I'm trying to use a global flag on the lines of:

runonce = {}

function teststuff_init(e)
runonce[e] = 0
end

function teststuff_main(e)
if runonce[e] == 0 then
-- do stuff
runonce[e] = 1
end
end

Instead it doesn't seem to work. I don't want to have to save a piece of code for each object.
Anyone have any ideas?
Thanks

If you want a flag use a flag, i.e. g_runonce[e] = true.

Then the code simply becomes if g_runonce[e] then .... g_runonce[e] = false

Be warned though that I find the 'init' function is not guaranteed to be run every time for some reason.

fair enough but it's still not functioning.

It doesn't appear to ever set the value.

Try rebooting GG to see if it works then. It should at least work the first time you test it.

are you trying to have 1 variable toggle between multiple scripts?
you have the array set per entity like that, you want it to just be a normal variable if it will be affected by all of them
i.e.

otherwise they will all get their own version of the variable
like runonce[1] = 0
runonce[2] = 0
runonce[3] = 1
etc

Their own version of the variable is what I want.

Otherwise what happens is one of the items sets runonce to 1 and the rest of them never do their initial run.

Also so what I'm trying to do is have one variable, on one script, used by multiple objects.
So each individual object will all run this same script, but then toggle their own flag.
I don't want to have to make a separate script for each object, which is just asinine.

well then your initial code is correct, most likely you are just making a mistake somewhere - double check all spelling and that you aren't toggling the variable in any wrong places

So I think I got it. I did have to use 0 and 1, btw. Using true/false wouldn't set.
I don't know why?

Final code:
objname={}
g_runonce={}
function teststuff_init(e)
g_runonce[e] = 0
end

function teststuff_init_name(e, name)
objname[e] = name

end

function teststuff_main(e)
if g_runonce[e] == 0 or g_runonce[e] == nil then
customfunction(objname[e])
g_runonce[e] = 1
end
end

Aha, you have two 'init' functions, I don't think that will work only one or the other but not both!

It works now because you added an explicit check for 'nil' which is what it will always give when not initialised!

I thought the init part was only supposed to run once, when the script is first spawned, hence the name init (short for initialize).

It is, sometimes it doesn't or at least it may not get called before the first 'main' call.

ah I see, not noticed that happening yet, but I don't do much in the way of scripting anyway.

I don't think the double init functions matter or it'd affect 90% of the programs made where someone is referencing smallg's code

the nil was actually a holdover from a previous attempt with the false/true settings. I took it out and it functioned just fine without it. For whatever reason, setting a table to have a value of true/false was breaking things.

Pretty sure I have never used a double init, there's no reason to, they both would do the same thing except one can return the name property, I also had no idea multiple would work but I guess it makes sense, they are only functions after all

Could have sworn I got it from your blood code. Maybe not? I'd have to check but whatever. It is what it is. Thanks for the help either way guys.
