First of all, let's talk about the common nature of Gray technology ore:

① Do not support time luck;

② It has nothing to do with ecological community.

Gray technology has two types of mineral production: small ore, and mineral veins

Barren ore

The barren ore can be generated in the world, hell, end, and all Gray technology support.They are messy, and their mining levels are one level lower than the original ore, so when they cannot dig at certain ore, they generally choose to find barren ore.Broken these ore, a crushed ore, a miscellaneous powder, a gem, a stone powder/a miscellaneous stone powder may be dropped.But barren ore cannot be obtained through precise collection.

Although GT has thousands of reserves, there are still some useful in the barren ore, such as barren diamond ore (no graphite ore is found, it doesn't matter, barren ore helps you!), Barren redstone oreAnd need to make a murder?

Vein

The ore vein only generates only one in a large block of every 3x3 block, and it is possible that the size from 16X16X5 to 80X80X8.A maximum of 4 different ores are generated in a ore vein, but the number of ore is tens of thousands, and the gap between them is small.However, the ore will only generate stones, red/black granite, hell rocks, or end -ground stones that can be replaced with corresponding ore.Therefore, there is no mineral vein in a certain block, but there is no replaceable block.

Mine veins consist of four parts: upper ore, lower ore, middle ore and sporadic ore.The upper layers of the upper part of the ore vein generate the upper layer of ore, and the middle layer of the middle layer is generated in the middle 2 to 4 layers, and the lower layer of ore is generated in the 2 to 4 layers below; the sporadic ore is randomly generated in the ore vein.The most densely generated ore in the heart, and there are fewer edges.

After that, the players are most desired: find the vein.To find the vein, we must first know how Gray Technology generates when generating the world.

Gray Technology first generates the MC, a new world photo block, and is divided into one large block every 3*3 blocks, as shown in the figure below.The yellow grid is the center of the large block.

Then Grey Technology's generator began to generate ore veins.First of all, the generator of Gray Technology draws the vein first. For example, the generator of Gray Technology draws a sulfur vein, but the sulfur vein is only generated in the lower bound, so it cannot be generated, so it will be drawn again.The height, and the height of the ore vein is 40 ~ 50, the generator of Gray technology selects the height of 48. Finally, a ore vein is generated at the position of the height 48 in this position.

But how to find the Mineral Pulse Center, this requires the formula, the formula is as follows.

M and n are arbitrary natural numbers.The coordinates are (x, z).

Some people may not be as blind as I said. According to the tutorial of Marco, the outer side of the mine vein is placed to determine the central block, and then a hole in every two blocks.But this method has a defect -that is, the generator of Gray Technology will change the ore vein coordinate formula when the coordinate span -limited time.This is a bug.So obediently calculate the coordinates of the formula.

Note: In the 5.09.29 version, the problem that the cross -phenomenon formula will be changed, and the formula has been changed to (24+48m, 24+48N) and M and N∈z.

Because the coordinates are troublesome.So I recommend a mine vein coordinate calculator: http://tieba.baidu.com/p/4822052436.
