It provides basic\n    entity selection, positioning with mouse dragging, and basic camera\n    control. It has two variants behind feature flags - `vpeol_2d` and\n    `vpeol_3d`.\n* A knobs mechanism for more visual editing.\n* Playtest the levels inside the editor.\n* Multiple entity selection in the editor with the Shift key.\n\n## Examples:\n\n* WASM examples - you can't save the levels because it's WASM, but you can edit the levels run playtests:\n  * 2D editor: https://idanarye.github.io/bevy-yoleck/demos/example2d\n\n    https://user-images.githubusercontent.com/1149255/228007948-31a37b3f-7bd3-4a36-a3bc-4617d359c7c2.mp4\n  * 3D editor: https://idanarye.github.io/bevy-yoleck/demos/example3d\n\n    https://user-images.githubusercontent.com/1149255/228008014-825ef02e-2edc-49f5-a15c-1fa6044f84de.mp4\n\n  * Loading multiple levels and unloading them on the fly: https://idanarye.github.io/bevy-yoleck/demos/doors_to_other_levels\n\n    https://github.com/idanarye/bevy-yoleck/assets/1149255/590beba4-2ca5-4218-af52-143321bb5946\n\n    The WASM version of this example is gameplay only. To see how the editor for it looks like, clone/download the repository and run:\n    ```rust\n    cargo run --example doors_to_other_levels --features vpeol_2d,bevy/png\n    ```\n* Example game:\n  * Download binaries from https://aeon-felis.itch.io/danger-doofus\n  * See the code at https://github.com/idanarye/sidekick-jam-entry-danger-doofus\n  * Run the exeutable with `--editor` to edit the game levels with Yoleck.\n\n## File Format\n\nYoleck saves the levels in JSON files that have the `.yol` extension. A `.yol`\nfile's top level is a tuple (actually JSON array) of three values:\n\n* File metadata - e.g. Yoleck version.\n* Level data (placeholder - currently an empty object)\n* List of entities.\n\nEach entity is a tuple of two values:\n\n* Entity metadata - e.g. its type.\n* Entity componments - that's the user defined structs.\n\nThe reason tuples are used instead of objects is to ensure ordering - to\nguarantee the metadata can be read before the data. This is important because\nthe metadata is needed to parse the data.\n\nYoleck generates another JSON file in the same directory as the `.yol` files\ncalled `index.yoli`. The purpose of this file is to let the game know what\nlevel are available to it (in WASM, for example, the asset server cannot look\nat a directory's contents). The index file contains a tuple of two values:\n\n* Index metadata - e.g. Yoleck version.\n* List of objects, each contain a path to a level file relative to the index\n  file.\n\n## Versions\n\n| bevy | bevy-yoleck | bevy_egui |\n|------|-------------|-----------|\n| 0.15 | 0.25        | 0.33      |\n| 0.15 | 0.24        | 0.32      |\n| 0.15 | 0.23        | 0.31      |\n| 0.14 | 0.22        | 0.28      |\n| 0.13 | 0.21        | 0.27      |\n| 0.13 | 0.20        | 0.26      |\n| 0.13 | 0.19        | 0.25      |\n| 0.12 | 0.18        | 0.24      |\n| 0.12 | 0.16, 0.17  | 0.23      |\n| 0.11 | 0.15        | 0.22      |\n| 0.11 | 0.13 - 0.14 | 0.21      |\n| 0.10 | 0.7 - 0.12  | 0.20      |\n| 0.9  | 0.5, 0.6    | 0.19      |\n| 0.9  | 0.4         | 0.17      |\n| 0.8  | 0.3         | 0.15      |\n| 0.7  | 0.1, 0.2    | 0.14      |\n\n## License\n\nLicensed under either of\n\n * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0)\n * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT)\n\nat your option.\n\n### Contribution\n\nUnless you explicitly state otherwise, any contribution intentionally submitted\nfor inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any\nadditional terms or conditions.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fidanarye%2Fbevy-yoleck","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fidanarye%2Fbevy-yoleck","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fidanarye%2Fbevy-yoleck/lists"}
