I have an interesting idea for a mod but i have no idea how to do any coding whatsoever. plus it's a mac so i doubt many people have tutorials on coding. anyway my idea is to create a time machine. the crafting recipe for it would be:
O= Obsidian G= Glowstone C= Clock D= Diamonds I= Iron Ingot R= Redstone Dust

OGO
CRC
DID

it is an item, not a block and if you right click while holding it, it asks you what time that day you want to go to (possibly day if possible) it has a durability of 1 use and whatever time you chose, it takes you to wherever you were at that time holding whatever you had in your inventory with any blocks broken or placed reversed. so it's like a reset button for that day. Could anyone create this? (modloader may be needed)
