Function order?

Getting Started Newbie Questions
#1

Is there any way to call a function that is defined further down in the lua file? If it’s not defined in order, I get errors.

I did try searching for the answer, but not having any luck. [import]uid: 50410 topic_id: 8698 reply_id: 308698[/import]

you can use forward declaration for the function that is defined further down local func2 local function func1() func2() end function func2() print("function 2") end

You know - I tried that, but still got an error. I must have done something wrong. lol. I’ll try it again…

Yep, Here’s the error:

Runtime error  
 D:\Users\Frank\DOCUME~1\CORONA~2\Sandbox\30\game.lua:133: attempt to call upvalue 'win\_or\_lose' (a nil value)  
stack traceback:  
 [C]: in function 'win\_or\_lose'  
 D:\Users\Frank\DOCUME~1\CORONA~2\Sandbox\30\game.lua:133: in function 'trackOrbs

Here’s the source: (game.lua)

module(..., package.seeall);  
  
function new()  
...  
 local win\_or\_lose -- cannot be declared here, because it calls resetgame()  
  
 local function trackOrbs(obj) -- cannot be declared below because trackOrbs is called in resetgame()  
 obj:removeSelf()  
 o = o - 1  
 if (o == 0) then  
 win\_or\_lose("win")  
 end  
 end  
...  
--resetgame() is in here somewhere. lol - it calls spawnorbs which calls trackorbs... it gets messy.  
...  
 local function win\_or\_lose(condition)  
 if(condition == "win") then  
 display\_txt.text = "You WIN!"  
 audio.play(win\_sound)  
 timer.cancel(gametmr)  
 m\_score = m\_score + (time\_remain \* total\_orbs)  
 m\_score\_txt.text = "Score: " .. m\_score  
 won = true  
  
 resetGame()  
 else  
 display\_txt.text = "Game Over!"  
 localscore.add({score = m\_score})   
 audio.play(fail\_sound)  
 timer.cancel(gametmr)  
 won = false  
 timer.performWithDelay ( 2000, exitToMenu, 1)  
 end  
 end  
...  
end

MAYBE I have to declare it outside of the new function? I’ll try that next. Nope - still same error. ( All I did was move the declaration outside of the new() function. Maybe I declared it wrong because it’s inside of new()? )

erase local from line 17, it’s already declared as local on line 5

ok, I’ll give that a shot later! :slight_smile: Thank you. I wont be able to do any corona coding for at least 20 hrs… but I’ll let you know the results as soon as I do. [import]uid: 50410 topic_id: 8698 reply_id: 31798[/import]
