AWACS-like script; response from Dreyou

Hi peeps.

On the website http://lockon.but.ru you can in realtime see all types of informations regarding AWACS-like functionality for lo-mac 1.1. I have had contact with the developer of the scripts. Her is reply to me.

groet,

Michiel

-----------------------

I can give my code to anybody who want to dig into my raw source :-). BUT:

1. Code is not complete and finished at this moment

2. Code witten for my specific environment, i.e. -

this little project divide into 3 part:

a) simple export.lua which only push data to collect server;

b) perl daemon which collect and store raw information from export.lua and mp_log into database

(working on different computer)

c) php web site (php+xml+xsl) which get data from database and calculate/dispalay map and stats.

I can give you any part of my code, but bit later (need some time for polish and testing).

With best regards

Andrey Gordeev aka Dreyou.

Hi peeps.

 

On the website http://lockon.but.ru you can in realtime see all types of informations regarding AWACS-like functionality for lo-mac 1.1. I have had

UPDATE:

I have gladly received the code from dreyou. SPAZIBA!! :)

You can get it from my website at http://pappavis.netwerke.biz/spelen/lomac/download or try http://www.lomacfiles.com/modules.php?name=Downloads&d_op=viewdownloaddetails&cid=138&lid=269&ttitle=lo-mac_export_multiplayer#dldetails.

fantastic work m8 !! CAW willbe using this !

No, it won't. May as well just leave the map with all options enabled

I was so far unable to get this script operational, sohere is more info from dreyou about his code. Included a transcript of e-mails i have sent/received from dreyou.

Hi Michiel!

 

Sry, never runnnig this script under Windows. I used specific environment to make this project, used part of codes from other my projects,and never thought about distribution of this scripts. (I prefer to use free software to make noncommercial projects :-)

About installing additional perl modules in RedHat (i'm using FedoraCore FC3):

 

1. You must have internet connection

2. Login as root and enter command :

 

perl -MCPAN -eshell

 

At first time this CPAN modules installation script whill ask some questions (give default answers)

 

3. Next, you can install any additional modules by command:

 

install MODULE::NAME

 

for example:

 

install forks

 

then, this shell download, compile and install module

 

Here is the complete list of perl modules for l_server.pl:

 

LWP::Simple

Date::Handler

Date::Handler::Delta

Error

forks

Getopt::Simple

IPC::ShareLite

XML::Simple

XML::LibXSLT

XML::LibXML

 

Also, you must use Apache2,php5 to work web part, if you whant to use another versiosn of apache and php you need to rewrite code.

 

If you want I can give you links to linux rpm modules for php5 and so.

In version 1.1 LockOn export objects coordinates as Lat(mean Y) and Long (mean X) (may be it can export this values in another format, but I don't know how) . This values represented in floating point format, for example:

Lat = 44.556688 - where 44 - degrees and 556688 - min(') and sec(") convertend to decimal format. In normal way this coordinate may be shown (not real conversion, just for

exmaple) as 44.34'77". I.e. we have linear map coordinates, and can conver it to picture coordinates. To do this I make the mission with 2 objecst, placed in opposite cornerns of map region(left/top - right/bottom). Then, I started misson, get coordinates of this objects (using export.lua), and make screenshot (where this object shown both).

 

Next, now we have coordinates and map picture. From picture we can get pixel coordinates of objects, and calculate coefficients to convert real coordinates to picture coordinates.

 

P0 - object 0

P1 - object 1

 

Lat,Long - real coord

y,x - pix coord

0 1 2

3 4 5 6 7

So, we have constants - P0Lat, P0y, P0Long, P0x, P1Lat, P1y, P1Long, P1x

 

cfY = (P0y-P1y) / (P0Lat-P1Lat);

cfX = (P0Long- P1x) / (P0Long-P1Long);

 

Next, convert current real coordinates to current map pix coordinates

 

Lat - current Lat

Long - current Long

posy - current posy

posx - current posx

 

posy (((Lat-P0Lat)*cfY)+P0y)

posx (((Long- P0Long)*cfX)+P0x)

No comments :-))), really, have the plans to make smth. Not now, but bit later. About guidelines, not shure, please ask, and I try to answer.

 

 

 

 

Sry for my bad english.
