Approved for Versions:4.6+

Visual Studio Snippets could be very useful, that’s why I’ve created a public repository with a few examples. Snippets are generated with doxygen style comments.

How to add snippet ?

First of all you have to clone GitHub repository. Then you have two choices:

  1. Method one. Paste .snippet files into: "C:\Users\$user$\Documents\Visual Studio 2013\Code Snippets\Visual C++\My Code Snippets". Then restart VS.
  2. Method two. Open Visual Studio, navigate to TOOLS -> Code Snippets Manager… -> Import… (This allows an Add folder option for easier management)

[4.6 Branch and above] Epic seems to have started initial integration with Branch 4.6 and above. Look on GitHub under "\Engine\extras\VisualStudioSnippets" and follow the Readme file.

How to use snippets ?

Import them and just start typing ue4…

After selecting snippet from the list, hit TAB.

To navigate between highlited fields you can use TAB and SHIFT + TAB. After you enter all names, hit ENTER.
