Thanks for the hint. I managed to get it down to this, which I am very happy with:
4._do //do the following block of code 4 times [ race [ BP_Cube2.instances%_rotate _wait(5) ] ]
I’ve always shied away from UE4 because I find C++ too verbose while my experience of visual scripting languages like BP has been one of painful version control and a lack of any ability to abstract away features while making things which should be very simple into monstrosities of cables. I was hoping SkookumScript would solve this issue and so far I’m very happy with what it can do. It even makes C# in Unity look bloated. I hope support continues for the foreseeable future! Now if only there was a VSCode extension to streamline the code editing process!
