How to catch build event

[Phelom]

Hi guys..

I'm creating a map, in the script file i want to catch a build event :

When a player creates/builds something, i would like to call a function to do something else...

Any help ?
Thanks

Code: Select all

Supreme Commander - Forged Alliance\gamedata\lua.scd\lua\ScenarioFramework.lua

Triggers are at the beginning,
maybe this one? line 242

Code: Select all

function CreateUnitBuiltTrigger( cb, unit, category )
    TriggerFile.CreateUnitBuiltTrigger( cb, unit, category )
end

Thank you, but how to catch it then in my own script ?

For example, i want to check if the player has created a specific unit (land factory for example) then display a message... so how should i do ?

first you need to import ScenarioFramework at the beginning of the script

Code: Select all

local ScenarioFramework = import('/lua/ScenarioFramework.lua')

Then in function OnStart you set up the trtigger, cb is your callback function

Code: Select all

ScenarioFramework.CreateUnitBuiltTrigger( cb, unit, category )

Try to play with it around a bit, maybe you will need different one for proper functionallity.

Actually Ive noticed that ScenarioFramework is taking triggers from this file:

Code: Select all

Supreme Commander - Forged Alliance\gamedata\lua.scd\lua\scenariotriggers.lua

You might find some more there, Im sure one of them will work as you want. If you will use triggers from this file, import it and use as I decribed post above.
Good luck

I tryed this

Code: Select all

function OnStart(self)
   ScenarioFramework.CreateUnitBuiltTrigger( cb, unit, category )
end

cb = function(cb, unit, category)
   
   BroadcastMSG("Well done !", 8);

end

BroadcastMSG is just a function to print text, but i got nothing when i build something,

Any help ?

I guess i have to add unit code in the function right ? if so, where can i find those codes ?

categories list http://wiki.faforever.com/index.php?tit ... Categories

I think you will have to define unit first for this to work, YourFunctionName is the name of your function, it can be whatever. Dunno how broadcasting some message works. Im sure its in lua files and might be used in some survival maps. You can copy it from there.

Code: Select all

function OnStart(self)
   ScenarioFramework.CreateUnitBuiltTrigger(YourFunctionName, unit, categories.FACTORY * categoriesTECH1)
end

function YourFunctionName()
   BroadcastMSG("Well done !", 8);
end

category can be also specific unit, then you use unit ID, example: categories.uel0001
use UnitDB for finding IDs http://content.faforever.com/faf/unitsDB/
