Any word on when/if this will be added to AGK2?

I've got a couple of projects on hold, waiting for these commands.

Hi Rich. Can you not write your own using existing file commands?

Yes, of course I can. I've been doing that.

Three points though,

1. I helped reach that stretch goal by backing at the Gold level, and Save/Load Array was one of the reasons why I kicked in.

2. A native command could be a LOT quicker than loading each element in manually. (DBPro had a plugin that was very fast.)

3. Save/Load Array for UDT arrays would really be a timesaver on many of my projects.

@Rich Sorry to say, but at the speed AppGameKit progresses, I'm afraid it could be a very long wait.

Fair enough. I was just wondering if you could make do with your own version while you wait--so your projects won't have to be on hold!

(A 'native' version is probably not going to see massive speed improvements, as you will still be limited by hard drive read/write, either way. Would certainly be convenient, however. )

Hi,

Thanks for the kick! I'll talk to Paul about this.

this is exactly what i am needing too, so +1 to this. Rich, out of curiosity how are you doing this yourself at the minute? I woudnt mind attempting a try at a manual way for now so i can continue with my project

It wouldn't be difficult.
1. Open a file to write to.
2. Loop through the array.
3. Write the contents to the file.
4. Close the file.

Then just reverse the process to load it back in again.

Or use a memblock, which should be faster.

i think we need a WriteUDT/ReadUDT before,
this can used by load/save array too.

As long as the UDT has a fixed size that will work anyway. Across all languages if you have dynamically-length elements such as strings or embedded images it cannot unless you can serialise the data.

There are lots of ways to work around not having save/load array commands.

I'm simply asking if the feature has been dropped, or if not, if it might be added anytime soon.

Rick stated he would talk to Paul about it, so the ball is in Paul's court.

As a backer I think that unless a feature has become impossible or unreasonably workable then it is fine to drop it otherwise it should be completed at some point. That's not an unreasonable request.

There are a lot of ways around most problems but a built in command is always better for a common problem.

strings not belongs the udt struct length, its just a pointer to the next block of memory. ReadWriteString we already have, can used by load/save udt or load/save array.
about images, we used only id's yet in a integer type.
so load/save array would load/save integers only.
its not wrong and also not good but ok at the moment.
same with sounds id's.

other solution to get the udt struct items as enumeration name,data type
would also be handy if load/save array will drop.

If a string has a fixed length it's an array of byte, effectively. So in many cases this is fine, because you copy data in or out. What's important is that the UDT has a fixed size.

@JimHawkins
i mean the udt definiton is always the same size and strings are always
a reference only inside this struct.

integer 4 bytes value
float 4 bytes value
string 8 bytes reference
integer 4 bytes image id
integer 4 bytes sound id

so saving this udt is
writeinteger
writefloat
writestring
writeinteger
writeinteger

think this can generate the compiler for a udt,
dim a as udt
a.save(fileid)
a.load(fileid)

the lenght about u spoke is the data that contains a udt variable,
thats is often non fixed size, i agree.

This is always how I've saved contents of an array, actually. DBP's old save/load array commands worked but I never liked using them unless I didn't want anybody to be able to modify the contents of the file. Plus I liked being able to open the file created and modifying lines to get different results without having to program a million different combinations! I basically used it as a cheater's method.

Of course it didn't work with UDTs, but I dealt with that too.

The formatting keeps messing itself up thanks to the Apollo Forums poltergeist!
