Cannons
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.

Posted Jul 13, 2015@ColdFirePower A log file would be helpful (just post it on pastebin.com and post the link). When you get ebean.properties not found then you can ignore it or create a ebean.properties file.
EDIT: Make sure you have worldedit.

Posted Jul 13, 2015@robotnikthingy Can be done. I am not sure if the should be completely disabled, set it to manual fire (you have to assign targets), or just stops reloading. I think I will go for the manual fire option.

Posted Jul 11, 2015Also, is it possible to make it so that when sentry cannons are receiving a redstone signal that they stop firing (when using autoloading)?

I've tried disabling all the fake block indicators in the config but the error still persists. The cannon itself fires just fine though.

Posted Jun 30, 2015@T_X_T Since 1.8.3 there is a new BlockExplodeEvent, make sure your protection plugin is compatible. However, a fixed problem is fine for me :)

Posted Jun 28, 2015@GodsDead It should be saved in the database inside the Cannons folder. Are there any error in the log? What settings did you use? I will try to verify the problem.

Posted Jun 28, 2015Hey DerPavlov I have some demo infinite cannons at my spawn for new players to experience what cannons can do/are, one issue is that they keep resetting to not having a projectile in them, its setup so once a projectile is added they are infinite, I can only assume this happens after a restart, is this information not saved? Or is this a bug/something I have done wrong?
