Sign click event

I just don't get it why this doesn't work. I have no errors in the code but it doesn't wanna load the plugin, did I do the plugin.yml wrong?

Code:java

 @EventHandler
public void playerInteractEvent2(PlayerInteractEvent event) {
 
if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
 
if (event.getClickedBlock().getType() == Material.SIGN) {
Sign sign = (Sign) event.getClickedBlock().getState();
Player player = event.getPlayer();
 
if (sign.getLine(0).equalsIgnoreCase("test")) {
sign.setLine(0, ChatColor.DARK_RED + "[Test]");
player.sendMessage(ChatColor.DARK_RED+ "[Testing] " + ChatColor.BLUE + "Hello");
}
}
}
}

EDIT: Plugin.yml

Code:

name: TestPlugin
main: me.FroddeB.Youtube
version: 1.0
description: >
            Test Plugin, Right click a Sign.
commands:
  test:
    description: Hello

 

Have you registered Event?

 

You are checking the wrong material. Use SIGN_POST and WALL_SIGN. SIGN is for itemstacks

 

Didn't work..

This is the loading error. I just cant find anywhere in the error where it says why..

Your plugin.yml is wrong.
The main should be like this
me.name.youtube.NAME OF THE MAINCLASS

Try using this (if your main class is named youtube):

Code:

name: TestPlugin
main: me.FroddeB.Youtube.youtube
version: 1.0
description: Test Plugin, Right click a Sign.

commands:
    test:
        description: Hello

 

Your main point is wrong. I has to be "package path and class name that extends JavaPlugin.
Example:
package: me.FroddeB.Youtube
class name: Youtube
main point: me.FroddeB.Youtube.Youtube

 

Is the main class for your plugin (where the onEnable() method is where you also register the listener) named Youtube?
Is it also in the me.FroddeB package?

EDIT: Seadragon91 beat me lol I hope my message might help anyway

 

So like this?

Code:

name: TestPlugin
package: me.FroddeB.Youtube
class name: TestPlugin
main: me.FroddeB.Youtube.TestPlugin
version: 1.0
description: >
            Test Plugin, Right click a Sign.
commands:
  test:
    description: Hello

 

if you remove the package and class name keys

 

Thank you now it loads except it doesn't do anything :/ (Sorry I am new to Java and Bukkit Plugins)

 

Did you register the event?

 

Register the listener you mean?


Also, OP, I recommend checking out some online Java beginning tutorials like thenewboston. You may also consider purchasing a Java book which may help you start out.
I learnt Java really easily because of prior knowledge to similar languages and syntax. You also gotta have some Java knowledge before starting Bukkit plugins.
I hope you get your plugin working and good luck with your future endeavours.

 

Sorry I don't get that, how do I register the event? xD (Sorry because of my newbie attitude)

EDIT: is it like?

Code:java

Bukkit.getServer().getPluginManager().registerEvents(this, this);

 

Yes. But the first paremeter is the listener and the second is the plugin. So keep "this" for the second paremeter if this is being called in the onEnable() method. Change the first paremeter to an instance of the listener class or keep it to "this" if the listener is part of the same class.

EDIT: Take a look at this.

EDIT 2: Sorry I keep editing it like 6 times, I kept pasting a facebook link instead of the desired one xD

 

Couldn't make the plugin work even after registering it, thanks anyways guys!

 

I got it to work.
The "setline" doesn't work, you must remove the ChatColor.DARK_RED. Also, you must take an event of it's own.
And yeah, your plugin.yml didn't work either.

Code:java

 public void onEnable() {
Bukkit.getServer().getPluginManager().registerEvents(this, this);
}
 
@EventHandler
public void playerInteractEvent(PlayerInteractEvent event) {
if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
if (event.getClickedBlock().getState() instanceof Sign) {
Sign sign = (Sign) event.getClickedBlock().getState();
Sign s = (Sign) event.getClickedBlock().getState();
if (s.getLine(0).equalsIgnoreCase("test")) {
sign.setLine(0, "§3[Test]"); //This part must be registered as it's own event for the text to actually change
event.getPlayer().sendMessage(ChatColor.DARK_RED + "[Testing] " + ChatColor.BLUE + "Hello");
}
}
}
}
}

Code:

name: TestPlugin
main: me.mrtang.testplugin.TestPlugin
version: 1.0
description: Test Plugin, Right click a Sign.
 
commands:
    test:
        description: Hello

Try fix up your code, and try again.

 

Thank you for helping me!

 

got the sign update to work but you have to get 2 event handlers.

Code:java

@EventHandler
public void playerInteractEvent(PlayerInteractEvent event) {
if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
if (event.getClickedBlock().getState() instanceof Sign) {
Sign sign = (Sign) event.getClickedBlock().getState();
Sign s = (Sign) event.getClickedBlock().getState();
if (s.getLine(0).equalsIgnoreCase("test")) {
sign.setLine(0, "§3[Test]");
sign.update();
event.getPlayer().sendMessage(ChatColor.DARK_RED + "[Testing] " + ChatColor.BLUE + "Hello");
}
}
}
}
 
@EventHandler
public void playerInteractEvent(PlayerInteractEvent event) {
if (event.getAction() == Action.RIGHT_CLICK_BLOCK) {
if (event.getClickedBlock().getState() instanceof Sign) {
Sign sign = (Sign) event.getClickedBlock().getState();
Sign s = (Sign) event.getClickedBlock().getState();
if (s.getLine(0).equalsIgnoreCase("§3[Test]")) {
event.getPlayer().sendMessage(ChatColor.DARK_RED + "[Testing] " + ChatColor.BLUE + "Hello");
}
}
}
}
