How can I find another player in Minecraft Pocket Edition? [duplicate]

You'll need the following tools, which should be fine if you're in Creative mode:

• The compass
• The ability to fly
• A bit of patience

If Steve has built something far from the spawn point and Alex wants to find it, Steve will have to do most of the work here. Let's assume that Steve is standing by his work of art, whilst Alex is lost somewhere (having wandered for hours without finding anything).

The key thing to realise is that the compass doesn't point in a fixed direction along an axis of the world, but rather it always points to the initial spawn point.

Steve should start by building a very tall tower somewhere near his base. The easiest way is to start flying near the ground, look straight down, and keep tapping build whilst flying straight up. In a few seconds you'll have a very conspicuous totem pole reaching to the sky.

Now Steve needs to float in the air near the totem pole, facing due South (that is, with the compass needle pointing straight backwards). Steve should then fly backwards (keeping an eye on the compass to ensure he keeps going in the same direction) until the totem pole just starts to fade from view. At that point, he should drop to the ground right where he is and build another sky-high totem pole.

Then, just repeat: fly near the pole, face due South, fly backwards until it starts to fade, build another pole.

Of course, since you are facing South and flying backwards, you're flying due North (i.e. straight towards the spawn point).

Meanwhile, Alex need only follow her compass due North until she reaches the spawn point. Once she arrives, she can give Steve a big hug before they make like Hansel and Gretel and hand-in-hand follow the trail of poles back home.

I used this method (after wasting two hours searching in vain) to find a building that was a 90-second flight away from the spawn point. It took only about 10 minutes. Good luck!
