SimVar

This Node can be used to retrieve a SimVar (Simulation Variables) value. The output value will depend on the options you set up in the Inspector window:

The available options are:

 

• SimVar

  Selecting this will open a drop-down list of all the different SimVars available to you.
  IMPORTANT! Only the following SimVars are currently implemented correctly:
  
  SIMVAR_STRUCT_LATLONALT
  SIMVAR_STRUCT_LATLONALTPBH
  SIMVAR_STRUCT_PBH32
  SIMVAR_STRUCT_WORLDVELOCITY
  SIMVAR_STRUCT_WORLD_ROTATION_VELOCITY
  SIMVAR_STRUCT_BODY_VELOCITY
  SIMVAR_STRUCT_BODY_ROTATION_VELOCITY
  SIMVAR_STRUCT_BODY_ROTATION_ACCELERATION
  SIMVAR_STRUCT_SURFACE_RELATIVE_VELOCITY
  
  Other sim vars can still be used, and the majority will return a floating point (scalar) value. If the value being returned should be a boolean value, then 0.0 is considered "false" and anything greater than 0.0 would be "true".

 

• SimVarIndex

  Here you can select the SimVar index value. Not all SimVars require this value, but it is needed for things like engines, where you need an index to indicate which engine you want to retrieve a value from.

 

• Unit

  This is for setting the unit type of the SimVar being retrieved. It can be any one of those listed here: Simulation Variable Units

 

 

Node Output

The output of the node will very much depend on the SimVar that is being used to generate it, however currently the supported SimVars will only return a 3 value vector.
