Accessing class variables from a definition

A class can have a constructor, in which you specify the values of the fields in that particular instance of the class object. For example:

     public class Temp {
         public int field;
             
         // constructor
         public Temp(int field) {
             this.field = field;
         }
     }

     // create new Temp object with field set to 2
     public Temp tempObj = new Temp(2);

You can do this with your Job class, like so:

 public class Classes : MonoBehaviour {

     [System.Serializable] // display values in inspector
     public class Job {
         public int jobID;
         public string name;
         public string shortDesc;
         public string longDesc;
         public int attPlus;
         public int magPlus;
         public int abiPlus;
         public int spdPlus;
         public int lckPlus;
         public int defPlus;
         public int mdfPlus;
         public int hpPlus;
 
         // constructors

         public Job() { } // empty constructor, use default values

         public Job(int jobID, string name, string shortDesc, string longDesc,
             int attPlus, int magPlus, int abiPlus, int spdPlus, int lckPlus, int defPlus, int mdfPlus, int hpPlus)
         {
             this.jobID = jobID;
             this.name = name;
             this.shortDesc = shortDesc;
             this.longDesc = longDesc;
             this.attPlus = attPlus;
             this.magPlus = magPlus;
             this.abiPlus = abiPlus;
             this.spdPlus = spdPlus;
             this.lckPlus = lckPlus;
             this.defPlus = defPlus;
             this.mdfPlus = mdfPlus;
             this.hpPlus = hpPlus;
         }
     }

     // create new Job object
     public Job Samurai = new Job(
         1, "Samurai", "A warrior with high speed and ability with a katana.", "",
         1, 0, 3, 5, 3, 0, 0, 4);
 }

Or during runtime, you can change the values of a Job object.

 class OtherScript : MonoBehaviour
 {
     void Start()
     {
         Job samurai = new Job();
         samurai.jobID = 1;
         samurai.name = "Samurai";
         samurai.shortDesc = "A warrior with high speed and ability with a katana.";
         samurai.attPlus = 1;
         samurai.magPlus = 0;
         samurai.abiPlus = 3;
         samurai.spdPlus = 5;
         samurai.lckPlus = 3;
         samurai.defPlus = 0;
         samurai.mdfPlus = 0;
         samurai.hpPlus = 4;

         Debug.Log("Samurai job description is: " + samurai.shortDesc);
     }
 }
