**Ground target data in eaw.exe (notes by Andy) 21.10.2002**
======================================= ==

(Submitted by RAF_Dumoulin)

The table starts at byte offset:

0012 12CE (eaw.exe V1.2) 0011 D2D6 (eaw.exe V1.1) 0012 9AFE (eaw.exe V1.2a)

with the HEX-values:

0100 6B03 0E03 0000 0102 03FF 2616 ...

for the first target, the oil plant (target 01). byte3/4: 6B03 = 875 dec, byte5: 0E = 14 dec, byte6 = 03 and so on, as can be seen in the table below.


 * 1) define FEET *21L //(multiplied with 21 dec)
 * 2) define MILES *0x20000L //(multiplied with 131072 dec = 00002000H)

TAR-TYPE definitions (by Andy)

there are a lot of different target type definitions and combinations of them, but there is a pattern: The tar types are coded as long, that means they consist of 4 bytes. Since it's difficult to explain I'll simply list all types and combinations that appear in the exe file and you will see how the combinations work. I added some examples that do not appear in the exe for better understanding. In the text above the variables are called TAR_TYPE_XXXX (e.g. TAR_TYPE_NONE). To make things easier to read I'll leave the 'TAR-TYPE' string and write '_NONE' only. OK, let's start:

TAR_TYPE definition note

usual targets

=
_NONE 0000 0000 not targetable _ANY 0100 0000 targetable _BRIDGE 0300 0000 seems not to work as target! _AIRFIELD 0800 0000

combinations:

_AIRFIELD|_BOMBER 0C00 0000 _BOMBER seems to make the target work for bombing misions _ANY|_BOMBER 0500 0000 _BOMBER seems to add 04 to the first byte _ANY_|AIRFIELD|_BOMBER 0D00 0000 01 (any)+08 (airf.)+04 (bomber)=0D _BRIDGE|_LONGBRIDGE 4300 0000 don't ask me for the meaning, not targetable _NONE|_DONTSET 8000 0000 _DONTSET appears for trees and radar towers _ANY|_RADAR 0101 0000 _ANY|_RADAR|_DONTSET 8101 0000 appears for radar towers, maybe _DONTSET means to create a cluster of this target type???

AA targets

=
_AAA|_LIGHT_AAA 2000 0001 byte1 set to 20 means AA, byte4 sets the caliber _AAA|_MED_AAA 2000 0002 not used in game in this combination! only in connection with ships _AAA|_HEAVY_AAA 2000 0004 _AAA|_SMALL_ARM 2000 0008 not used in game in this combination! only in connection with tanks

Moving ground ojects (MGO)

=
=============

_MGO|_SHIP 1000 0100 byte1 set to 10 means MGO, byte3 sets type _MGO|_ARMOR 1000 0200 not used in game in this combination cause tanks always have AA capability _MGO|_TRAIN 1000 0400 _MGO|_TRUCK 1000 0800 _MGO|_TURRET 1000 1000 not used in game in this combination! see below

combinations:

_MGO|_SHIP|_AAA|_MED_AAA 3000 0102 byte1: 20 (AA)+10 (MGO)=30, byte3=01 (ship), byte4=02 caliber of AA (Medium) _MGO|_ARMOR|_AAA|_SMALL_ARM 3000 0208 _MGO|_TRAIN|_AAA|_LIGHT_AAA 3000 0401 _MGO|_TRUCK|_AAA|_SMALL_ARM 3000 0808 _MGO|_TURRET|_AAA|_LIGHT_AAA 3000 1001 Very important! this could be used as 'invisible' Flak, it is only used by the Destroyers, but is a additional target type that is unknown so far.

Some ideas:

=
We can now change all characteristics of all ground targets. :o) But all major changes have to go hand in hand with tardata.dat- (that means EAW-World-) editing. This way we could substitute any target for another, even create completely new ones as moving AA or additional tanks, parked aircraft or anything we want.

Maybe the bridges could be simply made targetable by changing their type to _ANY|_BOMBER.

Maybe any ground target can get AA capability by adding an Turret (target type: 73) to it.

Maybe the _DONTSET Flag can be used to create tank platoons...

So, happy HEX-editing. :o)

Greetings, Andy.
