Well ive been at this for 2 days and im close to giving up I need a function setup like this..

FUNCTION WORDWRAP(message$,startX,startY,maxCharX,maxLineY)

ENDFUNCTION messageleft$

where I can specify a message, itll print the message using wordwrap, never going over the maxCharX limit and hard returning to the next line until MaxLineY is reached, and will return the remaining text.. If all the text is used then it returns nothing. Thank you so much whoever knows how to do it

(I can't even find a good tut on this!!)

There's a supprising lack of information on this ... I'm not sure why, it's quite a difficult thing to get your head 'round.

I've been working on a little function on and off for several weeks now for my MUD. I'll post up the function and contact you ASAP (soon as I finish it that is ).

Not sure what the actual problem is but you may want to forget about Numbers of characters as such and check for the width of each character. It will depend on the font used to how many characters will fit in your text area.

no actually, number of characters is fine for what I'm doing Width is fine too, it would be easy to convert it either way.. The function needs to take the text, print it on screen and wrap the words to a new line when the maximum amount of characters per line is reached.. and it needs to wrap it when it hits a space " " not in the middle of a word.

I have a wordwrap solution, but it's structured much more simply. You define a rectangular area of the screen and it wraps within that automatically and scrolls up when it gets to the bottom. Get it here: http://www.stevetiffany.com/darkbasic.html

Geez people, just insert a line feed character [chr$(10)] when you need a new line and count the number of inserts to determine your max lines. Works just fine for the PRINT statement.

Steverino X and jasuk70 have the right idea though. Use the TEXT WIDTH command to find the real width of the characters based on the current font type and size.

ok...this is what I have so far, and I'm simply not understanding why this won't work properly....


the code will not wrap the words at the proper positions..
PRINTB(msg$,x,y) is a function that will print the letters, this part of the program works perfectly, ive tested it, and it even works in this function perfectly.

Here's something that works, although it doesn't limit the amount of lines.

doesnt work when I convert it to the library...

please don't pop this library into your programs yet, because its completely unfinished and won't work without a bit of work yet

and please don't tell me how using sprites/etc. is better, though I do value your opinions and such, I've already been in this discussion more than 3 times

PRINTB() works similar to the text functions, so I thought converting these sources would be easy, but for some reason it never works.. please help
