If statement using multiple "or" condition [syntax question]

Getting Started Newbie Questions
#1

Hey guys, 

Is there a syntax in lua for using multiple “or” condition?

Say for example I want to do this:

if (gamePhase==1 or gamePhase==2 or gamePhase==3 or gamePhase==4 or gamePhase==5) then

– do something

end

#2

What you have written is the only way

#3

For some reason my post was incomplete,

My question was, is it possible to do something like this instead to shorten the code:

[lua]

if (gamePhase==1,2,3,4,5 ) then

– do something

end

[/lua]

 

But from your answer I can tell there is only one way, the long way…

 

Cheers!

Roy.

You could make a function to do it for you?

function multipleOr(obj, table) for i = 1, #table do if obj == table[i] then return true end end return false end function multipleAnd(obj, table) local allTrue = true for i = 1, #table do if obj ~= table[i] then allTrue = false end end return allTrue end if multipleOr(gamePhase, {1, 2, 3, 4, 5}) then --do something end if multipleOr(event.phase, {"began", "moved", "ended"}) then --do something end

Edit: Just realised that I actually made an “and” statement function. I’ve edited it to be an or statement (and included the and function separately.

Thanks for the suggestion Alan!

See my edit, I made the wrong function the first time.

You do not have to even use table - Lua function can have variable number of arguments so you would even do function like OrFunc(compared, …) [dots literally]
