I could use some help. How do I save variables to a binary or text file and read it again in Unity with C#? Everywhere I look recommends to save by serializing or JSON for human-reading for human view, but I am not concerned with that. C seemed to allowed it pretty easily to save in binary, but, to me, 100 lines of code seems silly to save in JSON for sake of readability

what kind of variables do you have?

is it in a class?

It is just a few integers (and no they are not in a class, I hardly even know what those are)

if you want to write individual primitives, you can use BinaryReader/BinaryWriter

Not in the docs. What is it exactly?

the issue is that if your format never changes, you can just write some values. but for example, if you ever want to add a header to your file or re-order some fields, then everything breaks, which is why people recommend serialization

oh ,these aren't Unity, these are .NET classes

docs.microsoft.com/en-us/dotnet/standard/io/…

OH. Crap. I am thinking of just sticking with PlayerPrefs....

All what Google has offered is alot of complex, secure, and human-readable formats, none in which concerns me with my little pet project.

I imagine Unity probably has an odd set of APIs because its API needs to work on phones and web and consoles where you might not have the same kind of files as on PC

Of course it does.... What is a "Class" in C#?

a class is like a class in C++

it's like a struct in C, roughly

Or more of "Why does Unity even add the scripting documentations on complex stuff? They don't explain it at all"

in C#, and languages like it (i.e. Java), all functions live in a class

Ok. A structure...

so in C, where you had global functions printf and fprintf to write to the console and to a file respectively, in C# you have things like System.Console and System.IO.StreamWriter which are structures

Ok... is it like C where you define a location and the variable and it writes to the location?

hmm, there's several ways to do this. maybe I'll show you the "dumbest" way since it might be the easiest to understand

Please

StreamReader and StreamWriter kind of just write a line of text to a file

You can ask StreamReader to read a line of text, and you can then call int.Parse() to turn that string into an int

for example, int.Parse("345") == 345

Wait, how could I parse any string number into an usable integer?

Nvm. I think I almost got it

It is telling me "Input String was not in the correct format"

I got it!

yeah if the ReadLine returned something like an empty string, or "x" then it will not work

I gotta go to bed. Thanks for the help. Might come back for more help on this within the next few days. Bye

later

I'm idly considering making a flight simulation video game.

Like Kerbal Space Program, but all about atmospheric flight, no spaceflight.

("Kerbal Air Program"?)

So, designing planes (and other aircraft, like gliders and helicopters) and then flying them.

The "tricky bit" is the flight model.

If I were to do this, I'd like to not half-ass the flight model; I'd like to get something reasonably realistic. Where, if you build a replica of a Cessna 172, it'll at least kind of fly like a Cessna 172.

Now... I'm guessing I can't just grab an aerodynamics simulation package from GitHub and use that. :D

I think they say that X-Plane is the most realistic flight simulator. So ideally I'd use the X-Plane aerodynamics model... but even if that were technically feasible, it would probably be prohibitively expensive to license it.

I've got a reasonable idea for how to "fake it". Just simulate the aerodynamics for each individual part and add all that together. I can use raycasting to make a not-completely-awful simulation of blanketing.

Now all I gotta do is... win the lottery and then quit my job so I have the resources to actually do this.

github.com/gabrielevierti/OMGE/blob/master/Engine/… it's working now, i also wanted to use find_library(), but the cmake specification does not provide any example of its usage..

find_library (<VAR> name1 [path1 path2 ...])

@Josh I remember trying that, but it didn't work..

oh, okay then. thanks

oh yeah i remember using find library, i just didn't put the .lib extension after the name

find_library (glfw_lib NAMES glfw3.lib PATHS ${CMAKE_CURRENT_SOURCE_DIR}/lib)
find_library (irrklang_lib NAMES irrKlang.lib PATHS ${CMAKE_CURRENT_SOURCE_DIR}/lib)
find_library (vulkan_lib NAMES vulkan-1.lib PATHS ${CMAKE_CURRENT_SOURCE_DIR}/lib)

target_link_libraries (Omge glfw_lib irrKlang_lib vulkan_lib)

target_link_libraries does not seem to treat the variables like libraries..

they are all found

they all point to the correct folder and correct lib file
