VisualScript module for Godot

This repository contains the implementation of the "VisualScript" visual scripting language which used to be included directly in Godot Engine from Godot 3.0 until its removal in Godot 4.0.

See this blog post for details on why the VisualScript implementation was removed from Godot 4.0.

This repository has two aims:

• Initially, this is a straight copy of the modules/visual_script/ folder in the Godot source tree, and can still be compiled as such to restore this functionality in Godot 4.0.
• Ideally, if there is community interest and participation, we would like this module (which needs to be compiled together with the engine in a custom build) converted to use GDExtension via godot-cpp, allowing it to be distributed as a compiled library that can add this functionality back to a stock Godot build. As an extension, this feature could also evolved more freely, attracting new contributors with innovative ideas, and thus become a better visual scripting solution than what we had in the Godot 3.x era.

Compiling

For now this is still a C++ module, so it needs to be compiled together with Godot as a custom build.

See the Godot documentation for instructions on how to compile the engine.

To add this module, it should be cloned or copied as the modules/visual_script/ folder in the Godot source tree.

For example:

git clone https://github.com/godotengine/godot
cd godot/modules
git clone https://github.com/godotengine/godot-visual-script visual_script
cd ..
scons

Note that a custom visual_script name is given for this repository's clone, so that the final structure looks like modules/visual_script/ and not modules/godot-visual-script/.
