Description

« Hide

The ~menu script that is very common in MLP furniture throughout the grid compiles ok on the main grid, but not on the Beta grid. I've tried it in mono sims and in ordinary sims on the Beta grid, but it won't compile in either type of sim. It gives a normal type of script error when compiling ("... not in scope") in both types is sim on the Beta grid, but compiling gives no error on the main grid.

Could you post the script here?

It's a big script. I can let you have it in SL though.

Sounds like one of the cases of undefined behaviour in LSL that we had to fix.
Please paste the smallest part of the script which can demonstrate your problem.

Here is the script I was sent, I am confident this is just another example of ~~VWR-811~~.

It isn't that, Strife.

integer chat = 1;

default {
link_message(integer from, integer num, string str, key id) {
}
}

state on
{
listen(integer channel, string name, key user0, string button)

{ if (chat) llSay(0,"hello world"); }

}

I have a test object in a non-mono sim in the beta grid, with that code in it. It produces the error, saying about the variable 'chat' (line 11), "Name not defined within scope".

As far as I know, when a variable is declared as global, as 'chat' is, it is available everywhere - in all states. If I'm mistaken about that, then it's the main grid that's wrong, because the whole script compiles ok there.

Ah excellent - thats just what I need to fix this problem.

It's probably caused by the fix to http://jira.secondlife.com/browse/SVC-1372

For some unknown legacy reasons 'listen' is actually compiled to 'chat'

That's looks like the answer, Scouse. I tried it with the varbiable's name changed, and it compiled ok. I've no doubt that it will be the same for the whole script, but I have to get back to the Wimbledon final, so I'll check that shortly

The whole script now compiles fine in LSL on the beta grid. I haven't been able to check it in mono yet because there haven't been any mono sims running since I wanted to test it - sometime yesterday (Sunday).

The Mono sims are back up, and I've tested the whole script. With that variable name changed, it compiles ok in both LSL and Mono.

Thank you for the help, Scouse and Strife.
