Waiting for things is tedious, is there any way to speed up the passage of time?
I'm making a creative map that uses a lot of vines. Waiting for these to grow naturally is taking a long time, and placing them manually would be a huge amount of effort. Is there anyway to expedite the natural growth of the vines?
The growth of vines (and other random stuff) is controlled by the so called random ticks, which is part of the regular block ticks
On every game tick, 3 block positions are chosen at random from each section in an area 15 chunks on a side and centered on the player. Any blocks at those positions are given a "random block tick". Most blocks ignore this tick, but some use it to do something spontaneous: plants grow or die, fire burns out, ice melts, leaves decay, farmland becomes hydrated, and so on. These ticks are called random ticks.
As of snapshot 14w17a or release version 1.8, the number of randomly chosen blocks per game tick can be set using a game rule:
/gamerule randomTickSpeed [value]
The default value is 3. It can also be set to 0, which means that nothing in the world will ever grow, which can be quite convenient for adventure maps or minigames.
