using multiple scripts

I have 2 scripts

one offers a yes/no menu

if yes is selected I want to run the door_open script

currently both scripts run at the same time

here is the code

//DIALOG MENU


integer menu_handler;
integer menu_channel;
menu(key user,string title,list buttons)//make dialog easy, pick a channel by itself and destroy it after 5 seconds
{
menu_channel = (integer)(llFrand(99999.0) * -1);//yup a different channel at each use
menu_handler = llListen(menu_channel,"","","";
llDialog(user,title,buttons,menu_channel);
llSetTimerEvent(5.0);
}

default
{
touch_start(integer t)
{
menu(llDetectedKey(0),"hello world",["yes","no"]);
}
timer() //so the menu timeout and close its listener
{
llSetTimerEvent(0.0);
llListenRemove(menu_handler);
}
listen(integer channel,string name,key id,string message)
{
if (channel == menu_channel) //in case you have others listeners
{
if(message == "yes"
{
//do stuff from the open_door script
}
else if(message == "no"
{
//do other stuffs
}
}
}
}

What was the question?

One is to copy the stuff from the door script into this script.

Another is to use a messaging call to send a message from this script to the door script. (probably best).

Another is to use an llSay(<private channel>...) to send the message.

Another is to have this script write something into object description that the door script detects.

Search for any example of sending messages from one script to another, and use the one that looks easiest to you.

how do I run a single script which then runs the second script ?

so script A is run but within this is an if statement so "if this is true" run script B "else" run script C

Does this make more sense?

You'll likely want to connect the two scripts with link-message operators:

if(x) llMessageLinked(-4,TRUE,"",NULL_KEY);

and..

link_message(integer sender, integer int, string str, key id)
{
if(int != FALSE) //Do stuff
}


That's a VERY basic idea...VERY basic...but it's how you'd work communication between two scripts.

Alternately, you can turn a script on and off with llSetScriptState()...though that does not appear to be what you're looking for in your above example.
