Implement in-game visual scripting

Hi

I am looking for blueprint style in-game scripting. I need to window dress a bit of player programming and I thought a blueprint style visual scripting approach would work best. I have this feeling in my gut that I will have to roll my own, so if there are any grey beards out there that can point me in the right direction I would greatly appreciate it. If anyone knows of something I could embed I would really appreciate that too.

Sorry for being vague. I’ve been hitting a lot of blanks in my research thus far.
