SEPARATE / FOR DEVELOPERS
The source archive is separate from the ready-to-run installer. It contains application code, tests, public documentation and Windows build definitions.
It excludes development environments, private project paths and profiles, game data, accounts, saves, test output and release binaries.
Download source ZIP ↗Use x64 Python with Tk support, install the listed requirements in your own virtual environment and run desktop_app.py. The included source README explains the checks and optional Windows installer build.
Third-party dependencies retain their own licenses and notices. The source download is for people who want to inspect or build the application; most users should choose the installer above.
RELEASE DETAILS
Read the full update history →
Version 0.31 adds reusable script recipes, code previews, Classic UO rock faces, terrain review, native cave mouths and ethereal-style item mounts. The current guide covers these workflows.
The development unittest suite passed 471 tests. Read-only terrain checks cover all six standard facets, native UOP chunk boundaries, both Britannia sizes and trailing padding. Region checks cover boundaries, rules, encoding, reviewed add/remove, stale-file protection, queues and backup restoration. Source GUI/runtime checks pass; packaged executable launch remains unverified. RunUO and ServUO each passed compilation of 61 generated examples against official sources. ModernUO passed 61 syntax checks and source comparisons; a full native build remains required. This release checks three native sample exports and a full Britannia-sized terrain review. Connected-player Sphere checks cover item mounting, dismounting, repeated clicks, denied mounts and paired-item cleanup. Custom shard hooks, death and restart require target-shard testing. These checks do not replace connected gameplay testing. Screenshots and animations on these pages use controlled demonstration data in the actual app.
No. The visual scene is inside Studio and reads the linked artwork. It does not simulate Sphere gameplay or replace final in-game testing.
No. Bring your own compatible client data and, for script workflows, your own Sphere scripts. The website examples show demonstration projects.
Yes. Close Studio and run the new installer. Its stable application identity and previous-install detection are designed to update the existing installation.
No. World generation exports a new folder. Deployment, matching client/server map dimensions, patches, regions and spawns remain deliberate separate steps.
Choose Sphere X, official RunUO 2.x, ServUO pub57 or the ModernUO preview when generating a new script. ModernUO still needs full native compilation and shard testing. Expansion rules, combat configuration, custom events and loot rules determine the final behaviour. The existing source editor remains Sphere-specific.
