Is there a simple example that uses the EditorExportPlugin class? https://docs.godotengine.org/en/stable/classes/class_editorexportplugin.html#editorexportplugin
I was wondering if this class could be an easy way to store the export date/time somewhere, such as a project setting or file, that would be available at runtime.
After making the previous post, I found this, which may answer my question. I'll post later whether it did. https://docs.godotengine.org/en/stable/tutorials/plugins/editor/index.html#editor-plugins
I went through that tutorial, but got stuck on making an export plugin.
However, I found this example in the Assets library, which may help: https://godotengine.org/asset-library/asset/1173
I was able to use that example to create an export plugin that does what I want. It has some obscure stuff in it though, which doesn't seem to be in the official documentation.
