| Code: | push eax
mov eax,[game.exe+12345678]
mov eax,[eax+1CC]
mov eax,[eax+B0]
mov [eax+0C],(float)100
pop eax |

Yes.
Also make sure to throw a cmp in between to check for dead-ends or your game will crash trying to access a null or invalid pointer. This is very common in some games where the value of the pointer is not yet loaded until you do something in game or in-between level loads. e.g
mov eax,[game.exe+12345678]
cmp eax, 0
je ohshitbacktogame

it would check for a null, if null found it will jump back to game to avoid crash

NO!?!! its just an example. Sigh...if you had read some code injection tutorials i wouldn't have to explain this.
But backtogame is any label that will skip over your pointer address fetching, if you are using CE's autoassemble template, you will write
je originalcode
provided you write your injection in code or newmem section.
Here is another example
newmem:
push eax
mov eax,[game.exe+12345678]
cmp eax, 0
je originalcode
mov eax,[eax+1CC]
cmp eax, 0
je originalcode
mov eax,[eax+B0]
cmp eax, 0
je originalcode
mov [eax+0C],(float)100
originalcode:
pop eax // Notice i placed this here so it will execute either way, if you don't do this way, your will crash. google stack balancing(push instruction/pop instruction) if you don't understand why
If all of this still doesn't make sense. Start fresh, try the cheat engine tutorial, read rydian's guides or just use pointers in the CE cheat list.
