GraphEdit --- what kind of array does it have?

jana

I read the docs and learned that when you connect GraphNodes together, the GraphEdit keeps a list of the connections which can be accessed by

get_connection_list()

The documentation shows the array:

{ from_port: 0, from: "GraphNode name 0", to_port: 1, to: "GraphNode name 1" }

I don't know what kind of array this is. It doesn't seem to be a dictionary. I can't find any more info on what kind of array this is or how to access it's elements.

How does it work, or where it's documented?

It looks like it's an array of four-element structures as shown.

I looked for the .h and .cpp files for the class on github, but couldn't find them. Do you know how to locate those files?

I suppose I could download the github repository and grep for the class.

I found it: https://github.com/godotengine/godot/blob/master/scene/gui/graph_edit.h

The array contains elements like this:

struct Connection {
		StringName from;
		StringName to;
		int from_port;
		int to_port;
		float activity;
	};

The function's signature, from graph_edit.cpp:

void GraphEdit::get_connection_list(List<Connection> *r_connections) const {
	*r_connections = connections;
}

I'd have to experiment to see how to use that in GDScript.
