Strange nullreference exception?

Unity Engine
1

Heya,

It is about the panel_load_menu.
All three panels are children of a Canvas.

During the For…Next it is found and assigned.
It is also set to SetActive(false) without any problem and I can with a button set it active and false.
But the compiler keeps telling me I have a nullreference error to an object that is not null?

I can compile the code, start playmode and even Build and Run and turn the panel On and Off,
yet even in debug mode of the build I get the error message

Why?

GameObject[] child = new TargetChildObjects("canvas_main_menu(Clone)").targetchildobjectsArray;
        for(int i = 0; i < child.Length; i++)
        {
            if (child[i].name == "panel_main_menu") { panel_main_menu = child[i]; }
            if (child[i].name == "panel_load_menu") { panel_load_menu = child[i]; }
            if (child[i].name == "panel_newplayer_menu") { panel_newplayer_menu = child[i]; }
        }
            panel_load_menu.gameObject.SetActive(false); //<= Error points to this line
            panel_newplayer_menu.gameObject.SetActive(false);// <= Why not to this one.

ps: my first code was just 'panel_load_menu.SetActive(false) ’ but it gave me the same error

Compilers don’t

I believe that’ll be the runtime not the compiler. But who says the unstated object is “not null”, you? I’m siding with the runtime :wink:

Anyway you didn’t give the full error but going to gamble and say that it’s “new TargetChildObjects(“canvas_main_menu(Clone)”).targetchildobjectsArray;” that at least once returns null early in your game’s execution. Likely this code is being called before it has been initialised?

Ah ‘Terminology’. “So my runtime kept telling me.” (sounds strange though to say my runtime. But yes ‘runtime error’ I know Xd)
But that aside…

But Found the solution.
Had to do with nested levels of children in the prefab and was looking for children of…
I just skipped it and am looking for ALL gameobjects,
But at least it finds it and assigns it.

Thanks tho
