Angrybirds – Custom Levels (Made easy)

It’s back again and this time thanks to our great friend Cgarvie over at talk.maemo.org who has now made the installation process much much easier.
If you not 100% whats going on, you might remember I posted a few months ago about making custom levels for the game Angrybirds. If you missed it head over and see what I had to say: Angrybirds – Custom Levels
The current thread that deals with all the questions/suggestion for the Angrybirds Custom levels is here: Angry Birds Custom Levels.
So Instead of me trying to translate the thread I went to man behind the work, who is no other than Cgarvie.
So the first thing to do is to get the file: download here
Next is to read what Craig had to say:

Ok lets start with my Post to the Forums

************************************************** **********************
But first GO and buy the Rovio expansion pack. Its much simpler if you do this first.

Then Download the file attached to your N900. How you do this is upto you.

BUT DO NOT COPY THE FILE TO THE ROOT OF THE DEVICE.
ITS BEST COPIED INTO YOUR HOME DIRECTORY

untaring the file in the root of the device will take up valuable space and MAY CAUSE PROBLEMS

THEN ALL AS ROOT.

run
tar xzf custom-release.gz
cd custom

sh setup-cust-AB
this sets up AB to be custom level compatible.

sh run-cust
this allows you to play custom levels

sh run-rovio
changes back to rovio levels;

these 2 commands used to switch back and forth as you effectively swap the game between custom and official levels

sh reset
should be run before upgrading OS or buying rovio levels(i think) but is otherwise not needed
*****************************

Ok so the First bit would be simple if it didnt keep disappearing from the online shop. But i cant stress this enough Rovios beer great help, and very generous allowing me to tinker around.

SO onto the Install

FIrst a Warning. You should really try to understand what your doing if you tinker. I am not responsible for any trouble you get into. But i will try to help you if you do.
Saying that this is fairly simple and i will try explain whats happening.

You will need to have root access so see else where for that. And take REAL note of the Warning. Having root access is great but can be dangerous.

there really 2 options Dowload on a different machine and copy to phone or download from phone

either is as good as the other as long as you end up with the tarred file is on you phone and NOT (listen up folks) NOT in the root area. There whole threads about the problems filling the root area up

So /home/user
seems a good and sensible place.

Ok now you have a tarred and zipped file but thats not use to man nor mouse , so we need to unzip and untar

enter
tar xzf custom-release.gz
at the command line

This does as i suggested. it unzips (z option) and unpacks (x option ) . But google is you friend so go find out more about tar.

This should create a Directory called custom.
If i need to explain
cd custom

then you should give up now, and go do something less boring instead

now onto the clever bit
sh setup-cust-AB
this sets up AB to be custom level compatible.

sh runs a shell script. Shell is a basic programming language.

This checks if AB is running and moans if it is
It then moves all the Rovio files aside and copys my levels to the AB structure.
It then sets up symbolic links (go google again) that point to the Angry bird levels and level info

The 2 other scripts
sh run-cust
sh run-rovio effectively just move the symbolic links to point to rovio or custom levels

the final part
sh reset
should return the setup to how it was on AB install.
a sensible move before upgrading AB or the OS.

Hope this helps
Craig

I want to thank Craig for taking the time to explain, some of you might find some of his words “harsh” but to be honest, if you don’t understand and you are getting stuck, please google and/or ask for help, because the last thing we want is for you guess and then end up damaging your phone.

So To Summarise:

1. Extract Files (tar xzf custom-release.gz)
2. Go to your new custom folder (cd custom)
3. Setup Angrybirds to be custom level compatible (sh setup-cust-AB)
4. Play custom levels(sh run-cust)
5. Play normal levels(sh run-rovio)
6. Reset everything to the way it was in the beginning(sh reset)
