From acc7901c2acad5a745af0b91425a49cb50999022 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 22:51:56 +0800 Subject: [PATCH] Add level 3: bullet rain from the sky, and ropes that only block bullets The tileset gained a second physics layer (collision_layer 2) and the rope tile (11,4) now carries its 18x6 polygon on that layer instead of layer 0, so it is invisible to anything that does not ask for layer 2. The player's mask stays 1 and the key copies it, so both fall straight through ropes; the bullet probe mask went from 1 to 3 so falling bullets are stopped by them. New bullet_rain prefab drops bullets at random x across the level on a jittered timer, sparse by default (1.0s +- 0.6s), and level 3 places one spanning the whole width. Level 3 has no lasers, and level 2's clear screen now leads into it. --- .../game/tilesets/kenney_terrain_tileset.tres | 2 + scenes/level2.tscn | 1 + scenes/level3.tscn | 255 ++++++++++++++++++
