lua predicate function doesn't work in 1.5 beta

[wolle]

I attached a simple test mission. All it does is to wait for one second, then evaluate a "lua predicate" trigger with argument "return true". Since this is necessarily true, it should output a simple message with which I tasked the triggered action. The message never displays, but displays if I remove the lua predicate, indicating that the lua predicate command doesn't work any more in 1.5 beta. I already posted this in the mission editor's corner, and Grimes said he could reproduce it. So, I report it here as a bug.

It seems lua predicate still doesn't work in 1.5.1 OB.

Does anybody confirm this?

[wolle]

Still not working in 1.5.1:cry:

[cuervo111]

Any news on this? Still not working years later!

[FixieRider]

This would be very very useful to have working, please!

Not sure what exactly you're looking to do with the function, but would a DO SCRIPT FILE in the MISSION START trigger type work for you?

 

Speaking from personal experience I have just pulled the .LUA predicates out of old DCS 1.2 missions and loaded them into MISSION START triggers and have had success so far.

[FlightControl]

lua predicates would be really an asset if it would work. I agree!

[wolle]

Yes, this is indeed unbelievable that this still isn't working after a couple of years. It's not that that is difficult to fix, it's a rather trivial thing. Do script file is not a good replacement, since do script file can only be done as an action, not as the trigger if statement, correct?

 

Schematically:

 

if lua predicate then do .. end

 

cannot be replaced by: if something then do 'do script file' end

Chiming in on this as well. Please ED, have a look on what seems to be a simple fix.

[Delta99]

Well it seems that after 2 years and change with 2.5 this is fixed. Has anyone actually tested it yet??!!

I was trying to use LUA predicate trigger condition. I can't get it to work with the condition text simply "true".

 

I have no idea how to make this mission otherwise.

[Grimes]

You have to use return.

 

 

if whatever == true then

return true

end

[Frederf]

if 1 == 1 then
return true 
end

isn't working.

 

I also tried simply

return true

 

I know the output works since I added a |OR| Group Alive in conditional and the debug text triggered just fine.

[Grimes]

Attach the mission perhaps? It is working in the sample mission I attached.

[Frederf]

I cannot run your sample mission. It is not compatible with the current DCS version 1.5.8.12823.414.

[Grimes]

Its from 2.5, which is the subforum this post is in. The bug was still broken as of the last 1.5.8 patch.

[Frederf]

Thank you. I was searching and going by thread title. I see now that it is in OB branch forum.

[dorianR666]

are lua predicates still not working?

 

at least in "mission goals" i cant get them to work.

tried "true" and "return true", neither works
