Code Request Post

Hello. I am just wondering if someone could reply to me with a tunnel code for turtles but when they mine and reveal lava, they cover it up with cobblestone or dirt so players can get by, Thanks!

Split into new topic. Moved to General.

If I understood you correctly then that's what you wanted:
I wrote [crappy] code for a turtle that digs a straight tunnel and places blocks underneath (making a bridge) so a player just have to follow the turtle. That turtle was made to travel through Nether: http://pastebin.com/HVbBpEuM (make sure turtle's inventory is full with blocks and if it has enough fuel)
