Bukkit

@robotnikthingy That was not that motivation I had in mind, but it works too.

Your problem sounds like 'autoaim'. So basically it cycles through entities next to the cannon and fires. The first approximation would be 'line of sight'. It is easy to implement, but if the projectiles is slow it will not work. Additionally I can correct the z-angle with the distance - this is kind of experimental at the moment.

If you want to change the angle of a gun, you have to select it somehow. So you need the location of the gun (not very practical in a command), the name of the cannon, or the name of a group of cannons. For you the last would be the best, I think. So you select all cannons in the castle, aim at a spot or a entity, and wait for the impact.

@robotnikthingy At the moment the cannon can only be turned by clicking it. No commands, no autoaiming. What you mention sound like an interface to other plugins, so other plugins can change the properties of a cannon. This is on my list, but I have to admit I have no time at the moment.

If you tell me what you have planned, maybe we can find an easy solution for this. Also a basic autoaim can be done in a few hours. I only need much motivation to start programming :D

@willkiller1234 A redstone torch will not work with cannons. You need a normal torch on top. For redstone firing you need torch underneath the barrel. I think this is your problem if I understood you correctly.

It is planed to make custom cannon designs possible in the future, but I hadn't had time to implement it. Basically you build a cannon and mark all block. The plugin makes a .yml file for this cannon an you can edit the properties, like usable projectiles, maximum gunpowder and all the stuff. So a wood cannon may fire only 10m while a diamond barrel can fire all over the map. I have to get this teleport working. At the moment the snowball stops midair after 150 blocks :D

@willkiller1234 No it is player based. You give the player the permission to use a cannon. Best you write a small plugin that sets permissions if the player joins or leaves a faction.

@robotnikthingy Cannons can be fired by redstone. Wire the button on the back with redstone or place a redstone torch underneath the barrel. In 1.9.4 the angle is also saved in the database. In combination with the redstone autoreload (chest with ammo on the last block of the cannon) you can set up a cannon that fires if triggered and reloads. So firing at the same spot is no problem, but there is no autoaim or something (have thought about that, but had not had enough time to implement it).

I also know that cannons is really bad documented, so if anyone is interested in writing a small tutorial, contact me.

@komunx3 Ok, than open your config.

• Search for projectiles and add there -leather (the name does not matter)
• Then copy the cobblestone entry below and name it leather (the same name like in the list)
• edit die projectile ID, data and projectile properties.

leather:
  name: leather
  id: 334
  data: 0
  player damage: 7
  max speed: 3
  cannonball:
    cannonball: true
    explosion power: 2
    penetration: 1
    timefuse: 0
  canistershot:
    canister shot: false
    spread: 0
    amount of bullets: 0
  placeBlock:
    enabled: false
    radius: 0
    amount: 0
    materialID: 0
    materialData: 0

    effect duration: 5
    super breaker: false
    incendiary: false
    blindness: false
    poison: false
    slowness: false
    slowDigging: false
    weakness: false
    confusion: false
    hunger: false
    teleport to impact: false

@komunx3 But gunpowder and cobblestone is working? I have never tested Leather - but it should work if you add it as projectile in the config. You have to add it twice, as projectile in the list, so you can load it, and as projectile properties.

@DerpyZ I made a small link in the description. Is there any audio in you version?

@komunx3 Ok, thats odd. You should get at least an error at startup or a message in game. Do you use the R1.0 or the development build of bukkit? You can send me also your plugin folder, then I am going to test it.

@komunx3 Give me more info

• You are using the beta now?
• Which bukkit version?
• Any errors or something?
• Does the game say, "you have no permission to load the cannon"?
