While working on my spaceship "cyclone" I decided i wanted to add cannons on to it. Ones that actually function.
Because of this, the progress of the actual ship construction has halted as I've spent the last few days designing a TNT cannon with a friend of mine. And the result is the HAAFC. Three rows of TNT (I believe 8 are detonated per row) blast a single block of TNT out of the barrel at a slight angle. Point of detonation is approximately 190 blocks away at about 5 blocks higher than the firing height. Reload is simple and automated, utilizing a piston-based BUD switch, allowing you to reload the entire cannon in about 12 seconds by placing the TNT into the same spot repetitively.

While I'm otherwise happy with it's current state, I'm afraid I'm going to have to halt spaceship contruction for a little bit longer. turns out that an MCedit-copy-pasted-and-rotated TNT cannon is the buggiest thing since the BF3 beta. Due to the TNT jumping when ignited in a certain direction, the TNT cannons can only point one way (west or north I think), otherwise it becomes unstable and is likely to misfire itself into oblivion. The BUD switch also when copy- pasted will cease to function under any semblance of logic or coherency and even rebuilding it doesn't seem to make it work as intended (even though building a new one somewhere else works fine. 'cause you know. why the f*ck not?). As such, the spaceship will have to be rotated (I can't wait to see what that does to the reactor room circuitry....) and each of the intended 6 HAAFCs will have to be built manually. And since I don't have as much free-time as I'd like, this might take a while (provided I even CAN get the darned things to work consistantly).

Anyway. The cannon can be found in the .rar file. Feel free to do whatever with it
