Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Custom UPROPERTY serializing to DefaultEngine.ini

Hello.

I have a UPROPERTY in one class and I want it to save to DefaultEngine.ini config. In my current setup, the value is properly read from that location (if value was placed in the config manually), but whenever given UPROPERTY changes, it's saved in /Saved/Config/Windows/Engine.ini instead of Config/DefaultEngine.ini.

Is there any way to make it, so the changes are applied to the DefaultEngine.ini config file?

My current setup is as follows.

Header:

 UCLASS(config = Engine, defaultconfig)
 class PROJECT_API UMyObject : public UObject
 {    
      GENERATED_BODY()

      UPROPERTY(config)
      FName Variable;
 }

I'm using 4.12.4 version of the engine.

Thanks in advance.

Product Version: UE 4.12

I managed to do this.

The object on which i was editing the value was CDO (Class Default Object).

Here's the example of how to change variable and save it in defaultengine.ini:

 UMyObject* CDO = GetMutableDefault<UTeamsSettings>();
 if (CDO) // should be always valid but just in case
 {
      CDO->Variable = FName("New value");
      CDO->SaveConfig(CPF_Config, *GetDefaultConfigFilename());
 }

Also, I had to change declaration of Variable a bit (globalconfig had to be changed to config - see OP).
