Easiest way to check for multiple conditions

  • #1, z UraalTuesday, 09. July 2013, 15:20 hodinky 12 years ago
    Is there some way to check for multiple conditions at once? I wish to see if all levers are in correct positions and only then execute victory animations. For example:

    If "condition 1" is true & "condition 2" is true too
then 

else


    I have tried putting if sentences inside each other like this 

    If "condition 1" is true
If "condition 2" is true
Play Awesome animations
else
else


    I have a faint idea that this might have to do something with me not understanding what is the difference between "else" and "end if" and in the way they work.

    Incase you decide to help me, thanks in advance.

    are we talking Lua here or if else queries done via the editor?

    hmm...
    ok dokie.

    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
   do something else
  endif
 endif
endif


    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 smile

    if cond1 and cond2 and cond3 and not cond4 then
 -- do something!
elseif cond4 then
 -- do something else
end


    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.

    Absolutely brilliant, thank you a lot!

    I still don't quite understand exactly what "endif" does codewise in comparison to "else". Understanding it would allow me more flexibility with using it ... ? (pretty please ^^ )

    endif is used to close the if queries.

    for instance you can have multiple queries inside of a single if or inside of an action...

    if condition x is true
 if condition a is true then do something endif
 if condition b is true then do something endif
else -- this is for doing something else if condition x is false
 do something else...
endif



    if condition a then
 do something
endif

if condition b then
 do something
else
 do something else
endif


    in Lua: we can use "else" or "elseif" ...
    elseif is better because we only need to close with one end rather than one for each if.
    in the editor we only have "else".

    Awesome stuff AFRLme, learning new stuff with Visionaire even 1,5 years since I started the project. Getting there, slowly, but getting there. Cheers once again!
