@Titaniumammas69 You uploaded your game to a site but you did not test the Linux and MacOS builds before doing so, is that it?

11:16 AM

@Vaillancourt yes...

It said linux windows and mac so it only made sense it would support linux

@Titaniumammas69 I haven't played with unity there but I suspect you need a linux machine yo produce the linux build. You need a linux machine to test it, at least; you don't want to release a build that you haven't tested :)

@Vaillancourt thinking about that... could I run a virtual desktop with linux as the platform and export it as linux?

or convert the .exe file to an .elf file?

the conversion may not be supported by the assets with the export tho

You vant convert an exe to a linux exe, but your vm approach would probably work.

I think converting is rather complicated and not readily available. A VM is easy and works though.

I'm fairly sure Unity can spit out Linux binaries on Windows

Q: Why I can't do a build for Linux?

11:28 AM

@Tyyppi_77 It cant on my computer

I am downloading a virtual machine rn

user92578

I'm using Unity 5.3.x (free version) on a Windows machine. I would like to build my simple desktop game either for Windows and Linux, but Linux (and Mac) build is disabled. Am i missing something ? Thanks

unity

Good UI would not disable the selections and instead tell the user that support for that platform is not installed, ask if they want to install it and start the installer if the user confirms.

user92578

Yup, just replace the "Make build" button with an "Install platform support" button

this looks good

I have to re-install unity?

user92578

No, theres probably something somewhere that just lets you add components to the installation

11:34 AM

hmmmm

Running the installer and adding a checkmark should do the right thing.

@nwp which installer do I run?how I got unity was I used the unity hub then downloaded the actual unity but reinstalling the unity hub doesnt have the options

docs.unity3d.com/Manual/…

omg thanks so much

user92578

"unity install linux build support" -> 3rd link

@Tyyppi_77 you can post that answer on the question gamedev.stackexchange.com/questions/184230/… so i can give you more reputation and make it the answer

@Tyyppi_77 yes, I think so too, but it still would be more prudent to test it on the target platform before uploading it!

yes

its still downloading the build setting

but i will test it soon

user92578

I'm not actually sure what you were initially asking, but I can post this as an aswer if this solves what you asked

Building outside of the VM might still be worth it. Assuming building takes more resources than running.

I was trying to export a build for linux

The question to me reads "I exported a Linux build, but a customer said that the game doesn't work on Linux"

user92578

Replies are usually unnecessary when there aren't multiple conversations going on at the same time :)

yes

oh ye i earned the vote up privelage

only 35 more rep till i can comment

user92578

I liked gaining rep in the beginning, the next goal always seemed nice and accessible

user92578

Now I need 4.3k till the next one :D

rip u

@Tyyppi_77 I realized that applying to a mod election helped a lot in gaining privileges :p

@Tyyppi_77 Yeah. Even though StackExchange is already my favourite RPG to grind, they could still use some game design love in the progression system...

user92578

Luckily I can copypaste Unity docs and get a nice +45

DMGregory

Yeah, sometimes I wonder if I should change my job title to "professional Googler"

@nwp How do you handle resources with your message bus? I implemented a wrapper over std::queue<std::function<void()>>, and things work fine until I need to move an allocated std::unique_ptr<World> into the function that is invoked on the UI thread, so that the allocated World can get assigned into the correct member, as the wrapping lambda now becomes a move-only type which can't be stored in a std::function?

user92578

I solved the issue by releasing the unique_ptr into the lambda capture, and then unique_ptring it again at the start of the lambda but this feels extremely dirty

user92578

The high level idea here being that a thread does make_unique<World> (the expensive bit), and then it is safely assigned into the owning classes std::unique_ptr<World> m_World once ready by pushing a lambda that does the assignment into the message bus

user92578

5:47 PM

yeah man ugh i am in unique_ptr hell

My uninformed guess is that you're using unique_ptr for something it's not meant for.

user92578

I have too many nested levels of stateful lambdas, most move-capturing which makes me feel like this "simplification" of avoid std::future is a very bad idea

user92578

Input recordings are huge so I want to avoid copies as much as I can

6:03 PM

Why are you trying to avoid std::future? I mean, I probably would, I'm just wondering what your specific reason is.

user92578

Well I was looking for a pattern of avoiding the duplication of the future and then the actual storage for the data once the future has been filled, and nwp suggested yesterday a message queue pattern, where I queue code the be executed in sync on the main thread which fills the role of the future

ah ok

I think I get that.

user92578

In theory this seemed really nice, just assigning to a class member inside a lambda, and throwing that lambda onto the queue

user92578

But this is turning out to be a nightmare in terms of keeping the data alive until the assignment
