Need your help for my script...

Hi all.

After made lovely saunas, i am trying to make showers but i have a problem with scripts that i fixed inside. I am not a specialist of scripts that's why i need your help.
This is what i did :

*In the button of the shower : i fixed 1 script
==========================================================
default
{
touch_start(integer total_number)
{
llMessageLinked(LINK_THIS, 0, "Touched.", NULL_KEY);
}
}
==========================================================





*In showerhead : i fixed 2 scripts

FIRST ONE==================================================

default
{
link_message(integer sender_num, integer num, string str, key id)
{
llSay(0,str);
}
}

SECOND ONE================================================

Fixed like that it doesn't work... Could you explain why and correct my mistake?

You can contact me here or in SL.

Thank you

I can see a couple of potential issues - but I'm not sure what you're trying to do. Can you describe what you want to happen?

The first thing I see is that your touch only results in one of the other scripts saying "touched" - but it doesn't do anything else. Did you want the touch to have some affect on the particles?

Double check your usage of llMessageLinked and link_message. I think in the first script you are telling the script to message itself.

http://wiki.secondlife.com/wiki/Link_message
http://wiki.secondlife.com/wiki/LlMessageLinked

per RaH's comment, change:

llMessageLinked(LINK_THIS, 0, "Touched.", NULL_KEY);

to

llMessageLinked(LINK_SET, 0, "Touched.", NULL_KEY);

To have the showhead hear the shower's message. However, there will still be no affect on the particle system if that is what you're looking for.

In fact, i would like when someone touch the button, the water (particles) runs through the showerhead.

I need for that to "link" the script in the button with the one in the showerhead, isn't it?

Clara,

In the 2nd script you need to run the updateparticles() command not in state_entry() but in link_message(integer sender, integer int, string str, key id).

In addition to the changes to your link-message mentioned before...that should help you get a button-push to start the particles. Problem is, your script doesn't have any ability to turn the particles off.

>>i would like when someone touch the button, the water (particles) runs through the showerhead.>>

And, presumeably, if they touch it again for the particles to stop?

Assuming so, the first thing you need to do is respond to the link message you sent within the script that has the particle system.

So, take this bit from script 1 in the showerhead and move it to script 2 in the showerhead:

link_message(integer sender_num, integer num, string str, key id)
{
llSay(0,str);
}

At that point you can just delete script 1 in the showerhead because it is no longer doing anything.

Then, in script 2 in the showerhead, take your updateParticles() line from the state entry event and put it into the new link message event so that it looks like this:

state_entry()
{
}

link_message(integer sender_num, integer num, string str, key id)
{
updateParticles();
llSay(0,str);
}

That will turn it on. Now, I don't work with particles that much, but I believe to "turn off" a particle system, you have to declare a new one that does nothing to replace the running one. I'm not sure what all parameters would be for llParticleSystem to make a blank system. But once you figure that out, you could do this in script 2 of the showerhead:

integer nShowerOn = 0;

stopParticles()
{
llParticleSystem([a bunch of blank parameters]);
}

default
{

state_entry()
{
stopParticles();
}

link_message(integer sender_num, integer num, string str, key id)
{

if (nShowerOn == 0)
{
nShowerOn = 1;
updateParticles();
}
else
{
stopParticles();
nShowerOn = 0;
}

llSay(0,str);

}

}

For any particle experts out there, if I have this totally wrong, please correct me

The call to stop particles is even simpler, just: llParticleSystem([]); --with a blank rule list.

So in the button i put :

default
{
touch_start(integer total_number)
{
llMessageLinked(LINK_THIS, 0, "Touched.", NULL_KEY);
}
}






And in showerhead, only that :


integer glow = TRUE; // Make the particles glow
integer bounce = FALSE; // Make particles bounce on Z plan of object
integer interpColor = TRUE; // Go from start to end color
integer interpSize = TRUE; // Go from start to end size

If this linkset only has the showerhead that needs to do something scripted then you could actually make your script much easier. You do not need to put a script at all in the shower handle and instead of llMessageLinked in the shower head, you use touch_start. Whenever they touch the shower handle then the touch is passed to the shower head. Then in your particle script you could either change states to switch from the NULL particle script to the regular one or use the touch integer.

I know, I know it sounds complicated, but it is actually pretty easy. I'll get a chance to code it up in a little while.

This works perfectly with no script in the handle. Just right click edit and pick the handle first and then the shower head when you link:

integer shower = 1;
