There's not really any use for this, as far as i can tell. Lua supports this by its syntax sugars:

moo = (variable) and (ifTrue) or (ifFalse)

works the same as

moo = (varible) ? ifTrue : ifFalse

in C++.


oO You're right. Never thought of that. What I was thinking about, too, was something like

moo = ({ [true] = ifTrue, [false] = ifFalse })[condition]

But your code is much better. Thanks for posting this. ;D NeonBlack 22:00, 18 May 2009 (CEST)


The problem with the plain Lua version is that 'ifTrue' is also part of the test condition. Consider this:

variable = true
ifTrue = false
ifFalse = true

moo = (variable) ? ifTrue : ifFalse
== false

ElseIf works fine here:

moo = IfElse( variable, ifTrue , ifFalse )
== false

Lua's and's 'n' or's however may give unexpected results:

moo = (variable) and (ifTrue) or (ifFalse)
moo == true

it returns true because one of the two first arguments are false.

this is lua's fault.
