This is a mod adds artilleries in your Minecraft.
Crafting

This MOD's crafting system is complicated. See this image.
1.Cannon
First, make a basic Barrel with six Iron Ingots.You can expand its caliber(50~300,6 stages)by crafting them lengthways, and make its length(100~1600,16 stages) longer lining them.
Then, craft a Barrel with a Cauldron to make a Cannon.
Optionally, you can craft an auto loader with them.
2.Chassis
First, make Tracks with a Iron Block and eight Iron Bars.
Next, make a Carriage with three Iron Pressure Plates(Weighted Pressure Plate) and two Iron Ingots. You can craft improved ones. They can turn the cannons faster.
Then, make a Chassis with a Carriage and two Tracks.
Optionally, you can craft an Engine , and craft with a Carriage and two Tracks when you make a Chassis.
3.Artillery
Finally, craft a Cannon and a Chassis to make an Artillery.
4.Options
You can make your arty harder crafting them with armor plates.
You also can paint it camouflage crafting it with specific 8 items.
Performance

This is the relation between the barrel and the performance.
Greater carriage enable your arty to move its barrel faster, but NOT itself.
Greater engine enable your arty to move faster, but NOT its barrel.
Thicker armor enable your arty to protect small ,slow entity's attack, but make it slower.
Any camouflage do NOT effect to its performance.
How to use
Completed crafting? Now place it and right-click to ride on.
Press R key to open a GUI to reload ammo, gunpowder and fuel ,and watch information of your arty.

Right-click riding the arty to shoot. You can shoot ANY BLOCKS , and ANY ITEMS (Entities) which are able to be ejected by dispensers , including MOD-added items.
ex) TNT Arrows Firecharge Creeper(Using mob eggs) Lava(Using lava in a bucket) Stone Fence BambooSpear(by BambooMod) Shells(by ShellMod) and other...
I recommend to use my ShellMOD (-> http://minecraft.curseforge.com/projects/shells-mod) with this. Of course, you can shoot shells with arty!!
Dependencies
Minecraft Forge needed.

Issues
-Vanilla recipe book sucks
-Blocks ejected sometimes disappear; Shooting diamond blocks is not recommended.
Further updates (maybe)
-Add stationary cannon
-Make more cool model
-Multi-barrel cannon (will look like massive mini-gun!)
