Little Green Blob

A gameboy color platformer written in C using gbdk-2020.

Compiling

Modify GBDK_HOME variable in the Makefile with the path to the gbdk-2020 toolset

After that run Make -B. Output will be placed in build/gbc/main.gbc

Project structure

Most important functions should (hopefully in the future) have a descriptor comments on what their purpose is

src/main.c: Program code that resides in BANK 0.

src/banked/banked.c: Banked functions that couldn't fit in the primary memory bank.

src/banked/mapholder.c: a manager for retrieving pointers to map data & their corresponding memory banks.

src/maps/: all map (as in levels) source files

adding new maps

• The score saving system currently has enough room for total of 100 maps. Beyond that some modifications have to be made to the memory management of the save.

• See GBMB project files for reference or base for modifications: src/map_project_files/

• Export the new map with GBMB. Name your map uniquely, eg. Map20 (names Map00 to Map19 are already in use) Name the export files similarly to those in src/map_project_files/

• Run the converter described below to convert the exported source files to be compatible with the project

• Place the map source files into src/maps/

• Modify each function in src/banked/mapholder.c to include an entry for the new map. This is how the game loads the maps.

• Increment MAPCOUNT in src/main.c

• Compile the project. Now the new map should have an entry in the level selection menu.

converter

Contains a python script to convert gameboy map builder exports into versions compatible with this project.

Example call eg: python3 converter.py -sc map14.c -he map14.h

Outputs will be placed into equivalent files with .out suffix
