Change touch_start to owner chat command

[Napili Sands]

I'm trying to change Brilliant Scientist's Linkset Resizer to use a chat command form the owner instead of touch_start

I got the menu to come up using a chat command, but the changes seems to break the resizer function.

Is there a simple way to implement this change? I assume the code goes into state_entry.

TIA

Hi Napili,

The script is already listening for commands from the menu, so you can chat to it. The only problem is that the makeMenu function assigns a random chat channel for the menu handler. If you replace the menuChan assignment with a constant, you can then chat on that channel and give the same commands as the menu.

For example, to send commands on channel seven, you'd change...

menuChan = 50000 + (integer)llFrand(50000.00);

to

menuChan = 7;

Typing /7 MIN SIZE in the chat window would then cause the object to scale itself to minimum size.

Changing the channel to 7 works, but if I remove touch_start, or even just comment out  the one line

if (llDetectedKey(0) == llGetOwner()) makeMenu();

in touch_start,  chat commands no longer work.

I have another script that responds to touch, so I need to remove that from the resizer script.

If you want your object to respond only to chat commands, you can eliminate the makeMenu function, but only after moving the lines that start listening for your chat.

Those two lines are:

menuChan = 7; //(or whatever channel number you choose)
handle = llListen(menuChan,"",llGetOwner(),"");

Move those two lines to inside the if(scanLinkSet) section of state_entry(), right after the //llOwnerSay("resizer script ready"); line, so they will start the script listening right away. Once you've moved those two lines you should be able to remove the makeMenu function and the touch_start event handler.

I've edited the code to set the menu channel number at the script's compile time and I've removed the makeMenu function and touch_start handler. I haven't tested this, so caveat emptor. If it doesn't work for you, I'll pop in-world later and make it right.

Thanks for your help.  I needed the menuMaker subroutine, since I don't want to issue menu commands from chat, I want the menu to pop up with a chat command. I added a conditional to check for the chat command "resize" to invoke menuMaker in the listen subtoutine and an additional menuMaker call at the end of the resizeObject subroutine to keep the menu up until the user is finisher resizing.

I'm glad I was able to help, even though I misinterpreted your question!
