Hi Phoenix!
I’m glad you have decided to start creating your first game!
As an experienced game developer I would like to suggest not using ChatGPT to write the code for you entirely. If you have some knowledge of how to program in C# and have already programmed a script (platforming controls in your case maybe) to speed things up it’s okay to use these types of tools, but don’t use it if you have never typed it out yourself! Understanding the code is not enough, you should type that yourself piece by piece!
ChatGPT is good for dealing with errors or complicated problems you’re having but never make him do any work or coding. Trust me, he will only slow you down in this learning curve.
