Random Channels for Object Rezzing

I'm currently working on a placemat which rezzes dishes on top of the placemat, as chosen through a blue dialog menu.

Well, I've gotten everything working and rezzing perfectly when only one placemat is rezzed within 10m. When I have two or more placemats on a table, the first placemat rezzed works normally. However, when choosing a dish from the second placemat's menu, the first placemat pops up it's own menu behind the second's, and then both placemats rez the same dish.

I've tried different ways of giving each individual placemat it's own channel through llFrand, but the same problems always occurs.

Can anyone give me any insight?

Generate the random number in state_entry and assign it as the channel. This way each placemat will have a different channel.

If you are still having a problem then either post the whole script here or at least the part with state_entry and we will help.

Really? That is, you can touch the "first" placemat and you get only the dialog for that one, not the second? But if you touch the second one, you get both dialogs? If so, what makes one of these the "first"? (First rezzed? First touched? ... not that I have a ready explanation, in any case.)

By first I mean the first rezzed.

I tried adding an llFrand equation to state_entry, to no avail - here's the script if anyone can look it over.

*NOTE: With this change to the script, my avatar speaks the choices into the world as well, even though the channel isn't 0.

Do what Jesse said.

The error in your first script is that n is 0. llFrand is really just returning a float value from 0 to 1, you then convert it to a integer. So over 99% of the time it will be 0.
So the channel that you are getting is 500001. Another fix would be to change the integer n; line to integer n=10000;

I forgot to mention that you did a nice job for a new lsl scripter and that it is a pretty creative idea.

Thank you Jesse! I have a bit of practice in Java programming from high school, but it's been ages.

Ok, I've tried both ways, and it's still giving me that same problem. Which ever placemat I touch second spawns both mat's menu's.

Could it be something in the rest of the coding?

you are removing the listen with a timer. so why not generate a new channel on touch rather than only once in the state entry? i do that for anything i use menus for. and while we're on the random channel topic, what do you do with the items that are rezzed as far as removing them to rez a new one? i like to generate a random channel and pass it to the object thru the param integer, then when it comes time to rezz a new item, it would first tell it to die on that channel and then change the channel before rezzing the new item with a new channel.

Right now, I have a temp-rezzing script inside the dishes that kills them after a minute, or whatever the time is on that server.

How would I pass the channel on to the rezzed object? Could I get an example if possible? Now that I think about it, having the objects destruct before a new one rezzes might be a better option. Would that work with a "Clear All" button on my menu as well?

alrighty, i cleaned up the current script some, and added the prim channel i mentioned before. and the script to drop into the items will listen for the word die, but also change it's position on rez. also i added llGetRot() to the rez command, you had it at zero rotation before which wouldn't really look right if the placemat is rotated. as for the clear all, it will only work for each placemat and the item on top of it



and then drop this one into each item and change the offset

Thank You! The placemats work like a charm!
