In the official documentation there is an example on how to use this class. Part of the example contains this code:
# Wait until resolved and connected
while http.get_status() == HTTPClient.STATUS_CONNECTING or http.get_status() == HTTPClient.STATUS_RESOLVING:
However when I export such code to HTML5 and run it in a browser, I get the following error message in the Godot debugging console:
HTTPClient pooled multiple times in one frame, but request cannot progress more than once per frame on the HTML5 platform.
Further investigation allowed me to find that I should wait for frames instead of doing a delay, using this code:
But this is not always possible, especially when the script is in a utility class that isn't meant to be added in a scene, thus is an Object and not a Node.
What's the best strategy in such case?
I see that I can refactor my whole utility class to become a Node and add it to the scene just to have access to the SceneTree so I can wait for a frame, but it breaks the whole architecture and it makes dirty code, which I really want to avoid.
