 |
|
I want to be able to store functions in tables like
| Code: | 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: |
special = {1,2,3,enemies}
if X == 2 then
special[4]()
end

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[i][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: |
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.

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