# Can you use common Datastructures in UE?

I just saw that you normally use Unreal engines own data structures when you code scripts.

Why is this are those better ? Can you also use the common c++ datastructures ( vector... ) or are you forced to use the UE ones ?

• "Can you use..." have you tried? What results did you observe? Apr 28 at 16:42

• Another thing to mention is that standard c++ classes like vector are implemented in OS-specific ways, eg visual c runtime dll on Windows. Unreal can target many platforms, including PC, XBox, Switch... There may not be a standard library implementation on those platforms
