How to delete an object at random with a script?

[Joe98 92]

I place myself on the map and arrange it so I start at one of 30 places at random.

I place 2 enemy soldiers on the map. They are named

red1 and red2

　

I want the 2 enemy soldiers to start the mission about 200 meters to my north. When the mission starts a script runs and places the 2 soldiers 200 meters to my north as planned.

　

However I want red2 to appear sometimes and not other times. I means I never know how many enemy there are.

So, in the init of red2 I set it so that he appears only 50% of the time

Now, from time to time red2 is deleted. It means the script above stops with an error message:

"object red2 does not exist" or words to that effect.

　

In the meantime if I wish to delete red2 in a script, I can use: deletevehicle red2

So, I am looking for a command along the lines of:

deletevehicle red 2 and do so at random.

 

What is the command for this?

.

I'm not sure I understood the request exactly but you could try,
 

In the init file put,

red1=objNull;

Then something like,

random=[0,1] BIS_fnc_selectRandom;
If (red1 !=objNULL && random ==1) then {deletevehicle red1;};

Have fun!

Yep, wogz187's script seems about right, or you could actually do it the other way around (depending on the structure of your other scripts and calls)..., that is instead of deleting red2 at random, create red2 at random, with pretty much the same effect.

That has been replaced by the engine command https://community.bistudio.com/wiki/selectRandom

nothing will happen unless you call it first

[engima 328]

if (random 100 < 75) then {

    // With a chance of 75%

    deleteVehicle red2;

};

If using the Editor, just set the unit to 50% probably in the probability setting. Just double-click to open the settings. No need to script.

It seems like he knows that, and actually is looking for a way to do it in a script also.

 

Reason unknown though.

 

I need to add that you can check the existance of a variable (or unit) with isNil:

 

if (!isNil ”red2”) then {

    // red2 exists and handling it here will not generate script errors.

};

Yeah, George said you'd make fun of me for using that. He's either super-smart or you're very predictable. 😄

 

I guess it doesn't have to be either or.

@everybody,

Let's be honest though, if I forget to type "call", I probably should stick to the selectRandom method.

 

Thanks, Dedmen.

Thank you to enigma.  This is what I was looking for.  I wrote it like this:

 

if  (random  100  <  50)  then  {deleteVehicle red2 };   // Giving a chance of 50% of being deleted

 

 

[killzone_kid 1333]

deleteVehicle selectRandom [objNull, red2]

will also give you 50/50 chance. Or

call selectRandom [{}, {deleteVehicle red2}]
