Using !Alive check to create objectives

[Gunter Severloh]

!Alive Check
Using !Alive in a trigger basically checks to see if the object (name) is alive.
So this can be a soldier, a car, a radio tower, anything that moves, or exists, almost depends as a radio tower is a static object.

How to create objectives using the !Alive check
This is a very simple way to create many objectives in a mission without the need of all sorts of scripts
and extra coding. When i normally use this parameter I like to use it in relation to a marker.

Example on how to use
Heres how this works, below is an example of how to use this :

Killing an enemy officer Example

1. Place a player on the map wherever you want, basically where you want him to start.
2. Place (insert) an enemy officer wherever you want, away from you somewhere that you need to travel too.
3. Give this officer a name, edit the unit and in the variable name box name the officer Ivan
4. Create a trigger under axis A and Axis B at the top make the numbers 0 (zero)
5. Condition !alive ivan
6. On Activation hint "The enemy Officer has been eliminated!"; deleteMarker "ivan1";
7. Create a marker name it: Ivan1 Text: Enemy officer
8. Save, play. Once ingame go to your map you should see a marker that says: Enemy Officer
9. Go to where that marker is on your map, kill the officer and a hint (message) will popup on the screen and say:
   

The enemy Officer has been eliminated!

At the same time the marker on the map will be deleted.
==================
As you can see you can copy this and use it for multiple objectives, for example you can set it up to have a radio
tower as an objective, same concept applies, just give the tower a name, put a marker down, adjust the !alive trigger.

You can use this concept with anything ingame that can be destroyed, makes for a long mission when
your map is dotted with multiple objectives, this is an alternative way to using Tasks.

Just an alternative to the above, the condition could also be:-

Not Alive Ivan

This does exactly the same as:-

!alive Ivan

If you wanted the condition to be the death of 2 officers then simply (2nd officer for this example called Eric)

Not Alive Ivan AND Not Alive Eric

The trigger won't activate until both are dead.

If your going to have an 'and' statement, it is better to put each check into brackets as the game might hickup on them.

(!alive meh) && (!alive dude)

I can put up some other things concerning conditions if you want, such as it being based upon a

count of units inside the trigger area.

Groups
If group is named group1

These will check if there are less than four units remaining in group1.
({alive _x} count units group1) < 4
or
({alive _x} count units group1) == 3

These will check if the whole group1 is dead.
({alive _x} count units group1) < 1
or
({alive _x} count units group1) == 0

[Gunter Severloh]

This trigger condition checks to see if all living memebers of a named group, in this example called Grp1 are in a truck called truck1

{_x in truck1} count units Grp1 == count units Grp1;

To name your group Grp1 put this in the leaders init line

Grp1 = Group this;

Place a truck named truck1 of the same side as you with a move waypoint right in front of it, then other waypoints for the truck to follow once your in it. Then syncronize the 1st move waypoint with the trigger with the condition from the 1st line above. The trigger won't activate (truck wont move) until all the living members of your squad are in it.

Optional - I would also put this line in the init of the truck to make sure it doesn't get detected/destroyed by enemy before you get to it (this stops the truck reacting to enemy and also stops enemy reacting to the truck):-

this setcaptive true

In my experience with Ironfront there is a possibility that at some point during the mission your AI squad mates, if thats what you have, may just stand there and not follow orders anymore, if this occurs you will need to kill that/those disobedient fellow/s brefore you get to the truck or the trigger wont work as its waiting for him etc.
