Yes my bad for the very late response 

import org.dreambot.api.methods.filter.Filter;
import org.dreambot.api.methods.map.Area;
import org.dreambot.api.script.AbstractScript;
import org.dreambot.api.script.Category;
import org.dreambot.api.script.ScriptManifest;
import org.dreambot.api.wrappers.interactive.NPC;

@ScriptManifest(author = "You", name = "CowKiller", version = 1.0, description = "Simple CowKiller", category = Category.COMBAT)
public abstract class CowScript extends AbstractScript {
    public static final Filter<NPC> COWFILTER = new Filter<NPC>() {

        @Override
        public boolean match(NPC npc) {
            if (npc == null) {
                return false;
            }
            if (npc.getName().equals("Cow") && !npc.isHealthBarVisible()) {
                return true;

            } else {
                return false;
            }
        }
    };

        Area CowArea = new Area(3209, 3302, 3192, 3282);

        @Override
        public int onLoop() {
            if (getLocalPlayer().isInCombat()) {

            } else if (CowArea.contains(getLocalPlayer())) {
                NPC cow = getNpcs().closest("Cow");
                if (cow != null) {
                    cow.interact("Attack");
                }

            } else {
              getWalking().walk(CowArea.getRandomTile());
            }
            return 1000;

        }
}

 

Eclipse doesnt seem to be registering any errors in it

public abstract class CowScript extends AbstractScript 

You declared your class abstract. You can't instantiate an abstract class. That's why you get " java.lang.InstantiationException" in the debug console.
