Reading and Writing Files on Xbox (possible with WASM?)

Hi,

I have some coding experience but I haven't used WASM or coded for Xbox before. I'm interested in what's possible with regards to reading and writing to files on XBox. Am I right in thinking that you can only write values (e.g. SimVars) collected at runtime to a file within the WASM sandbox and can't read from a preloaded database either? E.g. on PC I could write a DLL that reads and writes from/to a DB that I ship with the product but I can't do this on Xbox, correct?


Thanks for any clarification.

Hi @DedicatedDev,

Be it on PC or Xbox, you cannot write to files distributed within your package - however you can copy them to the "work" (sandbox) folder upon first launch and then read/write to the copied file (many add-ons work like this).

As for using a DB, I suppose it all depends on what you want to use: would it be some kind of custom DB you wrote yourself or are you planning to use a more common kind of DB? If the latter, you must ensure that either you have access to the source code and it compiles fine to WASM (by including the appropriate files to your project), or that a static WASM lib is available to be linked with your project. We haven't tried it ourselves but I suspect SQLite would be a good candidate for that kind of things.

Please let us know if you need more information on this topic.

Best regards,

Eric / Asobo
