An example of using shader parameters to fade strokes in and out ### DrawAndAnimateStrokes An example of drawing procedurally on startup and then using shader parameters to animate the strokes it has created ### Lines An example of drawing continuously. It draws random straight lines for as long as the script is active. ### RandomPanorama Randomly downloads a panorama from Openverse and sets it as the current skybox. Not every skybox is valid so you might need to toggle the script a few times. Also - they are quite large files. If you're short of space - make sure you have a clear out occasionally! --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.openbrush.app/user-guide/using-plugins/example-plugins/example-background-plugins.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
