How do I split a long string into chunks based on the character count?

Hi!

I'm trying to create a dialogue system in which the input text for a dialogue can be any length. The game should then take the input and break it into chunks that can be displayed comfortably on the screen.

How can I break a long string into chunks of say 200 characters while also considering the spaces between words (so that a word doesn't get broken in half)?

len(text) gives you the length of the text

tokecount(text," ") gives you how many words are in the text.

with tokenat(text,index," ") you can get a specific word of the text based on its index

With these you can create a system to do what you want.

To read more about system expressions, check this:

One way is to add a word at a time to the chunk, and measure how big that will make the chunk before adding a word. One possible way:

var dialog = "Four score and seven years ago, our forefathers all ate pizza with pepperoni and pineapple."
var index = 0
var chunk = ""
var word = ""

on function getChunk
-- set chunk to ""
-- while
-- index<tokencount(dialog, " ")
-- -- set word to tokenat(dialog, index, " ")
-- -- compare len(chunk)+len(word)+1<200
-- -- -- set chunk to trim(chunk&" "&word)
-- -- -- add 1 to index
-- -- else
-- -- -- stop loop

Thank you for all the replies!

I will try to implement R0J0hound's suggestion next.
