Hello, I'm new.
Since GTA V has been announced I would like to start learning modding now and I think that GTA IV is the best place until V is released.
The school is now over and this year I studied C++, I know most of the basic stuff like if statements, loops, functions, parameters by value and reference, arrays, bidimensional arrays, structs, input/output with text files and some basic OOP knowledge with pointers, the next year I will study Java and I read that it's similar to C# but I don't know any of them (Java, C#), just some very baisc C# knowledge (let's say the syntax since it's the same C++ uses)
How hard would it be for me to start modding from scratch? Do I need to download something? Thanks for the help!
