actor = None just for a fraction of a second.

Hello, I have a function which spawns an Actor, logs inside the function show the actor was successfully spawned, out of the function, right after I called it, I log the actor to see if it's None, and it is None indeed, then in the Tick() function, right after the previous log showed me the actor is None, a log shows me the actor is not None, and it's the same reference of when it was spawned.
That's the code:
MainClass:
Code: Select all
function outer(OtherClass anActor) {
anActor.inner();
Log(anActor.SpawnedActor); // GIVES None.
}
OtherClass:
Code: Select all
var SomeActor SpawnedActor;
function inner() {
SpawnedActor = Spawn(class'SomeActor');
Log(SpawnedActor); // GIVES 'SomeActor0'.
}
function Tick(float Delta) {
Log(SpawnedActor); // ALWAYS GIVES 'SomeActor0'.
}
Notice the 3 logs, the one that gives None is in the middle between the two that give 'SomeActor0'. How is it possible? Can an offset link, link to a wrong offset for a fraction of a second?

Don't define variables with existing 'field' names (variables, functions, states).

Ok well I should admit my variable isn't called "SpawnedActor" but "OIP", how can I know if the name "OIP" has been used in a superclass? (If that's what you're meaning)
EDIT: Ok I just found out something, I think it's cause of concurrency, I made the code like this:
In the called function:
But the logs come out like this:
log1 - None
log3 - None
log2 - Reference
Is it cause of concurrency so?
EDIT 2: The class with the called function, actually has Tick() which call that function too, this must be the problem!
EDIT 3: I commented the call from within Tick(), now it comes out like log1, log2, log3, all three showing None, how can I know why Spawn() failed?

What Higor is telling you is not to use the same name for Functions, States and variables (those are all UFields..).
You're using the name "outer" for a function.. there is already a very special Object variable with this name in every object..

Next time I won't change names just to show it as an example, I wanted to make it easy for you to understand the code flow, but the names are not those I showed you. I edited the prev post right when you were posting this one .o.

EDIT: SOLVED! I knew I would have regret of it when I decided to do it that way, the situation was like this actually, there are 3 classes:
Class 1:
Code: Select all
spawn class2 with Owner = None;
call class2.outer();
set the class2 Owner;
Class 2 - function outer():
Class 3 - function inner():
Code: Select all
if (class2's Owner != None) {spawn OIP;}
log2;
OIP is not spawned cause class2's Owner is None, that's why OIP was not None in the logs from within Tick().
Well it is solved! Thanks everyone for your support
Moral: Sometimes you think the problem is inside the box, when it is actually outside lol.
