Tamagotchi

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A tiny on-chain virtual pet. Hatch one, then keep it alive by feeding, playing, and letting it sleep — hunger, happiness, and energy all decay with block height, so neglect (or just forgetting to check in) eventually kills it. Hatching a new pet after a death keeps your lifetime feed/play/death counts, so the leaderboard rewards long-term care rather than a single lucky run.

Realm: gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/tamagotchi

Example calls

maketx call ... -func Hatch -args "Fluffy"     # start a pet
maketx call ... -func Feed                     # -30 hunger, +5 energy
maketx call ... -func Play                     # +20 happiness, -10 energy, +5 hunger
maketx call ... -func Sleep                    # +40 energy, +5 hunger

Render("") lists every pet ever hatched with alive/dead status and lifetime stats. Render("<owner-address>") shows one pet's detail card.

Toolchain status

gno test . passes (10/10 tests) against ~/p/gh/gnolang/gno as GNOROOT. Uses only chain/runtime, sort, strconv, and the kept gno.land/p/nt/avl/v0 / gno.land/p/nt/testutils/v0 packages per the sapphire stdlib reference. Panic paths are tested through non-crossing helper functions (hatch, feed, play, sleep) rather than through the exported cur realm entry points, since panics raised inside a realm-crossing call aren't recover()-able from the caller on this toolchain version.

What changed in v1

Identical behaviour to v0 apart from rendering, which now goes through p/moul/kit/ui instead of the local shortAddr helper.

One address format. Eleven realms carried their own shortAddr with four different truncation rules, so the same account rendered differently depending on which realm you opened. ui.Addr is that decision made once: 8 leading characters, an ellipsis, 4 trailing, in backticks.

The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. v0 stays live and untouched.
