Cannon Tool!

NOTE: I am no longer able to support this addon due to not having enough time. As such, I will no longer be able to add new features or fix bugs caused by new versions of the game. If someone else wants to take over this mod, they are welcome to message me. Sorry guys.

A tool that allows you to create usable cannons and cannon ammo.

To use, choose the Cannons! tool from the tools list, then spawn a cannon by left clicking. You can spawn ammo by right clicking with the tool. To load the cannon, move any cannon ammo to the loading end of the cannon, which can be changed to the front or rear in the tool settings. It will load after a few seconds, and the cannon will be ready to fire. To fire the cannon, simply press the use key on it (normally bound to E).

There are 4 different types of ammo that can be loaded into the cannon; round shot, which is a solid round ball, canister shot, which acts like a shotgun load and fires many small shots, explosive shot, which explodes upon impact and does damage to anything in its radius, and incendiary shot, which explodes upon impact and sets fire to anything in its radius. Ammo can either be spawned with the tool or spawned from the entities tab in the "Cannon Ammo" section

There are 6 commands for servers that can be used with this addon;

sbox_cannons_adminonly 0-1: This sets whether the cannons are spawnable by admins only. Default 0.
sbox_maxcannons #: This sets the maximum amount of cannons that can be spawned. Default 5.
sbox_maxroundshot #: Same as above, only for round shot. Default 20.
sbox_maxcanistershot #: Same as above, only for canister shot. Default 5.
sbox_maxexplosiveshot #: Same as above, only for explosive shot. Default 5.
sbox_maxincendiaryshot #: Same as above, only for incendiary shot. Default 5.

Check this disscussion thread for updates as they are released. I will post a summary to the thread every time I update the addon.

Please let me know immediately of any bugs you find so I can fix them. If you are having problems with a cannon in a dupe, make sure to update the cannon by left clicking it with the cannon tool selected in order to update its settings before submitting it as a bug. Feature suggestions are also welcome.
