Opening Gates Using Scripts

[Alex]

Hey All, I Am Making A Mission Using  The FDF Mod And My Journey Takes Me To A Gate In Maldevic, How Do I Get It So That As The Truck, (AI Controlled) Rolls Up To The Gate It Stops And The Guard At The Gate Opens The Gate?
Thanks,
Alex

Assuming that gate is capable of opening, it will be something like this:   group the trigger to the truck for new activation box options.

Activation box:  vehicle present
On Activation:   gate1 animate ["doors1", 1]

If you want it to look better you could add commmands for the guard to walk over to the gate and do a playMove animation.    Also you many need commands to control the truck stopping and starting again:  it might just be easier to open the gate far enough ahead so he doesn't have to stop.   Remember to close the gate after him.

Sorry, Can You Go Step By Step Plz?

What Macca there forgot is that you cannot name the gates in a map as they are placed there when the island was made...
So you would need to use the command object and the gate's ID number instead (attained via using the 'show IDs' button in the mission editor)...

Unfortunately, things are not as simple as that with Maldevic...
A bug in Visitor (if I remmeber correctly) screwed up the object IDs in Maldevic so you will need a more complicated way of opening the gate...

I explain the opening method here, Macca can explain the rest as he does so much better job in it than I would

First, create a game logic near the gate and name it to something like gate_keeper_1 or something (can be what you want it to be...)
then, in the trigger which Macca already described above use this instead:
(nearestObject [gate_keeper_1,"FDFrajapuomi"]) animate ["keppi",1]

[macguba]

The first thing is to make the gate open.    

Check the commmand reference and learn about the commands nearestObject and animate before doing anything else.

Now make a new test mission.   Place the player unit near the gate you want to open.    Follow HateR_Kint's advice and place a gamelogic right on top of the gate.    Name it gate_keeper_1.

Now create a trigger like this:-

Area:   50 x 50
Activation box:  whatever
Countdown:    3       3      3
Condition:   true
On activation:     (nearestObject [gate_keeper_1,"FDFrajapuomi"]) animate ["keppi",1]

(I'm not familiar with this island but I presume we know that FDFrajapuomi is a gate that can open and keppi is the magic spell that opens it.)

Right, now test the mission.   Look at the gate.   3 seconds after the mission starts the gate should open.

Lets assume that works.

Now create a truck with driver, say 200m away.   Give him a move waypoint just in front of the gate.      Now move the trigger over the gate area:  make it smaller, say 10x10 - you'll have to experiment to get the right size.      Hit F2 and drag and drop a blue line from the trigger to the truck.    Open the trigger and edit it like this:-

Area:   10x10
Activation box:    Vehicle present
Countdown:    3       3      3
Condition:   this
On activation:     (nearestObject [gate_keeper_1,"FDFrajapuomi"]) animate ["keppi",1]

Now watch the truck drive up to the gate and stop:  watch the gate open.

Now, back to the mission editor and give the truck a second move waypoint, 200m past the gate.     Open his first waypoint and change the timeout fields to 10  10   10.   Test again:  this time he should wait for the gate to open, then drive through.

Now go back to the trigger.     Place it very close to the gate, so that the area on each side of the gate is about the same.     Add this to the trigger:-

On Deactivation:    (nearestObject [gate_keeper_1,"FDFrajapuomi"]) animate ["keppi",0]

Now add a sentry standing beside the gate.     Preview the mission and admire your handiwork.

I just hope it works.  

These are very detailed instructions so I've probably forgotten something.    Follow them carefully, but at each point think about what you are doing and make sure you understand it.    You may have to change some of the instructions to make it work:  experiment!

We'll worry about making the guard do stuff later.

FDFrajapuomi is a gate that can open and keppi is the magic spell that opens it.

'keppi' is actually the animated arm on the gate... The magic spell opening it is 1, and closing it 0... (*picks a nit*)

('keppi' translates to english as 'stick'... like somebody cared )

IT WORKS!!! THANKS GUYS! How Can I Get An Empty Vehicle To Explode As Soon As The Game Starts??

[macguba]

  Good!

Set its health slider to 0.

[Alex]

Lol! I've Tried!

[THobson]

Have you tried

this setdammage 1

in the vehicle's initialisation field?

[Alex]

Yeah.... I've Tried But With FDF Mod When Vehicles Are Destroyed They Burst Into Flames, But On Set Dammage 1 And Health slider to 0 It Doesn't.... :Edit, I Wan't it To Catch Fire.....

[C0LDSt33L]

setdammage 4? get a hidden guy to shoot it? fire script? a combination of these? One might work.  

[Alex]

Where Would Be A Good Fire Script Mate?

[THobson]

Failing any of these try camcreate a shell or two at the vehicle's location

[THobson]

Try something like this.

Put

this exec"VehicleSmoke.sqs"

in the vehicle's init field

[C0LDSt33L]

Ivor Drukov does good fire too. Enclosed is the script with example.

[THobson]

That is neat!!  And subtle, imagine having parts of a vehicle burning.  Fantastic.

[Alex]

I Tried The Example Mission  ;D GREAT STUFF!
What Would The Flame Position Be For A BRDM Shape Vehicle?
It Is Currently,
relative position of fire to vehicle
_ox=(_this select 1) select 0
_oy=(_this select 1) select 1
_h=(_this select 1) select 2
What Should It Be?

[C0LDSt33L]

Hmmmm you may have to experiment. Try adding or subtacting the values:

_ox=((_this select 1) select 0) + 10

or _oy=((_this select 1) select 0) - 1

(notice the extra brackets) to move the flame. It will be trail and error getting it in the right place i'm afraid.

[Alex]

Do I Just Change The "10" And "1" Till I Get It?

[Alex]

Also, Any Other Fire And Smoke Or Explosion Scripts Anywhere That We Can Look At?

[C0LDSt33L]

Yeah, just change the values of the "1" and "10". Don't forget you can change the height of the flames too with

_h=((_this select 1) select 2) + whatever

If you're after other scripts you could head down to the editors depot and look at the scripts and do a seach for fire. There should be a number of relivent ones.

[C0LDSt33L]

I did a search for you the results page is http://www.ofpec.com/editors/browse.php?browseon=&browsewhat=2&category=2&subcategory=2_-1&numreturn=25&displayformat=0&ofpv=1&searchstring=fire&searchwhat=1&searchlevel=0&searchopts=

There's bound to be alternative fire scripts there.

[Alex]

I Kind Of Need One Without The Smoke Going Too High......
But Thanks A Lot Coldsteel!
