VR-Forces Back-End Extension (displayStateData)

Table of Contents

• Retrieving State Data
• How to Run the Example
  • Usage
• Plugin Entry Points

The Display State Data example does the following

• How to install a new console command
• How to look up an object by name in the object manager
• How to retrieve state data from an object
• How to find and print out specific data from that state data

Retrieving State Data

This example shows how to create a VR-Forces Back End extension plugin and install your own console commands that can be issued to print out various data to the console associated with objects in the system. This example currently adds the following console commands:

• print-airbase <name> - prints airbase specific data. If the object is not an airbase a warning will be issued.
• start-movement-mission <name> - Starts a move to waypoint mission using F-16C aircraft at the supplied air base. If the object is not an airbase a warning will be issued.
• start-escort-mission <name> - Starts an escort mission using F-16C aircraft at the supplied air base. If the object is not an airbase a warning will be issued. You will need to add more F16 aircraft to the airbase in order to use this feature.
• print-status <name | ALL> - prints various status (health, fuel, equipment, weapon stores). If the object is not an airbase a warning will be issued. Use ALL to print out all aggregates.
• help-display - prints this list.

Since this example is loaded as a plugin, it can be used in conjunction with the released VR-Forces application.

How to Run the Example

This example demonstrates how to install your own derived object manager.

Usage

In the Launcher, click the Plug-ins button to bring up the Plug-ins Selection dialog. Enable the plugin.

To view the new behavior:

1. Launch VR-Forces GUI and SIM for HLA1516 Evolved only. This example, while it will build in multiple protocols, will only work in the 1516 Evolved protocol.
2. Load the userData\scenarios\developer_toolkit_examples\displayStateData\displayStateData.scnx in order to use this example.
3. The vrfSim console will print out information that the plugin is loaded and what commands are available.
4. If the list with the commands is not printed - type the help-display command in the VRF SIM console window. The available commands will be printed out.

5. Type a command from the list in the vrfSim console window and the corresponding state data will be printed out.

   print-airbase AB 1

6. To witness the movement-mission and escort-mission you will need to run at 15X—takes time for the base to launch the assets. Open the air base's information/FlightStatus tab to see this.

  Note: In Linux - you should not use the Launcher to start the SIM and the GUI. 
  You need to start the vrfSim and vrfGui, manually - from two separate terminal windows.
  The necessary front-end and back-end command line arguments can be copied from the Launcher UI.

   // When looking how to create a code task around a scripted task, you will need to know the scripted task script id you want to
   // create the code around, and then inspect that script in the VR-Forces GUI to determine which variables are in that task to determine what
   // reader writer variables need to be created and added to the scripted task.  For example, in the script below, the launch_flight_mission
   // scripted task is used.  If you look at the Launch Flight Mission script, you can see the variables in the code mentioned below.
   //
   // The important parts to notice are the Variable Name and Type.  The myVariableName is the reader/writer name you will use when creating your
   // scripted task variable.  The myType is the type of variable you will create.  There are some common types you can see in the scripted tasks:
   //
   // string - DtRwString
   // integer - DtRwInt
   // double - DtRwReal
   // simulationobject - DtRwObjectName
   // datetime - DtRwReal
   //
   // When creating these reader/writer variables to add to the scripted task, you need to create the variable with the appropriate name and assign the value you want.
   // For example, if you need to assign the AirBase, you would do:
   //
   // createFlightTask.setValue("Airbase", obj->uuid());
   //
   //
   // The code saying you are adding an Airbase variable to the scripted task, and, for printing out on the screen in a plan, the variable type it is (this part is optional).
   //
   // For something like a double you would do:
   //
   // createFlightTask.setDateTime("LaunchTime", 0.);
   //
   // And so on, for the variables you want to add to the scripted task.
