.. joins pieces of text. Calculate the numeric level first, then use tostring() to put that number into a readable label.
Mira starts at level 3 and earns 2 levels. Return the text Mira | Level 5. The example calculates the new level before joining the label. The checker assesses the returned text.
Interface: Return the composed player display string.
| Input | Expected |
|---|---|
Player information | "Mira | Level 5" |
local level = 3 + 2
return "Level " .. tostring(level)The addition calculates 5; joining text creates Level 5. return gives that complete text to the checker.
New syntax: .., tostring()
Numbers support arithmetic such as +, -, * and /. Text uses .. for concatenation. Joining "Level " and 4 creates text; it does not add a number to a sentence.
tostring converts a value into text intentionally. Some concatenations can coerce numbers, but making the conversion visible helps you distinguish calculation from presentation.
Calculate the result first, then turn it into a readable label. Quoted "12" is text; unquoted 12 is a number.
