[HOW TO] Update Checker

Hey Guys!

I would like to show you my update checker file. Hope you find this useful.

Basically it checks a number from a link and compares it to the current. You can use it for all your plugins you would like to.

 

Great work on the updater, but shouldn't this be in the Resources subforum?

 

Good Work,
but I think there is no directlink when you upload a Plugin to DevBukkit. So you cant use this Updates as long as you dont have your own fileServer.

 

No, you should be able to check against BukkitDev plugin files afaik but there are certain terms you must abide by I believe such as how often you check / connecting to the server / download limits (as far as I remember).

 

Thanks.

Well happens xD

Not true. You can use dropbox's direct link or even githubs raw link. It's just that easy.

 

I dont know can you update a File without changing the link to the File. I havent used DropBox bevore so i dont know.

 

Well yeah. You just edit the file and thats it. Just like github. You put the raw link in the code, and you just edit the file. Link stays the same.

See: https://raw.github.com/dretax/Saving-it/master/update.txt

Also in dropbox: https://www.dropbox.com/s/9b10nmrvwgrm2zw/as.txt

I didnt know that. Then your script will be a usefull update tool.

The only thing, that i see is that when you use versions like 1.11 and then 2.0 the version 1.11 would be choosen for the update. I would use something like that:

Code:

String[] version = ?.split(".");
String[] updateVersion = ?.split(".");
boolean update = false;
 
if(version.length > 0 && updateVersion.length > 0) {
    int i1 = Integer.phraseInt(version[0]);
    int i2 = Integer.phraseInt(updateVersion[0]);
 
    if(i2 > i1)
        update = true;
    else if(i2 == i1){
        if(version.length > 1 && updateVersion.length > 1)
            char[] v = version.toCharArray();
            char[] uv = updateVersion.toCharArray();
            for(int i = 0; i<version.toCharArray().length; i++)
                if(uv.length > i)
                    if(Integer.phraseInt(uv[i])>Integer.phraseInt(v[i])) {
                        update = true;
                        break;
                    } else if(Integer.phraseInt(uv[i])<Integer.phraseInt(v[i]))
                        break;
    }
}

Then your versions can have numbers like 2.25, 1.10, 1.01, ... and the version numbers will get phrased correctly.
