The Kokusai Collision Animation Editor comes from the old and now obsolete Kokusai Fighter Editor. It creates animations with collision boxes added to every frame. Very useful for fighting games, or for other games when sprites are too big or too complex to manage them with only one bounding box.
The Kokusai Script Editor creates simple scripts using my own scripting language. The user can create its own custom commands in separate modules, import them in the editor and use them in its own scripts.
The Kokusai FSM Editor creates finite state machines. It's designed to be used in conjunction with the Kokusai Script Editor, to create complex state machines with the flexibility of the scripts.
