Question Setting a ton of variables that may or may not be null. Try set?

Hello,

I am parsing data from JSON into gameobjects and sometimes some information is missing. This leads to either the object being skipped or breaking the script. Is there a way to make it so that I can set the non-null variables and set a placeholder for the null ones?

Code (CSharp):

1. void InstantiatePlanes(IList<FlightData> flightslist)
2.     {
3.         foreach(FlightData flight in flightslist)
4.         {
5.             try
6.             {
7.                 MeshFilter p = Instantiate(plane);
8.                 double relativeBearing = GetBearing((double)flight.lat, (double)flight.lng);
9.                 Variables.Object(p).Set("hex", flight.hex);
10.                 Variables.Object(p).Set("flag", flight.flag);
11.                 Variables.Object(p).Set("reg_number", flight.reg_number);
12.                 Variables.Object(p).Set("lat", flight.lat);
13.                 Variables.Object(p).Set("lng", flight.lng);
14.                 Variables.Object(p).Set("alt", flight.alt);
15.                 Variables.Object(p).Set("dir", flight.dir);
16.                 Variables.Object(p).Set("speed", flight.speed);
17.                 Variables.Object(p).Set("status", flight.status);
18.                 Variables.Object(p).Set("aircraft_icao", flight.aircraft_icao);
19.                 Variables.Object(p).Set("distance", flight.distance);
20.                 Variables.Object(p).Set("offset", offset);
21.                 Variables.Object(p).Set("relativeBearing", relativeBearing);

partial code snippet

I'd rather not put a try/catch for every single one of those set methods, but if I need to I will if there isn't a better option.

 

Not sure what the signature of this Set method is, but you could likely encapsulate it in a method that takes a string and a

Func<T>

delegate, and have your try/catch in said method.

 

I'll give it a shot, thanks!

 

You can use the Newtonsoft Json Unity Package, which has JObject that lets you iterate over key-value pairs (it implements IDictionary<K,V> so it has TryGetValue too).
