hi,

im doing calculation in hierarchical way below are my details

CREATE TABLE `nodes_1` (

`parent` int(11) DEFAULT NULL,

`child` int(11) DEFAULT NULL,

`marks` int(11) DEFAULT NULL

)

data:-

pastedImage_0.png

in a query if i pass 5 as parent that calculate 2,3 child marks

and the same if i pass 15 as parent that should calculate 10,5 marks --5 already having 2,3 child. Result would be 200

same if i pass most parent 38 it should calculate 15,17,6 child marks --15 already holding 200 marks ,17 has two childs 9,8 marks ,6 no marks --result 230 e.t.c

thanks in advance.

Found it out in the meantime, apparently there's a folder JavaPuzzleBall_SaveData in the home directory/folder containing 3 files which corresponds with the three categories in the puzzle game (basic, inheritance, lambda).

Each file contains a 0 or 1 value which indicates if you completed the puzzle or not. During startup there's probably a check if the files exist, if not they are created and initialized with zeroes.

Now you know this, don't try to "hack" the stuff ;-)

ha ha, yep, that's it.  It's very hack-able.  At the time, I wasn't sure if the game would be played in a browser, downloadable, or both.  The data is saved locally for two reasons.  First is because that's what I knew how to code.  Second is because I didn't want people to lose their progress if they played online and decided to download later.
