I found the address of the blood volume and I tried to change it but it didn't work. And then I click on something and I rewrite it and I find this fstp dword ptr [edi+000000C0] does anybody know how to change this?

This is the address around it
3FE8A2EA - 8B 40 48 - mov eax,[eax+48]
3FE8A2ED - 83 EC 0C - sub esp,0C { 12 }
3FE8A2F0 - 50 - push eax
3FE8A2F1 - 39 00 - cmp [eax],eax
3FE8A2F3 - E8 3027F9FF - call 3FE1CA28
3FE8A2F8 - 83 C4 10 - add esp,10 { 16 }
3FE8A2FB - D9 9F C0000000 - fstp dword ptr [edi+000000C0]
3FE8A301 - 8B 47 10 - mov eax,[edi+10]
3FE8A304 - 8B 40 48 - mov eax,[eax+48]
3FE8A307 - 83 EC 0C - sub esp,0C { 12 }
3FE8A30A - 50 - push eax
3FE8A30B - 39 00 - cmp [eax],eax
3FE8A30D - E8 1627F9FF - call 3FE1CA28
3FE8A312 - 83 C4 10 - add esp,10 { 16 }
3FE8A315 - 8B 87 A8000000 - mov eax,[edi+000000A8]
3FE8A31B - 50 - push eax
