By calling [method rpc] with a method name, it will be called locally and in all connected peers (peers = clients and the server that accepts connections). To identify which node receives the RPC call, Godot will use its [NodePath] (make sure node names are the same on all peers). Also, take a look at the high-level networking tutorial and corresponding demos. </description> <tutorials> - <link>https://docs.godotengine.org/en/latest/getting_started/step_by_step/scenes_and_nodes.html</link> + <link title="Scenes and nodes">https://docs.godotengine.org/en/latest/getting_started/step_by_step/scenes_and_nodes.html</link> + <link title="All Demos">https://github.com/godotengine/godot-demo-projects/</link> </tutorials> <methods> <method name="_enter_tree" qualifiers="virtual"> @@ -129,11 +130,22 @@ Adds a child node.
