Technical Guide: Building Cross-Platform Cloud Save Systems for Unity Games

·3 views

Game developers at ShortSingh outline a technical framework for building robust cloud save systems in Unity, addressing challenges that arise when games span multiple platforms and devices. The guide draws on real-world experience from projects including Domi Online, a persistent MMORPG, and RuneScape Mobile developed at Jagex. Key engineering problems covered include conflict resolution when two devices hold divergent saves, offline-first design for players with intermittent connectivity, and schema migration when game updates change save data formats. The recommended architecture separates save logic into three distinct layers — data model, local storage, and cloud sync — to keep each component independently testable and replaceable. Platform-specific considerations for Google Play Games Services, Apple Game Center, and Steam Cloud are also addressed, as each service carries its own failure modes and rate limits.

Dev Builds Theatre Prop Continuity Tracker to Catch Staging Errors

A developer created Prop Continuity Desk, a rehearsal planning web app designed to help small theatre productions track the physical movement of props across scenes. The app is built around a fictional six-scene play with twelve props and detects two key mistakes: placing the same prop in two locations within one scene, and moving a prop between scenes without a recorded transfer cue. It uses Next.js, React, TypeScript, and Sanity as its content backend, with scene reviews stored in separate documents to avoid overwriting the data being reviewed. A practice-copy feature lets visitors explore the rules without altering the live production plan, and any exported cue sheet from a practice session is clearly labelled as such. The project was built using Codex starting 26 September 2026, with the AI proposing the scenario, writing the code, and running the tests under the account owner's authorization.

Sekura JS Explores Sharing Software Verification Proofs Without Exposing Source Code

Sekura JS is developing an approach that separates a software module's source code from its verification contract (SJV) and proof artifact (SJP), allowing developers to share evidence of formal verification without disclosing proprietary implementations. The SJV document specifies the properties a module claims to satisfy, while the SJP carries the mathematical evidence produced during verification. A third-party verifier can replay the stored SMT obligations using tools like Z3 or CVC5 to confirm their validity without ever seeing the underlying source code. However, the project acknowledges a key limitation: replaying an SJP can confirm that the mathematical proofs are valid, but cannot independently verify that those proofs were actually generated from the specific private codebase the developer claims. This creates an explicit trust boundary between the private source code and the proof artifacts exchanged between parties.

Where Game Development Budgets Actually Go, Explained by Category

Game development costs are typically split across five core categories: engineering, art and audio, design, QA and testing, and project management. Engineering tends to consume the largest share, usually between 40 and 50 percent, covering gameplay systems, networking, platform work, and performance optimisation. Art and audio follow at 20 to 30 percent, while design, QA, and project management each account for roughly 5 to 15 percent. These ranges are based on agency-scoped projects and shift depending on genre, platform targets, team structure, and scope. When budgets are limited, understanding which category drives the most complexity for a given project can help teams prioritise spending more effectively.
