I have read that it is very easy to hack and recompile an unity game.
\n Also, I read that they have a function (provided by the engine) to
\n determine that the game has been recompiled.<\/p>\n<\/blockquote>\n

Yes, Unity has a function to determine if your game has been de-compiled<\/strong> and recompiled<\/strong> or modified<\/strong> in any way. But the hacker would be smart<\/strong> enough to modify what that function returns<\/strong>, before re-compiling<\/strong> the game. Any protection code you write can be modified<\/strong> or removed<\/strong> by the hacker<\/strong>.<\/p>\n

\n

I release the game, a bad guy hacks it and publish as his own, but
\n somewhere in the depth of the code still there is a check that the
\n game has been recompiled, so that I can display some note to the user
\n or to make the game unplayable.<\/p>\n<\/blockquote>\n

Some one will always try to hack your game. This will be likely if your game is famous and is played by many. Displaying some note to the user wont stop hackers from hacking your game. Making the game unplayable wont either.<\/p>\n

\n

Is it easy to hack a cocos game? Do I need to worry about it? How to
\n make a small copy protection for my game?<\/p>\n<\/blockquote>\n

Any game can be hacked<\/strong>. Depending on the hacker’s experience<\/strong>, the hack could be hard<\/strong> or easy<\/strong> for them. You don’t<\/strong> need to worry<\/strong> about this. Large<\/strong> game companies have dedicated<\/strong> team of programmers<\/strong> that protects<\/strong> their games<\/strong> but it only takes hackers weeks<\/strong> or months<\/strong> to remove every protection<\/strong> from the game<\/strong> and make the game playable<\/strong> once again.<\/p>\n

Spend most of your time making great<\/strong> games and make the game cost to be affordable<\/strong>, then less<\/strong> people will pirate<\/strong> your game. There is no way<\/strong> you can fully<\/strong> stop people from hacking<\/strong> your game no matter<\/strong> the programming language<\/strong> or operating system<\/strong> the game was designed for.<\/p>\n

EDIT<\/strong>:<\/p>\n

    \n
  1. \n

    To add a simple protection you, should obfuscate<\/strong> your C++ code.Obfuscation<\/strong> will make your code more un-readable<\/strong>. For example, if you have a class called PlayerInfo<\/code> that contains the score, Obfuscation will rename the class name to Esfjhsakm4<\/code>. The hacker would have to go through everything one by one to realize what’s going on in your app. You can google C\/C++ Obfuscator<\/strong> for more information.<\/p>\n<\/li>\n

  2. \n

    Another way to protect your code is to give your game a limit of player score over time. Maybe if a player points goes from 0 to 100<\/strong> within a second and you know that is not possible<\/strong> with your game mechanics, you can detect<\/strong> this as a hack and then take action.<\/p>\n<\/li>\n

  3. \n

    If this is a network game, make the game so that players would have to register<\/strong> and sign in<\/strong> to play. Then you can ban the player’s account if you catch them cheating. Also ban their IP Address<\/strong> for 3 days<\/strong> then lift the ban after 3 days<\/strong> but don’t lift the ban on the player’s account<\/strong>. <\/p>\n<\/li>\n

  4. \n

    Detect if an item has been unlocked while the user has not played the level that is required to unlock that item.<\/p>\n<\/li>\n<\/ol>\n

    The big advice is that you don’t let user know that you detected hack in their game. Just take a background action such as changing the games mode from easy<\/strong> to hard<\/strong>, banning the player<\/strong> and make the game annoying. If you close<\/strong> the game when hack is detected, they will remove the code<\/strong> that closes the game.<\/p>\n<\/p><\/div>\n
