HI everyone.
I am quite a newbie for programming and also Godot

so I just wonder about Godot variable stores the actual object or its pointer reference.

for instance
if i have an object called “SomeObject” and it has a property a = 1, so I assign it to variables item_1 and item_2

var item_1 = SomeObject
var item_2 = SomeObject

# 1

item_2.a = 100
#??? what will be printed 1 or 100 ? 

thanks in advance for your answers.

It will print 100. Objects, Arrays and Dictionaries are passed by reference, while primitive types like int, bool, float, Vector2, Vector3, Transform2D and Transform are passed by value.
