function in table?

[the underminer]

I want to be able to store functions in tables like

Code: Select all

special = {1,2,3,enemies()}

if X == 2 then
      special[4]
end

It doesn't work like described above, though. Anyone knows how to do this?

Try this:

Code: Select all

special = {1,2,3,enemies}

if X == 2 then
      special[4]()
end

[the underminer]

That nearly works, but at the same time it doesn't.
Luaplayer doesn't give an error on storing 'enemies' (without quotation) in a table, but when calling special[4]() it gives an error: problem indexing field '?' (a nil value). I checked that i = 1 and enemies was stored on place 4. What to do?

For the two dimensional array, you need to create a table within a table. Did you do that?

Code: Select all

Enemy = {}
Enemy[1] = {13,5,0,0,1,0,12,17,1,30,0,enemies}

function CalcEnemy()
i = 1
print(Enemy[i][11]) -- this works, gives 0
Enemy[i][12]() -- error here
end

function enemies()
(..) -- big ass function here
end

Yeah, it seems I did

I see you did alright but...

The function 'enemies' should be moved above in order to declare it sooner than using it.

[romero126]

variable = function (param) do stuff here; end

[KawaGeo]

Both function syntax work the same but the latter makes more sense if it is used as a variable.

You're absolutely right... And I thought I wasn't a noob anymore. Works fine now, thanks 2 all
