Headless Simulator
A lightweight runtime environment that renders no graphical interface and retains only core logic and state transitions, commonly used to accelerate the generation of training samples for reinforcement learning.
Timeline (last 90 days)
Training was done in a headless simulator the author wrote by hand in Rust, rather than running directly in the game itself.
A headless simulator refers to a lightweight runtime environment that does not render a graphical interface and retains only game logic and state transitions, which can generate training samples in high-speed batches and supports parallelization and time acceleration.
For closed-source commercial games like D2R, building one's own headless simulator can avoid the compliance risks brought by directly injecting into the game process.
A gap between the simulator and the real game is inevitable (monster AI, drop randomness, network latency, etc.), and the author did not elaborate on the simulation's accuracy.
The author used Claude to assist in building a headless simulator and calibrated it using parameters measured on a real phone.
The simulator has a C++ version that can complete 10 million steps of training in about 6 minutes, roughly 28,000 steps per second.
