Hi,
usually when you want to save game data or application data you can use the secure area, especially in iOS, how to do it with AppGameKit ? i haven't seen any command to read and write in secure area, the secure area should be supported, i know for sure, by all the OS, iOS, Bada, Playbook, Android.

There is a specified path to include to read and write in the secure area ? if not how i can perform a save usable on all devices ?

Thanks.

Apple suggest to use the secure area when you save game data, in any case at the moment any place could be good but a simple write file on iOS doesn't work, you can't write anything in the application folder. In the SDK we have used before we can easy use the Save in secure area and was so simple. Also the write command of AppGameKit seem to be a bit poor.

Any suggestion ? we do not use T1 we use T2 and would be nice to be able to save the entire data structure. Usually if i open a file for write i can save my data structure with a single write but with the commands available from AppGameKit seem to be impossible.

iOS apps are sandboxed = the app can only read & write files from within its own directory.

AGK does this automatically for you. all saved files are written into you Documents dir inside your app dir.

7RS, what commands are impossible?

you have 2 sets of simple commands, read and write. it can't be simpler than that.

check the docs and examples.

To save a structure you can easy do

write(data,size);

where data can be a structure like:



Which AppGameKit command can save the structure in 1 time same as the fopen?

OpenToWrite
WriteFloat
WriteInteger
WriteLine
WriteString

I do not see anything in the commands that can help!

I think i resolved the problem but not with AppGameKit commands, i have used the fopen, fread and fwrite commands and now the preferences and data slot seem to work.

If with the AppGameKit command i can do the same thing with a single write call please let me know.

Thanks.

There is no AppGameKit for writing blocks of data.

There are only commands to write 'discrete' pieces like strings, integers, floats or whole lines of text.

Since you are using Tier 2 and you know the size of your structure, you should be able to do fwrite and fread commands with pointers to the data object and the size of the object. (http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/))

Can you post the exact code you are using (not just the one line, but the ones leading up to it as well)?

And please post the exact error message?

For now we have changed all using AppGameKit calls and seem to be ok, not easy to save data structures but we made a function that help a bit.
