I know that upon project creation you ought to select either computer or mobile games that you are developing. But is there a way to build one game project and deploy on multiple platforms with only its settings changed?
Hi FrankKappaPride,
Yes you can use a single project and deploy to multiple devices.
In the Project Settings you can change under the Target Hardware section you can change the two options you initially set when you created the project. I personally never change these from the default, even if testing or doing anything with Mobile. This is primarily going to change how the project looks while in the editor to get you a better representation of what to expect, but you can also use the main toolbar > Settings > Preview Rendering Level to switch between different platforms you’re targeting as well. Be aware that it will have to recompile shaders for the project, and that can be time consuming depending on your computers specs.
Also, in the Project Settings, if you scroll down to the Platforms section you can set different settings for the platforms you intend to target. For instance, on Android, you can set the minimum version of Android you’d like to support so that the game is unsupported for lower end if you’re targeting higher end mobile devices.
I hope this helps.
