So just skimming through other creators code as you do from time to time when I stumbled upon this line of code:

value = ifelse((var(1) != 0), var(1), (50 * (StateType = a)))

what does 50*statetype mean? I don't see how that works unless each statetype is given a value but where in the docs does it tell you that?  o_O how can you multiply a stateype by 50, what would that equate to  ???

You are missing one part, it is not 50*statetype, it is 50 * (statetype=a).

hmmmmmm, I thought the expression multiplies the outside by the inside, like standard algebra, but still what exactly was trying to be expressed here? what was the need for the statetype=a ?

"statetype = a" returns 1 if the statetype is indeed a. Otherwise, it returns 0.
This means that "50 * (statetype = a)" equals 0 if you're not in the air, or 50 if you are.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
