API UnitIsVisible

Indicates whether the game client (rather than the player) can see unit.


 * Arguments


 * (String unit)


 * unit : UnitId of the unit


 * Returns


 * vis : Number - 1 if client can see unit, nil if not


 * Details
 * The game client can see objects (including units) that the server has told it to load (and has not yet told it to unload). The server provides objects in a 100-yard radius, but seems to load them in batches.


 * This does not check for line-of-sight, only for game client visibility.
