table find

[drk]

Hi. I need help with "find a string in the table".

Here the code:

-- Anims by Ezz 
  
Anim            = { } 
Anim.__index    = Anim 
  
local validTypes = { 
    pulseOut        = true, 
    fadeIn          = true, 
    fadeOut         = true, 
    move            = true, 
    moveResize      = true 
} 
  
function Anim:Create ( aElem, aType, aTable ) 
    if ( validTypes [ aType ] ) then 
        outputChatBox ( "Passed statement" ) 
    end 
end 
  

If I use "if ( validTypes [ aType ] ) then" and I put "myAnim = Anim:Create ( myElem, pulseOut, { } )" or other thing in pulseOut it doesn't output nothing. If I put "if ( not validTypes [ aType ] ) then" when I put something who isn't in the table it output anyway.

Any help?

Anim:Create ( myElem, pulseOut, { } ) — pulseOut here is not a string, it's a variable, probably nil.

if you're still making this kind of errors, perhaps it's not the time to dive into OOP and classes.

You need use metatables for create something like oop.
