Installation guide

This guide is the installation guide from scratch to the latest version of EECH. I will try to keep it "lean and mean". So here it goes:

Basic Install

====> Start here if you own EEAH

1. Install EE - Apache Havoc from CD and run once to unpack the graphics files.
   
   
2. Patch EEAH up to patch 1.1E, run once.

====> Start here if you only have EECH, one click install method

1. Install EE - Comanche Hokum from the CD.
   
   
2. All mods as one mega download! This is a snapshot until 20 June 2007 including version 1.8.6. Get it at EechCentral: EECHAllMods.exe (file is 547 Mbyte and unpacks to 1.5 Gbyte)

That's it, now go and read this!

====> Alternative method if you want to control each mod that you download

1. Download and install patch 141C from the Razorworks site: documentation is here (if you have the US version you must install this even if you run the latest modded versions, this is a classic mess-up). Note that the last official version released by Razowworks is 147x. You don't need this one, it is replaced by the modded versions.
   
   
2. Ddownload and install the the updater tool eechupdater1.3.exe. It is pretty much self exlanatory. It maintains an up to date list that is checked against a server list. There are about 25 downloads (including the lastest exe, sounds, addons (see below)).
   
   A keychart which includes the latest mod changes is here
   
   
3. Or the DIY method: you can download all files manually at eechcentral

====> READ THIS!

Important: the files eech.ini and game.cfg determine game options and are automatically created when you run the game the first time. In case of trouble please read this. If there are new options the old eech.ini will still be read and the new options added when you leave the game. Start the game once and leave it to see which options are added. In principle all options are set to defaults which means that most mods are not active. (Note that eech.ini is a product of the modded exe. The official Razorworks exe doesn't create or use it)

Important: in cohokum, the default "avionics" setting in the options menu is set at "novice". This means that you cannot operate the targeting systems, it is done for you in the game by the "copilot". Set this option to advaced when in the game for full manual control of the targeting systems. When you delete the game.cfg and it is recreated by the game, the option is reset at novice!

Important: Information on eech.ini, mods, features etc. etc. are described in the readme.

 

Addons

All addons are exe's created with the NSIS install system. The addons will be installed directly in your Razorworks directory, using the correct path names etc. The best thing is to use the updater tool to download these addons.

NOTE: to use modded textures you have to set the following options in eech.in:

texture_colour=1
mipmapping=1
texture_filtering=1
dynamic_water=1

Go here for more some information on the textures, the directories that are created and what they do.

These addons are directly available from www.eechcentral.com or with the updater tool (see above).

Trouble shooting

If your game doesn't run properly, there is not so much that can be done!

• If you have some weird behaviour, go to the directory razorworks\cohokum and delete the files game.cfg which contains all the settings of the in-game user interface, and eech.ini which contains additional and settings for mods, in the cohokum directory. These files are regenerated automatically. NOTE: when you delete game.cfg the avionics in the options screen is reset to "novice" and the targeting systems do not work, you have to set it to "advanced" to make it work again.
  
• A fresh install has been known to help in many cases (but its a pain).
  
• Set the screen refresh to "always on" for Radeon cards
  
• Some people reported display problems with NVIDIA drivers 71.xx, use drivers from the 81.xx series, that seems to solve the problems
  
• Please try to repeat the error and report about it on the SimHQ - EECH forum. There is a file error.log in your cohokum directory when the game crashes but it is a memory stack dump and pretty useless, no need to report that.
  
• You can ask for a debug version at the SimHQ forum that may help tou understand what is going on because it gives much more output.

Multiplayer guide (not complete)

*** Thanks to Moje ***

Programmers in the DevGroup (mostly Jabberwock, Moje, Schorpp and Jens Wegener, x-cuse me if I forgot some of you) has struggled with the MP-code. Kimchock has helped a great deal. EECH has always been good in LAN but couldn't cope with the Internet lag. This has lead to many changes which means that the description given below is only valid for the latest version 162W1 and later. This version will *not* connect to older versions!

I will assume that you have installed the game as described above, so you have the various add-ons and custom maps!

Setting up the hardware

Getting a MP-game going isn't that hard. First there are a few things you should realize:

• A Firewall of any kind (software or hardware) is crucuial to survive on todays internet but it is bad for MP.
• EECH is a peer-to-peer Multiplayer application.
• EECH is supported by DirectX7 and it's Directplay4 code. This means the game uses TCP and UDP ports 47624 to initialize a connection: the host is activly listening for incoming calls on port 47624. In other words, this port has to be open on both client and host.
• When an incoming call is received the game starts to negotiate which ports to use for subsequent communications. Directplay 4 chooses a port randomly in the range 2300 - 2400 TCP/UDP. Therefore all these ports have to be open!

So in order to get this to work you have to make sure that any hardware firewall in your broadband modem is off. Many modems have that as a menu option in a configuration program. I have to connect to my modem using telnet: see here.

You have to make sure that the the following TCP and UDP ports are open:
TCP/UDP 47624 and TCP/UDP 2300 - 2400 (the whole range). Some modems have the software for that, others don't. This may be a helpfull tool: DXport.

While the hardware firewall is off are vulnerable so make sure you have a software firewall runnning, e.g. Zonealarm which has a free version. If you do that however, you have to give the program cohokum.exe permission to use ports 2300 to 2400 and port 47624.

 

Setting up the game

You can see what games are running here

First of all you cannot connect a game that has a different version number than the host, so 161 connects to 161, 162 to 162 etc. You may crash the host if you try that anyway, so be careful please!

A number of settings in the eech.ini file are default in the correct setting. In case of trouble check if they are:

ipa=                      <= leave empty
session filter=1
usemaster=1
pss=hoxdna.org
sss=eech.dhs.org
cvc=1

The rest is easy:

1. Start the game and choose options, select multiplayer. Select TCP/IP as a connection but do not type in an IP number:
   
2. Go back to the main screen, click on combat and click on the top of the campaign list that says multiplayer (note: if the option "filter" in eech.ini is set to 0 you see a long list of campaigns and skirmishes here):
   
3. You should get a running host in red, click on it and after a short pause a green text should appear telling you wich campaign is on:
   [image here]
4. Click on the green MP game and follow the joining procedure, clicking
   your way into the game:
   [image here]
5. If you don't see the green line appearing your firewall may still be on. Or else quit the game and try again. Sometimes a few tries are needed.
6. Fly low and slow when expecting enemies nearby!

 

Firewall

In my modem, an Alcatel Speedtouch home, I have to do everything by hand. So I set the hardware firewall off using telnet. The modem's address is 10.0.0.138. In my case the username is expert, but it may be something else. The telnet program is part of windows, it runs in a DOS command window.

telnet 10.0.0.138
username: xxxxxx

The command to set the firewall off is:

ip config firewalling=off

to set it back on it is:

ip config firewalling=on

to check it:

ip config

While it is off you are vulnerable. make sure you have a software firewall running.

Changes to the texture setup, nov 2005

New warzones and new textures are made for this game all the time which is great. The game was not set up to handle that properly. I therefore made a couple of changes that makes the game recognize new warzones automatically, and treat them as the 6 regular warzones. This calls for some changes in the texture directories.

The old setup did not distinguish between desert and normal campaigns, so the textures for Kuwait and Lybia were in fact default textures changed to a desert look. The new setup recognizes 3 different textures: default, desert and winter textures. A winter texture ends with "-W" and a desert texture ends with "-D". The code will check if the campaign is a desert or winter campaign and will use the "-D" or "-W" textures if it finds them. If not the defaults are used. Examples:
  

• 66_ANTI_RADAR_PAINT.bmp (default)
• 66_ANTI_RADAR_PAINT-W.bmp (winter)
• 66_ANTI_RADAR_PAINT-D.bmp (desert)

This indication can be added to all textures (trees, cockpit etc.). The "season" button was added to the session screen in the game where you can choose summer, winter or desert, but not all campaigns will have those options (desert and winter are exclusive).

This has the following consequences:

1. The old texture directories for the custom campaigns are no longer needed: \razorworks\cohokum\graphics\textures\alaska,
   \razorworks\cohokum\graphics\textures\aleut,
   \razorworks\cohokum\graphics\textures\kuwait,
   \razorworks\cohokum\graphics\textures\lybia,
   these can be deleted! In any case they are ignored.
   
   
2. The directories:
   camoflage \razorworks\cohokum\graphics\textures\camo
   cockpit \razorworks\cohokum\graphics\textures\cockpit
   general \razorworks\cohokum\graphics\textures\general
   are still there but now contain more textures with "-D" and "-W" indications.
   
   
3. The terrain texture dirs now also have the custom warzones and dynamic water:
   \razorworks\cohokum\graphics\textures\terrain\alaska
   \razorworks\cohokum\graphics\textures\terrain\aleut
   \razorworks\cohokum\graphics\textures\terrain\kuwait
   \razorworks\cohokum\graphics\textures\terrain\lybia
   \razorworks\cohokum\graphics\textures\terrain\grand
   \razorworks\cohokum\graphics\textures\terrain\cuba
   \razorworks\cohokum\graphics\textures\terrain\georgia
   \razorworks\cohokum\graphics\textures\terrain\lebanon
   \razorworks\cohokum\graphics\textures\terrain\taiwan
   \razorworks\cohokum\graphics\textures\terrain\thailand
   \razorworks\cohokum\graphics\textures\terrain\yemen
   \razorworks\cohokum\graphics\textures\terrain\water
   
   
4. You DON'T have to copy these yourself, there are new texture packs that put the correct textures at the correct place. These new texture packs will NOT delete anything because that would mean destroyning peoples work. You have to do that yourself.
   
   
5. The following packs are obsolete and replaced by others:

• superpatch2
• texture_packgcc
• texturepack_addonmaps
• alaskatreespack

AND FINALLY TWO REMARKS:

• The system with the texture_dirs.txt file in the map directories that lets you include your own dir is still working (if you don't know what I am talking about then forget I said this).
• You can put a texture with the same name in more than one directory. The last one is used in the game and a "dds" file takes precedence over a "bmp" file. The directories are searched in this order:
