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.

Could you also add a whitelist mode option for player targets? Like, it will target all of the players, except the ones in the list (i.e. admins or players who built the cannon & their friends/allies)

Also, did you have a good time during your vacation? :D

Back from my 2 week vacation.

@TheZerok666 It is definitly planned to target players too, but it will take me some time to implement commands to add and remove players from the target list.

@JaffaMC And TNT is doing damage? There is the BlockExplodeEvent for spigot 1.8.3+ but it would prevent blocking of explosions, instead of blocking them all. Have you tried to set relayExplosionEvent: True?
https://github.com/DerPavlov/Cannons/blob/master/src/main/resources/config.yml

@GodsDead Just one type of gunpowder is possible, either named or unnamed. Mixing is not possible anymore. I can also add a list of gunpowders, but it will break all your design files. Maybe it is possible to test first if it is a list. How important is this for your server?

@joshfow Difficult to tell, you can send me your server than I can have a look. Make sure you have WorldEdit, since Cannons will not load without it.

@robotnikthingy I think you have a sentry in a no existing, or different world. Probably a bug on my side.

Is there any way to make the sentry cannon target players too? I'd love to make some sentry cannons for my fort so that players can try to destroy it

Hey, cannons aren't doing any damage in WorldGuard regions. other-explosion is not DENY. The regions do not even have the other-explosion flag. Even if I set it to ALLOW, cannons do not do damage.

Im falling behind on my updates, sorry.

How do I set multiple gunpowders? I want to use normal SULPHUR & named SULPHUR. Do I separate them with a commer? gunpowderType: 'SULPHUR:0'

I'm running Spigot 1.8.7 (2015-07-21a) with Cannons 2.3.3. Whenever you do anything that should create a message, no message comes up. Such as when you create a cannon, the older versions popped up a message that said "Your cannon was created successfully" or something like that. There is nothing in the console or logs. I have tried Spigot 1.8.5 and an older version of 1.8.7 but neither produces a message. Was this taken out of the newer cannon versions? It's hard to tell if you need to clean it or if it needs ammo and such when you are trying to fire them.

There isnt a 2.3.3 it only goes upto 2.3.1, I can't update my java as im on a shared host. I will message the host if you are 100% certain that they are still using the long outdated Java 6, Im sure the latest WE needs a newer Java and that works?

@GodsDead You have Java 6. For this you need 2.3.3 where this problem is fixed. Or just update your Java.

@Rulerish That no error, just a warning that the plugin creates a new table in the database. Next restart it should be gone.

@Termite117 Can you send me the part of the log file with the error. Just post it on Pastebin.com and give me the link.

Can you also check the following:

Do you have Worldedit. Cannons will not run without it.
Is your server version > 1.8.3. If you need an older version, let me know
