Engine and cannon by: dragonpie646

the engine is a redstone device. It acts like a superpowered piston, that extends to all sides and can be controlled by attaching joystick (pretty much self-explanatory.) You can change the number of pistons and which one's push at a time, or you can set some of them to sticky pistons. This engine can be very fast or slow depending on what you choose. There is a downside, however. When any of the blocks connected to the engine break half of them explode and the rest catch on fire and fall. If you are wondering what this would be used for, I think it would be used for things like piston tanks and airplanes. This would make Minecraft warfare much more realistic, entertaining, and fun. Cannons are of course, weapons. You can attach a cannon to a plane or tank and fire it. You can load TNT, anvils, dripstone, or whatever Mojang comes up with next. The cannon, when hit, explodes, whatever it contained will be thrown everywhere. These changes to Minecraft would still keep it what we know and love, while also making it more realistic.
