Touch as a toggle?

I'm using code I've used before on other projects for the positioning and rotation, so I'm fairly sure that it works.

However, this time, I'm trying to use touch as a toggle instead of voice commands, and I am getting some weird behavior, like it running through the entire process 3 times before returning to it's original state.

the controller code:

CODE
string screen = "open";
default
{
    
    touch_end(integer total_count)
    {
        if ( screen == "open")
        {
            llMessageLinked(-2, 0, "close", NULL_KEY);
            screen = "closed";
        }
        
        if ( screen == "closed" )
        {
            llMessageLinked(-2, 0, "open", NULL_KEY);
            screen = "open";
        }
    }
}

try this

CODE
integer toggle;
default
{
    
    touch_end(integer total_count)
    {
        if (toggle)
        {
            llMessageLinked(-2, 0, "close", NULL_KEY);
        }
        
        else
        {
            llMessageLinked(-2, 0, "open", NULL_KEY);
        }
        toggle = !toggle;
    }
}


You will also want to compare llDetectedKey(0) with llGetOwner if you want to filter out all touches except for your own. Hope that helped.

Ah, yes, it does, thank you :D

As for owner only, I haven't decided if I will yet, and that stuff is easier to manage... for me it's just getting things to move around properly, then moving on to the control limits.

Hey, Cid, are your script able to reopen when it is closed?
I think it should be just replace "if ( screen == "closed" )" by "else if ( screen == "closed" )".

Sorry, Cid, I missed your "toggle = !toggle;" were out of if-else conditions. :o

There's another way to do this too, if you are interested. It involves states.

CODE

default
{
     state_entry()
     {
     }

     touch_start(integer numdetected)
     {
          // switch on.
          state on;
     }
}

state on
{
     state_entry()
     {
     }

     touch_start(integer numdetected)
     {
          // switch back to default.
          state default;
     }
}


There are many interesting things you can do with states depending on what you are trying to accomplish. Don't forget them! :D

Well, it's just me closing a laptop cover.

But I'm a newbie scripter so I like any ideas on how to go about doing things.

CODE

integer toggle;
default
{
    touch_end(integer total_count)
    {
        llMessageLinked(LINK_SET, 0, llList2String(["closed","open"], toggle = !toggle), NULL_KEY); 
    }
}

CODE

integer v_state;

default 
{
     touch_start (integer whatever)
     {
       if (v_state == 0) 
         {
           llWhatever(stuff);
           v_state = 1;
         }
      else 
         {
           llWhatever(stuff);
           v_state = 0;
         }
}


yet another way to do it (heh not really)

You're hoping that Mono will let you script in Perl, right? :)

Actually, that looks like something I'd have written ten or twenty years ago, back when I was an IOCCC finalist and seeing how much Postscript I could cram into the 4 lines allowed in a sigfile.

I grew up coding on a calculator that had very limited memory and it would leak memory. I learned how to write ugly tight code. C++ is my language of choice. I could care less about Perl; As long as the floating-point module that LL decides to use is decent i'll be happy.

LSL is an un-optimisized language at present.

Er, yeh, but even a simple code generator would generate pretty much the same code for the straightforward source and the "compressed" source.

Though I'm not much impressed by the LSL compiler technology. It seems to do greedy tokenization of negative numbers, so "i - 1" is legal but "i-1" is a syntax error because it's interpreting it as an identifier followed by a negative number.

If we're judging by compactness of code, yes. If we're judging by readability (and, by extension, maintainability), I think the prize would go to you here. :)

Wow, your response looks a lot like what first came to mind for me:

CODE

list TOGGLE_STATUS = [ 0xdeadbeef, 0xfeedface ];

integer toggle;

default {
    touch_end( integer total_num ) {
        toggle = !toggle;
        
        llMessageLinked( LINK_SET,
                llList2Integer( TOGGLE_STATUS, toggle ),
                "",
                NULL_KEY
            );
    }
}


The biggest difference that i see is that i did integers instead of strings. This is because i've done enough C programming to distrust and stray away from strings wherever humanly possible. However it is that LSL does its message passing, comparison, assignment, etc., a four-byte integer has got to be more efficient than a string of characters.

It would be really nice to be able to write assembly for whatever byte-code LSL scripts translate to. That way if you needed something efficient it wouldn't have to be uber-ugly-tight ... or otherwise weird looking. LSL scripts for self-documenting code, LSL assembly for efficiency.
