I came across certain game.it used fld dword ptr [eax+000000C4]//edi esi
how to manually change value in script?

{
// ORIGINAL CODE - INJECTION POINT: GameController:Update+22ca

0629E38D: 8B 45 08 - mov eax,[ebp+08]
0629E390: D9 80 9C 02 00 00 - fld dword ptr [eax+0000029C]
0629E396: DD 9D 38 F2 FF FF - fstp qword ptr [ebp-00000DC8]
0629E39C: 8B 40 48 - mov eax,[eax+48]
0629E39F: 39 00 - cmp [eax],eax
0629E3A1: BA 88 70 D9 1A - mov edx,1AD97088
0629E3A6: 83 EC 0C - sub esp,0C
0629E3A9: 50 - push eax
0629E3AA: E8 B9 A1 F8 FF - call 06228568
0629E3AF: 83 C4 10 - add esp,10
// ---------- INJECTING HERE ----------
0629E3B2: D9 80 C4 00 00 00 - fld dword ptr [eax+000000C4]
// ---------- DONE INJECTING ----------
0629E3B8: D9 05 D0 85 D9 1A - fld dword ptr [1AD985D0]
0629E3BE: 83 EC 08 - sub esp,08
0629E3C1: 83 EC 04 - sub esp,04
0629E3C4: D9 1C 24 - fstp dword ptr [esp]
0629E3C7: 83 EC 04 - sub esp,04
0629E3CA: D9 1C 24 - fstp dword ptr [esp]
0629E3CD: E8 FE AF 00 00 - call 062A93D0
0629E3D2: 83 C4 10 - add esp,10
0629E3D5: DD 85 38 F2 FF FF - fld qword ptr [ebp-00000DC8]
0629E3DB: D9 C9 - fxch st(1)
}

You either change the value at the memory location before that read, or change it in the FPU after it was read.
