LBApi.java:21

Code:

plugin.mysql.createBan(name, admin, type, unban, reason);

Full createAutoBan Method

Code:

    public static void createAutoBan(String name, String admin, String type, String unban, String reason){
        plugin.mysql.createBan(name, admin, type, unban, reason);
       
    } 

LegendaryOreLogs.java:42

Code:

LBApi.createAutoBan("Player", "LegendaryOreLogs", "0", "", "AutoBan: Xray");

 

It would probably help if we had all of your class to work with...

And I don't know/have used the LBApi before. I have no idea what it does. If it has javadocs, it should tell you what you did wrong.

 

No it doesnt have java docs and you dont know what it is cuz i created it yesterday ill give you both classes

LBApi

Code:

package me.icyrelic.com.API;

    static LegendaryBans plugin;
    public LBApi(LegendaryBans instance) {
 
        plugin = instance;
 
        }
   
   
    public static void createAutoBan(String name, String admin, String type, String unban, String reason){
        System.out.println("Start");
        plugin.mysql.createBan(name, admin, type, unban, reason);
        System.out.println("Done");
       
    }
   
    public static void sendBanMessage(String admin, String reason, Boolean tempban, String tempbantime, String player){
       
        if(tempban){
            plugin.getServer().broadcastMessage(ChatColor.YELLOW+player.toLowerCase()+ChatColor.GOLD+" was tempbanned by "+ChatColor.YELLOW+admin+ChatColor.GOLD+". Reason: "+ChatColor.YELLOW+reason);
            plugin.getServer().broadcastMessage(ChatColor.YELLOW + player + ChatColor.GOLD + " is temporarily banned for " +ChatColor.YELLOW+  tempbantime);

Your if else in your API looks a bit dodgy, why not 2 if's like if (tempban) and if (ban)

And I see a onEnable but no onDisable

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

you dont need one

Any suggestions?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

You are getting a Null Exception Error because tempban has no Value so by Default, it has set it to null.
If i was you, I would put boolean tempban on a new line and then give it a value of true or false.

 

But it should still work the way it is because in the LegendaryBans tempban command i have

plugin.mysql.createBan(player, sender.getName(), "1", ""+z, reason);

and in the ban command i have

plugin.mysql.createBan(player, sender.getName(), "0", "", reason); //This one works 100% fine

its null there too and it should work fine

 

You are calling the methods that use "plugin" statically, so "plugin" is not initialized.
Instead of using them that way, initialize a new instance of LBApi in your onEnable.

 

You are getting a NullPointerException because plugin.mysql.etc doesn't point to anything...

By that, I mean I don't see a single public variable in your main class named "mysql". Also, plugin looks like it may not mean anything either, since you are calling a static method in a class, which then leads back to a main class that you have not passed to it either.

You would want to do something like this, and get rid of the static in the methods within LBApi.

Code:java

 
    private LBApi api;
 
    @Override
    public void onEnable() {
 
        api = new LBApi(this);
 
        api.createAutoBan("Player", "LegendaryOreLogs", "0", "", "AutoBan: Xray");
        api.sendBanMessage("LegendaryOreLogs", "AutoBan: Xray", false, "", "Player");
 
 
        getServer().getPluginManager().registerEvents(new blockbreak(this), this);
        getCommand("orelogs").setExecutor(new orelogs(this));
        sendMsg();
        resetLists();
    }
 
    public LBApi getAPI() {
        return api;
    }
 

 

any new suggestions

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

What is your main class for the plugin, LegendaryBans, or LegendaryOreBlocks? You don't need two classes that extend JavaPlugin

 

these r 2 different plugins trying to work together and yes there is 2 working plugins
the only thing that doesnt work is the api

 

Still need help
