Lua AddEvent

[Shadowman321]

Test script with addEvent:

function onThink(interval, lastExecution)    
	doBroadcastMessage("Started", MESSAGE_EVENT_ADVANCE)
	addEvent(spawn, 2 *1000)

function spawn()
	doBroadcastMessage("It works!", MESSAGE_EVENT_ADVANCE)
end
end

Errors:

> Broadcasted message: "Started".

[Error - GlobalEvent Interface]
data/globalevents/scripts/test.luanThink
Description:
(luaAddEvent) Callback parameter should be a function.
[Error - GlobalEvents::think] Couldn't execute event: a
> Broadcasted message: "Started".
[Error - GlobalEvents::think] Couldn't execute event: a
> Broadcasted message: "It works!".
> Broadcasted message: "Started".
[Error - GlobalEvents::think] Couldn't execute event: a
> Broadcasted message: "It works!".

In game:

04:52 Started
04:52 Started
04:52 It works!
04:53 Started
04:53 It works!

Can someone explain me some things with it?
First: Why it works even with error "Couldn't execute event"? And why it does not work first time?
Second: What is correct form of use:

addEvent(spawn, 2 *1000)
function spawn()

function spawn() should be defined before it's called. So put it first.

You missed a return true.
@Korrex function declarations and definitions orders don't matter in Lua.

 

[Shadowman321]

Callback parameter should be a function.

Ahh it not help.
What parameter and what function?!?
@Korrex
I tried this before and it not help, like said Fallen.

@Fallen
You are wrong.
Now i have fully working script:

function spawn()
doBroadcastMessage("It works!", MESSAGE_EVENT_ADVANCE)
end

function onThink(interval, lastExecution)
doBroadcastMessage("Started", MESSAGE_EVENT_ADVANCE)
addEvent(spawn, 2 *1000)
return true
end

Return true ok, but i have to moge function spawn() to the top and now it work fine.
But thanks for help
