From 372ea3d58680ab2da45661f5f96ed280c4982e9c Mon Sep 17 00:00:00 2001 From: Thomas Date: Sun, 1 Mar 2026 16:48:53 +0000 Subject: [PATCH] Upgrade level editor for moon campaign support Preserve tileset path and parallax style on save instead of hardcoding tileset.png. Add tileset cycling (T key), tile flag editing (F key for solid/platform/hazard/none), and 8x8 pixel mini-icons for all entity types in the palette and canvas. Fix entity palette not appearing when editor starts without a prior level load by splitting entity_registry_init into populate and init phases. Fix bitmap font rendering dropping the top row by correcting FONT_H from 6 to 7. Widen toolbar button spacing. Fix invisible collision from placed tiles lacking TileDefs by calling ensure_tile_def on pencil and fill placement. Fix editor hotkeys not working in the web build by latching key presses from SDL_KEYDOWN events instead of comparing keyboard state snapshots. --- assets/levels/moon01.lvl | 71 +++++----- src/engine/input.c | 27 ++-- src/engine/tilemap.c | 1 + src/engine/tilemap.h | 1 + src/game/editor.c | 280 ++++++++++++++++++++++++++++++++++--- src/game/entity_registry.c | 69 +++++---- src/game/entity_registry.h | 28 ++++ src/game/level.c | 4 +- 8 files changed, 382 insertions(+), 99 deletions(-) diff --git a/assets/levels/moon01.lvl b/assets/levels/moon01.lvl index 405d42a..b73df33 100644 --- a/assets/levels/moon01.lvl +++ b/assets/levels/moon01.lvl @@ -1,42 +1,40 @@ -# Moon Surface - Landing -# ====================== -# Extended moon level: wide chasms with floating platforms. -# Pure jump-and-run intro with asteroid hazards.
