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"

iOS in-app purchases not working when deploying from windows

Engine version is 4.6.1

There seems to be an issue with making in-app purchases via Blueprint on iOS. At least when deploying from Windows. I have not tested it when deploying from a Mac.

I have used the 'Make in-app purchase' node in Blueprint with a correct product identifier and a development provisioning profile. It always executes the failure pin, in the device log it shows the following error message:

UInAppPurchaseCallbackProxy::Trigger - In-App Purchases are not supported by Online Subsystem

Product Version: Not Selected

It seems like IAP have not been enabled in your engine config file.

if you add the following to your projects DefaultEngine.ini


This will enable IAP for the IOS subsystems.

Hey Terence,

Where exactly do I find the "projects DefaultEngine.ini"? Is it in the project settings of my game? Or would I find it in the Unreal Engine file folders on my PC?

Hey Mr Moyo, you should have really opened a new question, but I'll answer here anyway.

The DefaultEngine.ini file I mentioned lives inside [YourGameFolder]/Config
