No problem. A fantastic youtube channel to follow is: https://www.youtube.com/channel/UCOVfF7PfLbRdVEm0hONTrNQ
He does a series called “WTF is?” and does detailed breaks downs of nodes and features in Ue4. This is an excellent way to learn Ue4 BPs, since he has such informative and pure breakdowns of features. It teaches you how to make your own Blueprints well and pick up good habits.
As opposed to watching tutorials. Most Youtube tutorials are really bad and will have you picking up nasty habits that make it hard to learn at later levels. If you follow Mathew’s videos, you’ll be on your way to making your own intuitive games and features.
