can i open my scripts with visual studio 2013 instead visual studio 2015? how ?
Unreal Engine 4 doesn’t use scripts (in contrary with UE3 with unrealscript). It uses C++ and C# programming languages (well, and a blueprints).
You could edit C++/C# files in any editor, but…
- To build a project ue4 invokes a visual studio tools
- Recent versions of ue4 using C++14 which is only available in VS2015 (no clang yet)
Is there any particular reason for You to use VS2013?
