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.

@der12panzer You mean you can't build a cannon, or you can always build a cannon. I have never tested bukkit permissions, but I will try later. If you are OP you may have all permissions, so deOP first.

@endlessnumber I think turning a ships creates some illegal states for blocks. Therefore cannons can't detect these blocks probably. Maybe the ships developer knows more about this stuff.

I indeed noticed the "move forward" fix. So the question remains, what about moving forward causes the cannon to register properly again, and is there a way to get the re-registration to happen automatically? My theory had something to do with moving the whole schematic into different chunks.

Despite this small problem, we have had a lot of fun making ships and having naval battles on our survival RP server. There's tons of potential for this plugin combo so please let me know if there's any debugging or testing I can do on my end.

@endlessnumber If the signs display something you did it correct. I tested the ships plugin and it makes problems after turning. However moving forward seems to fix the problem. It seems that rotating changes somehow the blocks in minecraft.

Thanks for getting back to me so quickly. Since I didn't say it before, awesome plugin. Yes, I already turned on the required signs, but even after doing so I have this problem. Could I be doing something wrong with the signs? (I place a blank sign on the cannon and it is successfully filled by your plugin with the right stats.)

@endlessnumber Cannon stores the location of a cannon. When you move it, the plugin will create a new one, because the old location entry is not valid. To prevent this place a sign on the side of a cannon. The plugin will store the unique cannon name and the owner of the cannon on this sign and allows the plugin to update the position to the new location.

Does anyone have any idea why cannons only work intermittently when placed on a ship from the Ships plugin? After moving or turning the ship sometimes the cannon will not respond to clicks. But when I list the cannons it stays registered at its old position. This is curious because other times it will update its position just fine.

@der12panzer. Immer noch Probleme? Dann schreib mir eine PM. @InfernalVII You have the wrong construction block for the muzzle. I used a snowblock and you use white wool. To get you .schematic working you can replace the wool with snow or change the .yml to
constructuring blocks:
muzzle: '35:0'
You might also need ports for redstone, chests/signs,...

I don't speak much German unfortunately, despite my mothers side being german :P (I think DerPavlov is from Germany though)

You make your own permissions for projectiles or cannons in each ones config file. Or you can just use the default permissions. here are the permissions to use if you want everyone to use cannons

#for projectile cannons.projectile.cobblestone #to build cannon cannon.player.build #to load cannon cannons.player.load #to fire cannon cannons.player.fire #to adjust or aim cannon cannons.player.adjust #to automatically aim the cannon cannons.player.autoaim #im not sure what this one is for cannons.player.targetTracking #for redstone firing cannons.player.redstone #for automatic reloading cannons.player.autoreload

I use permissionbukkit for permissions

How can I set the plugin so that it allows that the player can build and operate the cannon? What should I do? I can insert any permissions in the normal permission doc., that allowed every command??

If so, how?

Here is the two schematics i have tried

i can also confirm that with the default cobblestone projectile, with explosion radius 2 it still does not destroy anything from the stone wall with 3 gunpowder

@InfernalVII Send me your file I will check it. For too fast projectiles minecraft tends to fire the event when the projectile is already in the 'wall'. If the projectile is super fast the front will be undamaged but the back will be destroyed. Can you verify if the inside of the wall is destroyed?

i already tried to make a 5-block cannon using this tutorial, it was exactly like the classic,schematic but no luck it was not working...

Also about the explosion i figoured out that if i put 2 gunpowder in the cannon the coblestone will destroy a stone wall, but if i put 3 gunpowder it will not

I also just noticed: Cannons do not work with movecraft crates (since they use crates instead of chests). Can you add support for this?
