“The Coding Experience”
He uses “Visual Studio 2015”, but I don’t have it.
How and where can I create code?
Hi @kiridu1988.
While Visual Studio is not required, it is a recommended IDE. The community edition is free of charge and can even be used by individual developers for commercial projects.
You can use any kind of text editor or IDE you want. For example Visual Studio Code or MonoDevelop should work. To edit the code you can either open it in the integrated editor or define an external editor in the settings and right-click on a script to edit it with it.
On the other hand, MSBuild is required to be able to build the project from the GameStudio. While that tool is now separated from Visual Studio, it does use the same installer.
