Crate nimble_assent 

nimble-assent is a library designed for deterministic simulation of game logic based on player input. It operates on the concept of “steps” (or actions) taken by players and ensures these steps are applied in a specific, predictable order. This library integrates smoothly with deterministic simulations, ensuring that all participants in a networked game that receive and process the same steps in the same order, yield identical results.

Why “Assent”?

The name “Assent” was chosen because it reflects the concept of agreement or concurrence. In a deterministic simulation, especially for multiplayer games, it is crucial that all parties (the players and the host) are in complete agreement on the sequence of steps or actions taken. In this context, “assent” represents the system’s role in enforcing an authoritative and agreed-upon sequence of events, ensuring that everyone shares the same view of the game state at every step.

Overview

The main structure in this crate is the Assent struct, which handles the simulation of player input (called “steps”) over a series of game ticks. The crate is designed to:

• Queue player inputs (steps) with associated tick IDs.
• Apply these inputs consistently across all participants in the simulation.
• Limit the number of ticks processed per update to avoid overloading the system.

The crate also provides a customizable callback mechanism (AssentCallback) that allows developers to hook into different stages of the update cycle, enabling detailed control over how steps are processed.
