Hi^^
I'm trying to count how many occurrences of a character (especially punctuation) are in a string.
I tried with this:

Code:
$gameVariables.setValue(243, ($gameVariables.value(267).match(/,/g) || []).length)

If I insert in the string(267) a "," or a "!" it seems to work and var(243) returns 1 occurrence.

But if var(267) = "test text?" and I use match(/?/g), then var(243) returns 0.
With other punctuation it returns even stanger numbers...
For example if I try to count how many "." or "..." are in a string it returns respectively 14 and 5 even if I put only 1 of them in the string...
It's clear I'm missing something but I can't understand what :kaocry:

Regular expressions have a number of special characters, including ? and .. If you want to check for those specific characters then you will need to \escape them. E.g.
  • ? -> "Hello? Is anyone there??".match(/\?/g).length
  • . -> "Who. Cast. That. Slow. Spell. On. Me?!".match(/\./g).length
  • ... -> "What an...uh...interesting idea.".match(/\.{3}/g).length

I might not participate in the Boss Battle contest after all... I have more important things to do, like Wishful Wanda. And of course the Dark Deception spinoff I plan to pitch, Demon Slayer.
