Description

This API defines and applies different Field Of View effects to players via MODIFIERS.

Troubleshooting

In the init.lua file for this module, there is a DEBUG variable at the top that will turn on logging. Use it to see what is going on.

Modifier Definition

def = {
    name = name,
    fov_factor = fov_factor,
    time = time,
    reset_time = reset_time,
    is_multiplier = is_multiplier,
    exclusive = exclusive,
    on_start = on_start,
    on_end = on_end,
}

• Name: The name of the Modifier, used to identify the specific modifier. Case sensitive.
• FOV Factor: A float value defining the FOV to apply. Can be an absolute or percentage, depending on Exclusive and Is_Multiplier.
• Time: A float value defining the number of seconds to take when applying the FOV Factor. Used to smoothly move between FOVs. Use 0 for an immediate FOV Shift. (Transition time.)
• Reset Time: A float value defining the number of seconds to take when removing the FOV Factor. Used to smoothly move between FOVs. Use 0 for an immediate FOV Shift. (Reset transition time.) If not provided, defaults to Time
• Is Multiplier: A bool value used to specify if the FOV Factor is an absolute FOV value or if it should be a percentage of the current FOV. Defaults to true if not defined.
• Exclusive: A bool value used to specify whether the modifier will override all other FOV modifiers. An example of this is how the spy glass sets the FOV to be a specific value regardless of any other FOV effects applied. Defaults to false if not defined.
• On Start: the on_start is a callback function on_start(player) that is called if defined. The parameter player is a ref to the player that had the modifier applied. Called from mcl_fovapi.apply_modifier immediately after the FOV Modifier has been applied.
• On End: the on_end is a callback function on_end(player) that is called if defined. The parameter player is a ref to the player that had the modifier applied. Called from mcl_fovapi.remove_modifier immediately after the FOV Modifier has been removed.

Note: passing incorrect values in the definition will have unintended consequences.

Global MCL_FOVAPI Tables

There are three tables that are accessible via the API. They are registered_modifiers and applied_modifiers.

mcl_fovapi.registered_modifiers has the definitions of all the registered FOV Modifiers. Indexed by Modifier Name. And, mcl_fovapi.applied_modifiers is indexed by the Player Name. It contains the names of all the modifiers applied to the player. The mcl_fovapi.default_fov table is indexed by the Player Name, and contains the Default FOVs of the player from the settings. (Expressed as a value usable in player:set_fov.)

Namespaces

mcl_fovapi is the default API Namespace.

Functions

mcl_fovapi.register_modifier(def)

Used to register a new FOV Modifier for use. Must be called before applying said modifier to a player. See Modifier Definition for what the parameters are.

mcl_fovapi.apply_modifier(player, modifier_name)

Used to apply a registered FOV modifier to a player. Takes a reference to the player and the modifier's name (string).

mcl_fovapi.remove_modifier(player, modifier_name)

Used to remove a specific FOV modifier from a Player. Takes a reference to the player and the modifier's name (string). Removed immediately.

mcl_fovapi.remove_all_modifiers(player)

Used to remove all FOV modifiers from a Player. Takes a reference to the Player. FOV change is instantaneous.
