[Rookiss University] UE5 Lyra Clone Coding (Haker&Liu)

Conversation loops, tool calling, permissions, prompt assembly — learn the core principles of Claude Code by visualizing them through 3D interactive materials. Translate the structure you understood from the materials directly into code to complete your very own 'Mini Claude Code (Harness)'.

This is an introductory course where you learn the core concepts of Claude Code through a 3D office analogy. From hiring a single robot in an empty office, giving it a brain and a heart, equipping it with tools, permissions, and memory, to eventually having multiple robots work together as a team—each concept unfolds as an office scene. You will master every concept by interacting with the digital course materials and complete your learning through hands-on practice on your own computer.

A UE5 Source Code Analysis Lecture by a top-level Unreal Engine expert.

This is an introductory course on creating multiplayer games in UE5. You will practice everything from theory to implementation of listen server-based multiplayer game development by recreating the actual game [Last Man Standing].

This lecture is for those who tried to study advanced algorithms but feel lost on how to approach problems with just the basic data structures and algorithms found in books.

In the era of agents, true skill comes from 'control.' You will perfectly master the operating principles of agents by building the core architectures of Claude Code—Agent, Tool, MCP, Skill, and AgentTeam—from scratch.

Even if you are new to Unreal Engine, taking this course will help you become familiar with it in just one day. It covers the basics thoroughly and only the necessary parts efficiently.

This course goes beyond simple grammar explanations and focuses on developing C++ programming skills that can be applied immediately in the field. Throughout my teaching, I have directly addressed common challenges faced by many learners—such as struggling to understand the STL or feeling confused by file handling and exception handling concepts. Based on this experience, I provide step-by-step explanations to ensure even complex concepts are understood easily and clearly. Furthermore, this course is not just about delivering theory; it is structured around: 👉 "Why this concept is necessary" 👉 "How it is used in actual code" 👉 "How it is applied in professional practice"

Easily learn data structures and algorithms, which were difficult to learn with C++, in easy steps. Unlike typical lectures, this course combines data structures and algorithms, allowing you to learn them simultaneously while considering their interrelationships.

🌿 Class Introduction This course focuses on learning Unreal Engine's Procedural Content Generation (PCG) system through a practical, hands-on approach. You will learn step-by-step techniques to automatically place complex terrain, roads, trees, and lighting, allowing you to build an efficient environment production pipeline without repetitive manual work. Rather than just listing nodes, we use a structural approach that can be applied immediately to projects to maximize production speed. 🚀 💡 3 Reasons Why This Class Is Special ❶ Practical PCG Approach We focus on **'project-centered design'** rather than just listing features. By linking core systems such as landscapes, splines, and level instances, you will build an automation pipeline and experience production efficiency at least three times faster than manual work. ⚡ ❷ Full Integration of PCG Graphs × Blueprints We create a structure where artists and programmers can work together by exposing PCG parameters to Blueprints. With a systematic PCG design that can control density, meshes, and even materials, you will secure powerful scalability even for large-scale projects. 🧩 ❸ Automation, Efficiency, and Scalability Implement everything from spline-based automatic placement of roads, streetlights, and fences to material and vegetation changes based on terrain slope. Complete real-world environment automation logic, such as automatically clearing forests around roads using 'Difference' and 'Distance' nodes. 🌲 Instructor Portfolio: twinvion.com
