Best place to store "global" variables

Development Programming & Scripting C++

Hi all,

I just got started with UE4 and I’m trying to wrap my head around the C++ aspect of development. I did some level design and modding for UT3 and UDK a couple years back, but UE4 will take some adjustment. :slight_smile:

Anyway, I was wondering about the best way to create a “global” variable in UE4 (I assume an actual global isn’t the best way to do it :smiley: ). More specifically, I’m wondering where I can put world attributes (e.g. time of day, force of gravity, or who the current president is) so that all other classes I write can access them. Any help is appreciated.

Hi,

Take a look at GameState: https://docs.unrealengine.com/latest/INT/Gameplay/Framework/GameState/index.html

Hmm, depends what lifetime they need. GameInstance is created when the engine starts to run and remains until the executable exits, so that is as “global” as you’re going to get.
