From 3dac1b13d77ef01adf61b0f8e409fd78bf6e7aa7 Mon Sep 17 00:00:00 2001 From: Linus Probert Date: Mon, 6 Oct 2025 14:58:40 +0200 Subject: [PATCH 1/2] New minimap The minimap will now correctly render rooms according to shape and layout. Walls, pits, traps, doors and level exit are represented. Next step is to allow for a larger view of the map to be togglable. --- CMakeLists.txt | 2 +- src/gui.c | 116 +++++++++++++++++++++++++++++++++++++------------ src/gui.h | 28 +++++++++++- src/input.c | 1 - src/main.c | 16 +++++-- src/map.c | 17 +++++--- src/map.h | 35 ++++++++------- src/player.c | 1 + src/skill.c | 1 + 9 files changed, 161 insertions(+), 56 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index faf30d66..086ac27b 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -213,7 +213,7 @@ set(INCLUDE_DIRS add_executable(${PROJECT_NAME}) add_subdirectory(src) add_subdirectory(lib/sqlite3) -set_property(TARGET ${PROJECT_NAME} PROPERTY C_STANDARD 99) +set_property(TARGET ${PROJECT_NAME} PROPERTY C_STANDARD 11) target_include_directories(${PROJECT_NAME} PRIVATE ${INCLUDE_DIRS}) if (NOT MSVC) diff --git a/src/gui.c b/src/gui.c index f324ff1d..79155185 100644 --- a/src/gui.c +++ b/src/gui.c @@ -23,6 +23,12 @@ #include #include "gui.h" +#include "SDL3/SDL_blendmode.h" +#include "SDL3/SDL_pixels.h" +#include "SDL3/SDL_render.h" +#include "defines.h" +#include "roommatrix.h" +#include "texture.h" #include "util.h" #include "map.h" #include "texturecache.h" @@ -186,10 +192,22 @@ init_sprites(Gui *gui, Camera *cam) BOTTOM_GUI_HEIGHT/16, cam);
