I'm using this function to draw wrapped text to the screen:

+ Code Snippet

void WrapText( char Text[256], int x, int y, int Width )
{
	int CurrentChar = 0;
	int CursorX = x;
	int LineChar = 0;
	char Line[256];

	while ( CurrentChar < strlen( Text ) )
	{
		while ( CursorX < x + Width || Text[CurrentChar] != ' ' && CurrentChar < 256 )
		{
			Line[LineChar] = Text[CurrentChar];
			CurrentChar += 1;
			LineChar += 1;
			CursorX += 5;
		}
		dbText( x, y, Line );
		LineChar = 0;
		CursorX = x;
		y += 15;
		for ( int i = 0; i < 256; i++ )
			Line[i] = ' ';
	}
}

And this is the code I'm using to call it:

+ Code Snippet

WrapText( "Small cracks in the rock underfoot glow with an (understandably) unearthly light.",550, 110, 110 );

Why does this happen? The problem doesn't occur if I remove the " || Text[CurrentChar] != ' ' " But I need that to make the lines break only on spaces. ><

I guess it is because your Line character array does not have a null terminator, so dbText does not know where the string ends. Try adding this line just before calling dbText:

+ Code Snippet

Line[LineChar] = 0;

If you do this, there should be no need to fill the Line array with spaces as you do in the "for" loop at the end, since characters after the terminator will not be displayed even if some are remaining from the previous line.
