Can you put functions into a table?

Can I put a few functions into a table and then call them individually?
For instance tableA{} has 4 functions in it. My variable n changes depending on circumstances. I would then want to call a particular function from that table.
I have tried it and it hasn’t worked. Is possible?

Quick answer yes. If someone doesn’t show you, I will soon.

It is very possible. Post your code, you pby have a syntaxt error.

God damnit Dave! You shot first again!

@Circussmith Thy this.

function setup()
    for z=1,#tab do

function a1()
    print("function a1 executed")

function a2()
    print("function a2 executed")

function a3()
    print("function a3 executed")

@Jmv38 Honest, I’m not trying to beat you. I just see a question that needs to be answered, so I respond. Alot of times someone else answers while I’m putting together an example so I’ll skip the response or post the example if it’s different from what’s there.

@Circussmith - I have a couple of posts about this. It is a really cool feature.

(See reference in there to an earlier post as well).

@Dave1707 i know! Just find this quite funny!

Thank you guys. Dave1707 that worked and I think will help me in what I was trying to do. Ignatz, I really liked that post and will definitely read more them.
I am a complete beginner to coding, having never done it before. I have been teaching myself to use codea for just under two months now. So please excuse this if it is a stupid question.
Ignatz in your example on tables;
When you put in things like, Elf.walkSpeed=10 is that inserting that info into the table Elf?

Elf={} --define table

–store basic info about elves
Elf.hitPoints=8 --damage
Elf.Eyesight=25 --distance seen in pixels

function Elf.Move(char)
–code follows to calculate new position
char.x=char.x+moveX --see explanation below

function Elf.Fight(char1,char2) --char2 is opponent
–code here
return hitPoints

Thanks again

dont feel ashamed. Everyone has to start somewhere.
You are correct. The following are equivalent:
MyTable[“a”] = b
MyTable.a = b

Thanks Jmv, I appreciate that. I do have a follow up question. In Ignatz example he creates a table called Elf. Then he writes Elf.walkSpeed = 10. Now in that example is he putting walkSpeed into the table at position 10 or is the string walkSpeed = 10 being put in at the next open position in the table?

You should read the lua langage link in the wiki: it explains all that.
But i’ll do it anyway:
Tables have 2 series of indexes:

  • first numbers 1,2, etc with no interruption. They are numbers.
  • then any tag: a, toto, xxxx they are strings.
    You access consecutive integer index with : for i,v in ipairs(mytable) do … End.
    You access all indexes (integers and tags) with: for i,v in pairs(mytable) do … End
    Notice the i is gone?
    You must know:
  • indexes 1,2,3,7,8,9 stop at 3 with ipairs() because interruption.
  • Indexes are in random order with pairs().

Thank you, I will read that. Your explanation was great. Thanks again.
