I want to create a new type of TNT which always faces in the direction the player looks at when placing it.
When provided with a redstone signal, the fuse should be about 3 seconds long, then it should create a tunnel in front of it which is 15 blocks long and 3x3 blocks in size.
It also shouldn't fall to the ground when lit.
So basically a mining machine with a little bit of BOOM! :3
I would appreciate any kind of help.
