Work in progress! Code will most likely not stabilize before 2023 2024 2025, if I even get it to a stable state at all.

The ambition is to make a shoot 'em up maker with the ability for users to create their own shoot 'em up stages.

You can try version 0.7.1 here: https://fredrik-hjarner.github.io/schmupinator/

You can try version 0.6.0 here: https://fredrik-hjarner.github.io/schmupinator-0.6.0/

You can try version 0.5.0 here: https://fredrik-hjarner.github.io/schmupinator-0.5.0/

Teasers

Current state

• You can play 4 simple games
  • vertical shmup
  • horizontal shmup
  • asteroids
  • snake
• Highscore, separate for each level, that saves in localStorage.
• You can theoretically build your own stages and enemies with JS/TS files, but really, you will need a tutorial or be pretty smart (200 IQ 150 IQ) to figure out how to do it.

Preliminary goals for the game/maker

1. Make it able to do everything that the game Truxton can do. Truxton is an old shoot 'em up game that is relatively primitive so is easy to mimic.
2. Make it not too hard to create enemies and stages. A good tutorial and documentation is needed.
3. A dream goal is to create a stage and enemy editor, but in order for that to be feasible the code must first have stabilized.
4. Server that stores highscores and custom stages.

Preliminary goals for the code

• Robust code that never breaks.
  • Every file edit starts a test that runs a stage (with pre-recorded inputs) from start to finish to assert that behavior is exactly as expected.
• As few dependencies as possible. Fewer dependencies can increase the life span of a project since it will not rely on 1 000 dependences that can will break.
  • The code currently has zero runtime dependencies.
• No canvas or OpenGL. Every enemy, bullet, etc. is a div!

How to clone, build and run Schmupinator locally?

1. Install the requirements if you don't have them.
   • Install node (usually lastest version, but use version 18 if you have problems).
   • Install git (optional).
2. Download repository.
   • Alt 1 - with git
     • Create a directory for Schmupinator. Open the created directory in a terminal.
     • Clone repository by running git clone https://github.com/fredrik-hjarner/schmupinator.git . in terminal.
   • Alt 2 - without git
     • If you dont want to use git, then download zip-file here. Extract and open terminal in the extracted directory.
3. Run npm install in terminal.
4. Run npm run dev in terminal.
   • This should open http://localhost:3000/ in a web browser, if not then open it manually.
