Howto trigger set off for 2 units?

[TAW_T-Bone 10]

I am looking and reading and can't find it.

i want a trigger to go off when 2 vehicles went through the trigger.

And then as action come up with a text to show to all clients that those 2 vehicles are coming. vehicles are run by players no AI's.

Place a trigger and have in the condition:

{typeOf _x in ["Mytruck","mytruck2"]} count thislist > 0

Have the vehicle types in the list it checks through. You could have lots of different things here aswell, say you named the vehicles in the editor.

{typeOf _x in [Vehicle1, Vehicle2]} count thisList > 0

Basically what it does, is counts how many true statements are returned from that loop.

ie.

If the trigger has a man, a car and a tank in the activation field.

ThisList = [man, car, tank]

and

MrX = man

{_x == MrX} count thistList > 0

Would return 1 as there is 1 unit that is equal to MrX in the array "ThisList".

Hope that helps?

should i leave "this" in the condition cause when i hover over the trigger in the editor it has a ? infront of the line.

I got in condition: {typeOf _x in [tank1, tank2]} count thisList > 0;

I got as action: hint "tanks are moving in"

When i drive both tanks through it doesn't say anything.

The pure trigger-based way, OFP old school :

name your 2 vehicles "vec1" and "vec2"

create 2 triggers.

In condition of 1st trigger :

({(vehicle _x) == vec1} count thislist) > 0

In condition of 2nd trigger :

({(vehicle _x) == vec2} count thislist) > 0

Create a LOGIC

add a Waypoint to your logic, type "AND". Synchronize this waypoint with the 2 triggers above

add another waypoint somewhere away for your LOGIC. Create a 3rd trigger containing the last LOGIC waypoint, group this third trigger with the LOGIC. Go into "effect" tab of the trigger, add some text with the warning you need to print on screen.

tank1 in thislist && tank2 in thislist

on act: hint "tanks coming"

Vehicles are empty at mission start, not sure the simplest way works fine

[shuko 59]

{vehicle _x == tank1 || vehicle _x == tank2} count thislist > 1

That is Rommel's solution :)

Now, second problem : what if both vehicle goes through the trigger, but not at the same time?

[kylania 568]

In that case you'd want 3 triggers probably. One to check if veh1 went through and to set a variable to true, another to check if veh2 went through and to set another variable to true (or add to the first) then a third to check when those variables are true (or the variable is > 1 or something) and trigger whatever you'd wanted to happen.

That's what I did, with a little Logic trick instead of variables

2 triggers, which can set a bool var true, or just do nothing and you use triggerActivated on the 3rd one that shows the message. No need for bunch of game logics, waypoints and sync.

:) Sure, there are tons of ways to do things in A2.

I keep reading there's too much scripting in A2 editor to make it friendly, I just try to propose some new lights on possibilities of the editor ;)

Oops, I came in late to the thread and missed the LOGIC stuff. Good approach, I like offloading stuff to the editor sometimes, though keeping track of it can be a challenge in some cases.

[shuko 59]

Well, it still takes 3 triggers, scripting or no scripting. I'd still rather write:

triggeractivated t1 && triggeractivated t2

than add extra stuff with editor.

It is working perfectly the way Whisper said.

Cheers mate
