How to Get all the Actors of a Class. Difference Between Pure & Impure Functions. Tutorial Part 15
1Hello and welcome to this lesson which is all about getting actors of a particular class in this lesson, we're going to learn how we can get all the actors of a particular class that exists at a level. And we're going to learn all about arrays and how we can cool functions on them okay.
So in the previous lesson, we started coding this a win level volume that we'll use as a trigger point for completing our level when the player does it. We wanted to run some code that checks if there are any crystals remaining in our level and if no crystals remain the game will load the next level.
This lesson is about pure and impure functions.
In this lesson, we're going to learn about the difference between these functions and we're also going to learn about the pure concept functions.
About me:
I've been making films and doing visual effects on indie films for over 15 years. When I discovered Unreal Engine 4 I was blown away by its realistic real-time rendering engine! I immediately saw that Unreal Engine (UE4) was a game changer and that it had now become possible for a small studio consisting of a few artists to pull off a Hollywood-quality feature-length animated film!
In the past it would take hours, if not days, to render each frame of an animation, which made it impossible for an independent artist to complete a full-length film. It would literally take years to render all the frames of a movie!
