spawn random number of units from a group

[clydefrog 3]

Hi, if I have a group being spawned like the following:

       _pedgrp = createGroup west;								// create and spawn pedestrian group

       _unit1 = _pedgrp createUnit ["C_man_1_1_F", [_spawnPos select 0,_spawnPos select 1,1], [], 26, "NONE"];
       _unit2 = _pedgrp createUnit ["C_man_polo_1_F", [_spawnPos select 0,_spawnPos select 1,2], [], 26, "NONE"];
       _unit3 = _pedgrp createUnit ["C_man_1", [_spawnPos select 0,_spawnPos select 1,3], [], 26, "NONE"];
_unit4 = _pedgrp createUnit ["C_man_polo_6_F", [_spawnPos select 0,_spawnPos select 1,4], [], 26, "NONE"];

how can I make the script only select a random amount of them each time the script is run? So in this case a maximum of 4 and minimum of 1?

do you mean something like this or have i read that wrong....

_rnd = ceil(random 5);
_pedgrp = createGroup west;
for [{_i=1}, {_i<_rnd},{_i = _i +1}] do

{

  _soldier = ["C_man_1_1_F","C_man_polo_6_F","C_man_1","C_man_polo_1_F"] call BIS_fnc_selectRandom;
_unit1 = _pedgrp createUnit [_soldier , [_spawnPos select 0,_spawnPos select 1,_i], [], 26, "NONE"];

};

If that's picking a random classname no. I mean selecting a random amount of units from the group to spawn. So if the group created is 4 soldiers then randomly spawn a number between 1 and 4.

[mikie boy 18]

the above randomly spawns between 1 and 4 soldiers with different classes

Oh great, do you mind explaining a bit how that's working?

I can see it is assigning _i as a random number below 5 and then spawning that many units, but I'm unsure about a couple of things, including where _i is in the createUnit array.

Thanks

look at the tutorial i made - the 'for loop' - should clear up what _i is doing there. long story short - _i is just representing the count form 0 upwards - but placing _i within the loop it represents whatever 0 -4 number it is currently. So each time it goes round it increments by 1 until it reaches whatever the maximum number is defined by _rnd.

Sorry if i havent been clear

Yeah I've read it and I just had another look before asking you but still couldn't make full sense of it ( I understand it in your tutorial but didn't this way with the random number).

2 things, how come the _i goes where it does in that array? I thought that was to do with position. And also sometimes it is not spawning any units at all.

its probably defining 0 in the random variable.

basically you have used _spawnPos select 1,1 - i have put _i in where _spawnPos select 1,_i - this is because each time the loop goes round _i = 1, then 2, then 3, then 4. Thus it mirrors the 1,4 you wanted. If i didnt put _i there it would always be the number u put in the line.

if the loop only goes round three times then the first will be 1 and the last will be 3. that any better?

I don't actually know what the number at the end of that line [_spawnPos select 0,_spawnPos select 1,1] does. They are 1 to 4 in my first example just because I was trying to see what it actually did, I thought it might be altitude or something, this is why I'm confused why the _i goes there. I still don't know now what it does.

Sorry for not understanding this, maybe by putting those 1 - 4 after each _spawnPos select 0,_spawnPos select 1 I have confused you to what I want it to do as well. I just want to be able to create this group multiple times by calling the script multiple times, but each time the script is called it spawns a random amount of units from the group, with a maximum amount possible of about 4 or 5 and a minimum amount possible of 1.

_spawnPos select 0,_spawnPos select 1,Z [x,y,Z] position of whatever _spawnpos is - height basically...

_rnd = ceil(random 5);

_pedgrp = createGroup west;

for [{_i=1}, {_i<(_rnd + 1)},{_i = _i +1}] do

{

  _soldier = ["C_man_1_1_F","C_man_polo_6_F","C_man_1","C_man_polo_1_F"] call BIS_fnc_selectRandom;
_unit1 = _pedgrp createUnit [_soldier , [_spawnPos select 0,_spawnPos select 1,0], [], 26, "NONE"];

};

That should do it, +1 to the random number - so never 0. 1- 5 units per group should spawn everytime you call this script. I've set the Z co-ordinate to 0.

Works perfect, thanks Mikie.
