I'm trying to modify the player's position in just cause 2.
I have found the x,y,z position address (floats). Then I found out what writes to this address.
I want to be able to input any arbitrary co-ordinates.
Z Position:
| Code: | | movss [011FA2E8],xmm0 |
| Code: |
00779F1D - xorps xmm3,xmm3
00779F20 - jne 00779F40
00779F22 - or [MD2_Final+5C2F50],ebx
00779F28 - movss [MD2_Final+5C2F44],xmm3 // X
00779F30 - movss [MD2_Final+5C2F48],xmm3 // Z
00779F38 - movss [MD2_Final+5C2F4C],xmm3 // Y
00779F40 - movsd xmm0,[eax+54]
00779F45 - movsd xmm1,[eax+58]
00779F4A - movsd xmm2,[eax+5C]
00779F4F - movsd xmm5,[MD2_Final+1EE5FC] // 0
00779F57 - movss [ebp-0C],xmm0
00779F5C - subss xmm0,[MD2_Final+5C2F44] // X
00779F64 - comiss xmm0,xmm3
00779F67 - movss [ebp-08],xmm1
00779F6C - subss xmm1,[MD2_Final+5C2F48] // Z
00779F74 - movss [ebp-04],xmm2
00779F79 - subss xmm2,[MD2_Final+5C2F4C] // Y
00779F81 - jb 00779F88
00779F83 - movaps xmm4,xmm0
00779F86 - jmp 00779F8F
00779F88 - movaps xmm4,xmm5
00779F8B - subss xmm4,xmm0
00779F8F - movsd xmm6,[MD2_Final+1EC734] // 3.00
00779F97 - comiss xmm4,xmm6
00779F9A - ja 00779FC8
00779F9C - comiss xmm1,xmm3
00779F9F - jb 00779FA6
00779FA1 - movaps xmm0,xmm1
00779FA4 - jmp 00779FAD
00779FA6 - movaps xmm0,xmm5
00779FA9 - subss xmm0,xmm1
00779FAD - comiss xmm0,xmm6
00779FB0 - ja 00779FC8
00779FB2 - comiss xmm2,xmm3
00779FB5 - jb 00779FBC
00779FB7 - movaps xmm0,xmm2
00779FBA - jmp 00779FC3 : [StrStrW+93AC8]
00779FBC - movaps xmm0,xmm5
00779FBF - subss xmm0,xmm2
00779FC3 - comiss xmm0,xmm6
00779FC6 - jna 00779FF6
00779FC8 - mov ecx,esi
00779FCA - call 0069A140
00779FCF - movsd xmm0,[ebp-0C]
00779FD4 - movss [MD2_Final+5C2F44],xmm0 // X
00779FDC - movsd xmm0,[ebp-08]
00779FE1 - movss [MD2_Final+5C2F48],xmm0 // Z
00779FE9 - movsd xmm0,[ebp-04]
00779FEE - movss [MD2_Final+5C2F4C],xmm0 // Y
00779FF6 - mov [esi+000002E8],00000007

I've messed around with code injection and replacing stuff with nop but nothing happens.
Cheat engine does not allow me to replace with
| Code: | | movss [MD2_Final+5C2F48],1000 |
How do I create a single floating point value and move it to that address?
If you're interested it's for this iPhone remote app i'm making:

| Cheers, I just can't find the right part to replace, it's working but it has no effect they all just seem to be references to the position not the actual position variable.

I don't know how is the game working but first you need to make sure that if you freeze the address, you cannot move. If you can, obviously the value is not the co-ordinate (or maybe just a copy). Then you need to find a code where you can inject your script to change the value.
