#### 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
|
|
```lua
|
|
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.)
|
|
Defaults to `time` if not defined.
|
|
* 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.
|
|
|
|
#### 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.
