C Starter Project Template

Pre-requisites

• WASI SDK

Files in this template

• buildcart.sh - convenience script to build and run the game cartridge
• buildwasm.sh - convenience script to build and run the Wasm program
• Makefile - convenience Makefile that builds the project
• wasmdemo.wasmp - TIC-80 Wasm 'script' file. Note the embedded game assets data at the end of the file.

Building your game

Define the environment variable WASI_SDK_PATH; e.g., if you installed WASI into $HOME/wasi-sdk, then export WASI_SDK_PATH=$HOME/wasi-sdk.

Edit src/main.c to implement your game. You are of course free to organize your code in more than one C source file.

If you create sprites, map, music, etc., for your game, remember to replace the game asset data at the end of wasmdemo.wasmp with your creations.

To build the Wasm file, execute make. This generates cart.wasm in the build directory. To run:

% tic80 --fs . --cmd 'load wasmdemo.wasmp & import binary cart.wasm & run & exit'

The script buildwasm.sh contains above steps as a convenience.

To build a TIC-80 cartridge, first build the Wasm file, then build the cartridge file:

% tic80 --fs . --cmd 'load wasmdemo.wasmp & import binary cart.wasm & save game.tic & exit'

You can then run your cartridge as follows:

% tic80 --fs . --cmd 'load game.tic & run & exit'

The script buildcart.sh does the above steps as a convenience.

Additional Notes

TIC-80 API functions that merely duplicate standard library functionality are not imported. Please use the memcpy and memset functions provided by the C standard library instead.
