Help with Lua predicate....

[ESAc_matador]

Hello guys...

 

I am finnally going ahead doing some steps. I am starting to understand some of the basics fo Lua. I am not a programmer, nothing, zero... so it is being hard!!!

 

My question is.

 

I want to run this code

 

---- adding radio commands
local _path1 = missionCommands.addSubMenu("Ground units", nil)

missionCommands.addCommand("Moving",_path1,function() 
trigger.action.setUserFlag("100",1) 
end,nil)

---- the resto of the script
if 
trigger.misc.getUserFlag("100")== 1 then
trigger.action.outText("it works!!!!", 100) 
end
do
trigger.action.setUserFlag("100",0)
end

 

I can´t make this to work. But if I make this.... it works!

 

Once = time more 2 = load MIST

 

Once = time more 4 = load script (the radio commands)

---- adding radio commands
local _path1 = missionCommands.addSubMenu("Ground units", nil)

missionCommands.addCommand("Moving",_path1,function() 
trigger.action.setUserFlag("100",1) 
end,nil)

 

Once = lua predicate

trigger.misc.getUserFlag("100")== 1

= action load script

if 
trigger.misc.getUserFlag("100")== 1 then
trigger.action.outText("it works!!!!", 100) 
end
do
trigger.action.setUserFlag("100",0)
end

 

 

How can I make it to use it only in ACTIONS = DO SCRIPT???

Your script does the following three things in order:

1. Add the radio command that will execute a function that sets the flag

2. Check if the flag is set -- if so, display a message. But the flag is not set because the player has not activated the command yet and the flag defaults to 0.

3. Clear the flag.

 

The second solution sets up an action that is triggered by a Lua predicate. That causes DCS to regularly evaluate the Lua predicate (I think once every second). This means that there will be many "attempts" to display the message, and they all fail, until the user actually uses the command -- at that point, the next check of the flag will succeed, and the message will be displayed.

 

You can simply add the action you want to the function you pass to missionCommands.addCommand:

---- adding radio commands
local _path1 = missionCommands.addSubMenu("Ground units", nil)

missionCommands.addCommand("Moving",_path1,function() 
   trigger.action.outText("it works!!!!", 100)
end,nil)
