I use conditions if true or false is enough, ie if a light is off or on, however if it was a door's state, locked, unlocked, closed, open, I use numeric values
You can do sequence puzzles with conditions but values are a lot easier to keep track of and you can tie them in with animation,, if value name =1 then the animation frame is also 1 kinda thing.
I highly recommend creating them in the scene conditions/values tabs on the right hand side of the editor. Much easier to find & keep track of them as opposed to them being created inside of the relevant scene objects themselves.Thanks. I agree with you. Apparently there is no particular difference where to create them, it's only in the convenience of the naivgation and / or logic.
