Random Command

[Rommel 1]

Has anyone got any idea how to use the random command? What I'm trying to do is get a random out of 12. (for a shooting range) the targets are called t1 - t12.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_num = random 12

picks a random number between 0 and 12 to 3 decimal places

But for your case it might be easier to use something like this

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_targetarray = [t1,t2,t3,t4,t5,t6,t7,t8,t9,t10,t11,t12]

_target = _targetarray select (random 11)

That uses the select command with the random command to pick a random array entry from the _targetarray

thanks mate. Trying it out now...

_target = _targetarray select (random 11)

Err.. I don't think that will work. That would make calls like this:

_targetarray select 8.523

I don't think OFP knows which index to select in such a case. However, with the 'mod' command, you can round numbers (see link). Or, you can use one of these functions:

Actually the select command in OFP does work with remainders of numbers present. It appears to do a standard round before selecting an array index. Perfectly safe, heavily used in some places.

I'd say random 11.49 in that case not 11, but that's the idea.

and what about:

_t = 1 + Random 11

_target = Format["t%1", _t - (_t % 1)]

...i think it's more flexible - no need for arrays

Arrays are only needed if you want to work with objects anyway.
