This is a mod for MCPI-Reborn that expands the "Expand Creative Inventory" mod even more, so that you have access to all items in the game.
To use this mod you will need to download the shared library and place it in the mods folder of minecraft: pi edition, to do this download libbci.so and run
wget https://github.com/MCPI-Revival/Expanded-Creative-Inventory/raw/main/libbci.so
sudo mv libbci.so /usr/lib/minecraft-pi-reborn-client/mods/libbci.so
Then all you need to do is run minecraft: pi edition with the "Expand Creative Inventory" feature activated. If you are using a launcher such as gMCPIl or jMCPIL, you'll want to enable it in the "Features" tab and launch with "Custom Profile" for the profile selection.
To compile your own version of it you will need to have gcc-arm-linux-gnueabihf
installed, and then clone this repo and run:
arm-linux-gnueabihf-g++ -shared -o libbci.so creative.cpp -DREBORN_HAS_COMPILED_CODE
This will compile a version of libbci.so with your changes. To use it just move it to /usr/lib/minecraft-pi-reborn-client/mods/
