Using GDExtension
|
|
=================
|
|
|
|
**🛈 See also:** `What is GDExtension? <https://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/what_is_gdextension.html#what-is-gdextension>`_
|
|
|
|
LimboAI can be used as either a C++ module or as a GDExtension shared library.
|
|
The module version is the most feature-full and slightly more performant, but
|
|
it requires using custom engine builds including the export templates.
|
|
|
|
**🛈 Note:** Precompiled builds are available on the official
|
|
`LimboAI GitHub <https://github.com/limbonaut/limboai#getting-limboai>`_ page.
|
|
|
|
GDExtension version is more convenient to use, as you don't need a custom engine
|
|
build. You can simply download the extension and put it inside your project.
|
|
However, it has certain limitations, described in detail in the next section.
|
|
|
|
Whichever you choose to use, remember, your project will stay compatible with
|
|
both and you can transition from one to the other any time.

Limitations of the GDExtension version
|
|
--------------------------------------
|
|
|
|
GDExtension is the most convenient way of using the LimboAI plugin, but it comes
|
|
with certain limitations.
|
|
|
|
The biggest one is that marking methods as virtual for scripting is not
|
|
currently possible in godot-cpp. We use these methods to allow creating custom
|
|
behavior tree tasks in GDScript.
|
|
Due to a workaround we employ, the editor will complain about native
|
|
methods being overridden. And by default, such warnings are treated as errors.
|
|
You have two options...
|
|
|
|
In your Project Settings, you can edit ``Debug -> GDScript -> Warnings -> Native Methods Override``
|
|
and set it to either ``Warn`` or ``Ignore``.
|
|
Those settings are hidden, unless ``Advanced Settings`` toggle is switched on!
|
|
|
|
Alternatively, in your custom tasks, you can add specific instructions for
|
|
the parser to ignore the warning. For example:
|
|
|
|
.. code:: gdscript
|
|
|
|
# The following line instructs parser to ignore the warning:
|
|
@warning_ignore("native_method_override")
|
|
func _tick(p_delta: float) -> Status:
|
|
return SUCCESS
|
|
|
|
You would have to do that for each overridden method in your custom tasks.
|
|
It's up to you which option you prefer. Personally, I'd set it to ``Warn`` and
|
|
add ignores only if it gets overwhelming. Hopefully, this will be fixed in the
|
|
future releases of Godot!

**Other GDExtension limitations**
|
|
|
|
* Built-in documentation is not available. The plugin will open online documentation instead when requested.
|
|
* Documentation tooltips are not available.
|
|
* Handy :ref:`class_BBParam` property editor is not available in the extension due to dependencies on the engine classes that are not available in the Godot API.
