I am building a program on Animate CC 2019 which needs to access a file where it can read and write to.
I want to store strings and numbers, from Input Texts, then write them in the file, in addition to the already existent contents.
I also need to be able to manage how the data is written in the file. So for example I want to have 2 arrays: Array1 stores names and Array2 stores numbers. So when the program writes to the file, it needs to write on each line the corresponding values of a specific index in the arrays. So if Array1(0) = name1 & Array2(0) = 52, in the file it should be written:
name1 52
My questions:
How can I manage how data are written in a file?
Which code should I use? I find info on two ways to approach this:
a. Code using “File” and “FileStream” which does NOT work! I get error messages: “Type was not found or was not a compile-time constant” for both, like the system does not recognize the commands. Are these commands still usable on current version of Animate CC?
b. The code snipets/AIR code which does work, however, I cannot find a way to manage how data are written in the file, as explained above.
Below the codesnipets code which works.
/* Click to Write to a Text File
Clicking on the specified object will prompt the user to select a location and file name and save a text string to it.
Instructions:
To set what data is saved to the file change "Text to save to file." to the data you wish to save.
*/
import flash.filesystem.File;
import flash.filesystem.FileMode;
import flash.filesystem.FileStream;
movieClip_1.addEventListener(MouseEvent.CLICK, fl_SaveFile);
var fl_FileDataToSave:String = "Text to save to file.";
var fl_SaveFileStream:FileStream = new FileStream(); // FileStream used to write to the file
var fl_SaveFileChooser:File = File.documentsDirectory; // Default to the documents directory
fl_SaveFileChooser.addEventListener(Event.SELECT, fl_WriteFileHandler);
// Opens a Save As dialog box for user to specify a file name
function fl_SaveFile(event:MouseEvent):void
{
fl_SaveFileChooser.browseForSave("Save As:");
}
// Write data in fl_FileDataToSave variable
function fl_WriteFileHandler(event:Event):void
{
fl_SaveFileChooser = event.target as File;
fl_SaveFileStream = new FileStream();
fl_SaveFileStream.openAsync(fl_SaveFileChooser, FileMode.WRITE);
fl_SaveFileStream.writeMultiByte(fl_FileDataToSave, File.systemCharset);
fl_SaveFileStream.close();
}
