Best way to learn Java.

Who are we checking isOp() on? Figure that out and get an object of that type.

Player

 

I did, but I still is error?
What are you thinking that the code is?
Maybe I am misunderstanding it?

 

for (Player p : getServer().getOnlinePlayers()) {
if (p.isOp()) {
sender.sendMessage("Hey, this guy is an admin! " + p.getName());
}
}

 

:O I was way off.... I suck

That seems to work, I am going to edit this and try and make it work with permission plugins, because not all admins have OP
EDIT Just tried it, but it just echoes the command

Alright. That's your choice.

 

Here its 1000€ :S!

 

I think the best way to learn things is to actually try to figure out how to do them. A week ago, I did not know java at all. I looked through java tutorial and then plugin tutorial, then I browsed this forum a bit and put together my first plugin. Code might not be the best, but it works. (at least I think it does)

 

You don't need to depend on another plugin to check if someone has permission. In fact if you are not using sub commands, and you should not for your first plugin, you don't even need to check if someone has permission. If you declare in plugin.yml that a command a permission bukkit will automatically check them at no extra work to you.

 

You see, thats too easy, I want not so easy

 

It seems that at this point you have picked up the syntax of Java. What you lack is the architecture skills behind it to make it work. You really do need to understand instances, objects, pointers, etc.

The hard part about programming was never describing to the computer how to solve a problem. It has always been figuring out a way to get the computer to solve the problem.

 

And that children, is why plugins that should take a day to make take a week.

 

Or a month, or a year, or never get made because of the endless raging.

 

That happens when you don't return correctly.

 

I did, fml

 

Well after your first plugin everything else comes much easier. Programmers are lazy. If there is a plugin that can share even 1 byte of code with another plugin you made, you will do so. My plugin CrimsonStone and my indev plugin Storm already use basically the same code for 4 classes, and alot of Storm's classes are the same but with slight modifications. Once you a base of code that you know how to use, alot of your programming will be copy + pasting and changing variable names.

 

Use return true; after you finish your command

 

Icyene
OK I do, and I get spammed with errors. I mean I know there has to be a way, I just don't know it.
Here is my idea, not in code, but how it would work:
using pex (for now) find a user in a group, if the user is in the group and online, when you do /<groupname> He will appear. That wasn't the best let me try again: /Admin lists all online admins by finding anyone within the group Admin, online. Better?

 

IF you get spammed with errors, read the errors, most of the time they tell you what exactly is wrong. Also Fix one error at a time, normally the one that happens first.

 

I get spammed with errors in eclipse, they dont say anything but can't do it basically.

 

did you read the problems/markers tab?

 

Yep! I can't get it, I can't get any useful help, so I am done with it! I suck at Java, and I can't even make a simple freaking plugin, so why should I continue?

 

You have it backwards, learn java first, then make plugins. Making plugins while learning java only makes life more difficult. As for the errors, the Internet will translate the technical description to something you can understand, but unless you post your problems, no one but you knows what they are (don't lose theory of mind).

 

I deleted it in a rage. I took java for a month, then started bukkit, still can't do it. I guess this just isn't my thing.

 

A month is an incredibly short amount of time if you have only just began learning how to program.

 

Nah I didn't just learn how to. I moved it to PlugReqs because I am still not sure what to do. OK now one more thing before I completely give up, could you help me make it? If not, then someone else can make it or not, but I cannot seem to.

 

If you post what's wrong and provide code/stacktraces (Errors basically), I'm sure lots of people will love to help, including me (I'll try at least )

 

Same here. Messing around with existing stuff really helps too. The more you do it, the more you understand. My problem right now is understanding Vectors -.-

 

^^Same here! For example, I didn't even know constructors existed until I wanted to use config options from another class.... lol

 

OK code: http://pastebin.com/hN8binEC <--- new link old one was out of date
So when I create the the perms.playerInGroup() thing, nothing is wrong right? But when I save it, everything with Permissions is errored, and so is playerInGroup, what am I doing wrong

 

I jumped into it head first with a fairly large plugin... The harder it seems the faster you will learn. If you get stuck, feel free to ask a ton of questions here, we actually love to answer questions. Also, just reading other code and trying to understand it line by line helps greatly, and can teach you new ways to do things!

EDIT - permissions... if (player.hasPermission("example.permission")){
do something...
}
