Problems with string:match()

Help and Feedback Scripting Support

Why does this work:

local str =  "Apple13"
print(str:match("Apple1"))

Output data: “Apple1”

But this doesn’t

local str =  "Apple-1-3"
print(str:match("Apple-1"))

Output data: nil

Because ‘-’ is a special character and must be escaped with ‘%’ if you want to match the actual character.

To match a ‘-’, try print( ("Apple-1-3"):match("Apple%-1") )
