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.

@Ajaxan

You have to enable cannons in the ObsidianDestroyer config.
EnabledFor: TNT: true Cannons: true

Super breaker will break obsidian after the amount of hits defined in the config. It should also work on anvils, enchantment tables, and enderchests.

@Dibujaron I have to update the documentation. However I want to finish the cannons 2.0 first. For moving cannons make a sign on the cannon, cannons will do the rest. If it works the cannon name will appear on the sign.

@Ajaxan So the cannonball does no damage to the world. No block can be destroyed. Is TNT blocked in your world. Or maybe you have disables other-explosion with worldguard.

More questions:

Which cannons version do you use?
Bukkit version?
Protection plugins?

So how exactly do i make this plugin work with obsidiandestroyer to allow only certain blocks to break obsidian? Or just really hard without that certain block? @DerPavlov

Tried this but nothing happened. As in the cannonball didn't even destroy normal blocks anymore once i gave it 10 penetration and super breaker. It isn't a big deal as I can find other ways to work around it. What exactly is super breaker supposed to do? Does it just delete the blocks it comes in contact with bypassing TNT checks all together?

@Dibujaron

its quite easy. just put a sign on the side of the gun like you would with a chest, and the plugin will handle the rest. this works for cannons 1.9.4 and up

Hey, I had heard something about this being compatible with movecraft through use of signs somehow. Can you tell me more about that? I can't find documentation anywhere. Thanks!

@Ajaxan I changed the code pretty often the last few months, so I don't really know which possibilty works:

The cannonball acts like TNT. If obsidian destroyer works with TNT it will work with cannons
Cannons does not map the explosion. Set the Cannons option in obsidianDestroyer. However you need a projectile that has superbreaker and penetration. Else nothing will happen.

You have an invalid string in the config, which cannot be read. Possibility on ^ ?

@robotnikthingy There are .yml reader out there, which make the thing really easy. Import the .dll and it should work the same way as for bukkit. If you need help you can contact me.

Also, im going to be testing out my C# programming skills by making a GUI for the cannons plugin to allow people to easily edit the properties of cannons. Hopefully i can get something out in a month or 2

I think i found a bug. it seems like "doesPenetrationDamage" does not do anything at the moment, since eve when set to true, blocks penetrated by a projectile are not destroyed

@Thegameratitude Sry, I don't speak french. My girlfriend tried to translate it and we think that your cannon fires to the left and not straight. Which bukkit version are you using? The directions in bukkit have been changed a few months ago, so maybe your are using an older bukkit version or tekkit.

il n'y a pas des problemes avec le version tres nouveau

EDIT: Vielleicht wäre Deutsch einfacher für dich :)

@robotnikthingy I implementing your comments to my configs. I have to say, they are really good and very accurate. If you are interested in expanding the documentation of cannons, you are welcome.

@Msell22 The plugin can't prevent building a cannon. I can't only break the last block before the cannon is finished. This will be a feature of the new version. However I don't know how it works in the old version.

EDIT: It seems the new version does not check for limits at all
