Created Instance that can change creator's variables?

[giraffeman210]

I am trying to make something where an instance is activated and it creates a different instance. and I need it so the created instance knows the creator. This way when you activate the newly created instance it changes a variable on the instance that created it. Any ideas? Thanks!

with (instance_create())
    ID = other.id;

or

var _id    = instance_create();
    _id.ID = id;

ID now holds the id of the creator instance.

// If you don't need to do anything in the create event
var _newlyCreatedInstance = instance_create_layer(x, y, layer, oSomeObject);
_newlyCreatedInstance.myCreator = id;

// Or have a member function that performs what you need
_newlyCreatedInstance.SetMyCreator(id); // Set the creator and do stuff

// If you really want to be able to access the creator in the objects create event then consider

// Set a global
global.theCreator = id;

// Now oSomeObjects create event can access the global variable 'theCreator'
var _newlyCreatedInstance = instance_create_layer(x, y, layer, oSomeObject);

// Reset the global to undefined
global.theCreator = undefined;

Technically I think 'other' will work in this case to get the id of the creator from the create event. However, that is undocumented behavior.

    _id.ID = id;

ID now holds the id of the creator instance.

How would I access the id now? Say I want to change a variable in the instance that the id belongs to?

Using the dot operator.

ID.x = 10;
