FileStream

[JesseParticipant]

I am having a hard time opening a file with “Filestream”. I added the file to the Import and opened it like this

Monkey

[crayon-5cba15502f4b2537074515 inline="true" ] Local dataIn := FileStream.Open("asset::table.data","r") If Not dataIn RuntimeError("unable to find data file 'table.data'") End

1 2 3 4 5 6

[crayon-5cba15502f4b2537074515 inline="true" ] Local dataIn := FileStream.Open("asset::table.data","r") If Not dataIn RuntimeError("unable to find data file 'table.data'") End

[/crayon]

but it doesn’t seem to work. I also tried it without inserting “asset::” but still doesn’t work and without #Import adding the file myself to the folder where the executable is and still nothing. all I get is the Runtime Error.

this is on Mac OS X Sierra.

Try this:

Monkey

[crayon-5cba15503260d126782819 inline="true" ] #Import "<std>" #Import "table.data" Using std.. Function Main() Local url := AssetsDir() + "table.data" Local dataIn := FileStream.Open(url, "r") If Not dataIn RuntimeError("unable to find data file: " + url) Else While Not dataIn.Eof Print dataIn.ReadByte() Wend dataIn.Close() End End

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

[crayon-5cba15503260d126782819 inline="true" ] #Import "<std>" #Import "table.data"   Using std..   Function Main() Local url := AssetsDir() + "table.data" Local dataIn := FileStream.Open(url, "r") If Not dataIn RuntimeError("unable to find data file: " + url) Else While Not dataIn.Eof Print dataIn.ReadByte() Wend dataIn.Close() End End

That did it! Thanks.
Personally, I think games should just default to the assets dir but what do I know.

Ok, The ‘asset::’ prefix (and other such ‘::’ prefixs) should only be used with Stream.Open, eg:

Loadl dataIn:=Stream.Open( “asset::table.data”,”r” )

Assets are not always stored in filesystem directories, so an ‘asset stream’ is not always a FileStream.

Personally, I think games should just default to the assets dir but what do I know.

The problem with that then becomes how do specify ‘current dir’, eg: if “table.data” means a file in assets storage (not necessarily a dir) then you’d need a different way to specify a file in the current dir – perhaps force people to prefix files in current dir with CurrentDir()+blah, which is gonna annoying a differet set of people! Or perhaps even ‘cd::’ – dunno, if you’ve got any ideas go ahead and let me know…!

No idea of how it should have been done. I tried what I thought was intuitive but none of my attempts worked. That’s why I made that statement. I just thought that a default dir for all assets/data would be a good idea just like in Monkey1 and it somebody wants to store their data in a different folder than you would go through more complicated steps. I don’t know if it’s a great or bad idea. it’s just that I got used to the way Monkey1 works. Thanks either way for taking the time Mark.

On iOS and MacOS, assuming I understand the information in this link:

https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html

Persistent user-specific files like app configuration and save game files should be stored in the user’s Library folder.

eg:
Users/Dude/Library/Application Support/TheGame/options.cfg
Users/Dude/Library/Application Support/TheGame/save001.dat
etc..

That’s why I made that statement.

No problem and thanks for the input – hope you don’t think I was hassling, just responded with ‘problems as I see it’ etc and threw some ideas around. I actually don’t remember how monkey1 did it, must have another look!

[JesseParticipant]

Thanks @impixi, It kind of makes sense. I have some applications that use that set up. I am just wondering where would data for a maze would go? I am guessing in the game asset folder but I wouldn’t know?

@Mark

hope you don’t think I was hassling,

No not at all. Other times I have but not this time.
