/worldborder and randomTickspeed

Finally! A new snapshot is here and comes along with some awesome changes when it comes to your minecraft world.

/worldborder
Till this snapshot, the world border was an invisible "wall" 30 million blocks away from x=0 and z=0. Beyond this wall the normal minecraft physics (yes, there is some physics in minecraft) are no more and your game will lag more and more until you leave this area.

But now we can finally decide on our own how big our world is (still not larger than a radius of 30 million blocks though)! You can set the center of this world border with /worldborder center (x) (z) (this will not change the coordinates of your world or the worldspawn) and after that you can set the size with /worldborder set (value) (the border will be a box, not a sphere). You can also do /worldborder set (value) (value) which will set the worldborder to the new size within the given amount of seconds (the worldborder will move towards this new value).

You can also set the amount of damage and the buffer (the amount fofblocks you can go outside the worldborder without taking damage, default is 0.2) with /worldborder damage amount (value) and /worldborder damage buffer (value). The damage is per second per block outside the worldborder.

If you want to warn players that the worldborder is close, you can do either /worldborder warning distance (amount of blocks) or /worldborder warning time (time in seconds), which will make the players screen turn red around the edges when the worldborder is within that range. The last one will work best for a moving worldborder.

There are still some bugs when it comes to interacting with the world beyond the border, but this new option is great for mapmaking.

randomTickspeed
A new gamerule is here! And this time you can give a value to it, instead of setting it to either true or false. So with /gamerule randomTickspeed (value) you can now set how fast the game will send out a random tick.

This sounds really cool of course, but what does it do? Well, things like growing crops and trees determine on a random tick the game sends out randomly every so often. If you set the randomTickspeed to a greater value, you will speed up this proces. So crops will grow faster, redstone ore will unlit faster, etc.

It's really fun to mess around with, just remember that the default randomTickspeed is 3 and that a large value will lag your game.

Thanks for reading! I hope you learned something new or maybe even got some inspiration.
