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.

Which minecraft/server version are you using?

Do you have any mods running?

Do you use a special chest or inventory?

Worst case you can send me a small version of you server and I will test it.

The mortar won't fire. I right click the torch on the mortar when fully loaded and it responds as if i just was adjusting it's angle.

Indeed I missed that one. Go to designs/mortar.yml and replace 'minecraft:torch' with 'minecraft:wall_torch' in the constructionBlocks.

This projectile I made isn't being removed from inventory on usage. All of my other projectiles are subtracted, but this one is virtually infinite.
Any ideas on why?

For me your projectile is loading and subtracting ammo from the chest correctly. Please make sure there are no errors in the log.

Also check if your if the cannon you are using has enabled ammo consumption

ammunition:
  #what the gunpowder is called
  gunpowderName: gunpowder
  #what item is used as gunpowder (minimum is id:data. Named items id:data:displayName:lore1:lore2:....)
  gunpowderType: 'minecraft:gunpowder'
  #does this cannon need gunpowder. If false you can directly load the projectile
  needsGunpowder: true
  #gunpowder will be removed from inventories. If false you have to click the cannon until it is reloaded
  gunpowderConsumption: true
  #if false the cannons will not remove the projectile form the inventory but you still need a projectile
  projectileConsumption: true
  #if true, no item is removed from the players inventory
  ammoInfiniteForPlayer: false
  #if true, the cannons does not consume ammunition for autoreloading with redstone
  ammoInfiniteForRedstone: false
  #whether the cannon can reload from a chest
  autoreloadRedstone: true
  #after firing the projectile are usually gone, but you can set this to false to keep the cannon loaded. Just load the cannon once and it stays loaded until you break it.
  removeChargeAfterFiring: true
  #after creating a cannon it will be preloaded with the maximum amount of gunpowder and the default projectile (first in the list)
  preloaded: false

I don't use a chest, all I do is load it in manually. But it doesn't take the emeralds from me... I'll keep trying with some diferent cannons and maybe a diferent item ID since this one doesn't seem to want to be substracted.

Just using a normal wool cannon with presumably default ammunition configuration:

I found the problem in your design file. Please replace "ENTITY_IRONGOLEM_ATTACK" with "ENTITY_IRON_GOLEM_ATTACK" and it will work.

Also enable the debugMode in the config.yml to display more details in case of a problem.

There seem to be some changes in 1.14 which requires some changes in my code. I will try to update it as soon as possible.

Hey there DerPavlov, it seems Cannons 2.5.3 is incompatible with the latest version of FastAsyncWorldedit for 1.13.2. The plugin loads correctly, but nothing happens when you create a cannon - its as if the plugin isn't installed. There are no errors whatsoever at any stage of the process. However, it functions perfectly when FAWE is replaced with the latest version of the regular WorldEdit.

Normally I would simply downgrade to regular WorldEdit, but FAWE has quickly become a standard and essential plugin for most servers. I wish I could provide more details as I understand it would be difficult to debug this issue without them, but there aren't any - my personal hunch is that it has something to do with FAWE's API not being exactly the same as WE's. Is it possible to investigate this

I was just about to report this myself, the isse I reported on my previous message has 100% to do with this issue.

Luckily I can just remove FAWE on my Factions server, so I can workaround this.

It seems the latest version of FAWE still does not use the new BlockVectors of Worldedit. There is actually not much I can do about it.

They claim they fixed the issue 10 days ago, lets wait for the next release.

https://github.com/IntellectualSites/FastAsyncWorldEdit-1.13/issues/62

However, when I import FAWE in my project it claims BlockVector3 does not exist.

You could try Async WorldEdit as an alternative:

Having a sudden issue where cannons are apparently uninteractable.

The plugin loads fine, everything seems fine. Even premade automatic cannons are working, you just can't select cannons for purchase or inspection.

I activated the debugging and no interesting info is being shown on click. My suspicion is that some other plugin may be interfering somehow, but I just removed all plugins except LuckPerms, WorldEdit and Fawe, and the issue still persists.

Cannons v.2.5.3

Can you send me a version of you server with config and the plugins you suspect? I will try to find the issue.

Thanks a lot for that. Will do some localhost testing before I actually send you anything, just for issue confirmations.
