menu button toggles between to messages?

Hi,
I'm working with a dialog menu script and I know how to make 2 buttons which do the opposite of each other, but what I'd really like to do is have one button that when clicked in the dialog menu does one thing, then when clicked again does the opposite.

I'm really not sure how to set it up. I've blindly tried a few things, but I know I'm way off.

I'd like it to send this message on the first click:
llMessageLinked(LINK_SET, 0, "up", NULL_KEY);

then this on the second click:
llMessageLinked(LINK_SET, 0, "down", NULL_KEY);

then on the third click it would send the first message again.

Any tips would be greatly appreciated.

Also is it possible to change the text on the doalog button after it is clicked?

could add a simple check and set an integer

integer dialog_state = FALSE; //FALSE = down, TRUE = up

if (dialog_state) {
llMessageLinked(LINK_SET, 0, "up", ""; dialog_state = TRUE;
} else {
llMessageLinked(LINK_SET, 0, "down", ""; dialog_state = FALSE;
}


just an idea to for an approach

Thanks, I'll play with it a bit but,

That works for the "up message, but it doesn't send the down message, just resends the up message.

if ("Open" {
llMessageLinked(LINK_SET, 0, "up", ""; dialog_state = TRUE;
displayDialog(id, "Up", FishTank, 1);
}
else
{
llMessageLinked(LINK_SET, 0, "down", ""; dialog_state = FALSE;
displayDialog(id, "Down", FishTank, 1);
}

That is because the if ("Open" will always return true (because "Open" is going to equal "Open"

As Alicia said, replace if ("Open" with if (dialog_state) and it should work

More specifically, the string "Open" is a non-zero value, hence it evaluates as true. An empty string would evaluate as false.

integer dialog_state = FALSE;
integer CHANNEL = 42;

default
{
state_entry()
{
llListen(CHANNEL, "", "", "";
}

touch_start(integer usr)
{
if (dialog_state) {
llMessageLinked(LINK_SET, 0, "up", ""; dialog_state = FALSE;
llDialog(llDetectedKey(0), "We can only go Up!", ["Up", "exit"], CHANNEL);
} else {
llMessageLinked(LINK_SET, 0, "down", ""; dialog_state = TRUE;
llDialog(llDetectedKey(0), "We can only go Down!", ["Down", "exit"], CHANNEL);
}
}
}

as said abouve, just replace the dialog_state to anything but used

Okay well that works great, but it also works great for all my other buttons in the menu too...

Thanks for your help though, very much appricated

integer gBooSwitch

touch_start( integer vIntTouches ){
if (gBooSwitch){
//-- button code A
}else{
//-- button code b
}
gBooSwitch = !gBooSwitch;
}

and if you can incorporate the boolean into your code to get the action you want it could be even simpler

//-- some code that acts oppositely when fed TRUE(1) vs when fed FALSE(0)
gBooSwitch = !gBooSwitch

Another way you could do this that might allow you to avoid changing state between dialogs is to issue the same dialog on two different channels. If you have listens on both channels, you can test which one a message is issued on.

thank you all. I finally got it working. No idea why exactly it works lol, but it does!

woot!
