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.

@InfernalVII. Maybe the projectile has too less explosion power. You can try to increase it by modifing the projectile entry like described here

@Gman104020 This plugin has no additional griefing features :). However not all protections plugins handle explosion events correctly if the entity is null. I use Worldguard with the 'otherexplosions' flag. Works pretty well for me.

@jdawgerj515 This is a very old config file of cannons. In the new version you have several files for cannon designs, projectiles and a main config.

@gaddi21 About the aiming mode. You must be close the the firing trigger (torch), else it will disable the aiming mode. However i increase now the range of the aiming mode, because it was a little bit too close.

You can test this file

@Drazhar753 I have to say, the tutorial must be updated I know that. But I had no time to do that. To turn the range display of there is no possibility at the moment. I will add some.

@jdawgerj515 I will check the files later when I have more time

Here is the config file you requested: http://pastie.org/8152465

The permissions plugin is Group Manager (Buggy but works just fine) Here is the groups.yml file for GM: http://pastie.org/8152468

I can tell you right now that the permissions is not the issue. I have OP override enabled so it should have worked for me but just in case I gave Soldier permission group the new node of "cannons.build" which I didn't have before.

Is there any way to turn off the projectile distance text? I tried deleting it but it remakes it. I remade the gravel projectile and it fires 20 shots at once, that scatter, and naturally the chat box is spammed with the distances of each shot.

It doesn't seem to have worked, tried what you said, also replaced the file and still nothing. I gave myself all the permissions to make sure, I don't understand the new config either. The old one used to show the block type the cannon was made of etc and allowed you to change it, as well as a list of the projectiles. I checked the projectiles config but there was only 'cobblestone.yml'

Edit: Ok so it is actually working, I just wasn't aware the length was now 3. So how does one go about changing things such as block type, I'd like the cannons to require to be made of Iron Blocks as opposed to wool.

Edit2: Ok so after following the tutorial I've created my own type of cannon, which is good. However one problem I ran into that you may want to update is that in the tutorial it shows 'redstone wire' as part of creating the cannon, however that didnt work and caused my custom schematic to not load. Upon loading the classic schematic, that had redstone repeaters, sure enough using those worked. So just saying the pictures were a little misleading, but glad to have it worked out now.

Is this working with 1.6.2?

Because I type /cannons and it brings up the usual commands and whatnot but cannons don't actually work. Tried deleting the config and creating a new one but it created it with half of the info missing : /

2013-07-18 00:31:19 [INFO] [Cannons] Loading projectile configs 2013-07-18 00:31:19 [INFO] [Cannons] Loading cannon designs 2013-07-18 00:31:19 [SEVERE] [Cannons] Schematic not loadable 2013-07-18 00:31:19 [SEVERE] [Cannons] Error while loading schematic plugins/Cannons/designs/classic.schematic :java.lang.NullPointerException; does file exist: true

Is what appears in the server log. I may have to reinstall from scratch, I'll try that soon, can't atm. But I'm assuming that it isn't compatible.

@tt_the_king The actual firing angle is 'default vertical' + 'adjusted vertical'. So it should fire in the sky, even if it says 0deg. Does it fire with an certain angle?

Hello

I'm trying to set up this plugin.
Everyting works fine, except the "defaultVerticalAngle" property isn't beeing used.
Everytime I build the cannon, the vertical angle starts at 0.

Here are the settings.

angles: defaultHorizonatalFacing: west defaultVerticalAngle: 45.0 maxHorizontalAngle: 0.0 minHorizontalAngle: -0.0 maxVerticalAngle: 46.0 minVerticalAngle: 44.0 angleStepSize: 1.0 angleUpdateSpeed: 1.0

@ariodsenuke There is an way, but it is not described in the documentation of worldedit. Use the ingame command to figure out how it is written. It should be a flag called 'other', which deny all explosions from other sources.
http://dev.bukkit.org/bukkit-plugins/worldguard-explosion-flags/pages/explosion-types/

@MozartMozart1000 Like already mentioned you have to make your own cannon. Load the cannon .schematic with worldedit and modify it. More can be found here:
