Writing object variables to file qjason
I am currently doing a school project.
We are creating a snake game, not using qml.
I am now stuck on writing username and score to file in such a way that I can easily retrieve the information and list it in a table later on. I have been looking into this http://qjson.sourceforge.net/usage/ but I get errors when I make a class implemented this way. And I can not find anything on implementation, only headerfiles in the tutorial. Any advice would be appreciated.
Hi and welcome to devnet,
What about using a database for that kind of information ?
I would love to!!! :)
I need to deliver this project fully functional in a zip folder. Is this possible, with a database? :)
@sterling Yes, use SQLite - it stores the data in a file. Qt supports SQLite.
SQL to save the top scores seams a huge overkill. One of my first projects in Qt was a snake game using QWidgets, looking at the code now makes me want to puke but it worked (and I still can't beat the rat in the last level of difficulty 😜). In that case I just used a binary file see https://github.com/VSRonin/SnaQe/blob/master/Opzioni.cpp#L166 (sorry for code written in italian)
Thank you all so much! You have been very helpful. :)
I have been looking into sql lite, as it would be interresting.When I looked into it I got the impression I still needed external sources.
So I skipped it.
I will look into your code VRonin.
Thank god for google translate :)
For the last part. a zip file. yes its possible.
You just need a so called deployment folder with all Qt dlls and some sub folders. and then your .exe.
For using json, this might be of use
I still needed external sources
What external sources do you mean? Qt already supports SQLite out of the box.
But it is just a note - I don't want to force you to use SQLite :-)
