@yagejs-tools/editor

Level editor for YAGE games. Place entities in a real running engine, drag them in the viewport, and save the result as a versioned level file that the game loads through @yagejs/level.

@yagejs-tools scope, independently versioned — an engine release never forces a bump here, and vice versa.

npm install -D @yagejs-tools/editor
npx yage-editor init       # write the config, the harness, the level project, the script
npm run editor             # start it
npx yage-editor validate   # check every level file against the project, for CI

Configuration, the harness, and what the editor can do today are documented at yage.dev/tooling/level-editor.
