On the collision processing code (Chapter 6 - Jumping and squashing monsters) there is a misleading comment saying that the collision.get_collider() == null has the purpose of checking for a collision with the ground.
This addresses the following open issue: https://github.com/godotengine/godot-docs/issues/9355
This allows users to leave comments on pages that don't have
`:allow_comments: False` somewhere in the page's source.
Both manual and class reference pages can receive comments.
Index pages cannot have comments, as discussion should occur on "leaf" pages.
GitHub Discussions is used as a backend on the same repository. This means
that Discussions *must* be enabled on godotengine/godot-docs before this
commit is merged to `master`. Users can choose to use the "Custom" watch
mode if they don't want to get notifications for discussion updates,
but still get notifications for issue and pull request updates.
User comments are intended to be used for the following purposes:
- Add a clarification or correct something in the documentation,
without having to open a pull request. Contributors are encouraged to
take a look at discussions from time to time, and see if there's information
worth incorporating in the pages themselves. Don't forget to reply to
the comment when doing so :)
- Mention a workaround for a common issue.
- Link to useful third-party resources that are relevant to the current page,
such as tutorials or add-ons.
User comments should *not* be used for technical support. Other community
platforms should be used for that.
Page-to-discussion matching is done using the `pagename` Sphinx variable,
which is independent of the Godot version and documentation language.
Being independent of the Godot version allows keeping old comments
when the Godot version changes, while also allowing users from `/stable`
and `/4.1` to "see" each other in discussions.
See https://giscus.app for more information.
The order of mentioned nodes (SpawnPath and SpawnLocation) does not match the previous sentence when using "respectively". The following image confirms the order may be backwards.
This reduces the size of ZIP downloads for offline reading.
Unused images were found by running `_tools/list-unused-images.sh`.
These images were used in Godot 2.x and 3.x documentation,
but have been replaced by remade images with different names since.
Some of these images were duplicates or not relevant anymore,
so they have been removed entirely. Others have had their links fixed
or added where relevant.
