Scenario State generation

Pulse Physiology Engine
1

So I used to be able to do the following in Unity to create my state but it seems like a lot of these methods are now gone? Any guidance on how to achieve the same?

public void GenerateEditorStateFromScenario()
        {

            Debug.Log("Using Pulse version " + PulseEngine.Version() + "-" + PulseEngine.Hash());

            string scenarioPath = AssetDatabase.GetAssetPath(initialScenarioFile);

            //The path for the data to create a state
            string pulseDataPath="";

            SEScenarioExec execOpts = new SEScenarioExec();

            var appDirectory = new DirectoryInfo(Application.dataPath);
            
            if (appDirectory.Exists)
            {
                var rootPath = appDirectory.Parent;
                pulseDataPath = $"{CourseHelper.Instance.GetCaffeinePackagePath()}3RD/PulsePhysiologyEngine/Data";
            }

            // Set the directory where Pulse can find its data files (usally bin/install)
            execOpts.SetDataRootDirectory(pulseDataPath);
            // Where do you want any states created by scenarios to go?
            execOpts.SetSerializationDirectory(Application.persistentDataPath + "/" +
                                    gameObject.name + "/states/");
            // Set empty CSV dir if you do not want a csv file
            execOpts.SetDataRequestCSVFilename("");
            //execOpts.SetDataRequestCSVFilename("");
            execOpts.SetLogFilename(Application.persistentDataPath + "/" +
                                    gameObject.name + "/scenarios/PulseScenarioRunner.log");
            execOpts.SetScenarioFilename(scenarioPath);

            //Modify the path to serialize
            JObject scenarioJSON = JObject.Parse(initialScenarioFile.text);
            string newStatePath = Application.dataPath + "/Pulse States/" + initialScenarioFile.name + "_state.json";
            scenarioJSON.SelectToken("..Filename").Replace(newStatePath);

            //Overwrite with new content
            File.WriteAllText(scenarioPath, scenarioJSON.ToString());            

            PulseUnityEngine pulse = new PulseUnityEngine();
            if (!pulse.ExecuteScenario(execOpts))
                Debug.Log("Error running scenario");

            AssetDatabase.Refresh();

            initialState = AssetDatabase.LoadAssetAtPath("Assets" + "/Pulse States/" + initialScenarioFile.name + "_state.json", typeof(TextAsset)) as TextAsset;

        }

I will need to get Unity up and running to look at this in detail

But have you looked at this HowTo?

That might be the answer, thank you. I’ll try to implement it with that new way.

Please, I started to use pulse engine in unity, and all i know to do is to run an existing scenario, and now i need to creat my own, can i have some guidance please, and thank you

We recommend using the Pulse Explorer to create and edit scenarios that create a state file that you can load into your Unity application

okey, thank you

Thank you again for your response, i have a second question, in my case, I want to simulate a COPD/pneumonia scenario in which I ask two questions to the participant.

The first question will be to ask them to identify the relevant clinical cues, in this initial state, I need to have specific vitals displayed on the monitor, I believe this would be my T0 state.

The second question will ask the participant to perform an action, and these actions should have an effect on the vital signs shown on the monitor.

So, my first question is: do I only need to use states, or do I need to use a full scenario?
And my second question, sorry for asking so much, is: what is the workflow to create a state file from an edited scenario?
In Pulse Explorer, it seems I only have the option to save a scenario, not a state.

Thank you again!
