My world mining command snowball

1. After 1.8, the command can't use the item ID. to use the English name of the item, the command box is command_ block Here is a list of item IDs and English names in minecraft

2. Try not to use a pick to dig stones. Generally, use a pick to dig diamonds and other things, and your pick is used up again. Although the occurrence rate is small, it is not recommended unless you are a local tyrant. Don't panic when you encounter magma, so that your equipment will be destroyed, including yourself. When mining, it is best to bring a bucket of water and a group of sand or sand to build a bridge. Mining is best not to dig the head of the box and the foot of the box, there may be magma, dig below may fall into the deep mine cave to die. Don't play with mining. If you are mining in a mine, you must have weapons. You should always observe whether there are monsters nearby and their sounds. Even if you detect danger, you can defend yourself or take refuge in a hut

3. You can dig snowballs with a shovel

4. My world doesn't get a snowball command in two seconds? I haven't played this game before, so I don't know.

5. One instruction can't do it, but it can loop
but I'm java1.8. X version, is it possible to be compatible<
/ scoreboard objects add snowball stat.useitem.snowball/stat.useitem.332
build a scoreboard called snowball and use a snowball club to add points
cycle (first level) - & gt; give @a[score_ snowball_ Min = 1] snooball
loop (at least a moment slower than the previous one, but not too slow) - & gt/ scoreboard players set @a snowball 0

6. This plug-in, if you are playing in the server. Then a single person is not allowed. Because it is a plug-in

7. Create variable time:

/ scoreboard objects add time mmy
first! We need to prepare a high-frequency red stone (I x, also high-frequency red stone)...... Connect a command box, the content:
execute @ E [type = snowball, score]_ Time_ min=5] ~ ~ ~
kill @e[r=1,type=! Snowball]
means to let the snowball kill the entity within one grid all the time. Some people will ask: & quot; Why add a score_ Time_ What about min = 5? Is it OK if you don't add it& quot; Then I can only say that you forgot a big event, you are also within @ e! The snowball you throw may kill you
therefore, we need to connect the high frequency red stone with another command box:
scoreboard players add @ E [type = snowball] time 1
in this way, the time value of the snowball will increase all the time until it is thrown to the ground. When time is greater than 5, almost the snowball has left you, and it will not hurt you any more. The last step is to get rid of the snowball. We use high frequency Redstone to connect a command box:
execute @ E [type =! Snowball] ~ ~ ~ ~ kill
@ E [type = snowball, r = 1]
turn.
