.Map :: MoHAA Mapping

Where is the difference if I do this in a script:

setcvar "mycvar" "value"

or if I do this in my cfg:

Code: Select all

set mycvar "vaule"

also I don't get the difference between these 2 ways to getcvar;
I saw these 2 way and both of them works.

Code: Select all

getcvar"mycvar"

or

Code: Select all

getcvar(mycvar)

Setcvar is a scripting command. Set is a config commands.
Other than that there's no difference, both do exactly the same.

There's no difference. The scripting language just has very elastic rules therefor multiple syntaxes are possible.

I see..ty

Posted: **Wed May 06, 2009 9:03 pm**

and...
can I do that?

Code: Select all

setcvar "nextmap" getcvar(map2)

more exactly, I mean to set a cvar with the value of another cvar

and still talking about cvars..something like that:

Code: Select all

game.map_list = makeArray
(getcvar(map1))
(getcvar(map2))
(getcvar(map3))
(getcvar(map4))
(getcvar(map5))
endArray

will case problems or not works?
I'm asking you becouse the console didn't retourn me errors..but the mod doesnt work!

I've fixed array problem, but still don't get the first to work!!

any advice to do that:

setcvar "nextmap" getcvar(map2)

humm..console didn't display any message, but nextmap cvar is not set as I want!

I mean to set a cvar with the value of another cvar

AFAIK nextmap is not used in MoHAA. The server uses sv_maplist only.

humm..whatta bad news for me!

Posted: **Thu May 07, 2009 4:14 pm**

ok..I've made this little tool to split strings so that I can get maps from sv_maplist cvar:
(I did not tested it, so if you find errors correct me please!)

Code: Select all

string_splitter local.mystring:

local.spitter = " "
local.splitter_conut = 0
local.splitter_count2 = (local.splitter_count + 1)

local.string[] = local.mystring

for(local.i = 0; local.i <= local.string.size; local.i++)
{ //check how many words are composing the string
    if(local.string[local.i] == local.splitter)
        local.splitter_count++
}

game.word_num = 1

for(local.i = 0; local.i <= local.string.size; local.i++)
{
    
    if(local.string[local.i] != local.splitter)
    {   
        game.word[game.word_num][game.char_num] = local.string[local.i]
        game.char_num++
    }
    
    if(local.string[local.i] == local.splitter)
        game.word_num++
    
    if(game.word_num > local.splitter_count2 || game.word_num == local.splitter_count)
    {
        println "Error occurred during string splitting"
        end
    }
    
}
end

ok, now my question is:
HOW CAN I MAKE MY SCR RETURN SOMETHIG??!
i mean something like return for C functions..becouse I would like to use it from separated scripts.
can I use game vars for that?
for exemple:
(remember that I have defined game vars and arrays in the "string splitter" scr)

Code: Select all

main:
    
local.maplist = getcvar(sv_maplist)

local.mystring = local.maplist

waitthread global/string_splitter.scr::string_splitter local.mystring

for(local.i = 1; local.i <= game.word_num; local.i++)
{
    println (game.word[local.i])
}
end

would this print in console maps name of sv_maplist one by one??

also I think this is not the right way:

Code: Select all

local.string[] = local.mystring

but I HAVE to do that..I don't know how in MOH scr leng!
advices?

OK, I don't really have time to check out the logic behind your code, but here's a few comments off the top of my head.

No need to copy local.mystring to local.string. local.mystring is not a reference or a pointer to the original variable, it's a copy and you can safely operate on it without risking corruption of the original data.

I see some typos - splitter_count vs splitter_conut.

Your word counter isn't exactly reliable. In the best case, you will miss the last word, in the worst (e.g. multiple spaces between words) - for example:

Code: Select all

 dm/mohdm1  dm/mohdm2

would be counted by your code as 3 words. It's better to count words as non-interrupted sequences of non-whitespace characters.

Why use the game object? If you want to achieve cross-thread variable visibility, use the level object instead. Game variables are known to be problematic.

Use the "end" keyword and call the thread with "waitthread". For instance:

Code: Select all

local.var = waitthread get_some_value

(...)

get_some_value:
    local.foo = "bar"
end local.foo

As a result of the above, local.var will be assigned the "bar" string. There are no type restrictions - a thread can return anything (even arrays), as long as it fits in 1 variable.

String length:

Code: Select all

local.foo = "bar"
local.strlen = local.foo.size // 3

yeah, I'm use to do useless stuff! lol

OOPS!

I know that but mine is a not a public script, so for now I'll use it with this "functional hole", maybe when I got some more time i'll do it better!

Code:
local.var = waitthread get_some_value

(...)

get_some_value:
local.foo = "bar"

local.foo = "bar"
local.strlen = local.foo.size // 3

oooh that's nice..well you saved me..

this is the way I chose to check my script:

Code: Select all

main: 
    
level.maplist = getcvar(sv_maplist) 

local.mystring = level.maplist

waitthread string_splitter local.mystring

for(local.i = 1; local.i <= level.word_num; local.i++)
{ 
    println (level.word[local.i]) 
} 
end 

string_splitter local.mystring:

local.spitter = " "
local.splitter_count = 0
local.splitter_count2 = (local.splitter_count + 1)

for(local.i = 0; local.i <= ((local.mystring.size) - 1); local.i++)
{ //check how many words are composing the string
    if(local.mystring[local.i] == local.splitter)
        local.splitter_count++
}

level.word_num = 1
level.char_num = 1

for(local.i = 0; local.i <= ((local.mystring.size) - 1); local.i++)
{
    
    if(local.mystring[local.i] != local.splitter)
    {   
        level.word[level.word_num][level.char_num] = local.mystring[local.i]
        level.char_num++
    }
    
    if(local.mystring[local.i] == local.splitter)
        level.word_num++
    
    if(level.word_num > local.splitter_count2 || level.word_num == local.splitter_count)
    {
        println "Error occurred during string splitting"
        end
    }
    
}
end

...everything seems going good, no lenguage error in console, BUT, instead of all my maps, the message in console is this:

Code: Select all

Type 'array'

what's up? why?! lol

Why make one yourself? Elgan has made an excellent set of string-utilities including the splitting of strings. In fact it's the only script I use that's not made by myself. Download his AP menu, the global/strings.scr is in there.

Yes, nextmap is used in MoHAA by the bsptransition and leveltransition commands.

You are printing arrays because for some reason you're using 2 dimensions for simple string spitting and you are only printing the 1st dimension.

well I didn't know of it..I'll try, if you say it's well made and easy to understeand, I'll use it!

Why make one yourself?

I love scripting and programming so I try to learn things doing some stuff I never done(ex. string splitter)!

It's not good to build an dynamic thread on 1 level variable.

Code: Select all

mythread:
local.result = waitthread do_stuff

//....

end


do_stuff:

//...

end local.result
