`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(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.
* table returned by the above function is like this:
```lua
effect = {
dur = float -- duration of the effect in seconds, may be infinite
timer = float -- how much of the duration (in seconds) has already elapsed
no_particles = bool -- if this is true, no particles signifying this effect will appear
-- player-only fields
hud_index = int -- position in the HUD used by this effect (icon, level, timer) - probably meaningless outside mcl_potions
-- optional fields
factor = float -- power of the effect if the effect uses factor; this may mean different things depending on the effect
step = float -- how often (in seconds) the on_step() function of the effect is executed, if it exists
hit_timer = float -- how much of the step (in seconds) has already elapsed
-- effect-specific fields
-- effects in mcl_potions have their own fields here, for now external effects can't add any here
blocked = bool -- used by conduit power
high = bool -- used by nausea
vignette = int -- handle to the HUD vignette of the effect, used by effects that use one
absorb = float -- "HP" of the absorption effect
waypoints = table -- used by glowing, indexed by player ObjectRef, contains HUD handles for the glowing waypoints
flash = float -- used by darkness, denotes vision range modifier
flashdir = bool -- used by darkness, denotes whether vision range is increasing (or decreasing)
}
```
`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_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`.
