how to get prims to communicate with another prim?

[JJ Paragorn]

I want to click a prim and then once it is clicked, I want the prim right beside it to say I can hear you.  Can anyone help?

you need to learn to script.  This prim clicking thing of yours is a fairly simple task requiring a basic knowledge of building and a mere few lines of script

[Rolig Loon]

1. Create a prim.

2. Use your Build/Edit menu and open the Contents tab of the prim.

3. Click New Script.  That will create (tada!) a new script that says "Hello, Avatar!" when you click on the prim.

4. Find the line after touch_start in the script that says llSay(0,"Hello, Avatar!"); and change it very slightly to say llSay(-47,"Hello, Avatar!");

5.  Click Save.  That will create a script that communcates on channel -47.  Now all you need is a script to hear it. So, ...

6.  Repeat steps 1-3.

7. Find the line after state_entry that says llSay(0,"Hello,Avatar!"); and replace it with llListen(-47, "","","");

8. Find the line that says touch_start (integer total_number) and replace it with listen (integer channel, string name, key id, string message)

9. Find the line after that that says llSay(0,"Hello, Avatar!"); and replace it with llSay(0,message);

That will do it.  You can change the message in the first script so that it doesn't say "Hello, Avatar!", of course, and you can make both scripts more complicated once you learn how to write your own scripts.  Just pay very close atention to spelling, capitalization, and punctuation.  They must be exact or the scripts will fail.  Aslo, keep the two prims within 20m of each other (the normal range for typed chat).

EDITed a couple of times to remove my inevitable typos.  :smileytongue:

Oh the shame of it. A listen request that has no timeout code - giggles. The region will be awash with these requests till he sends the freeing text string - .

[Rolig Loon]

No, there should only be one message sent and received each time someone clicks the first object. The sending script is speaking on channel -47 and the receiving script is speaking on the public chat channel. Its message will not be heard by anyone but avatars within 20m, so thre shouldn;t be any "awash". Now, it IS true that a well-written version of this script would have a way to kill the llListen after a while, but I figured that was more trouble than it was worth -- and more confusing -- for a simple demo.

[KarenMichelle Lane]

I was thinking he'd probably rez a few of the listening prims while he was testing. True, teaching newbies the SL Environmental basics would be a bit daunting at this time.

[Rolig Loon]

Geez, I hope not. Even if he did, though, there'd just be a flock of peeper frogs, each one echoing the basic message one time, and doing it all at once.
