How do i collaborate with my friend in unity (without paying)

i want to work on the same project with my friend and am currently using dev ops but when i make a change and, commit it my friend cant see that change on his monitor someone help pls, is this even possible, to see my work on his screen from a diffrent pc

Not sure what dev op tools your using but I like to use GitHub for source control. For video chats / screen sharing I use Slack. I think the free version of slack might only allow two people in a meeting. There’s also visual studio live share, where you can shared code at the same time but I’ve never used it.

VSC Live Share works well, using it regularly for pair programming.
That’s for code though, not for Unity scenes.
Even with git, it is unfortunately overhead intensive in best case and neigh impossible worstcase to colaborate.

Therefore in most cases projects tend to break down the scenes into separate ones so no two people work on the same scene at the same time.
Scenes can be loaded ontop of another, giving you some flexibility for example to have person A work on an enemy fortress while person B works on the players fortress → At game start you just load both scenes into the actual world scene.

I’d recommend just using git and that approach.
Just in case you are new to git (what you should change asap :wink: ): The recepient of changes gotta “git pull” to see the changes. Unity will then update and make them visible on screen.
