I've been trying to get together a per player spawn setting mechanism and currently stuck on storing a position and player UUID together in a way where it's easily queryable and thus teleportable.
This is what i've tried so far:
/data modify entity 6f88f8eb-cfa3-44bf-a621-52b3e7d753e7 Pos set from storage game:player Spawn{target:'[{"selector":"@p"}]'}.location That selector block is what isn't working. I need a way to get a selector working in that nbt search part. if that's impossible something that drives the same functionality. Also using a temp data storage would be acceptable if it's passable into that target based query :)
Storage game:player has the following contents: { Spawn:[ { location: [-39.89557466099629d, 66.0d, 42.25176377238329d], target: [I; -1155610777, -758824872, -1437747869, 728530035] } ] } 1 Answer
The way I solved this is, I copied the list of spawns to a new location. Then I iterated through them by copying the item in location 0 of the list to a temporary spot named Current, then removing it from the list so that the next iteration can get a new item.
# list_find.mcfunction -- # Set current to null to check if list is empty in the next step data modify storage tools:iteration Current set value {} # Set current to first item in list and check if it was successfull. if not loop wil exit if it hits iteration_continue. execute store success storage tools:iteration IterationSuccess int 1 run data modify storage tools:iteration Current set from storage tools:iteration List[0] # Remove currently processed item from list. data remove storage tools:iteration List[0] # Lists should always come as [Indexer, Item] pair lists data modify storage tools:compare A set from storage tools:iteration Current.Indexer function tools:compare # If list item is what we're searching for. run exit loop procedures. execute if data storage tools:compare Success run function tools:iteration_exit #if not continue iteration (until list is empty) execute unless data storage tools:compare Success run function tools:iteration_continue #iteration_exit.mcfunction -- data modify storage tools:iteration Result set from storage tools:iteration Current.Item #tellraw @a [{"text":"iteration result: "},{"storage":"tools:iteration","nbt":"Result"}] #iteration_continue.mcfunction -- #if list isn't empty run iterate again execute if data storage tools:iteration IterationSuccess run function tools:list_find #tellraw @a [{"text":"iter success: "},{"storage":"tools:iteration","nbt":"IterationSuccess"}] Now, I just compare the Current.Indexer and the player UUID by writing over current with /data modify. However, because we need the current values later, we must store Current.Indexer in a temporary storage.
If they're different, /data modify returns 1. If they're the same, /data modify returns 0. Then, reverse the result with a scoreboard for later ease of use.
#compare.mcfunction -- #used by a vscode plugin for auto completion #define storage tools:compare # tellraw @a [{"text":"Compared: "},{"storage":"tools:compare","nbt":"A"},{"text":" and "},{"storage":"tools:compare","nbt":"B"}] # If an overwrite happens, a 1 will be stored in Global(fake player)'s CTemp score. If values are the same, a 0 will be stored. execute store success score CompFail Tools run data modify storage tools:compare A set from storage tools:compare B # Reverse and set to storage tools:compare success execute if score CompFail Tools matches 0 run data modify storage tools:compare Success set value 1 execute if score CompFail Tools matches 1 run data modify storage tools:compare Success set value 0 #tellraw @a [{"text":"A == B: "},{"storage":"tools:compare","nbt":"Success"}] If the comparison returns true, we can exit the loop and use the Current.Indexer to teleport a tagged armor stand to the location. aka we data modify the armor stand Pos to Current.Item. and then tp player -> tagged armor stand
#spawn.mcfunction -- #prepare to find from spawns and get spawning player's coordinate. data modify storage tools:compare B set from storage player:spawning ID data modify storage tools:iteration List set from storage player:spawns List function tools:list_find data modify entity @e[tag=TPTarget,limit=1,sort=nearest] Pos set from storage tools:iteration Result
