|index||The index of the object to change.|
|pers||Whether the object should be flagged as persistent (true) or not (false).|
With this function you can set the persistence of a specific
object. A persistent object is "carried over" from room to room and
maintains its properties at all times (for more information on
persistence see Defining
Objects). Setting the persistence of the object means that all
instances of this object that are created after the persistence
has been changed will be created persistent, while instances
that are already in the room may not be affected.
Please note that this is not an instance function! You can set the persistent flag of individual instances using the persistent variable and so have ten instances all flagged as persistent even though the object in question has the flag set to false in the IDE, and even if you change the persistent flag of the object to true using this function, all instances that currently in the room will remain as they were, and only instances created after calling the function will start with persistent flagged as true.
if room == rm_final object_set_persistent(obj_Player, 0); instance_create_layer(32, 32, "Instances", obj_Player);
The above code checks to see in which room the instance is currently in and if it is in the specified "rm_final" then it sets the persistence of the object "obj_Player" to false and then creates the instance.
