Ferengi (free) trade routes

[Spocks-cuddly-tribble]

The Ferengi (free) trade routes code, by DCER & me


All code locations listed below contain the empire-ID (default 02/ferengi). The feature can be (even partial) disabled via invalid ID (i.e. above 04).

Twice-issued -> need of all locations for a proper functionality!

Code: Select all

4479B9   cmp   cl, 2 // 0x46DBB * trade to minor

459826   cmp   ch, 2 // 0x58C28 *AI to major without treaty & player to minor

40D3C3   cmp   word ptr [esi+8], 2 // 0xC7C7 * AI to minor

43BCAF   cmp   bl, 2 // 0x3B0B1 * player to major without treaty


Trade to majors with non-agression & player after the ending of a treaty:

45EBEF   cmp   word ptr [ecx+34h], 2 // 0x5DFF3
45EBFA   cmp   si, 2                 // 0x5DFFD
45EEDF   cmp   word ptr [ecx+34h], 2 // 0x5E2E3
45EEEA   cmp   si, 2                 // 0x5E2ED
45F151   cmp   word ptr [esi+34h], 2 // 0x5E555
45F18A   cmp   di, 2                 // 0x5E58D

Show systems by non-aggression:

45F17C   mov   edx, 2  // 0x5E57D
45F1B3   mov   edx, 2  // 0x5E5B4


Trade route effect to Minor Attitude:

42A4BF   cmp   dh, 2       // 0x298C1

Trade route effect to AI Empire Attitude:

41F4F2   cmp   ah, 2       // 0x1E8F4

Concerning the value at 0x46DBB note a mod-independent bug allows trading with minor races at war or with invalid treaty for one turn i.e. there is a removal delay of one turn!

In theory the free trading to empires / minors can be divided between different empires. But, as you see, the value at 0x58C28 is here the biggest troublemaker.


Trade GUI warning messages (sub_4D8610)

(no friendship treaty or higher / no race known yet...)

Race-ID to be ignored:

0xD7AFA
0xD7B6E

(during my test either of them sufficed)

0xD7B9C (at WAR with all known races)




Changing this funny value disables ALL AI to major trade. It's a remote possibility AI diplomacy somehow gets stuck....

Code: Select all

40D3A3   mov     ebp,1    // 0xC7A4

Nice work Tribble! Many mods could make use of this.

I hope you're doing good on fixing the ignored message diplomacy bug

Sorry SCT but i want to change the race this applies to from 02 (ferengi) to 00 (cardassians)

I changed to 02 in the above post to 00 to accomplish this. but it hasn't swaped the function. Any idea why?

Just change all empire IDs at the 17 given 0x-addresses and start a new game (otherwise the savegame has to be edited, at least the empsInfo file).

thanks thats got it!

Here's a patch that will totally disable Ferengi free trade. It works by changing the race ID in comparisons from 02 (Ferengi) to FF (invalid).

freetrade0.patch:

Code: Select all

NAME: Disable Ferengi free trade
DESC: This patch requires the Ferengi to establish a friendship treaty to trade with other races.
