I am trying to obfuscate my Phaser game code so that it can't be easily manipulated. It was built by extending State and Sprite classes mainly, which means I do rarely use variables, but mostly object properties instead. What I have noticed is that UglifyJS wont obfuscate the code, even if using the mangle option, because object properties are not obfuscated. An alternative to this was to use Closure Compiler with ADVANCED_OPTIMIZATIONS mode. This is supposed to obfuscate object properties too, but after throwing hundreds of warnings, the produced code is totally broken. So I was wondering if any of you have had any success with this? PS: I know obfuscated code can still be de-obfuscated. The thing is right now it just takes some basic JS knowledge and 5 minutes reading the code to break the highscores. I'm pretty sure if I can make it harder, cheaters wont spend their time with that.
