good morning server.
Me and @NutjobBob decided to make our own shop, as title suggests it is called:

The NutNest contest shop

but what does this shop provide?

as you may know, me and @NutjobBob are two redstone experts, he more than me lets be honest... but let's move on.
the shop provides:

Redstone services

• basic redstone circuits
• advanced redstone circuits
• custom redstone circuits (basically, silly redstone creations on hire)

but I don't want you to get in my base! you'll sureley think
infact I won't get in your base, here are the sharing methods we'll use:

• invite you into a private server
• via video, we'll record a video with krut or VBO, wich are the cheapest and best recorders on the market.
• the video will be sent to you via e-mail

command block help

yes, remember we both aren't the red engeneer, so don't expect us to create a cyborg snake who shoots lazers from the tail or bullshit like that because we are not going to.
service provides:

• basic command block science
• custom intermedial command block creations

shring methods:

• private server
• via sending you a .txt file using an e-mail.

costs depend on the creations, have a good day!

service starts in 4 days

how complex redstone circuits do you offer? @HaloNest @NutjobBob

@HaloNest very very very very high

that doesn't really answer my question

very complex

how about fully automated security system is 10 and a simple invisible door 1 can you give me a number for the most complicated you guys can do? @HaloNest @NutjobBob

10

@HaloNest 10

what is the most complicated you will do and what price?

depends on what people ask

@HaloNest depends on what people ask

hypothetically if i asked you to set up a bunch of deathtraps in and around a large castle with lots of narrow winding corridors, high ceilings and stairs what traps would you lay and how much would it cost

1st i said I won't get into your base
2nd it depends on the castle
3rd cost it depends on how much material I will use

@HaloNest 1st i said I won't get into your base
2nd it depends on the castle
3rd cost it depends on how much material I will use

1 hypothetical base
2 mainly medieval (think towers, spiral staircases and long corridors)
3 as efficient as possible

Thank you!

UPDATE: the shop is free but it is appreciated to leave an offer for our work

@thegoldsmith simple invisible door 1

I made you a 'simple' invisible door. 10 points if you can replicate it :)

here we go!

pardon me, what's a now ball?

jokes apart...

• what kind of entities?
• we are talking about more than one command, but will do

I have found a solution that works relatively well. The main issue is that when a snowball lands, the entity disappears immediately. To counteract this, we can use an armor stand marker to track the last known location of the snowball. This is not exactly where the snowball hits, but close enough for practical purposes.

First, you need to set up a scoreboard objective to track the snowball's lifetime, and another to detect a lonely armorstand.

/scoreboard objectives add snowballTime dummy
/scoreboard objectives add hasSnowball dummy

Now, create a fill clock (or use 1.9's repeat/chain command blocks), and run the following commands:

/scoreboard players add @e[type=Snowball] snowballTime 1

/execute @e[type=Snowball,score_snowballTime=1] ~ ~ ~ summon ArmorStand ~ ~ ~ {NoGravity:1b,CustomName:"SnowballMarker",Marker:1b,Invisible:1b}
/execute @e[type=Snowball,score_snowballTime_min=2] ~ ~ ~ tp @e[type=ArmorStand,name=SnowballMarker,c=1] @e[type=Snowball,r=1]

/scoreboard players set @e[type=ArmorStand,name=SnowballMarker] hasSnowball 0
/execute @e[type=Snowball] ~ ~ ~ scoreboard players set @e[type=ArmorStand,name=SnowballMarker,r=1] hasSnowball 1

/execute @e[type=ArmorStand,name=SnowballMarker,score_hasSnowball=0] ~ ~ ~ summon the entity you want ~ ~ ~ {Fuse:0}
/kill @e[type=ArmorStand,name=SnowballMarker,score_hasSnowball=0]
