How We Upgraded Our Limn Engine Playground Editor to Support Version 4

说明与用途

更新了 Limn Engine Playground 编辑器以支持版本 4 (epic.js)。通过 DOM 遍历和字符串过滤实现了动态版本检测，允许引擎在无需后端的情况下进行切换。

问题

The Limn Engine Playground Editor did not support Version 4 (epic.js), preventing developers from accessing new features like built-in particle systems and audio management within the web-based editor.

结果

Implemented a lightweight, zero-dependency version switcher that connects UI dropdowns directly to core framework files. Developers can now select Version 4 in the editor and instantly see their game run with new features.

工作流

• Download the core engine script file named 'epic.js' and host it for accessibility.
• Update the scanner loop to include 'V4' in the text content check for version detection.
• Update the script routing conditionals to map 'v4' selections to the epic.js file URL.
• Test the version switcher to ensure the correct script is injected for Version 4.

证据

text.includes('V4')... 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.

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