Now i can really make and compile a game without have Visual Studio 2015 installed on the PC? Because i know that previus was required for make script, but now with the internal script editor i think is no more request, i’m right?
As already said here http://answers.xenko.com/questions/2282/the-new-xenko-19-is-fully-indipendent-from-visual.html
it is not a full replacement for VS.
Most importantly, you can’t debug with it. Then, the editing behavior is not exactly like you’d be used to from VS. It also doesn’t have smaller features like automatically importing / using a namespace if required.
It’s really damn useful for small edits, looking into existing code or quick fixes though!
It is not required (although recommended) to install VS2015 to be able to build your game. What is needed is MSBuild (which should have be installed as a prerequisites along Xenko). The GameStudio can build it thanks to it.
As for editing script, any text editor is enough (e.g. Notepad, Notepad++, Sublime, VS Code…).
