Execute run

Any execute ... run command can be followed by a Block to create a new function that gets called by execute command.

execute ... run {
    <...>
}

Examples

Conditional Execution

execute if score @s appleCount matches 1 run {
    say I have 1 apple!
}

Execute If / Else

Any execute run block can be turned into an execute if / else block by appending an else execute ... run or else run block to it

execute ... run {
    <...>
} else execute ... run {
    <...>
} else run {
    <...>
}

Examples

Multi-Conditional Execution

execute if score @s appleCount matches ..0 run {
    say I have no apples!
} else execute if score @s appleCount matches 1 run {
    say I have 1 apple!
} else run {
    say I have more than 1 apple!
}

Execute If / Unless Function

You can embed a Block in the if/unless function execute sub-command.

execute <if|unless> function {
    <...>
} run <...>

Examples

If Function

An OR condition using if function

example.mcb

function a {
    execute if function {
        execute if score @s test matches 1 run return 1
        execute if score @s test matches 5 run return 1
        execute if score @s test matches 10 run return 1
        return 0
    } run say "Hello World!"
}

example:a.mcfunction

execute if function example:zzz/b run say "Hello World!"

example:zzz/b.mcfunction

execute if score @s test matches 1 run return 1
execute if score @s test matches 5 run return 1
execute if score @s test matches 10 run return 1
return 0
