I 'm going to post here a small release. It is the commands using reflection, and level-controlled by rights:
First of all in MYSQL run this code:
Code:
DROP TABLE IF EXISTS `moopledev`.`character_rights`;
CREATE TABLE `moopledev`.`character_rights` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`characterid` int(11) NOT NULL,
`command` varchar(45) DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
then go to MapleCharacter.java and add this after a ps.close in loadCharFromDB method
Code:
//Load Char rights (for commands)
ps = con.prepareStatement("SELECT * FROM character_rights WHERE characterid = ?");
ps.setInt(1, charid);
rs = ps.executeQuery();
while (rs.next()) {
ret.charRights.add(rs.getString("command"));
}
rs.close();
ps.close();
before "private MapleCharaceter() {" add:
Code:
private List<String> charRights = new ArrayList<String>();
somewhere in MapleCharacter.java:
Code:
public boolean canExecuteCommand(String command) {
if(charRights.contains(command)) {
return true;
} else {
this.message("You can not use this command");
}
return false;
}
Create a new class in client.command called CommandHandler.java
Code:
package client.command;
import client.MapleClient;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
/**
*
* @author BMS2
*/
public class CommandHandler {
public static Object executeCommand(String[] arrayCommand, MapleClient c) {
try {
String command = arrayCommand[0].toLowerCase();
String command2 = command.substring(0,1).toUpperCase() + command.substring(1);
Class<?> commandClass = Class.forName("client.command.handlers."+command2);
Object ins = commandClass.newInstance();
Method method = ins.getClass().getDeclaredMethod("executeCommand",String[].class,MapleClient.class);
method.invoke(ins,arrayCommand,c);
} catch (ClassNotFoundException | InstantiationException |SecurityException | InvocationTargetException | IllegalAccessException | NoSuchMethodException | IllegalArgumentException t) {
c.getPlayer().message("Unable to find this command");
}
return null;
}
}
Now create a new package called client.command.handlers and here you'll create all your classes corresponding to the command name (Starting with first letter uppercase)
example: Spawn.java
Code:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package client.command.handlers;
import client.MapleCharacter;
import client.MapleClient;
import net.server.Server;
import net.server.channel.Channel;
import server.life.MapleLifeFactory;
import server.life.MapleMonster;
/**
*
* @author BMS2
*/
public final class Spawn {
private boolean isPlayerCommand = false; //Useless. Just to know if it is a player command;
public final boolean executeCommand(String[] sub, MapleClient c) {
/*System.out.println("executado");
return true;*/
MapleCharacter player = c.getPlayer();
Channel cserv = c.getChannelServer();
Server srv = Server.getInstance();
if(!player.canExecuteCommand(sub[0])) {
return false;
}
MapleMonster monster = MapleLifeFactory.getMonster(Integer.parseInt(sub[1]));
if (monster == null) {
return true;
}
if (sub.length > 2) {
for (int i = 0; i < Integer.parseInt(sub[2]); i++) {
player.getMap().spawnMonsterOnGroudBelow(MapleLifeFactory.getMonster(Integer.parseInt(sub[1])), player.getPosition());
}
} else {
player.getMap().spawnMonsterOnGroudBelow(MapleLifeFactory.getMonster(Integer.parseInt(sub[1])), player.getPosition());
}
return true;
}
}
Just a few changes in GeneralchatHandler.java
Replace:
Code:
if (heading == '/' || heading == '!' || heading == '@') {
String[] sp = s.split(" ");
sp[0] = sp[0].toLowerCase().substring(1);
if (!Commands.executePlayerCommand(c, sp, heading)) {
if (chr.isGM()) {
if (!Commands.executeGMCommand(c, sp, heading)) {
Commands.executeAdminCommand(c, sp, heading);
}
}
}
with:
Code:
if (((heading == '/' || heading == '!') && chr.isGM()) || heading == '@') {
String[] sp = s.split(" ");
sp[0] = sp[0].toLowerCase().substring(1);
CommandHandler.executeCommand(sp, c);
If you want to give a GM rights to execute a command, you'll need to add the command to the database.
id |characterid |command
1 |30000 |spawn
2 |30000 |online
this is very simple to implement, and I think will be very helpful to set what each GM can do
