Synchronizing Channels

Hi ya'll, maybe somebody could give me a push in the right direction here.

I was wondering if there was a way to make a object synchrinize a channel it listens to with a remote unit.

For example 2 RC Cars with two different Remotes rez it press a synch button on a HUD and than it would listen to that given channel.

If this all makes no sense I appologize but it's 12:39 am and im fighting with this Idea the whole day without any result.

Cheers

have the remote rez the RC with a random channel number as the start parameter, retrieve that in the car an use it for the listen

See my problem is that I can't figure out how to make it rez with a random channel. But thanks for the advice that brings me a little closer o my goal

I gotta admit I am a bloddy Beginner with scripting but I try.

You'll need to use the LSL function "llRezObject" to rez the object in the first place, and pass a channel number in as the last parameter to that function. See this page for more info:

But how can I get it so that the channel number is randomly generated each time I rez a new one?? Or do I simply miss the point here

You can generate a random number using llFrand. For example, something like this might do the trick:

integer channel = (integer)(llFrand(1000000) + 1) * -1;

You then store that channel in your rezzing object so it knows which channel to communicate on, and pass it into the llRezObject function.

For random negative channels to use between scripts, I often use a function that looks like this:

integer randomNegativeChannel()
{
   return 0x80000000 | (((integer)llFrand(1<<15)) << 16) | (integer)llFrand(1<<16);
}

That should do a fairly good job of generating a number between -1 and -2^31. You can't simply use one call to llFrand() if you want to take advantage of the whole range because llFrand() only has a resolution of I think 24 bits.
