Help on multi-platform?

Hello,
Finally finished my game but ran into a problem on making my game multi-platform. Can someone explain how to do this?
Thanks in advance!

What platforms?

Have you tried simply creating a build for that platform and seeing what happens?

I meant to make it available for multiple devices, for example ios, mac, android, etc in the build settings

Open up the build settings, switch platform, and try to make a build.

If it is a PC game, it should hopefully “just work” on mac. iOS and Android are more complex. The build may just work, but you have to consider different input methods (touch screen instead of KB+M) etc.

Wait so if i switch the platform it doesn’t switch the current platform i am on?? Btw I’m just trying to build it for Mac and IOS

I don’t understand what you are asking.

If you are trying to make a Mac build, just select Mac and select build.

I am trying to build my game for mac and IOS because when I test it on xcode only 1 will work based on what platform its built on in unity, so I need to make it buildable in IOS and Mac

Select IOS and hit build, then select Mac and hit build. You will have to re-import the project each time, but that is an automated process.

ok that worked but just out of curiosity how would you do this if your game is multiplayer? Do they just sync or is that another process?

Run the games on their platforms and try and connect. See what happens, and fix any errors you get.
