I have a question to change vaule of omnigraph variable by python API.

I’m tring with bellow code. But it doesnt work ever without any errors.

 graph_path = "/World/ActionGraph"
            controller = og.Controller()
            keys = og.Controller.Keys
            
            graph = og.get_graph_by_path(graph_path)
            
            variable_name = node_name.replace("/", "_")
            read_node_name = variable_name+"_Reader"
            prim_name = graph_path + "/" + read_node_name
            
            controller.edit(graph_path, {
                keys.SET_VALUES: [
                    (f"{read_node_name}.inputs:value", new_value )
                ]
            })

So my question is like bellow:

  1. User couldnt change value of variable by python?

@gustjr31321 i am just another user, and i haven’t look too closely into the snippet you’ve provided. that said, have you tried referencing the omnigraph python scripting section from the official doc already along with omnigraph’s core API?

also, is the intent to use omnigraph for SDG or ROS2?
