There are a bunch of youtube videos, tutorial etc. online, but we recommend having a look at the [Unreal's learning courses](https://www.unrealengine.com/en-US/onlinelearning-courses) or the [content examples](https://docs.unrealengine.com/en-US/Resources/ContentExamples/index.html) in the [Unreal Engine documentation](https://docs.unrealengine.com/en-US/index.html). Furthermore, the [Unreal Engine 4. x Scripting with C++ Cookbook](https://ebookcentral.proquest.com/lib/rwthaachen-ebooks/detail.action?docID=5744451)[link only works from within RWTH Aachen network only] may provide some helpful insight.
