Initial Number of Orbitals for Minor Races

Posted: Sat Jul 31, 2010 11:37 am

By default, minor races start off with one orbital battery per 50 population (rounded down). The divisor (i.e. the "50") is stored in trek.exe at position 0x50AE6 and can be modified to make minors start with more (or less) orbitals Smile

Assembler Code:

Code:

:004516CD 8B842462010000 mov eax, dword[esp+00000162] // get star...
:004516D4 C1F810 sar eax, 10 // ... system ID
:004516D7 69C028030000 imul eax, 00000328 // multiply by size of a star system entry
:004516DD 8B15C8365A00 mov edx, dword[005A36C8] // systInfo offset
:004516E3 01D0 add eax, edx // data offset for current star system
:004516E5 B932000000 mov ecx, 00000032 // divisor
:004516EA 8B4040 mov eax, dword[eax+40] // (starting) population number
:004516ED 31D2 xor edx, edx
:004516EF F7F1 div ecx // division
:004516F1 8BB42464010000 mov esi, dword[esp+00000164]
:004516F8 89C3 mov ebx, eax // number of orbitals = result of division
:004516FA 31C9 xor ecx, ecx
:004516FC 85C0 test eax, eax
:004516FE 7E14 jle 00451714 // skip loop if number is zero
:00451700 BF05000000 mov edi, 00000005 // orbital battery ID
---------
:00451705 0FBFC6 movsx eax, si
:00451708 89FA mov edx, edi
:0045170A 41 inc ecx // increase loop counter
:0045170B E8E046FFFF call 00445DF0 // create building specified by ID
:00451710 39D9 cmp ecx, ebx
:00451712 7CF1 jl 00451705 // loop

Note that minors will be very hard to conquer if they start with lots of orbitals, even if their tech levels are low, because there's a feature that makes their orbitals do as much damage as level 8 OBs even at the lowest tech levels.
