General Advice:

• Avoid tick at all costs, use event dispatchers and interfaces instead.
• Avoid delay nodes, if you want to delay an action, use timers as they start a new thread rather than sleeping the main game thread.
• Components, components, components, if possible, put functionality into a component rather than having a monolithic "Player Character" class.
• If resorting to a cast, cast to the class closest to the root class. Never cast to a child class where you're not using those child variables, it causes so many headaches when adding anything new to your game.
• Use blueprint function and macro libraries for common functionality as often as possible, don't create potentially reusable functionality in the class you're currently working in. I've noticed it's a lot easier to fall into this pitfall in UE BPs/C++ than in a language like C# or standard C++.
• Now, I could bore you with an entire book about thinking like a programmer... if you prefer. Yeah, I didn't think so.

Game Framework & Class Communication:

This section teaches fundamental concepts for class modularity & communication. Note: tutorials will teach a traditional method of building game logic, but if you're using the gameplay ability system, a lot of those structural concepts will not apply. It is still essential to understand these concepts as they will still be used around and in the gameplay ability system.

This decision fundamentally changes how data is accessed by your UI, so it's wise to apply it across your entire UI implementation if used at all.
