From 78b7d38359dc66b67e76f74047ce7f9e3040dfa4 Mon Sep 17 00:00:00 2001 From: scawful Date: Fri, 10 Oct 2025 02:40:59 -0400 Subject: [PATCH] feat: Implement Downwards Drawing Routines in ObjectDrawer - Added multiple downwards drawing routines for various object types, enhancing the rendering capabilities of the ObjectDrawer. - Implemented methods for drawing 2x2 and 4x2 tiles with specific patterns and sizes, including edge cases for certain object IDs. - Updated the initialization logic to map new object IDs to their respective drawing routines, ensuring comprehensive coverage for downwards rendering. - Introduced debug logging for object drawing to facilitate troubleshooting and performance monitoring. --- src/app/zelda3/dungeon/object_drawer.cc | 225 ++++++++++++++++++++++++ src/app/zelda3/dungeon/object_drawer.h | 20 +++ src/app/zelda3/dungeon/room.cc | 7 +- 3 files changed, 251 insertions(+), 1 deletion(-) diff --git a/src/app/zelda3/dungeon/object_drawer.cc b/src/app/zelda3/dungeon/object_drawer.cc index 1fdd4702..eafab058 100644 --- a/src/app/zelda3/dungeon/object_drawer.cc +++ b/src/app/zelda3/dungeon/object_drawer.cc @@ -18,6 +18,9 @@ absl::Status ObjectDrawer::DrawObject(const RoomObject& object, gfx::BackgroundBuffer& bg1, gfx::BackgroundBuffer& bg2, const gfx::PaletteGroup& palette_group) { + LOG_DEBUG("ObjectDrawer", "Drawing object 0x%02X at (%d,%d) size=%d", + object.id_, object.x_, object.y_, object.size_);
