Using the Single Player Commands mod, you can type "/noclip" (without quotes) and you will enter a state where you can fly around and also walk through solid objects you normally wouldn't be able to.
no
You have to download the mod from minecraft to get the lucky blocks. Then the lucky blocks will spawn randomly across the surface.
Yes, try searching Minecraft Little blocks Mod
There are no quarry blocks in Minecraft. Those are added by Buildcraft, a mod.
if your thinking of little blocks mod. you need the Gulliver mod. (makes you small)
Minecraft is like an IPad. "There's a Mod for that" :3 you can try the Gulliver mod where you can make yourself bigger or smaller. and there's the Shape Shifter mod where you can become an Enderman which is 3 blocks tall and you will have the ability to teleport. Remember there is a Mod for Everything so if these mods don't sound good to you I am sure you will find something better :3
Most mods are free, so chances are you shouldn't. Just download the mod and follow the instructions to implement it into Minecraft.
i dont kno if u can change the blocks
Need Soul sand and clay blocks. Put the Soul sand on top the clay blocks
only if you have this mod that gives you blocks like the mob spawner or what you want a nether portal
You do not need to mod it, all you have to do is place obsidian blocks like this [][][][] []////[] []////[] []////[] [][][][] []=obsidian /=empty space and then use a flint/steel to light the middle and BOOM there you have it
Nope. You HAVE to download a minecraft mod to have it.
