In-Game Visual Scripting

I have been looking around for a while and i have not found what i have been looking for, maybe someone else has found something that i did not.

Currently in my game i am implementing Lua to allow programmers to control robots to do their bidding. This is not a main focus in the game and i think this will scare some people off and/or they may never have the ability to use it. I don't wanna exclude features to some players just because of their knowledge.

So to cover the players that do not know how to write scripts i wanted a visual scripting in-game. I have been looking on a few but none of them have support of in-game editing.

I don't care if its node based or like Scratch, i just want something visual to not scare that group of players away from a feature.

Budget for this is about 100$
