| I have written this in jscript, and everything is working, with the exception of a world.savestate() call. To be a bit more specific, I moved the savestate to it's one function and I have an alias that passes to it, it works fine. I have another 30-40 line alias that handles changing the eq, and it calls the same function - but it doesn't seem to save the state. I have echo's in place just to double check everything - the echo's come out right, but the state is never actually saved for some reason. The code for the function:
function setCurEQ(curSet)
{
test = world.SetVariable("curEqSet", curSet);
world.SaveState();
curEqSet = world.GetVariable("curEqSet");
world.note("Your Current EQ Set is now: " + curEqSet);
}
If you notice, I echo the var from a GetVariable statement, and it does seem to confirm the change. But if I echo the var out after that function is run - the varaible is what it was before the change. This is the last thing I need to get this script functioning and it is driving me nuts!
Thx for any help,

| Ok,
After a bit more testing, SaveState returns 0 in the function above when it works right. In the case where it doesn't work, it is returning a 30035 which is eNotAPlugin?!
Anyone have any idea what I am doing wrong?

| I hope I am not overloading anyone who is reading this, but I am going to attach the alias and the function is calls - this is the function that calls the above function to save the variable. It appears any savestate that is done by this function(changeEQ) or any it calls, it returns error code 30035.
<alias
match="^eq (.*)$"
enabled="y"
regexp="y"
name="eq"
script="changeEQ"
sequence="100"
send_to="12"
>
</alias>
function changeEQ()
{
newEqSet = world.getaliasinfo("eq", 101);
innerRobe = world.GetVariable("innerRobe");
curEqSet = world.GetVariable("curEqSet");
eqArray = readEQ();
curSetNum = findSet(eqArray, curEqSet);
newSetNum = findSet(eqArray, newEqSet);
curContainer = eqArray[curSetNum][19];
newContainer = eqArray[newSetNum][19];
curRobe = eqArray[curSetNum][13];
newRobe = eqArray[newSetNum][13];
newSet = eqArray[newSetNum];
curSet = eqArray[curSetNum];
world.execute("rem all");
world.execute("get " + innerRobe + " " + curRobe);
if (curRobe != newContainer)
{
world.execute("get " + newContainer + " " + innerRobe);
}
if (curRobe != curContainer)
{
world.execute("get " + curContainer + " " + innerRobe);
}
for (i = 1; i < newSet.length; i++)
{
if ((newSet[i] != curSet[i]) & (i != 13) & (i != 19))
{
world.execute("put " + curSet[i] + " " + curContainer);
}
}
world.execute("get all from " + " " + newContainer);
if (newRobe != curContainer)
{
world.execute("put " + curContainer + " " + innerRobe);
}
if ((curRobe != curContainer) & (curRobe != newRobe))
{
world.execute("put " + curRobe + " " + innerRobe);
}
if (newRobe != newContainer)
{
world.execute("put " + newContainer + " " + innerRobe);
}
world.execute("put " + innerRobe + " " + newRobe);
world.execute("wear all");
setCurEQ(newEqSet);
}
Thx for any help :)

| I am not familiar with Jscript, and I don't know what code you have outside of that function, but if it were VBS, I might be asking if you are managing the scope of your variables correctly.
That is, variables declared inside a function or subroutine only exist while that routine is in use. If you want to access the value outside your routine, you need to ensure it is a global variable. (This is pretty standard behavior in most programming languages).
BTW, I have an almost identical plugin, written in VBS. Mine is geared towards a mud called "Ages of Despair", altough it would probably be adaptable to other muds. If you are interested, it's on my webpage, the URL is in my sig. |

| Magnum,
Everything is this script is handled thru local function scoped variables. If something goes between functions, I just set it as a world variable. My understanding is that world.Get and world.Set variables working for any language, and so does world.SaveState().
As you can see, the function in question is only a 4 lines piece of code, but that is the one that isn't working right - when called from the changeEQ function.
As this point, I am not even sure what debugging I should do to try and find this bug. I think this is more of a MushClient bug than bad jscript?
Thx,

| | Can you clarify something? It isn't obvious from your post. Is this script actually in a plugin, or is it running outside a plugin? |

| I notice you are using "world.execute" a fair bit. I suspect the problem is to do with this. Either you are executing something that calls that script, or the way execute works has a bug, but basically when you 'execute' a command you are re-submitting it outside of the context of the current plugin.
For example, if plugin A does "execute X" and X is actually implemented in plugin B, then X will run in the context of plugin B, not plugin A, or no plugin if X is implemented globally.
However what might be happening is that the execute command is discarding the current plugin state, thus leading to the error message you get. One simple approach might be to rearrange the sequence so that your call to the "save state" is done before any execute statements. |

| | Why use world.execute and not world.send? If world.execute has all those problems, and all you're sending is plain text (i.e. no aliases or anything) seems to me that that's a much simpler option. |
