A more elegant wat to do - random

[Joe98 92]

Place a box on the map and name it box1

Place 9 markers on the map. Group the box with the markers.

Every time the mission starts, the box will start at one of 10 places selected at random (its original location or one of the 9 markers).

 

　

I would like to do this in a more elegant way avoiding those confusing lines all over the map. For example:

 

Place 10 markers on the map and name them marker0 – marker9

Then, in the init of box1, type:

box1 setpos getpos marker(select a number at random from 0 to 9);

 

 

I went to the wiki and found this:

 

https://community.bistudio.com/wiki/random

 

As a result I tried this command in the init of box1

 

_nRumber  =  floor  random  10;  box1  setpos  getpos  marker(_rNumber);

　

It does not work.  Any suggestions?.

box1 setPos (getMarkerPos format ["marker_%1",floor(random 10)];);

Try this untested piece of code in the init line:

_rNumber = floor random 10; this setPos (getMarkerPos format ["marker%1", _rNumber]);

This should also work (and is a bit shorter than the previous answers):

this setPos getMarkerPos ("marker" + str floor(random(10)));

I prefer short comands in init-fields.

createvehicle can do this on it's own.

 

box1 createvehicle ["box1classname", markerpos "marker_0", "marker_1",["marker_2", "marker_3", "marker_4", "marker_5", "marker_6", "marker_7", "marker_8", "marker_9"],0,"NONE"];

The favourite ones I use mostly are:

 

 

For Integers:

rndNum = round(random 10);

For Strings in Array (Got a bit cheeky here ;) ):

player addAction ["Am I good, ArmA?", {rndStr = ["are fucking amazing!", "are a pro!", "are good.", "are not bad.", "are bad.", "are terrible.", "fucking suck!", "are shit at this game."] call BIS_fnc_SelectRandom; hint format ["You %1", rndStr]}];

I never tried the below for myself really, but it is another loop method I found:

rndNum = round(random 10);
switch (rndNum) do {
	case 0: {};
	case 1: {};
	case 3: {};
	case 4: {};
	case 5: {};
	case 6: {};
	case 7: {};
	case 8: {};
	case 9: {};
	case 10: {};
};

Place a box on the map and name it box1

Place 9 markers on the map. Group the box with the markers.

 

How do you do that ? Everytime I'm clicking on the "group" or "chain" icon, all markers are disapearing in the editor.

Yes, you have to remember where the marker is before grouping it.

Or simply make it of a visible type, link them all, then make them empty again :).

Nope because when you select the 'group' menu (f2), all markers are hidden.

And that's what I get for trying to answer posts too soon after waking up :p, lol.

Thx !! I was not aware of this feature.

I just create the marker close by then move it once grouped with the unit.

[Joe98 92]

this setPos getMarkerPos ("marker" + str floor(random(10)));

This is the best and I confirm that it works beautifully thank you!

Agreed. Out of all the solutions, it's the sexiest.

For Integers:

rndNum = round(random 10);

This one is not the best. Numbers 1 and 10 has only half the chance of being selected compared to 2..9, and 10 was not supposed to be selected either. Better to use floor than round to get a value in the span 0..9:

rndNum = floor random 10;

[barbolani 198]

I allways had some doubt about the floor random method.

 

In this case. What if floor random 10 returns 10?

 

I mean: you have "Marker0","marker1"..."Matrker9" so, floor random 10 will be 0 to 9 in 99,999999% of times.

 

But what if your mission is making random calls millions of times per session? That will happen!

 

Just a thought...

random 10 will never return 10. It's between 0>= x <10

Oh, good thanks!
