therefore not providing exact description. This is used by `mcl_potions.register_potion()`.
+
+`mcl_potions.register_arrow(name, desc, color, def)` – registers a tipped arrow (item and entity when shot). This is mostly part of the internal API and probably shouldn't be used from outside, therefore not providing exact description. This is used by `mcl_potions.register_potion()`.
+
+#### Tables
+`mcl_potions.registered_potions` – contains all potions that have been registered. You can read from it various data about the potions. You can overwrite the data and alter the definitions too, but this is discouraged, i.e. only do this if you really know what you are doing. You shouldn't add potions directly to this table, because they have to be registered as items too; instead use the `mcl_potions.register_potion()` function, which is described above. Some brewing recipes are autofilled based on this table after the loading of all the mods is done.
+
+#### Constants
+* `mcl_potions.POTENT_FACTOR = 2`
+* `mcl_potions.PLUS_FACTOR = 8/3`
+* `mcl_potions.INV_FACTOR = 0.50`
+* `mcl_potions.DURATION = 180`
+* `mcl_potions.DURATION_INV = mcl_potions.DURATION * mcl_potions.INV_FACTOR`
+* `mcl_potions.DURATION_POISON = 45`
+* `mcl_potions.II_FACTOR = mcl_potions.POTENT_FACTOR` – **DEPRECATED**
+* `mcl_potions.DURATION_PLUS = mcl_potions.DURATION * mcl_potions.PLUS_FACTOR` – **DEPRECATED**
+* `mcl_potions.DURATION_2 = mcl_potions.DURATION / mcl_potions.II_FACTOR` – **DEPRECATED**
+* `mcl_potions.SPLASH_FACTOR = 0.75`
+* `mcl_potions.LINGERING_FACTOR = 0.25`
+
+#### Potion Definition
+```lua
+def = {
+-- required parameters in def:
+    name = string, -- potion name in code
+-- optional parameters in def:
+    desc_prefix = S(string), -- part of visible potion name, comes before the word "Potion"
+    desc_suffix = S(string), -- part of visible potion name, comes after the word "Potion"
+    _tt = S(string), -- custom tooltip text
+    _dynamic_tt = function(level), -- returns custom tooltip text dependent on potion level
+    _longdesc = S(string), -- text for in=game documentation
+    stack_max = int, -- max stack size -  defaults to 1
+    image = string, -- name of a custom texture of the potion icon
+    color = string, -- colorstring for potion icon when image is not defined - defaults to #0000FF
+    groups = table, -- item groups definition for the regular potion, not splash or lingering -
+--   - must contain _mcl_potion=1 for tooltip to include dynamic_tt and effects
+--   - defaults to {brewitem=1, food=3, can_eat_when_full=1, _mcl_potion=1}
+    nocreative = bool, -- adds a not_in_creative_inventory=1 group - defaults to false
+    _effect_list = {, -- all the effects dealt by the potion in the format of tables
+-- -- the name of each sub-table should be a name of a registered effect, and fields can be the following:
+        uses_level = bool, -- whether the level of the potion affects the level of the effect -
+-- -- --   - defaults to the uses_factor field of the effect definition
+        level = int, -- used as the effect level if uses_level is false and for lvl1 potions - defaults to 1
+        level_scaling = int, -- used as the number of effect levels added per potion level - defaults to 1 -
+-- -- --   - this has no effect if uses_level is false
+        dur = float, -- duration of the effect in seconds - defaults to mcl_potions.DURATION
+        dur_variable = bool, -- whether variants of the potion should have the length of this effect changed -

+-- -- --   - if at least one effect has this set to true, the potion has a "plus" variant
+        effect_stacks = bool, -- whether the effect stacks - defaults to false
+    }
+    uses_level = bool, -- whether the potion should come at different levels -
+--   - defaults to true if uses_level is true for at least one effect, else false
+    drinkable = bool, -- defaults to true
+    has_splash = bool, -- defaults to true
+    has_lingering = bool, -- defaults to true
+    has_arrow = bool, -- defaults to false
+    has_potent = bool, -- whether there is a potent (e.g. II) variant - defaults to the value of uses_level
+    default_potent_level = int, -- potion level used for the default potent variant - defaults to 2
+    default_extend_level = int, -- extention level (amount of +) used for the default extended variant - defaults to 1
+    custom_on_use = function(user, level), -- called when the potion is drunk, returns true on success
+    custom_effect = function(object, level, plus), -- called when the potion effects are applied, returns true on success
+    custom_splash_effect = function(pos, level), -- called when the splash potion explodes, returns true on success
+    custom_linger_effect = function(pos, radius, level), -- called on the lingering potion step, returns true on success
+}
+```
+
+### Brewing

+
+#### Functions

+`mcl_potions.register_table_modifier(ingr, modifier)` – registers a brewing recipe altering the potion using a table; this is supposed to substitute one item with another
+
+`mcl_potions.register_inversion_recipe(input, output)` – what it says
+
+`mcl_potions.register_meta_modifier(ingr, mod_func)` – registers a brewing recipe altering the potion using a function; this is supposed to be a recipe that changes metadata only

+Add a status effect to yourself. Arguments: <effect>: name of status effect. Passing "list" as effect name lists available effects. Passing "heal" as effect name heals (or harms) by amount designed by the next parameter. Passing "clear" as effect name removes all effects. Passing "remove" as effect name removes the effect named by the next parameter. <duration>: duration in seconds. Passing "INF" as duration makes the effect infinite. (<heal-amount>: amount of healing when the effect is "heal", passing a negative value subtracts health. <effect>: name of a status effect to be removed when using "remove" as the previous parameter.) <level>: effect power determinant, bigger level results in more powerful effect for effects that depend on the level (no changes for other effects), defaults to 1, pass F to use low-level factor instead. <factor>: effect strength modifier, can mean different things depending on the effect, no changes for effects that do not depend on level/factor. NOPART at the end means no particles will be shown for this effect.=Nadaj efekt statusu dla samego siebie. Argumenty: <ID-efektu>: nazwa efektu statusu (po angielsku). Przekazanie "list" jako nazwa efektu wypisuje dostępne nazwy efektów. Przekazanie "heal" jako nazwa efektu leczy (albo krzywdzi) o ilość określoną następnym parametrem. Przekazanie "clear" jako nazwy efektu usuwa wszystkie efekty. Przekazanie "remove" jako nazwy efektu usuwa efekt określony następnym parametrem. <czas-trwania>: czas trwania w sekundach. Przekazanie "INF" jako czas trwania czyni efekt nieskończonym. (<ilość-leczenia>: ilość leczenia kiedy ID-efektu to "heal", przekazanie liczby ujemnej zabiera zdrowie. <ID-efektu>: nazwa efektu statusu do usunięcia używając "remove" jako poprzedniego parametru.) <poziom>: wyznacznik siły efektu, wyższy poziom skutkuje potężniejszym efektem prze efektach zależnych od poziomu (brak zmiany przy pozostałych), domyślnie 1, przekaż F żeby użyć niskopoziomowego współczynnika zamiast poziomu. <współczynnik>: modyfikator siły efektu, może oznaczać różne rzeczy dla różnych efektów, nie wpływa na efekty, które nie zależą od poziomu/współczynnika. NOPART na końcu oznacza, że cząsteczki nie będą wyświetlane wokół ciebie dla tego efektu.

+Add a status effect to yourself. Arguments: <effect>: name of status effect. Passing "list" as effect name lists available effects. Passing "heal" as effect name heals (or harms) by amount designed by the next parameter. Passing "clear" as effect name removes all effects. Passing "remove" as effect name removes the effect named by the next parameter. <duration>: duration in seconds. Passing "INF" as duration makes the effect infinite. (<heal-amount>: amount of healing when the effect is "heal", passing a negative value subtracts health. <effect>: name of a status effect to be removed when using "remove" as the previous parameter.) <level>: effect power determinant, bigger level results in more powerful effect for effects that depend on the level (no changes for other effects), defaults to 1, pass F to use low-level factor instead. <factor>: effect strength modifier, can mean different things depending on the effect, no changes for effects that do not depend on level/factor. NOPART at the end means no particles will be shown for this effect.=
