How to Detect Players in Water in Minecraft (Command Block)
Minecraft Java Edition 1.21+ and 26+ β Scoreboard Timer + Execute if Block Water Tutorial
In this tutorial, you will learn how to detect when a player is inside water in Minecraft using command blocks.
This system works in Minecraft Java Edition 1.21+ and 26+ and uses a scoreboard timer to count how long the player stays in water.
With this method, you can run commands after a specific time, such as dealing damage, teleporting, giving effects, or activating functions for adventure maps, minigames, and custom servers.
To start, let's create this scoreboard that will track the time spent in water
scoreboard objectives add time_in_water dummy
If you want to see how long the player has been in water, you can use this command
scoreboard objectives setdisplay sidebar time_in_water
Every 20 points in the scoreboard equals 1 second in water, meaning a value of 60 equals 3 seconds, and so on
Now we need to detect when the player is in water and start counting
To do this, place the following command in a Repeat command block set to Always Active
execute as @a at @s run execute if block ~ ~ ~ water run scoreboard players add @s time_in_water 1
The command below will execute a function after the player stays in water for more than 3 seconds
execute as @a if entity @s[scores={time_in_water=90..}] run function comandos:time_in_water
The function will reset the timer and apply damage to the player
You can replace it with another command after run
