Hi there, i make this code in Rimworld that will multiply item you put to stock pile.
It work, but every 30 minute or so the game just crash.
here's my code:
| Code: | aobscan(INJECT,41 03 C6 41 89 47 58) // should be unique
alloc(newmem,$1000,1C2BA090506)
label(code)
label(return)
newmem:
shl r14d,2
code:
add eax,r14d
mov [r15+58],eax
movsxd rax,dword ptr[rdi+58]
sub eax,r14d
mov [rdi+58],eax
jmp return
//mov rcx,r15
//lea rbp,[rbp+00]
INJECT:
jmp newmem
nop 2
return:
registersymbol(INJECT)
[DISABLE]
INJECT:
db 41 03 C6 41 89 47 58 48 63 47 58 41 2B C6 89 47 58
unregistersymbol(INJECT)
dealloc(newmem)
{
// ORIGINAL CODE - INJECTION POINT: 1C2BA090506
1C2BA0904DC: F2 0F 5A C0 - cvtsd2ss xmm0,xmm0
1C2BA0904E0: 48 8D 64 24 00 - lea rsp,[rsp+00]
1C2BA0904E5: 90 - nop
1C2BA0904E6: 49 BB 80 B6 05 BA C2 01 00 00 - mov r11,000001C2BA05B680
1C2BA0904F0: 41 FF D3 - call r11
1C2BA0904F3: 48 8B D0 - mov rdx,rax
1C2BA0904F6: 49 8B CF - mov rcx,r15
1C2BA0904F9: 49 8B 07 - mov rax,[r15]

1C2BA090502: 49 63 47 58 - movsxd rax,dword ptr [r15+58]
// ---------- INJECTING HERE ----------
1C2BA090506: 41 03 C6 - add eax,r14d
1C2BA090509: 41 89 47 58 - mov [r15+58],eax
// ---------- DONE INJECTING ----------
1C2BA09050D: 48 63 47 58 - movsxd rax,dword ptr [rdi+58]
1C2BA090511: 41 2B C6 - sub eax,r14d
1C2BA090514: 89 47 58 - mov [rdi+58],eax
1C2BA090517: 49 8B CF - mov rcx,r15
1C2BA09051A: 48 8D 6D 00 - lea rbp,[rbp+00]
1C2BA09051E: 49 BB D0 06 09 BA C2 01 00 00 - mov r11,000001C2BA0906D0
1C2BA090528: 41 FF D3 - call r11
1C2BA09052B: 49 8B CF - mov rcx,r15

Replace "alloc(newmem,$1000,1C2BA090506)" w/ "alloc(newmem,$1000,INJECT)".
Get rid of the last 3 original instructions (movsxd/sub/mov) as they shouldn't be overwritten.
I doubt this is the problem, but you should do it anyway: check if "mov [r15+58],eax" accesses any other addresses (right click in disassembler). Leave it running and play the game for a while.
