You can create multiple IF whatever in a single query.
if condition "one" is true
if condition "two" is true
if condition "three" if false
do something else
same amount of endif as if!
I prefer Lua because it's easier to write out & you can have as many queries as you like in a single sentence with only 1 if.
also we can create complex queries thanks to the "and" & "or" functions
if cond1 and cond2 and cond3 and not cond4 then
-- do something!
elseif cond4 then
-- do something else
notice the not before cond4... this turns it into negative value (checks if cond4 is false)
you can also use: if cond1 == true and cond4 == false etc.
