Protecting games from memory scanners (e.g. Cheat Engine)

I am making a game in C ++ 11 where points are sent to the server. I save the account as a simple float, so people using software like the Cheat Engine can easily change the value of the account before it is sent to the server.

How can I protect my game from such attacks?

There are many options you can make, but it’s best not to accept any important values ​​from the client. Ask the server to do all the calculations and send the values ​​to the client.

In fact, it creates two variables with the same value and moves one of them to different positions in RAM (simply put), which greatly complicates the search. He then compares the values ​​for the differences.

This is simplified code for an idea. I hope this self-description is well commented.

int Value = 0; // variable which we want to protect
int pValue[ 1000 ] = { 0 };
int Pos = 0; // 'pseudo-position' of the element in pValue

while( !GetAsyncKeyState( VK_SPACE ) )
{
    if( pValue[ Pos ] != Value )
        printf( "detected!" );

    ++Value;

    Pos = rand( ) % 1000;
    pValue[ Pos ] = Value;

    Sleep( 10 );
}
