SignalVisualizer displays the current scene and autoload signal connections in an easy to read graph and tree dock.  ## YouTube ### Visualization [](https://www.youtube.com/watch?v=eCWlVX9pwGU) ## Installation The SignalVisualizer plugin can be installed from source or the Godot Asset Library. ### Godot Asset Library Installation 1. In Godot's AssetLib tab, search for SignalVisualizer 1. Download & Install [Godot Asset Library: SignalVisualizer](https://godotengine.org/asset-library/asset/2067) ### Installation via GitHub 1. Download the repo 2. Copy the `addons/SignalVisualizer` directory to your project's `res://addons/` directory. 3. Enable the plugin under Project Settings -> Plugins  4. The `Signal Visualizer` tab will display in the bottom dock region.  5. The `Signal Debugger` tab will display as a new panel in the Debugger dock.  ## Usage

Signal Visualizer

Signal Visualizer will create a signal graph by mapping the persisted signal connections in the current scene and project autoloads in the Godot editor. The bottom dock uses the built-in `GraphEdit` and `Tree` nodes to display the signal graph. Only signals with the flag of `CONNECT_PERSIST` will be displayed in the signal graph. In addition, all nodes that begin with `@` in the name will be ignored. 1. With your scene open in the editor, open the bottom dock. 2. In Signal Visualizer's top toolbar, click "Generate Graph"  #### Arrange Nodes Toggle The "Arrange Nodes" toggle enables and disables automatic node arrangement when generating the graph. When enabled, `GraphEdit`'s `arrange_nodes()` function will be called once all graph nodes are generated. #### Opening Signals in Source The "Open" button that displays next to a signal's connected function will open the corresponding source file at the function's line number. #### Format In the signal graph and tree, the format is as follows: ##### Outgoing Signal ``` Signal -> Connected Node ```  ##### Incoming Signal ``` Signal::Callable Method ``` 

Signal Debugger

The Signal Debugger connects to a running scene instance to allow for automatic logging of live signal executions. This includes signals connected through code at runtime and alleviates the need to add `print` statements to your own code when debugging signals. The Signal Debugger panel has two main components. The first is the signal tree. Similar to Signal Visualizer, all relevant scene and autoload signals are displayed in the tree.  The second main component is the signal log output. This is the main body of the Signal Debugger panel and contains all log messages for signals that have been triggered in the scene.  With your game scene running, navigate to the Signal Debugger panel under the Debugger dock item. Click the `Start` button to begin signal logging. With the Signal Debugger started, the scene's signal tree will appear and a started message will appear in the signal log output. All relevant signals will log the following: * Timestamp * Node that fired the signal * Signal Name  Clicking `Stop` will stop signal debugging, disconnecting from all relevant signals in the current game scene. Closing the current game scene will disconnect and stop debugging as well.
