Coming from Unity, transition questions

Not to scare you people, but to get productive in C++ you will also need good spec computer with an ssd of course. Otherwise the compilation is so slow and it will quickly wear you off.
A lot of time, code plugins bought in the marketplace will straight away plug-in ie it just works without any tinkering. However, to minimize the risk of the plugin being dead (and you are stucked), here are two considerations:

  1. Do not buy code plugins which do not sell well… even though it fits your requirement perfectly. These plugins may not get updated in the new version. You may try compile but there is no guarantee it will just work.
  2. Do not try to upgrade every time there is a new version. This way, your plugin stay intact and usable.
