Upgrading Limn Engine Playground Editor to Support Version 4

说明与用途

升级 Limn Engine Playground 编辑器以支持版本 4，使开发者能够动态加载新的 epic.js 脚本，获得新功能，而无需更改后端。

问题

The Limn Engine playground editor lacked support for the new Version 4 (epic.js), preventing developers from testing games with the latest features.

结果

The playground editor now dynamically routes to Version 4, enabling developers to test games with new particle systems and audio management without backend changes.

工作流

• 1. Download the core engine script epic.js from the official site and host it for injection.
• 2. Update the scanner loop to include a check for 'V4' when iterating over all <code>select</code> elements.
• 3. Add a conditional branch that sets <code>engineScriptFile</code> to the epic.js URL when the selected version contains 'v4'.
• 4. Test the editor by selecting V4 from the dropdown and verifying the game runs with new features.

证据

We added this check so that when the editor reads our UI elements, it officially registers Version 4 as a valid release option instead of skipping it.

来源

When a user selects v4 from the dropdown, this conditional matches the string and targets our newly hosted epic.js file for preview injection.
