Hey, it's me again :)

After a very long break, I've started on my textbox engine again, and wrapping won't work.

//These are the font and background images.

int font = LoadFont("font1.png");

int box = LoadImage("box.png");



int vborder = 5; //The vertical and horizontal borders.

int hborder = 5;

int linespacing = FontHeight(font) * 2; //The spacing between lines.



void Textbox(string text, int x, int y)

{

	int speed = 2; //This is how long it waits between letters.

	int i = 0;

	Blit(x, y, box, screen);

	int origx = x;

	int origy = y;

	y += vborder;

	x += hborder;

	int linenum = 1;

	int another = 0;

	int wordlen = 0;

	int wordstart;

	

	while (i < len(text)) //Loop through the text, blitting it letter by letter

	{

		if (strcmp(mid(text, i, 2), "\n") == 0) //Go to the next line if we encounter a \n

		{

			i += 2;

			y += linespacing;

			x = origx + hborder;

		}

		

		if (strcmp(mid(text, i, 1), " ") != 0 && strcmp(mid(text, i - 1, 1), " ") == 0)

		{			

			wordstart = i;

			

			while(strcmp(mid(text, wordstart + wordlen, 1), " ") != 0)

			{

				wordlen += 1;

			}

			

			if (x + TextWidth(font, mid(text, wordstart, wordlen)) > origx + ImageWidth(box) - hborder)

			{

				y += FontHeight(font) * 2;

				x = origx + hborder;

			}

			

			wordlen = 0;

		}

		

		PrintString(x, y, screen, font, mid(text, i, 1));

		ShowPage();

		x += TextWidth(font, mid(text, i, 1));

		i++;

		

		if (b1) //Go to the end if the button is pressed

			speed = 0;

		Unpress(b1);

		

		Wait(speed);

		ShowPage();

	}

	

	while (!b1 && !another)

		UpdateControls();

	

	Unpress(b1);

}



void Wait(int delay)

{

	int timestamp = systemtime;

	while (systemtime - timestamp < delay)

	{

		UpdateControls();

	}



}

There's the source. It's just not wrapping at all. Thanks in advance to anyone who can help me.

EDIT: Read the last post.

Secondly, why aren't you using the builtin WrapText function to pre-wrap your text! Then you don't need a slow loop with lots of function calls on strings in VC. :D

You can get around the problem of it disappearing and appearing on the next line by just ordering your wrap correctly. Instead of:

string toprint = "...";

string chunk = "";

int pos = 0;

int wrapwidth = 150; // or whatever

int font = default_font; // or whatever



while (pos < len(toprint))

{

   pos++;

   chunk = mid(toprint,0,pos);

   printString(0,0,screen,font,wrapText(font,chunk,wrapwidth));

}

instead use...

string toprint = "...";

string chunk = "";

int pos = 0;

int wrapwidth = 150; // or whatever

int font = default_font; // or whatever



toprint = wrapText(font,toprint,wrapwidth); // wrap it HERE instead



while (pos < len(toprint))

{

   pos++;

   chunk = mid(toprint,0,pos);

   printString(0,0,screen,font,chunk); // and don't wrap here

}

Does that make any sense? (Also I'm not certain this code runs exactly as written; it's been a while since I've written any VergeC. Hopefully you can get the idea though.)

Hooray!

Oh, and just for sake of reference, people should check out the textbox system that's included with Molasses Meow (and was originally designed for the remake of Rubbish Rogue).

You can customize the box colors (and shading style -- it doesn't need to be solid colors even though that's how I made the settings in Molasses Meow), the font, how the textbox handles overflow, the position, and other things.

All you should need to do to include the stuff is:

#include "graphics.vc"

#include "textbox.vc"

The only other setup required is as follows:

Make an global int variable called "font_main" somewhere that you set to whatever font handle your textbox uses.

And put the following line in your system.vc's autoexec:

DefaultTextBox();

Enjoy!
