Random Insertion Point

[plugger 0]

Goodaye,

I have four empty markers on the map in a SP mission. I'm running a simple init.sqf script (below) at the start in order that one of the four markers is selected as the insertion point for the Player Recon group.

The script runs without errors but my Player group always starts in the one spot, i.e no randomness. I've tried different approaches with no luck and I'd appreciate any guidance that you might have. I'm also just starting out with the scripting and I realise that I may have made some fundamental error of logic.

Here's my script.

//init sqf

//provides a random start insertion pt between one of 4 possibilities

//on the map are four empty markers named start 1 to 4

//get positions of the four markers

_pos1 = getMarkerPos "Start 1";

_pos2 = getMarkerPos "Start 2";

_pos3 = getMarkerPos "Start 3";

_pos4 = getMarkerPos "Start 4";

_rnumber = random 3;

_array = [ _pos1, _pos2, _pos3, _pos4];

//create insertion marker and place at one of four random positions

_markerobj = createMarker["insert",(_array select _rnumber)];

_markerobj setMarkerShape "ICON";

"insert" setMarkerType "START";

Cheers,

mhh.. interesting..

some languages need to initialize the random number generator first or they would get the same sequence of numbers everytime.

don't know if it'll help any but i would try adding a "sleep (random 0.1);" before and see if that makes any difference...

edit: not sure but does random 3 give all 4 the same chance of being chosen? i would use "(random 4) - 0.5;" to be absolutely equal.

biki says:

Quote[/b] ]-0.5 rounds up to 0

-0.5 <= index <= 0.5 rounds to 0

0.5 rounds down to 0

0.5 < index < 1.5 rounds to 1

1.5 rounds up to 2

1.5 <= index <= 2.5 rounds to 2

2.5 rounds down to 2

2.5 < index < 3.5 rounds to 3

Could it be that the select command doesn't recognize broken numbers? You might have to make it:

_rnumber = random 4;

(_array select (floor _rnumber))

nope, it should work. at least according to what the biki says.

do you change the group's position in the leader's ini line to the starting marker or did you forget to add it in the ini.sqs? cause simply selecting a random pos and adding a marker, won't move your group to that position. try <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">{_x setpos (_array select _rnumber)} foreach units this or change <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">this to the group's name (of course you have to name the group first by adding <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">groupname = group this to any units ini line. not sure if that will work with an ini.sq(f;s).

ok i made it an ini.sqs (not sqf) but it works. the group is named sfrec. it actually is random, but it often sets you in the same spot.

here it is: test.intro - offline

you have 48 hours to download. after that i'll delete it of my uni-server.

You don't need a script for that.

Create 4 empty markers and group (F2) one each of them with the leader of the group.

It's tricky cos you can't see the markers anymore when you press F2 to group them. Hover your mouse over one a marker until you see his name. Hold the LMB and drag a blue line between the marker and the unit and do this for each marker.

The (whole) group will start random on one of the 4 markerpositions.

are marker names with spaces in allowed?

Goodaye,

Thanks for the help. The idea (blanco) without the script worked fine.

I couldn't access the script that Asuriel provided the link to but I appreciated the advise.
