reading and writing strings - 12/20/10 18:09

I'm not so new but I am having trouble, and I saw this as something that could go in the beginner area, as I am stumped...
does anyone have an example or know of an example of reading specific strings from a file into specific strings of a text?
I can load a text using "txt_load" and I can read and write to TEXT*.pstring[x], but getting very specific pstring to pstring I am having issues. any example would be helpful.

Please give an example of what you are trying to do.

something to this effect, but it does not work...
the texts and the entitys are defined in another script that hold all the variables and filed data.....
I'd really like to just read it into one text object from a specific line and stop reading at another line, but....I have no clue how to do that....
Code:
function get_quest_file()
{
	quest_id = NPC_active.skill11;
	if(quest_id == 1000)
	{
		txt_load(dialogue_txt,"quest_1000.txt");
		file_str_write ((temp_txt.pstring)[0],(dialogue_txt.pstring)[3]);
		file_str_write ((temp_txt.pstring)[1],(dialogue_txt.pstring)[4]);
		file_str_write ((temp_txt.pstring)[2],(dialogue_txt.pstring)[5]);
		
	}
}

wouldn't you juse use str_cpy() when copy data from one text to another.

If you specify it is what you're doing there probably is an easier way to do it rather than transferring the text twice.

yes probably, but I am storing quests in separate files, and....and.......I had not even thought about str_cpy...I always have to make things more difficult...I will rewrite the function. Thank you.

well, I was able to get it to work by loading a text and just setting the text objects size with wrap flag set, then I don't need to do line feeds...but I would still like to use string compare so I can read from specific points, but I think I can figure it out....

fogman posted a good solution some weeks ago:
"fileparser"
He wrote two functions, one for strings and one for variables.
file_seek sets the reading cursor to the beginning of the file, file_find, finds the string, and the line after that reads the string or the variable after the found string.

You have to define gvFileParserHandle global when you want to use this snippet:

var gvFileParserHandle = 0;
var gvVideoMode;
.
.
.
function ReadVar()
{
gvFileParserHandle = file_open_read("yourfilename.txt");
gvVideoMode = FileparserVar("VIDEO_MODE = ");
file_close(gvFileParserHandle);
}


In the textfile you would write:

VIDEO_MODE = 8

The function will read the value right after the defined search string.

You should also take a look at strio.c in the GS include folder.
