A lightweight, fast PID controller for Godot implemented as a C++ GDExtension.

Installation

If you wish to modify or recompile the addon, then you'll need to include the "godot-cpp" and "src" folders along with the "SConstruct" file from this repository.

If you want to compile your own binaries this is the best option. To put the addon in your project, just copy the "addons" folder into the project directory.

Tutorial

Just add a PIDController node to your scene, select a node/property to control, then begin tuning the gains. You can sellect whether the PIDController updates in the process or physics frame. If what you are trying to control is more complicated or you want finer control on when it updates, you can set the controller to update manually then call the update_state method directly. You can also add custom state integration for the controlled property by overriding the _integrate_state method in a script that extends PIDController. Both the PIDController node and the PID gains resource have built-in documentation for reference.

[!TIP] You can enable the PID controller in the editor if you want to use it for editor plugins or nodes that need to run in @tool mode.
