Ok so how what do I write to make it work? OnCPCapture?

Almost correct.

Let's play another game. See if you can find the right one in this document: https://sites.google.com/site/swbf2modt ... ing_system

I think I see the problem regarding the original issue and Skinny's script. This:

Code: Select all
if IsCharacterHuman (character) then

Should be:

Code: Select all

if not IsCharacterHuman(character) and GetCharacterTeam(character) == REP then

^That, and he also was not supposed to use the below code, which is from Ambush.lua and is called externally.

Marth8880 wrote:@Anthony: The problem with SetupAmbushTrigger is that it only proceeds if the character entering the region is human:

Code: Select all

--Designers: use this function to set up an ambush (don't call Ambush() directly, please)
function SetupAmbushTrigger(ambushRegionName, spawnPathName, numDudes, fromTeam)
    local trigger       --must be declared before being used
    trigger = OnEnterRegion(
    	function(region, character)
			if IsCharacterHuman (character) then
			    Ambush(spawnPathName, numDudes, fromTeam)
			    ReleaseEnterRegion(trigger)
			end
    	end,
        ambushRegionName
        )
    ActivateRegion(ambushRegionName)
end

Keep in mind text values like REP belong inside ""

Just a head's up to save you from more errors down the line. Only numeric values do not need "" in Lua.

REP isn't a string though, it's very much an integer.

My bad, I remember Zerted telling me something like that, I guess I took it the wrong way. In fact using "" on REP might be causing his crash issue.

Code: Select all

OnEnterRegion(
    function(region, character)
   if not GetCharacterTeam(character) and GetCharacterTeam(character) == REP then
        Aumbush("ambushregion", "ambushpath", 8, 5)
    end,
 "ambushregion"
 )
    
 end

end

Nope, I`ve also tried it with 1 "end", still shows errors.

EDIT: I put this code in my LUA -

Hidden/Spoiler:

[code]

OnFinishCaptureTeam(CaptureTeam1, 1) KillObject("cp4")[/code]

The idea was that when the Republic captures cp3, cp4 will disappear, but cp4 disappears at the start of the game anyway? I don`t know how to set this out, I read that documentation on this code stuff and it didn`t tell me how to do this.

Almost correct! That if-statement needs to be closed, try putting a single end in a new line after Ambush is called. Also remove that stray end at the very bottom of the code you posted.

Go ahead and read through this section of Programming In Lua for a better understanding on how to implement if-statements: https://www.lua.org/pil/4.3.1.html

As for OnFinishCaptureTeam, it needs to be registered properly as an event callback. Simply using OnFinishCaptureTeam(CaptureTeam1, REP) would make it execute a function called CaptureTeam1 whenever REP team captures a CP. If you want to do this, you'll need to register CaptureTeam1 as a function like so:

Code: Select all

function CaptureTeam1()
    -- do stuff, this is where you'd put your KillObject call
end

You'd place that code *after* (not inside) ScriptPostLoad.

Alternatively, you'd register the event callback like so:

Code: Select all

OnFinishCaptureTeam(
    function(post)
        -- do stuff, this is where you'd put your KillObject call
    end,
 REP
 )

This still doesn`t work for me, are you sure it`s even possible to do this? Everything I`ve tried so far causes errors.

Hidden/Spoiler:

[code]

OnEnterRegion(

    function(region, character)

   if not GetCharacterTeam(character) and GetCharacterTeam(character) == REP then

        Aumbush("ambushregion", "ambushpath", 8, 5)

    end,

 "ambushregion"

 )

 end[/code]

Anyway, that

Code: Select all

OnFinishCaptureTeam(
    function(post)
        KillObject("cp4")
    end,
 REP
 )

thing WORKS! 1 further question, am I able to decide which CP triggers the event I put into it? Because right now with this code, if the Republic captures ANY CP, cp4 will go away, am I able to add in somewhere a certain CP that will trigger CP4 to be "killed"?

The core of my wave-based combat system for my Europa map relies on this very method, so yes, I am 200% positive that this works. You just don't seem to be very familiar with how logic and control structures work within programming, which is totally understandable, everyone starts out not knowing. What you need to do is *learn how these things work* though. Like, seriously, you'll get nowhere unless you do. We can't keep writing all your code for you.

With that said, here's the code I've corrected and written for you. :u

Code: Select all

OnEnterRegion(
    function(region, character) -- this is a function
        if not GetCharacterTeam(character) and GetCharacterTeam(character) == REP then -- this is an if-statement
            Ambush("ambushregion", "ambushpath", 8, 5)
        end -- this is what closes the if-statement
    end, -- this is what closes the function
"ambushregion"
)

Sure. Use GetEntityName with `post` as the argument (passed as the parameter from OnEnterRegion) like so:

Code: Select all

OnFinishCaptureTeam(
    function(post)
        if GetEntityName(post) == "cpname" then
            KillObject("cp4")
        end
    end,
REP
)
