Need help to make little random time setunitpos"up" and "down" for roof snipers

[sknam 2]

Hello guys,

 

In the mission Editor, I often put enemy sniper or rpg on roof of buildings, 

Unfortunately they are always fast detected and killed before to be a real menace.

 

I use this dostop true or disable ai move and I also use setunitpos to select the stance.

If I Iet the vanilla ai system, they just go prone when the detect enemy, and can’t fire through the window or from the roof…

 

I would like to make a little scrips lunched on the AI initialization field, or from a trigger to make an ambush like situation to make my AI switch from down to middle just a little time to firing and hide again for a certain time.

 

 

I was thinking to something like this:  (sorry I am not aware about the syntax)

 

 

 

_myunit setunitpos “down†         

 

Sleep random [ 30, 50]      <- Wait random time from 30 to 50 sec

                                                                                                                                                                                                 

_myunit setunitpos “middle†  

 

Sleep random [ 5, 10]     (the time to select a target and dofire, and hide again)

 

#loop

 

 

 

I am sure that if it works it can add a lot immersion in hostile zone.

 

Please if someone can help me in syntax for the script and for the initialization to run an maybe add a variable in the timing…

 

Thanks for reading.

Cheers

Thank you Evil Organ,

This very close what I am looking for! 

Thank you.

 

 

In JBoy script you can see this:

 

 

// *****************************************************

// ** JBOY_UpDown.sqf

// ** by JohnnyBoy

// ** AI will toggle between two stances with a delay between.  Good for defenders to duck behind walls or windows, then pop back up.

// **  Call:  null = [dude, ["Up","Middle"]] execVM "JBOY\JBOY_UpDown.sqf";

// ** To start with an eventhandler, put this in unit's init:

// this addeventhandler ["FiredNear",{ [_this select 0, ["Up","Middle"]] execVM "JBOY\JBOY_UpDown.sqf";}];

// this addeventhandler ["FiredNear",{ [_this select 0, ["Middle","Down"]] execVM "JBOY\JBOY_UpDown.sqf";}];

//

// *****************************************************

if (!isServer)  exitwith {};

//  Parameters:

_dude = _this select 0;   

_stances = _this select 1;

 

_dude removeAllEventHandlers "FiredNear";

while {alive _dude} do

{

    if ((unitpos _dude) == (_stances select 0)) then

    {

        _dude setUnitPos (_stances select 1);

    } else

    {

        _dude setUnitPos (_stances select 0);

    };

    sleep (1 + (random 15));

};

 

 

 

with this scrips the middle and up postion are random from 1 to 16 second and same for the down position right?

 

how I can modify the timing if I want the Unit is down 50 sec and middle only 5sec ?

 

regards

Try this:

_dude removeAllEventHandlers "FiredNear";
while {alive _dude} do
{
    if ((unitpos _dude) == "MIDDLE") then
    {
        _dude setUnitPos "DOWN";
        sleep 50;
    } else
    {
        _dude setUnitPos "MIDDLE";
        sleep 5;
    };
};

Thank you Johnnyboy,

 

It works!

now I understood how to have the perfect time control.

_dude removeAllEventHandlers "FiredNear";

{
    if ((unitpos _dude) == "MIDDLE") then
    {
        _dude setUnitPos "DOWN";
        sleep (20 + (random 30));
    } else
    {
        _dude setUnitPos "MIDDLE";
        sleep (4 + (random 4));
    };
};

I understand that the script works with " addeventhandler ["FiredNear" "

 

If I want to control when to lunch the script, like from a trigger for expample

 

I have a patrol in a street and when they entrer in the trigger: the snipers crouch and fire.

 

Do you know what syntax I must use to lunch the script?

 

regards

[mySniper, ["Middle","Down"]] execVM "JBOY\JBOY_UpDown.sqf";

Put that in your trigger, and change "mySniper" to whatever you have named your sniper unit.

 

You might need to put "dummy=" at the beginning of this line like this:

dummy=[mySniper, ["Middle","Down"]] execVM "JBOY\JBOY_UpDown.sqf";

One of the above should work for you.

Oh JBoy !

It works, thx mate!

 

is it possible to command several snipers at the same time like this ?

 

dummy=[mySniper,mySniper3,mySniper4,mySniper5,mySniper6 ["Middle","Down"]] execVM "JBOY\JBOY_UpDown.sqf";

 

B) 

[johnnyboy 3741]

{dummy=[_x, ["Middle","Down"]] execVM "JBOY\JBOY_UpDown.sqf";} foreach [mySniper,mySniper3,mySniper4,mySniper5,mySniper6];

That should do it.  Glad I could help. :)

 

Don't forget to put some chickens in your mission.  Everyone knows that a good sniper mission needs chickens.

Yes, 

it works, 

thank you very much Jboy !

:)  :)
