From defdf202e6b2a9e3be6b587083865e0971dcf275 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?sijcdu=E7=9A=84=E6=B8=B8=E6=88=8F?= Date: Wed, 7 Oct 2026 22:38:07 +0800 Subject: [PATCH] Bullet field: pierce-through and damaging, rings spaced 3 cells apart Solid bullets were blocking the patrolling enemies, so the field now defaults to solid = false: each bullet is a plain StaticBody2D with no collision layer, plus an Area2D that only detects the player, so nothing is physically obstructed while contact still costs a heart. Ring radii changed from [5, 10, 15] to [3, 6, 9]. Damage is now applied every frame to whatever is overlapping, not only on body_entered, so standing inside a bullet keeps hurting instead of only the first touch. Also picks up the editor change that removed Walker_03. --- scenes/level2.tscn | 6 +---- scenes/main.tscn | 15 +++++-------- scripts/bullet_field.gd | 44 +++++++++++++++++++++++++------------ scripts/bullet_field.gd.uid | 1 + 4 files changed, 37 insertions(+), 29 deletions(-) create mode 100644 scripts/bullet_field.gd.uid diff --git a/scenes/level2.tscn b/scenes/level2.tscn index 3ab348a..2f77426 100644 --- a/scenes/level2.tscn +++ b/scenes/level2.tscn @@ -217,10 +217,6 @@ position = Vector2(216, 216) position = Vector2(306, 216) start_direction = 1 -[node name="Walker_03" parent="Level/PrefabInstances/Enemies" unique_id=1711052130 instance=ExtResource("18_walker")] -position = Vector2(90, 198) -start_direction = 1 -
