From 72f632556ef0d1edb9b06623e20939737ca50b89 Mon Sep 17 00:00:00 2001 From: Sorra the Orc <> Date: Fri, 19 Jun 2026 11:15:42 +0100 Subject: [PATCH 01/19] CG-0MQK0SKBA005QZFR: Fix patron disappearing before animation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Patron was being removed from the patron column display before its fly animation started. This happened because executeTurn() removes the patron from session.patrons and adds it to player.patrons, then onRefreshAll() rebuilds the patron display from the (now empty) patron list — but the fly animation hadn't started yet. Fix: Add a patron animation cache to FeudalismRenderer that keeps the patron visible in the patron column during card purchase/reserve animation. The cache is set before the initial refresh, and cleared after the patron fly animation completes (onRefreshPatronsAndPlayer), at which point the patron is properly shown in the player area. Changes: - FeudalismRenderer: Added patronAnimationCache field and cachePatronForAnimation() method. refreshPatrons() renders cached patron alongside session patrons. - FeudalismTurnController: Added onSetPatronAnimationCache callback. Set cache before initial refresh in executeAction/executeAiTurn, clear after patron fly completes (onRefreshPatronsAndPlayer). - FeudalismScene: Wired onSetPatronAnimationCache to renderer method. --- .../feudalism/scenes/FeudalismRenderer.ts | 85 ++++++++++++------- .../feudalism/scenes/FeudalismScene.ts | 1 + .../scenes/FeudalismTurnController.ts | 28 +++++- 3 files changed, 79 insertions(+), 35 deletions(-) diff --git a/example-games/feudalism/scenes/FeudalismRenderer.ts b/example-games/feudalism/scenes/FeudalismRenderer.ts index 3df0eeea..eed1a973 100644 --- a/example-games/feudalism/scenes/FeudalismRenderer.ts +++ b/example-games/feudalism/scenes/FeudalismRenderer.ts @@ -2,7 +2,7 @@ * FeudalismRenderer — UI creation and refresh logic for Feudalism. */ import Phaser from 'phaser'; -import type { ResourceType, ResourceOrWild, DevelopmentCard, Tier } from '../FeudalismCards'; +import type { ResourceType, ResourceOrWild, DevelopmentCard, PatronTile, Tier } from '../FeudalismCards'; import { RESOURCE_TYPES, tokenCount, @@ -88,6 +88,10 @@ export class FeudalismRenderer { discardSelection: Partial> = {}; discardNeeded = 0; + // Patron animation cache: keep a patron visible in the patron column + // during card-purchase/reserve animation before its own fly animation starts. + private patronAnimationCache: { tile: PatronTile; index: number } | null = null; + constructor(scene: Phaser.Scene, session: FeudalismSession) { this.scene = scene; this.session = session; @@ -96,6 +100,11 @@ export class FeudalismRenderer { // ── Getters ───────────────────────────────────────────── get instruction(): Phaser.GameObjects.Text { return this.instructionText; } get selectedCardId(): number | null { return this.selectedMarketCardId; } + + /** Cache a patron that should remain visible during animation. */ + cachePatronForAnimation(patron: PatronTile | null, index: number): void { + this.patronAnimationCache = patron ?

charset=UTF-8 Content-Transfer-Encoding: 8bit Bug: When the Golf discard pile has exactly one card and the player draws it, the discard pile sprite continued to show the drawn card's face instead of updating to an empty-pile ghosted card-back placeholder. Root cause: GolfAnimator.updateDiscardPileAfterDraw() called the deprecated no-op showDiscardPlaceholder() for the size <= 1 case, so no visual update occurred. Fix: Replace the no-op with direct sprite manipulation that sets the discard sprite to the ghosted card-back texture ('card_back' at alpha 0.25, matching PileView's emptyAlpha configuration). Direct manipulation is required here rather than calling PileView.update() because the card has only been peeked from the pile at this stage — popOrThrow() happens later in executeTurn(). Test: Enhanced the existing 'Draw from discard pile' browser test to verify that after drawing the only discard-pile card, the discard sprite texture is 'card_back' with ghosted alpha, while the model still correctly reports 1 card (since the pop happens on the subsequent move). --- example-games/golf/scenes/GolfAnimator.ts | 8 ++++++- tests/golf/GolfInteraction.browser.test.ts | 25 ++++++++++++---------- 2 files changed, 21 insertions(+), 12 deletions(-) diff --git a/example-games/golf/scenes/GolfAnimator.ts b/example-games/golf/scenes/GolfAnimator.ts index 3e7b1eb6..d3ea58d4 100644 --- a/example-games/golf/scenes/GolfAnimator.ts +++ b/example-games/golf/scenes/GolfAnimator.ts @@ -237,7 +237,13 @@ export class GolfAnimator { updateDiscardPileAfterDraw(): void { const pile = this.session.shared.discardPile; if (pile.size() <= 1) { - this.renderer.showDiscardPlaceholder(); + // Pile will be empty after the draw — show the ghosted card-back + // placeholder.

The correct compact textures (e.g., lc-blue-2-sm) were already prewarmed by prewarmTextures(), but the lookup used the wrong template ID and a non-fallback-aware function.

Changes: - Added OverlayRect interface (headless-compatible, no Phaser import) - Extended ResumeOverlayScene.add with rectangle() method - Added BACKGROUND_DEPTH constant (2000, below TEXT_DEPTH 2001) - Background created at center, full-screen (1280x720), interactive to block pointer events - Background destroyed on both Resume and New Game dismissal - Added comprehensive unit tests (17 tests) covering background creation, input blocking, destruction, hover effects, and callbacks Acceptance criteria: all 7 criteria satisfied.
