Help & Resources for Unreal Engine 4

So, you’re stuck? Me too, it happens a lot more than I’d like to admit.

Other than searching the web in general, luckily there are a bunch of places to get help for Unreal Engine.

Search the engine source

If you’re not sure how to do something, whether a function exists for it, or how to use a function you’ve found, I often find the quickest way is to search the engine source code. This is my first port of call, and I find it easiest as I’m usually in Visual Studio anyway.

In Visual Studio, press Control + Shift + F to do a plain-text search, make sure “Entire Solution” is selected so it seaches both your project and the UE4 Engine project.

Use 'Find in Files' to search for use cases

Searching for uses of UGameUserSettings can help you to work out how to use the class.

Unreal Slackers Discord

The Unreal Slackers Discord server is an incredibly helpful and friendly place. If you have C++ or UMG questions in particular, you will probably get a reply.

Of course it’s only people helping out each other in their free time, so don’t be too demanding :)

Engine Feature Samples

In the Epic Games Launcher, under Unreal Engine there is a Learn tab that has a fantasty selection of example projects and demos to learn from.

If you are new to Unreal Engine 4, I recommend starting with Content Examples. For a more complete example to learn from, scroll down further and try the Action RPG game sample.

UE4 AnswerHub

The Unreal Engine 4 AnswerHub is a Stack Overflow-style question and answer forum that anyone can use.

Unreal Engine Community Wiki

Newly moved, the Unreal Community Wiki has a lot of code samples and tutorials. Check out the Legacy area for a lot of good content.

Unreal Engine Forums

I haven’t used the Unreal Engine Forums for asking questions very often, but they are a great repository of knowledge.

Searching “Unreal Engine 4” on GitHub might not be a great way to answer questions, but I’ve found it really useful for finding interesting code snippets, new ways of doing things, plugins and more.

Definitely worth checking out every month or so to see what pops up.

Similarly, the Unreal Marketplace has a huge number of free code plugins that can be interesting to learn from.

Unreal Engine 4 Documentation

There’s a reason the official documentation is this far down the list. It can be useful to get a high-level overview of a system but if you’re writing C++ pretty soon it’s better to start looking at the engine source or examples of usage.
