[SOLVED]SetActive/Json not working in Build Mode

Hello !
I'm fairly new to programming, and i have an issue with a project.
I have a button that launches a method that does a bunch of things and finally activates another GameObject.
That GameObject is declared as public and then linked correctly in the inspector at Start().

That method also activates another GameObject.
In both cases it is through:
TheGameObject.SetActive(true);
Both GameObjects are linked correctly through the inspector.

In editor mode, it works perfectly, both objects are shown when i click the button, but when i build the project, only one of them works..
I've tried a tons of stuff and really can't understand what's the issue, i have also looked online and i can't find a similar case with a right answer.

If anyone know what could be the issue here that'd be great :/
cheers

For thoses who have problem with loading json when they build their game.

Application.DataPath, in unity editor, leads to the assets folder
When the game is built, Application.DataPath leads to the root of your game, so you need to create a data folder in your build folder, and put your json files there.

Ex:
Create a Data folder and put your json file(s) in it:
GameName/Data/MyJsonFile.json

And when you load in your script:
string myPath = "/Data/MyJsonFile.json";
filePath = Application.DataPath + myPath;

 

What does the player log say?

hi, thanks for your response,
i'm not sure which document to find here, there is no indication concerning windows10.
I only have an editor.log found through the console(open editor log).
When i launch the build it doesn't crash. Can i access the logs through the build folder ?

 

This is the editor log

 

Not talking about the editor log. I'm talking about the log your standalone build produces when it runs (the build you say is having the problem). That log may be reporting some null reference error not seen in the editor, or something along those lines.

My guess would be the log is stored in Windows 10 in the same location as Windows 7.
C:\Users\username\AppData\LocalLow\CompanyName\ProductName\output_log.txt

Note that it is in a hidden folder. Username would be your username in Windows, and CompanyName\ProductName would be what you told Unity in the project settings.

If you're still having trouble finding the log, you can force the log to whatever location you want with the -logFile command line argument when you launch your standalone build.

https://docs.unity3d.com/Manual/CommandLineArguments.html

 

I think it's this one, company name was "DefaultCompany" since i don't recall having set one.

Indeed there is a NullReferenceException here !

Gonna check this right now

 

Yup, i think know what's going on, i just don't know how to fix it.
I have a Json file and it's not being loaded apparently..

I don't know why, but now i have a console appearing in the bottom left of my screen when i launch my build.

It says :
NullReferenceException: Object reference not set to an instance of an object
at CardsManager.PickRandomCard () [0x00002] in E:\Unity_Projects\Floating Islands\Assets\Scripts\Cards\CardsManager.cs:50
at EventManager.GenerateEvents () [0x00013] in E:\Unity_Projects\Floating Islands\Assets\Scripts\EventManager.cs:80

Here is the related code:


[EventManager.cs:80]:
private Card currentCard;
...
public void GenerateEvents()//Launch the next event
{
calendar.NewWeek();//Updates the week/season/moon cycle

//Chooses a random general Event
currentCard = cardsManager.PickRandomCard();//This returns a random card

---------------------------------------------------------------------------------------------------------------------
[CardsManager.cs:50]:
//This returns a random card
public Card PickRandomCard()
{
int currentId;
do
{
currentId = Random.Range(0, cards.Length);//THIS IS THE LINE 50 (the problematic one)
if (cards[currentId].enabled)
{
break;
}
} while (true);
return cards[currentId];
}

---------------------------------------------------------------------------------------------
I have a Json file that has a
Public class Card

That's why the return type here is Card.

 

I have narrowed it a little, seems it is the cards.Length that is the problem.
It loads the json fine in the editor, but seems it doesn't when i build it..

This is how i load the json :

private string communEventsPath = "/Resources/Json/CommunEventsJson.json";

public void LoadData()
{
string filePath = Application.dataPath + communEventsPath;

if (File.Exists(filePath))
{
string dataAsJson = File.ReadAllText(filePath);
dataAsJson = "{\"Items\":" + dataAsJson + "}";
cards = JsonHelper.FromJson<Card>(dataAsJson);
}
}

I have already tried with Resources.Load, doesn't change anything, and i couldn't managed to load it with TextAsset. but everything is correctly loaded in the editor anyway :/

 

string myPath = "/Data/ItemsData.json";
string filePath = Application.dataPath + myPath;
json = File.ReadAllText(filePath);
gameData = JsonUtility.FromJson<GameData>(json);
print(gameData.Items.Count);

not working at all in windows build :'( plz help

 

If any of you are still having issues with this. Add the JSON file to your gameName_Data folder and it should work.
Then you do not need to change the filepath either

thanks for posting a solution as well. one question I have. Will this solution work also for published games, i.e. let's say somebody downloads the game to their device, will unity build include these json file as well? thanks in advance.

 

Hi o_farzaliyev,

How does one go about doing that? Would, after building the game for Windows, go to the folder that the game is built to & create a new folder there?
