Count the blessed units

[colonel_klink 0]

Not much hair left to pull out now!

Scenario:

Helo (player) finds liferaft with several wretched souls on board.

Problem 1:

How to determine how many of these souls are on the liferaft?

Problem 2:

How to get them on board the hovering chopper? (Getting the driver off is no problem, but rescuing the others is a problem)

Any suggestions?

Probably of no use to you but the ComRef list a few count commands.

count array

unit countEnemy array

unit countFriendly array

side countSide array

typeName countType array

unit countUnknown array

Klink -

Are the peeps on the life-raft 'crew' (ie in cargo proxy

positions), or just standing on it? If it's the former, there's a

crew _unit function that returns an array, IIRC. If it's the

latter, I think you'll need to get 'trigger-happy'.

@Footmunch

They are cargo positions.. Funny how I dragged right trough the comref and didn't see the crew statement. Was looking for cargo

@Scud

tried the count array but couldn't get it to work. The others seem to only work with triggers.

Tahnks fellas.. Will try the crew statement and if it works the fishing boats are closer to re release.

Ok.

_crew = crew _raft gives me the names of the crew i.e Black:1, Black:2 etc etc.

I tried this to get the number of the crew:

_crew = count[crew _raft] gives me just 1

Hmm must be an easy way of doing this

[Scud 0]

If it gives you the names I assume in an array

then can't you use the count array to give you the number in the boat.

By the wat I know nothing of what I am talking about

[colonel_klink 0]

Yep Scud you are correct:

.. an update:

This gives you the units in the vehicle by name

_ArraySouls = crew _NearestBoat

And this ..finally.. gives me the number of units

_newNum = count _arraysouls

Next bit will be defining them as a group and getting them on board the chopper.

if you want to count how many of them are blessed, you can use the second type of count function:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">"(damage _x)>0" count (crew _raft)

A very good function in your case is forEach:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">{_x moveInCargo _heli; _x assignAsCargo _heli} forEach (crew _raft)

this way you don't have to change the groups of the people.

If you want an array of all the blessed people, also use forEach:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_blessed = []

{if ((damage _x)>0) then {_blessed=_blessed+[_x]}} forEach (crew _raft)

Good stuff Hardrock, I had fun in the past trying to do what Klink is doing also

[colonel_klink 0]

Thanks Hardrock, I will try those out. I'm thinking however I will need getout and unassign functions.

[hardrock 1]

You're right, I forgot that before.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">{_x action ["getout",_raft]; unassignVehicle _x; _x moveInCargo _heli; _x assignAsCargo _heli} forEach (crew _raft)

Touche Hardrock.. as I was typing you beat me to it

Here they are after being rescued:

I'm placing a global variable so that once they are on board it loads a script that will give me a command to unload them when I land.

I'm placing a global variable so that once they are on board it loads a script that will give me a command to unload them when I land.

Perhaps easier to do it via the condition variable? Something

like:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

condition = "count (crew _this) > 2 && (getpos _this select 2) < 30"

where the '>2' means more than pilot and co-pilot. Sorry, just

my own aversion to globals (from my C++ background).

Oh, and

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

count [crew _raft]

returns 1, because the square brackets create a new array,

the first entry of which is the crew array. So, the count works

on the 'outer' array, rather than the 'inner'.

[colonel_klink 0]

Yeah I might use something like that, Footmunch

Code Sample :

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

condition = "count (crew _this) > 2 && (getpos _this select 2) < 30"

And even instigate it with a user action that comes up when the chopper speed is less than say 2 and the height is less than 5. "Passengers get out"

Great fun this experimenting

[hardrock 1]

But I would rather use:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">condition = "count ((crew _this)-[driver _this]-[gunner _this]) > 0 && (getpos _this select 2) < 5 && (speed _this) > 2"

since otherwise you won't get the option if you've got no co-pilot but only one soldier in the cargo.
