From 64aa6aef4003584d704833218fc877fa4c369b75 Mon Sep 17 00:00:00 2001 From: jedarden Date: Tue, 26 May 2026 18:39:12 -0400 Subject: [PATCH] test(web): add tests for combat_death attack arrow rendering MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Plan §5055: Attack event arrows from killers to victim position. Added 3 tests to verify: 1. Arrows are drawn from each killer to victim in combat_death events 2. Multiple arrows are drawn for multiple killers (2v1 situations) 3. Arrow colors are set based on attacker player color The tests mock the canvas context and verify that the appropriate drawing methods (moveTo, lineTo, stroke, fill) are called when rendering turns with combat_death events.
