Hello community,
I have an AutoLoad Script “GlobaleVariable.gd” that has two dictionaries dictPersons and dictFriends. Both dictionaries are empty at start and get filled by function. dictPersons by a CSV reading function and dictFriends by values in code. This works good. Both globals are filled.
BUT:
I also assigned some (local) varables on different places in the main script “TestVars.gd” (outside/inside of “func _ready():” ) in the style: onready var test = GlobaleVariable.dictPersons.
I expected, these variables are identical to the global ones (like pointers to same memory address) but they aren’t.
The local variables, that have been assigned to “dictPersons” before the filling function was called, are empty. The one, that was called after, is filled correctly.
I thought: Ok, maybe a lag in the update of the local variables.
BUT:
The variable, that has been assigned to GlobaleVariable.dictFriends before its filling function has been executed, is filled correctly.
Shortform: Why is Test_A1 empty and Test_F1 isn’t.
Has someone an explanation?
