Thread: [PI] Updating Character files while they are offline

Add in PlayerSave.java

Code:

    public static void updateCharString(String charName, String lineContains, String replaceWith) {
        String filePath = "./data/characters/"+charName+".txt";
        try {

            FileReader charFile = new FileReader(filePath);
            BufferedReader br = new BufferedReader(charFile);
            String line1 = br.readLine();
            while (line1 != null) {
                if (line1.trim().contains(lineContains)) {

                    line1 = replaceWith;
                }
                BufferedWriter out = new BufferedWriter(new FileWriter(filePath + ".tmp", true));
                out.write(line1);
                out.newLine();
                out.close();

                line1 = br.readLine();
            }
            br.close();
            charFile.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        File file = new File(filePath);
        file.delete();
        File file2 = new File(filePath + ".tmp");
        file2.renameTo(file);
    }

Usage:
PlayerSave.updateCharString("arrowzftw, "special-amount", "special-amount = 100");

What this will do is replace all lines that contain special-amount with special-amount = 100

So if i had in my file:
special-amount = 10000;

It'll be replaced with:
special-amount = 100

Useful for something like an automated lottery.
