Question about lua function

naru1305 · Post by **naru1305** » Mon Jan 24, 2011 1:43 pm

Hello everybody!
I´m working on a map and found this in the BF2-documentation:

Hidden/Spoiler:

CharacterIssueAICommand: function (player, command_id)

This event occurs whenever a player issues a command to the AI. The command ID that is passed in must be translated into a string by calling TranslateAICommand(command_id). This function will return one of the following strings:

	“getintovehicle”

	“getoutofvehicle”

	“waitforpickup”

	“followchr”

	“stopfollowchr”

so my question is if anyone has ever use this function and can tell me how it works .

you can use it to trigger an even when the player issues one of the listed commands
here is an example:

Code: Select all

follow = CharacterIssueAICommand(
        function(player, followchr)
		KillObject("DeservesToBeKilled")
                StartTimer(DeservesTobBeStarted)
              end
        end,
        "followme!"
        )

this code will kill the object "DeservesToBeKilled" and start the timer "DeservesToBeStarted" when the player tells an ai-soldier to follow him
please corretc me if somethings wrong, im not really experienced with scripting

thanks for the fast answer

but i´m not a master in scripting, so where must i put this in my lua?

DarthD.U.C.K. · Post by **DarthD.U.C.K.** » Mon Jan 24, 2011 3:23 pm

put it inside the "ScripInit"-function. If you are unsure where to playce what or how to write a certain thing, look into the shipped campaignluas. you can find examples for all kind of functions etc. there.

thank you very much

now i placed it into the ScriptInit

Hidden/Spoiler:

function ScriptInit(follow = CharacterIssueAICommand(

        function(player, followchr)

      KillObject("DeservesToBeKilled")

                StartTimer(DeservesTobBeStarted)

              end

        end,

        "followme!"))

    ReadDataFile("ingame.lvl")

and then comes this munge error

Hidden/Spoiler:

I thought it was supposed to go inside ScriptPostLoad. Anyway, if that's where you put it you're missing a whole lot of other stuff in your ScriptInit, such as team setup. The second parentheses after "followme!" closes ScriptInit.

I'm quite desperate now

maybe you can tell me exactly where i must put the function and what else i must do?
against missunderstandigs, i post my whole LUA(without sound):

From the stock documentation, which you should always read first:

CharacterIssueAICommand: function (player, command_id)
This event occurs whenever a player issues a command to the AI. The command ID that is passed in must be translated into a string by calling TranslateAICommand(command_id). This function will return one of the following strings:
“getintovehicle”
“getoutofvehicle”
“waitforpickup”
“followchr”
“stopfollowchr”

In other words you have to use TranslateAICommand along with CharacterIssueAICommand.

DarthD.U.C.K. · Post by **DarthD.U.C.K.** » Tue Jan 25, 2011 11:23 am

you know, the code i posted is an example to show what you can do with the function. do you have an object labeled "DeservesToBeKilled"? no? then nothing will happen and since you dont have a timer labeled "DeservesToBeStarted" in your lua it wont start either.
what do you want to do? i thought you just wanted to know how the function works so i gave a non-specific example.

edit: oh i overread that, my fault again, so jhers what i think should work if you have an obhect and a timer called like in this example:

Code: Select all

follow = CharacterIssueAICommand(
        function(player, command_id) == followchr then
             if TranslateAICommand(command_id)
                KillObject("DeservesToBeKilled")
                StartTimer(DeservesTobBeStarted)
            else
            end
           end
        end,
        "followme!"
        )

im not sure whether to put "followchr" in quotation marks or not.

thank you very much DarthD.U.C.K., it was a missunderstanding by me

Edit: i want one(or more) unit to follow me on my map, so i think it was a missunderstanding by me to use this function for it

i come to this idea, because sometimes on my maps, units follow me, so i want to use it(maybe for a squad)
i hope you understand me and sorry for the missunderstanding

Fiodis · Post by **Fiodis** » Tue Jan 25, 2011 11:40 am

If I'm understanding the documentation correctly, I think it should be more like this:

Code: Select all

follow = CharacterIssueAICommand(
        function(player, command_id) 
             command =  TranslateAICommand(command_id)
                if command == "followchr" then
                KillObject("DeservesToBeKilled")
                StartTimer(DeservesTobBeStarted)
            end
        end
        )

But then I acknowledge I'm not a coding guru. I'm probably missing an end or a comma in there somewhere. You see my point, though - that you have to check if the result of TranslateAICommand is equal to "followchr". Your code, Duck, seems analogous to a fragmented sentence - you've got if TranslateAICommand...what? Also, after == followchr you have a "then" without any "if" before it.

Again, I'm not as sure of my own code, either - but that's how I see it.

>.< argh sorry, i put the if one line below accidentally. you are right about the two ends too, i added a third one because i though the "then" should have an end. i dont think you need an extra variable for the command, the campaign-lua uses things like "self.winningTeam == DEF" as conditions and i think you need a comma after the last end but then again im ten timesless a coding-guru than you so...

thanks for your answers, but i hope you read my edit above

DarthD.U.C.K. · Post by **DarthD.U.C.K.** » Tue Jan 25, 2011 12:07 pm

so you want to command units to follow you? you can already do that if ou press "F4" and aim at an ai-soldier.
the discussed function is triggered when you are doing this.

OMG, i´m so silly

shame on me

but i thank you very much for your help
