Java8 new JavaScript scripting engine Nashorn Small test

A very detailed description of the Nashorn scripting engine: http://winterbe.com/posts/2014/04/05/java8-nashorn-tutorial/

Here is a small example of my test that simulates the scripting of damage calculations in the game:

Scripttest.java:

Package com.zl1030.scripttest;import java.io.filereader;import javax.script.invocable;import  javax.script.scriptengine;import javax.script.scriptenginemanager;public class scripttest  {    public static void main (String[] args)  {         try {             scriptenginemanager factory = new scriptenginemanager ();             ScriptEngine engine =  Factory.getenginebyname ("Nashorn");             String scriptpath = system.getproperty ("User.dir")  +  "/scripts/test1.js";             engine.eval (New filereader (ScriptPath));             invocable invocable =  (invocable)  engine;             test1 test1 = invocable.getinterface ( Test1.class);             scriptresult result  =  (Scriptresult)  test1.calc (New a (),  new a ());             system.out.println (Test1.getlength ("ABCDEFG"));             system.out.println (Result.getdamage ()  +  "   " + result.gettarget (). Geta ()  + "   " + result.isresult ());         } catch  (exception e)  {             e.printstacktrace ();         }    }}

Test1.java:

Package Com.zl1030.scripttest;public interface Test1 {public int getlength (String msg);    Public Scriptresult Calc (a A, a b); }

Scriptresult.java:

Package com.zl1030.scripttest;public class scriptresult {    private  a target;    private boolean result;    private  int damage;    public a gettarget ()  {         return target;    }    public void  settarget (A target)  {        this.target =  Target;    }    public boolean isresult ()  {         return result;    }    public  void setresult (Boolean result)  {         This.result = result;    }    public int getdamage ()  {   &Nbsp;    return damage;    }    public  Void setdamage (int damage)  {        this.damage =  damage;    }}

A.java:

Package Com.zl1030.scripttest;public Class A {private int A = 0;    private int b = 0;    public int Geta () {return A;    } public void SetA (int a) {this.a = A;    } public int Getb () {return b;    } public void Setb (int b) {this.b = b; }}

Test1.js:

var scriptresultclass=java.type (' Com.zl1030.ScriptTest.ScriptResult '); function GetLength (msg) {return msg.length;}    Function Calc (A, b) {A.seta (1);    A.SETB (2);    var result = new Scriptresultclass ();    Result.settarget (a);    Result.setdamage (10);    Result.setresult (TRUE); return result;}
