Unreal Engine’s TArray is a powerful and flexible container that allows you to manage dynamic arrays in your code. One of its lesser-known yet incredibly useful features is the ability to specify custom allocators. These allocators determine how the memory for the array is allocated and managed, which can have a significant impact on performance, especially in memory-constrained environments.

Lambdas, or anonymous functions, in Unreal Engine can be very useful for writing concise and flexible code. However, they come with certain dangers, particularly when dealing with the lifetime of objects and capturing variables by reference. Here’s why:

Inheritance in object-oriented programming (OOP) is a fundamental concept that is deeply embedded in the design of Unreal Engine, and in many cases, it’s an elegant and powerful tool. However, like any tool, it can be overused, leading developers into a trap that can complicate development and maintenance in the long run.

You’ve probably heard the argument before: “C++ is better than Blueprint.” Often, this comes from people who are new to using C++ in Unreal Engine and are riding the peak of the Dunning-Kruger effect.

Buffers are simply containers of bytes that can store raw data using memory offsets. Understanding how to effectively manage these buffers is essential for tasks like serialization, deserialization, and data storage.
