RTG Crane Simulator

Training serious game · UE5 · quest system and instructor station

A training serious game for RTG crane operators, built in Unreal Engine 5 on a five-screen rig: a reusable quest system —task classes, task collections and events— drives the maneuvers, and a Pixel Streaming instructor station lets a trainer watch and intervene in the session remotely. I also built the block-based container generation system with encoding, the video optimization to sustain the stream, and migrated Pixel Streaming from Node.js to NestJS with a custom frontend.

The story

Problem

Training RTG crane operators on real equipment is expensive and risky, and instructors need to supervise and intervene in sessions without being inside the cabin.

Solution

I built an immersive Unreal Engine 5 simulator running on a five-screen station, with block-coded container generation, a reusable task system, and a remote instructor station via Pixel Streaming with NestJS signaling.

Result

Safe, repeatable training with real-time remote supervision, sustaining the stream thanks to the simulator's video optimization.

The systems I built in the engine

Unreal Engine Developer

Reusable Task System

I implemented a quest-like task system with task classes, task collections, and associated events, allowing reuse and flexibility in task creation.

Unreal Engine Developer

Floor Coding and Container Spawn System

I developed floor coding and a system for generating container blocks, optimizing the organization and management of loads in the simulator.
