Trigger activation

[RAMBO 0]

I need to know a simple thing which cannot come up to my mind.

How can I activate a trigger when 2 vehicles get in a trigger area.

THANKS.

That should work.

If not use this:

</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">unit1 in thislist AND unit2 in thislist<span id='postcolor'>

I have just herd that using the first example may be quicker.

Hi Rambo,

just wanna add some info in here for your

better understanding of those condition fields

in triggers.

By default, the setting in a trigger's condition field

is: THIS

What does it mean? - Well it means the trigger becomes

active, as soon as the activation settings above the

condition field are true.

This could be: West present, or East not present, countdown,

etc. However, if you want to get in use of the trigger's

activation settings, you need a condition: THIS

OK, then we have the condition: TRUE

True means, the required condition of this trigger will be true

as soon as the mission starts. The trigger gets activated

when the mission starts (such triggers are often used as

initialization triggers, or to play music, text-messages etc.)

You can use a variable instead of TRUE, and start the mission,

by setting this variable to false.

Usually, a variable (not numeric) is FALSE at mission start.

You can use another trigger, waypoint, script to set this

variable to TRUE.

Example:

trigger A - condition field: gogo

:note - gogo is a variable, and the trigger expects this variable

to be true, so that it gets activated.

1 AI unit with 2 waypoints, or more/less (at least one wp)

into any waypoint's activation field, you type: gogo=true

Once the unit has reached the waypoint with gogo=true,

trigger A gets activated.

Also you can mix conditions together, by using the AND

statement.

For example: You want a trigger to wait for a specific side (let's say WEST) inside it's area, and the variable gogo should

be true aswell.

trigger A - activation: West/present

condition field: this AND gogo

:note - this expects the settings West/present to be filled,

while gogo you've seen above, how to make it true.

Also you can use numeric variables to activate triggers

(this way, you can use a variable multiple times in a mission).

Let's say we want to have 3 triggers, and we let them get

activated by the same variable, but with different conditions.

trigger A - condition field: gogo == 1

trigger B - condition field: gogo == 2

trigger C - condition field: gogo == 3

trigger D - condition field: true

activation field: gogo=0

:note this initializes the variable gogo as a numeric variable

with a value of 0 - usually numeric variables will start with

a value of 0, but this is the clean way, how it should be

done.

Now create a unit, + 3 waypoints. In the 1st waypoints

activation field: gogo=1

or: gogo=gogo+1

:note - if you use: gogo=1, you do the value change hardcoded, this means you don't care, what value the variable

actually owns, you just set it to 1

While using gogo=gogo+1 let you be more creative, because

you could use always the same command (probably the same

trigger), to increase the value of the variable gogo.

If gogo is actually at the value 0, and you say gogo=gogo+1,

it will increase to the value 1. If gogo is 1, and you use the

same command, it will increase to 2.

:hint - you could use a patrol, walking a cycle, and everytime

it passes the 2nd waypoint, you could say: gogo=gogo+1

!! Only one thing, to take care of: don't mix numeric and

boolean variables (boolean is the name of the TRUE/FALSE

variables).

What i mean is, don't use the same variable with a value

and with a true/false in the same mission. This will only cause

some generic error in expression, or whatever error message.

hope it wasn't to confusing and it makes some light into

darkness

Greetings all...

How can I set a trigger to fire when all units of a group (the player group) are within the trigger radius? In other words, the trigger must not fire unless all group members are within the radius.

It should be noted that although there can be up to 6 members in my group (West1, West2, ......, West6), the trigger still needs to fire if for example there are only 3 players and the remaining 3 units (West4 thru West6) have been disabled (by disabling AI).

Any help is greatly appreciated.

Kind Regards,

RedRaider

Soso, you're talking about multiplayer.

OK, excepting you have a whole playable squad, you

can never get sure, that the group leader won't be disabled

from the lobby aswell. So everything you want to use out

of his init-field, or grouping (F2) to a trigger could become useless.

My first hint is then:

Create a trigger with an area, covering the whole squad (only

that squad).

Activation: side of your squad/present/once

condition: this

onactivation:

myleader = this select 0; mygroup = group myleader

Then create another trigger (the one you were asking for);

activation: anybody/present

condition: this AND "_x in thislist" count (units mygroup) == count (units mygroup)

This trigger will only become activated, once the whole

team is inside the trigger's area.
