Accessing a table in a list of subclasses (unity)

Hello, i'm trying to change a value of a table during runtime. I have a unity object called manager that is the main, which in turn contains a class called unit, unit contains a list with costumes, along with all the options in a table, where of inside there is a simple bool which i'd like to change from ALLOWED to DISABLED and vice versa, however when i try to access this during runtime it tells me that the object I try access doesn't exit even if i know it's there and, simplified it's something like this

var example = Manager.unit.costumeMap[0];
                    example.costumeTable.usingType = Manager.costumeTable.USING_TYPE.ALLOWED;

var example = Manager.unit.costumeMap[0];
                    example.costumeTable.usingType = Manager.costumeTable.USING_TYPE.ALLOWED;

What I doing wrong?

Really hard to say without seeing the actual code, but if it's telling you some object doesn't exist, I'd wager you are mistaken in thinking that it does 😄 Have you tried setting a breakpoint and checking the values at each step? Apparently something isn't properly initialized when you think it should be.

some object in the chain must be null you have to check for nulls how you check that depends on whether it's a unity object or a simple object

What's the difference between checking them for nulls?

Unity overloads null in some weird ways Where x == null might be true, but x is null might be false

Anton•2y ago

x == null checks if x has been destroyed, or isn't assigned

Thanks so much I will see if doing those checks helps me
