The string in question appears when using the /attribute and /spectate commands. However, it only works with the following selectors: (https://crowdin.com/editor/minecraft/10038/enus-ptbr?view=comfortable#5341538)
. @p (player executing the command)
. @n (nearest entity, which is the player themselves if alone, or another nearby player)
. @r (random player)
. @s (entity or player executing the command)
It does not work with other selectors, such as:
. @a (all players)
. @e (choose entity type) - for example, @e[type=minecraft:slime].
Notice that more than one player was not mentioned, only a single player executing the command. I tested it on other creatures/entities, but it was only executed on one player at a time, making the original string "[...] the provided selector allows more than one" not very logical. Additionally, it did not work on creatures.
Original string:”Only one player is allowed, but the provided selector allows more than one.”
Correction:”The execution of the selector allows one or more players.” or “The selector used allows one or more players.“
I don’t understand the problem. Please provide steps to reproduce and describe what you expected to see and what you actually saw.
