So...  I thought of a cool idea for the Xplosives mod. A cannon that will shoot explosives, much like the hand cannon, except this would be placed down like a block. It could be crafted in the same way as the hand cannon, except the two gaps would be filled by wooden planks. when you place it down, you can then right click it and get a GUI to put in the Xplosives, and mabey set the y-axis rotation. Then, you can set it off using a detonator or a redstone signal, and either of these will cause it to shoot I just one of the Xplosives from inside the cannon. Hope you think this is a cool idea!
