I think a combination is the best. I prefer without Lua but sometimes you need some Lua code lines, f.e. to rotate s.th.. The other way is you need patience, patience, patience, overview, concentration not to forget a simple condition button and a lot of stupid loop repeats written in the Vis editor.My Zeppelin example uses conditions to swap the background images, there is also a dial on a briefcase, the background version checks which image's condition is used it also switches things on and offI know - I did this 25 times on my pipe-game...
