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"

The only action that I could find is the "Control Screensaver" Blueprint Action, this should enable/disable the keep-screen-on functionality on android. Not totally sure if keep-screen-on also disables sleep but I think so.

The code delegates to a platform specific action. On android the following is called:

 AndroidThunkCpp_KeepScreenOn(true);

You can see that for yourself if you right click on the Control Screensaver node and use "Goto Code Definition". Follow the source until you land in the AndroidMisc.cpp file. There, find the method FAndroidMisc::ControlScreensaver.

I don't know if its is possible to modify the first loading of the game in any way by blueprint. You could change the source to call the ControlScreensaver/KeepScreenOn method on the first possible occasion.

Thanks its good but as you said seems we need to call this action during loading which is before event begin play ,and I'm not a programer so i can't get more that what you got , hope UE team can add this as a feature in the engine in the future .

I'm calling the "Control Screensaver" Blueprint Action from a "Event Construct", in a Widget, and it works fine. Screen doesn't turn off.
