[Help] Adding somethings to Plugin

Hello everyone!

I am trying to add a toggling command to my plugin FlashlightPlus but not really sure how.

Another thing I am trying to accomplish is when the Flashlight is on mobs will not spawn in the configured distance(In Blocks) away.

FlashlightPlus.java

Code:java

package com.hybrah;
 
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
 
 
public class FlashlightPlus extends JavaPlugin {
 
    public void onEnable() {
        this.getConfig().options().copyDefaults(true);
            getServer().getPluginManager().disablePlugin(this);
            return;
        }     
        public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
 
            if(cmd.getName().equalsIgnoreCase("Flashlight") || cmd.getName().equalsIgnoreCase("flash") || cmd.getName().equalsIgnoreCase("fl")) {
 
                if (!(sender instanceof Player)) {
                    sender.sendMessage(ChatColor.RED + "Must be a player to exucute this command!");
                    return true;
                }
 
                if (!sender.hasPermission("flashlight.use")) {
                    sender.sendMessage(ChatColor.RED + "You do not have permission to perform this command!");
                    return true;
                }
 
                if(args.length <= 0){
 
                    sender.sendMessage(ChatColor.GREEN + "/flashlight on - Turns Flashlight ON!");
                    sender.sendMessage(ChatColor.GREEN + "/flashlight off - Turns Flashlight OFF!");
 
                    return true;
                }
 
                if (args.length == 1) {
 
                    if (sender instanceof Player) {
                        Player player = (Player) sender;
 
                        if(args[0].equalsIgnoreCase("on")) {
                            player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, Integer.MAX_VALUE, 0));
                                sender.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("FlashlightOnMsg")));
                                return true;
                        }
                        if(args[0].equalsIgnoreCase("off")) {
                            player.removePotionEffect(PotionEffectType.NIGHT_VISION);
                                sender.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("FlashlightOffMsg")));
                        }
                    }
                }
            }
            return true;
    }
}
 

I know I’m going to need to remove some code in-order to have the toggling command feature.

Thanks in advance,

The toggling is easy. Replace lines 46-54 with

Code:java

if(args[0].equalsIgnoreCase("on")){
    player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, Integer.MAX_VALUE, 0));
    sender.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("FlashlightOnMsg")));
    flashlightOn = true;
    returntrue;
}
if(args[0].equalsIgnoreCase("off")){
    player.removePotionEffect(PotionEffectType.NIGHT_VISION);
    sender.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("FlashlightOffMsg")));
    flashlightOn = false;
    return true; //You forgot to add this
}
if(args[0].equalsIgnoreCase("toggle")) {
    if(flashlightOn){
        player.removePotionEffect(PotionEffectType.NIGHT_VISION);
        sender.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("FlashlightOffMsg")));
        flashlightOn = false;
        return true;
    } else {
        player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, Integer.MAX_VALUE, 0));
        sender.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("FlashlightOnMsg")));
        flashlightOn = true;
        return true;
    }
}

and finally add on line 13:

Code:java

boolean flashlightOn = false;

For the spawn radius, take a look at CreatureSpawnEvent and check that the location is further than your range, and if not, cancel it. If you want your range to be a sphere rather than a cube, make a vector between the entitylocation and the player location, and then check the length against your range
