	f = new NativeFunction(symbol.address, 'pointer', ['pointer', 'int'])
	f(ptr(moneyObject), amount)
	
}


//Gold hack

//Car hack

});

ProgressHack()
MoneyHack(10000)
GoldHack(1000)

How do I run this or where do I store this script for it to run on my Android device?

Where is the money and gold definition in real racing's source code?
I unpack the apk and decompile the "classes.dex" and "classes2.dex" but can't find relative code.
