RE: inline conditional assignment possible?

["Bilyk, Alex" <ABilyk@...>]

Unlike C[++], Lua’s assignment operation doesn’t produce a value in addition to moving bits from one location to another. So, what you are trying to do is not possible in Lua (aside from being less readable in general, IMO).

 

On the other hand I am surprised one can not say something along the lines

 

print({a=1}.a)

 

Hmm…

Subject: inline conditional assignment possible?

 

Hi gang,

 

I'm trying to assign a varible in an if statement and have its resulting value be evaluated for the if. For example:

Normal way:

 

s = project:FindSprite("Title")

if s ~= nil then

print("we have a title")

end

 

New desired way:

 

if (s = project:FindSprite("Title")) ~= nil then

print("we have a title")

end

 

But lua always complains and I've tried all sorts of syntactical variations. Is what I'm trying to do possible?

 

thx,

ando
