Conditions and loops

Conditions

if {@sender -> team} is "SCPs"
    Reply "SCPs cannot use this command"
    stop
elif {@sender -> health} < 50
    Reply "You are badly injured"
else
    Reply "You may continue"
end

Common comparisons are is, isnt, ==, !=, >, <, >=, and <=. Combine them with and or or. ! and not are not condition operators in SER.

stop ends the current script immediately.

Chance

Use the returning method inside a larger condition:

if {Chance 25%}
    Print "The roll succeeded"
end

Use the statement for a standalone branch:

chance 25%
    Print "The roll succeeded"
else
    Print "The roll failed"
end

Fixed repetition

repeat 3 with $iteration
    Print "Iteration {$iteration}"
end

Conditional loop

$count = 0
while $count < 3
    $count = $count + 1
    Print $count
end

Iterate over players or collections

over @alivePlayers with @player
    Hint @player 2s "Hello {@player -> name}"
end

Choose the loop variable prefix to match each element.

Long-running loop

forever
    wait 1m
    Print "One minute passed"
end

Every forever loop must eventually yield using wait, wait_until, or a yielding method. Otherwise it can monopolize the server thread.

Use continue to skip the rest of one iteration and break to leave the nearest loop.

Next: collections.
