Minecraft – How to make a command block summon an end crystal on top of said command block in Minecraft 1.14.1

minecraft-commandsminecraft-java-edition

I want to put a command into a command block that will spawn an invulnerable end crystal directly on top of the command block relative to the command block's location in world.

This is the current command I am putting in the command block minus any tag for offset since the offset is what I am trying to figure out.

/summon minecraft:end_crystal ~ ~1 ~ {PersistenceRequired:1b,Attributes:[{Name:"generic.knockbackResistance",Base:1f}],Invulnerable:1}

Specific question: How do I put an offset in the command block command in order to get my desired result above?

It seems to me like you've answered yourself, as you already have an "offset" in the command (the ~ ~1 ~ part).

If the question is towards the base of the end crystal being inside the command block, that's just because of it's unusually sized hitbox and texture. To fix this I made the command block summon the end crystal 0.5 blocks higher up, and the output was this:

Either way, the command you supplied works perfectly fine in 1.14.1.

The coordinates can be added as target selector arguments, i.e. inside the @e[...], using the x, y, and z arguments, combined with r to set a maximum radius. Note that Tilde notation is not allowed for this, you need the absolute coordinates.

Placing an enchanted item in an Item Frame has to be done all at once, since the entitydata is running on the Item Frame, not on the item that is in it. This is done by setting the Item tag of the item frame to a valid compound NBT structure for an item, such as

{id:"minecraft:stone_sword",tag:{ench:[{id:16,lvl:1}]}}

for a Sharpness I Stone Sword.

Overall, the command you want to be running might look like:

entitydata @e[type=ItemFrame,x=1,y=2,z=3,r=2] {Item:{id:"minecraft:stone_sword",tag:{ench:[{id:16,lvl:1}]}}}

Be careful regarding the closing parentheses.

You can use the /stats or check the CommandStats datatag of the ArmorStand. I highly recommend use of the /stats command.

Extract the result:

Run these commands once
Note: Anything suffixed with a "_v" can be whatever you want, as long as they're consistent.

/scoreboard objectives add SuccessCount_v dummy
/stats entity @e[type=ArmorStand,name=Lexer] set SuccessCount @e[type=ArmorStand,name=Lexer] SuccessCount_v

This will store the SuccessCount (in case of this command, 0 or 1) in the scoreboard as @e[type=ArmorStand,name=Lexer] SuccessCount_v, which you can then test and use as you would any other scoreboard value.

Add results together:

I'm not going to go into detail here, since I am unsure exactly you want to add together. I will, however link you to a wiki page where you can find the format of /scoreboard players operation <selector> <objective> <operator> <selector2> <objective2>, the only method for doing math in command blocks. (Yes, there is a command dedicated to it. It is not impossible.)

Hope this helps and wish you luck!
