TransmitMessage Script

[Colmillo]

Hi!!

I have this script (works perfectly):

FL = 1
local function redGroupFirstLine()
timer.scheduleFunction(redGroupFirstLine, {}, timer.getTime() + 5)  

if trigger.misc.getUserFlag('RArm2') > 0
and trigger.misc.getUserFlag('RArm3') > 0
and trigger.misc.getUserFlag('RArt1') > 0
and FL == 1
then
	trigger.action.outTextForGroup(187, "Blue Group is going to first stop",10)
	trigger.action.outText("Blue Group is going to first stop", 5)
	trigger.action.activateGroup(Group.getByName('RED_SA6'), 1)
	trigger.action.setUserFlag('FirstLineOut', true)
	FL = 0
end
end
redGroupFirstLine()

But, I want to insert a 'TransmitMessage' when the flag 'FirstLineOut' is true, and I can't...

This is the message script:

   local msg = { 
     id = 'TransmitMessage', 
     params = {
       duration = 5,
       subtitle = "The first red line is accessible, \narmor 1 and 3 are proceeding to the first stop.",
       loop = false,
       file ="l10n/DEFAULT/KOH_firstline.ogg",
     } 
   }
Group.getByName('BLUE_ARMOR-2'):getController():setCommand(msg)

Thanks in advance

Instead of setting the flag, why not just use TransmitMessage right there?

[Colmillo]

While I'm looking for a solution, I created a trigger that when the flag is true --> do script (and there I write what generates the message)

The main reason is that I use scripts in several missions, so the less I have to configure in the Mission Editor, the better.

In that case, check that your flag name is IDENTICAL.  It's really easy to have a different capitalization or a one letter typo and it won't work (i.e. FirstLineout is not the same as FirstLineOut).

I found out!!!
I forgot to insert "do" after "then", here's how it works:

MS = 1
local function message()
timer.scheduleFunction(message, {}, timer.getTime() + 5) 
if trigger.misc.getUserFlag('FirstLineOut') > 0 and MS == 1
then
do
local msg = { 
     id = 'TransmitMessage', 
     params = {
       duration = 15,
       subtitle = "The first red line is accessible, \narmor 1 and 3 are proceeding to the first stop.",
       loop = false,
       file ="l10n/DEFAULT/KOH_firstline.ogg",
     } 
   }
Group.getByName('BLUE_ARMOR-2'):getController():setCommand(msg)
end
MS = 0
end
end
message()

Thanks for the comments.

Cheers

I'm happy it works for you, but I doubt that that was the root cause. There is no need for a 'do' after a 'then'. It's more likely that you had an extra 'end' somewhere, but that is not visible from the code that you originally posted

You may want to balance your code with some indentation to better see what level you are on. Something like this:

S = 1
local function message()
	timer.scheduleFunction(message, {}, timer.getTime() + 5) 
	if trigger.misc.getUserFlag('FirstLineOut') > 0 and MS == 1 then
		do
			local msg = { 
				 id = 'TransmitMessage', 
				 params = {
				   duration = 15,
				   subtitle = "The first red line is accessible, \narmor 1 and 3 are proceeding to the first stop.",
				   loop = false,
				   file ="l10n/DEFAULT/KOH_firstline.ogg",
				 } 
			   }
			Group.getByName('BLUE_ARMOR-2'):getController():setCommand(msg)
		end
		MS = 0
	end
end
message()

In above code you can delete the 'do' and the 'end' before MS = 0

you're right, I never thought the indent was the problem.
Thank you so much

As long as it's coded correctly you don't need any indentation at all.  Indentation just realllllyyyyy helps debug what's going on in a much more visual way than having to trace through the code and figure out what belongs with what (i.e. what END goes with what IF or what DO).

Mmm, yep... looking again, I found something very curious:
I think the real problem was this:

if trigger.misc.getUserFlag('FirstLineOut') > 0 and MS == 1
then

"Then" in the next paragraph, and the correct thing is:

if trigger.misc.getUserFlag('FirstLineOut') > 0 and MS == 1 then

The curious thing is that the "then" error was corrected with the "do" afterwards in the next paragraph.
I think I will never finish knowing the scripts 100%

most likely you had an invisible control character messing up the script. Both versions are perfectly legal lua code and should not produce an error.
