Description
Welcome to Unreal Engine 5 C++ Climbing System, in this course, you’ll learn how to build a robust climbing system completely from scratch with a deep understanding of how to handle the climb physics, create climb locomotion, climb up and down the ledge, hand and leg IK using control rig, vaulting mechanics, hopping capabilities and a range of other exciting features for a robust climbing experience.
In the first section, we’ll look into how we can handle the movement for our climbing , and start with a new enhanced input with a custom movement component to handle the basic climbing logic. Then we’ll go over how to use different traces to get hold of all the climbable surface info we need, and handle all the physics code needed in order for us to move our character in a custom movement mode. Once we have a working physics, we’re gonna process all the climbable surface info and calculate the velocity and rotation for our climbing.
In second section, we’re going to take care of climbing up, climbing down, climbing to the left, climbing to the right, climb up the ledge, climb down the ledge, enter and exit the climb state. We’ll begin with a charcter anim instance class in C++ and rebuilding our existing animation blueprint. Then we’ll go through the mixamo animation pipeline and look at how we can make use of mixamo converter to retarget animation. Next, we’ll handle the climb locomotion and create our own algorithms to check if we have reached the floor or the ledge.
In the third section, we’ll build a control rig for our hand and leg IK to fix the placement issue when we are climbing, and we’ll dive into motion warping and enhanced input system to implement features like vaulting and hopping. We’ll start with a handy climb IK trace function in our control rig, and dynamically adjust the position of our hands and feet based on the surface. Then we’ll go into motion warping and create more algorithms to check which surface is vaultable, and dynamically set our target point during runtime. After we have fully functional vaulting mechanics, we’ll dive deep into enhanced input system and look at how we can use it to create a two key action that only be triggered during climbing.
Who this course is for:
- Learners who want to create climbing system
- Learners who want to understand vector math
- Learners who want to use control rig for animations
- Learners who want to write clean, extendable code
Instructor
When I started my career as a technical artist, I was driven by a deep desire to make a significant difference in the work I was doing. Specifically, I wanted to help my co-workers enhance their work efficiency and productivity within the Unreal engine. Leveraging my prior experience as a teacher, I discovered my knack for simplifying intricate concepts and explaining them in a way that was accessible to anyone willing to learn.
As my aspirations evolved and I contemplated becoming an online instructor, those around me frequently asked, "What kind of instructor do you envision yourself becoming?"
In my view, I firmly believe that no subject is too daunting when you have a knowledgeable instructor who can guide you through each and every step. By employing a clear, step-by-step approach, anyone can acquire mastery in their desired area, including Unreal.
That is precisely the kind of instructor I aspire to be—an instructor who empowers learners by providing comprehensive guidance and enabling them to confidently navigate their Unreal journey.
