Delaying the Radio Call

[froggyluv 2130]

How do you disable a radiotrigger ie. Radio Alpha, until another unit is in his set position. I'm trying to give the player access to the call only after a sniper is in a set position but when i place the radio trigger over the waiting position and add "sniper in this list" it actually ctd's. Without it, the player has access to the radio command right off the bat which could throw the whole mission off. Sniper is the name of the unit before anyone asks :D

You need two triggers, one for the radio and the other for the checking of the sniper. Name the second trigger "sniper_trigger" and type the following in the radio trigger, in the condition line :

this and (sniper in sniper_trigger list)

[froggyluv 2130]

Interesting, but I get an error that I'm missing an ')' right before the 'list'.

[kylania 567]

Radio triggers with conditions more than "this" crash the client, saw that in another post. :)

You could just create the Radio trigger on the fly once conditions are correct as well.

[froggyluv 2130]

Sorry, but could you walk me thru that a little - that is creating another trigger on the fly?

Yep i made an inversion :

this and (sniper in list sniper_trigger)

[froggyluv 2130]

That still freezes up the game if I test it and try to call the radio early.

I did as you said, gave the Sniper now named "alpha", his waypoint rigger named 'sniper_trigger'. The radio trigger which is global I gave the condition:

this and (alpha in list sniper_trigger)

and this trigger is also a switch as the radio is telling Alpha to proceed but alas, it freezes the game if called early.

Edit- it works fine if Alpha is actually within his waypoint trigger but crashes if he is not :confused:

So as kylania said, there's a bug with the radio triggers condition line... you must then create a radio trigger when the first trigger is activated. It's not that hard. Just some "createtrigger" then "settriggeractivation".

[kylania 567]

Sorry, but could you walk me thru that a little - that is creating another trigger on the fly?

There's a few ways of doing this, but here's one.

First make a trigger that will enable the radio. Mine has an OnAct of:

nul = [] execVM "addRadio.sqf";

That calls the addRadio.sqf as shown below:

[color="SeaGreen"]// Create a radio trigger ALPHA, not repeatable called "Activate Radio"[/color]
_radio = createTrigger ["EmptyDetector", [0,0,0]];
_radio setTriggerArea [0, 0, 0, true];
_radio setTriggerActivation ["ALPHA", "PRESENT", false]; [color="SeaGreen"]// set to true if repeating.[/color]
_radio setTriggerText "Activate Radio"; [color="SeaGreen"]// title for the radio option.[/color]
_radio setTriggerStatements ["this", "nul = [] execVM ""myRadioAction.sqf""", ""];

[color="SeaGreen"]// Let the player know the radio is now available.[/color]
hint "Radio option available!";

That will create a Alpha Radio trigger in the middle of nowhere which is displayed as "Activate Radio" and when triggered will run whatever script you want, in this case one called myRadioAction.sqf as shown below:

hint "You've activated your radio!";

So, one pre-placed trigger to open the Radio option. One script called by that pre-placed trigger to create a radio one on the fly, and a second script to do whatever the radio is supposed to.

Thanks Kylania. I can sorta of follow and your script does work but I don't know how to simply tell 'Alpha' to switch to it's next waypoint thru scripting. I've been depending on those 'switch' triggers too long I guess.

Is there no easier way then to write a waypoint script in your "Myradioaction.sqf"?

[kylania 567]

The ALPHA in the above example is a code word for "Radio Alpha", not a unit name or anything.

I'm a little confused about what you mean by 'switch to it's next waypoint'.

How exactly is this radio option supposed to work in your mission? Ignoring coding, what do you expect to happen or be available to the player?

[froggyluv 2130]

Ok, I've got a Sniper named Alpha, who treks off at the beginning of the mission to establish his sniping position. The player and his team our off to run other errands for a while, but once the PC is ready, he is to radio his Sniper that it's time to get moving. The Sniper was held in a 'Hold' waypoint and the PC has the 'Radio Alpha' command which is a switch trigger attached to the sniper's (also named Alpha, probably bad idea)Hold waypoint. Once called in, the Sniper will then proceed to engage + meet up with player.

So basically I was using the Radio Alpha call to release the sniper from his Hold command. the only problem with that, was that the radio is offered from the start so an unwary player might call him too early.

[kylania 567]

Ok, that's even easier, just need the first script.

Go ahead and setup your waypoint and the HOLD waypoint and put a SWITCH trigger synched to the HOLD waypoint with condition of:

gocode

Setup some trigger that determines when the errands the player is doing is finished, have that call the following script:

_radio = createTrigger ["EmptyDetector", [0,0,0]];
_radio setTriggerArea [0, 0, 0, true];
_radio setTriggerActivation ["ALPHA", "PRESENT", false]; // set to true if repeating.
_radio setTriggerText "Call in sniper"; // title for the radio option.
_radio setTriggerStatements ["this", "gocode = true;", ""];

That will create a radio option that will release the sniper from his HOLD waypoint.

[froggyluv 2130]

Ahhh, thanks that seems to have done it, at least in testing phase :)

I guess I tried something similar as using a variable ie, Gocode = true, in the editor rather than scripts but it just didn't seem to work. Guess thats why it pays to learn scripting.

Thanks again!

Hi Kylania,

I am trying to do something like this in ARMA 2:

- I have a DIALOG with a SPY and, only after this DIALOG and IF this DIALOG Happens (this routine is ready and working with a GAME LOGIC Object and Waypoints for the DIALOG - OFPEC BASIC TUTORIAL DIALOG) I want a RADIO CALL CHARLIE to appears in the RADIO to MOVE SABOTEURS to a CITY.

I can MOVE the SABOTEURS with a RADIO Trigger AND Synchronizing it, but the point is: I don't want this RADIO SIGN ON if something Happened wit the SPY, or the PLAYER did not TALK to the SPY to know about that.

Understood ?

I think it's something near what you told us above. But I don't know where to put this code or how make this work.

Thanks for now !

[kylania 567]

You can "disable" a radio option via this command:

3 setRadioMsg "NULL"

So in the init.sqf you'd use the above code to turn off Radio Charlie then during your dialog you'd turn it back on via:

3 setRadioMsg "Move Saboteurs to the City"

[chicao77 10]

Thanks a LOT Kylania, it worked Very well.

I simply put the first line to the INIT CODE in the PLAYER:

3 setRadioMsg "NULL"

And them put the second in the LAST DIALOG with the SPY Waypoint -> On Act BOX.

3 setRadioMsg "Move Saboteurs to the City"

But, just only to know how, if I want to use the createTrigger command how can I proceed to do that ? Using the SWITCH, GOCODE and the way that you describe above ? Where can I put that CODES ?

I got a demo mission at home which shows how to add a trigger from another trigger, I'll post that tonight.

Hy Kilania !

Can you POST your mission for us ? Thanks a LOT !

[kylania 567]

Doh, totally forgot.. again. I do that a lot. I think, I dunno I forget.

[kylania 567]

Here it is! Sorry for the delay. Radio Alpha and Bravo work from the start. Blow up the car with your SMAW to enable Radio Charlie.

Demo mission

[chicao77 10]

Thanks VERY MUCH FRIEND ! I will take a look this night !
