From 39839dc5943c1b0cc71782b1fb25baae12afb204 Mon Sep 17 00:00:00 2001 From: Willem van den Ende Date: Mon, 15 Jun 2026 07:55:39 +0100 Subject: [PATCH] fix Allium specs syntax + implement Changing Level story MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix Allium spec syntax: type→value, enum for Status, remove implies chaining - Fix factions.spec: add missing type declarations (Health, Level, Status) - Fix magical-objects.spec: add type declarations, use .value for Health access, remove entity inheritance syntax, remove invalid invariants - Implement Changing Level: add totalDamageTaken + factionsJoined to Character - Add level-up logic in dealDamage() and joinFaction() - Add Level.damageThresholdForLevel() static method - Fix changing-level.spec.ts properties: handle target survival, compute expected level from threshold crossings --- .pi/specs/story-3-factions.allium | 26 ++++-- specs/magical-objects.allium | 141 +++++++++++++++--------------- src/changing-level.spec.ts | 49 ++++++----- src/characters/Character.ts | 52 ++++++++++- src/value-objects/Level.ts | 2 +- 5 files changed, 165 insertions(+), 105 deletions(-) diff --git a/.pi/specs/story-3-factions.allium b/.pi/specs/story-3-factions.allium index 6c4b0cd..00c770b 100644 --- a/.pi/specs/story-3-factions.allium +++ b/.pi/specs/story-3-factions.allium @@ -6,9 +6,22 @@ -- Value Types ------------------------------------------------------------ -type Faction { +value Faction { name: String -
