Cannons

Table of Contents

What can it do?

Cannons is a highly configurable plugin which allows you to fire block build cannons. It is possible to aim and load different amounts of gunpowder to hit targets at different ranges. The power of redstone makes it possible to set the gun to auto load and activate the rapid fire mode. Choose your projectile from a broad spectrum of cannonballs and smash the enemy.

With Cannons 2.0 you are also able to design your own cannons using .schematic files and give each cannon their own settings, as well as different types of projectiles.

Features

Build a cannon out blocks
Design your own cannon and save it as .schematic
Design and fire different projectiles to smash your enemy
Use redstone to fire guns from distance
Rapid fire with auto-load possible
Destroyed blocks can be restored with CreeperHeal (if 'custom' option is true)
Cannons will stay load and aligned due to the database
Movement plugins (e.g. Movecraft) are supported if a cannon has a sign to store a tag
API for ships plugins (e.g. iSails) to use cannons on ships without signs.

@laclongquan No problem. I have also deleted many plugin if the are not working on the first try :) To make a nuke choose a material you want to use and add it to the 'allowed projectiles' list so you can load it. Copy a property entry and name it the same way like the list entry. Than increase the 'explosion power'.

No, no, no, my apologies, DerPavlov. After update, it works very well. Keep up the good work! It'd be cool if there was a secret "nuke" type ammo! Also, how to fire the gun using redstone?

@laclongquan That your decision if you don't want to use a plugin. I am also not very happy with the stability and a few bugs made it into the release. So sorry about that. I am really very happy if I can help you guys if a problem occurs. But you must help me and give me feedback. But please be so kind and post me the error messages. This helps me really. I have to guess your log is filled with 'Wrong language'. It was not so a good idea to use special characters. That happens if you have no linux system to test it :)

Sorry about not replying right away, DerPavlov. I might update my Cannons. The problem was, one, my console got completely filled with errors and it sometimes even caused it the crash. Two, if it didn't crash, creation of cannons was NOT POSSIBLE. In the end, I chose to simply send the Plugin straight to my recycle bin... BTW, I didn't edit the config. EDIT: I updated the plugin and it works.

@bigloloraf There can be many reason for this. Maybe you use a protection plugin which prevents explosion. Towny, faction, ... will cancel all explosion events in protected areas and there will be no explosion. If you don't know which plugin is interfering or you are sure that there is a bug, please send my a .zip of your server and I am going to test it. Please delete the world to keep the file small.

@Virusbomb If you use the latest version this should work. Maybe if something is canceling the explosion event this will also prevent you from teleporting. But if you see an impact this will probably be a programming thing. You can also send me your server files if you want.

@B1ade92 Movecraft API is coming in v2.0 so the cannons can be fired in moving aircrafts. This will be the biggest part of the next version.
Also a more realistic behavior is planed. So cannons move 1 block back and move forward before you can fire. Maybe I will also disable aiming when the cannon is not in firing position. The cannon will scramble the angles after firing and there will be a loading from the front feature. But this will be all configurable in the config. So you can turn it off and on.
Buying cannons is also very interesting so a economy implementation will come also. But for this I have to save cannon locations and at the moment I have no idea how to implement it :)

@B1ade92 You remind me to make a video about that. But you can add items to the config. There is a list with items ('allowed projectiles') which can be loaded in the cannon and below you have the properties of these. You have to use the same name for list entry and property. The name of the item you can find here:
http://dev.bukkit.org/server-mods/block-cannons-v1-1/pages/installation-and-configuration/configuration/

For a autofire cannon place a chest next to the block with the torch and a redstone torch underneath the barrel. Load the cannon with gunpowder and a projectile. Don't forget to take cover :)

There's a small error on the console when players are firing TNT with the cannon.

12:49:27 [WARNING] Task of 'Cannons' generated an exception java.lang.NullPointerException at at.pavlov.Cannons.FireCannon2.run(FireCannon.java:249) 12:49:29 [WARNING] Task of 'Cannons' generated an exception java.lang.NullPointerException at at.pavlov.Cannons.FireCannon2.run(FireCannon.java:249)

The cannons are built inside a worldguard region, block damage is turned off in the cannons config.

@Katorone Ok, no problem. I am going to update the version so the .yml should work.

@DerPavlov : I've tried both the custom files, and only the second one (https://dl.dropbox.com/u/16404245/CustomLanguage.yml) is working. The other language files gives the same errors as displayed earlier. I would have tested this earlier, but I was unable to get in-game, the commands didn't work from the console so I couldn't test it through there.

Oh, my bad... Apparently the default value for language is 'custom'. I didn't think about changing it to English. Restarted the server and all is well now. :-D Thanks !

Ok, guys so many at once :) . Please try to set 'language: english' in the config. I hope this fixes the problem with the config. If this works there is a problem with the config and I don't know why it works for me.
Now lets gets CustomLanguage working. Try to switch back to custom, load the config below and reload the server
https://dl.dropbox.com/u/16404245/Cannons%20Sprachdateien/English/CustomLanguage.yml

If not, try this one
https://dl.dropbox.com/u/16404245/CustomLanguage.yml

I think there is a problem with the ° character I use.

When using cannons on the latest bukkit build, I'm getting this error: http://dev.bukkit.org/paste/5545/

CustomLanguage.yml is empty. Even when I fill it with the example here and /cannons reload, the errors keep appearing and CustomLanguage.yml is again empty.

See this error, in server log:

[SEVERE] Cannot load configuration from stream org.bukkit.configuration.InvalidConfigurationException: unacceptable character 'ï¿½' (0xFFFD) special characters are not allowed in "<string>", position 718 at org.bukkit.configuration.file.YamlConfiguration.loadFromString(YamlConfiguration.java:55) at org.bukkit.configuration.file.FileConfiguration.load(FileConfiguration.java:138) at org.bukkit.configuration.file.YamlConfiguration.loadConfiguration(YamlConfiguration.java:202) at at.pavlov.Cannons.UserMessages.reloadcustomLanguage(UserMessages.java:403) at at.pavlov.Cannons.UserMessages.loadCustom(UserMessages.java:292) at at.pavlov.Cannons.UserMessages.loadLanguage(UserMessages.java:71)

I've deleted CustomLanguage.yml file, and restarted the server it just creates a zero byte size empty file, and suggestions?

Many thanks.
