Hello,

I'm trying to make a small Update Check for my mod. I already have a .txt File on my Server, but now i don't know how to check the lines with Forge and then check it with my mod_version. I only want to do that, when the player joins in the world. The Function for that I already have, because I've there some other steps.

 

Could somebody help me?

have you tried normal Java I/O

 

read the file with InputStream then check if it matches anything

I created a class named UpdateCheck:

 

package test.misc;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.util.Map;

import cpw.mods.fml.client.FMLClientHandler;
import cpw.mods.fml.common.Loader;
import cpw.mods.fml.common.ModContainer;

public class UpdateCheck {

private final String updateURL = "MyURL";

private class UpdateCheckThread extends Thread
    {
        @Override
        public void run()
        {            
            try
            {
                
                Map<String, ModContainer> modMap = Loader.instance().getIndexedModList();
                ModContainer Mod;
                
                URL versionDataFile = new URL(updateURL);
                BufferedReader reader = new BufferedReader(new InputStreamReader(versionDataFile.openStream()));
                String curLine;
                while ((curLine = reader.readLine()) != null)
                {
                    String[] tokens = curLine.split("=");
                    if ((Mod = modMap.get(tokens[0].trim())) != null)
                    {
                        if (!isModUpToDate(Mod.getVersion(), tokens[1].trim()))
                        {
                        	FMLClientHandler.instance().getClient().ingameGUI.getChatGUI().printChatMessage("A newer version of Test is available: "+tokens[1].trim()+", get it at test.net");
                        }
                    }
                    else if (tokens[0].trim().equals("mc"))
                    {
                        if (!Loader.instance().getMCVersionString().equals(tokens[1].trim()))
                        {
                            System.out.println("According to website, current mcversion is: "+tokens[1].trim());
                            break;
                        }
                    }
                }
            }
            catch (Exception e)
            {
                System.err.println("Error while checking for updates:");
                e.printStackTrace();
            }
        }

        private boolean isModUpToDate(String localVersion, String webVersion)
        {
            boolean newer = false;

            for (int i = 0; i < Math.min(localVersion.length(), webVersion.length()); i++)
            {
                int comparedchar = webVersion.substring(i, i + 1).compareTo(localVersion.substring(i, i + 1));
                
                if (comparedchar < 0)
                    newer = true;
                
                if (!newer && comparedchar > 0)
                    return false;
            }

            if (webVersion.length() > localVersion.length() && !newer)
                return false;

            return true;
        }
    }
}

 

How can I initialize it when the player joins at OnPlayerLogin(EntityPlayer player) ?

You can use an IConnectionHandler registered with NetworkRegistry.

I'm using IPlayerTracker for that. The problem is when I add that to OnPlayerLogin, nothing happens:

 

new UpdateCheck();

How are your running the thread ?
