Hey there, I'm the author of tic80-typescript, so I can provide some pointers for you and other interested developers.
tic80-typescript is indeed not compatible with TIC-80 0.90.x due to API changes, sorry about that. Though it is compatible with TIC-80 1.0.x-dev (pro), if you're willing to build it yourself.
The tool itself simply streamlines the usage of typescript for TIC-80:
- It setups a typescript project with a .d.ts file for the TIC-80 API (yay autocompletion), and a basic tsconfig.json.
- It compiles your project into a single .js file that is compatible with Duktape, the js engine used by TIC-80.
- It does not support modules or npm dependencies; those are usually managed by the environment (like Node) or more advanced bundlers (like Webpack)
- On top of that, it automatically starts TIC-80, injects the compiled code into the game, and watches code changes.
If you have any question or issue, feel free to ask here or on the GitHub repository.
