I have owned Playmaker for over a year now but never used it, I instead brought in a friend that was a programmer to help with my game, I dont know anything really about coding. The game is already on Early Access and my friend decided to quit. So now I was looking at using Playmaker so I can finish the game. So I wanted to know how hard it would be to start using Playmaker this far into developing my game, and can I use playmaker to add to his code and adjust it, or do I need to just remove all his code and start from there. His code did not run the entire game, I have other assets working together as well. like Inventory Pro, Opsive third person, Quest System Pro, Enviro, CTS, Easy build and Emerald AI.
The code he wrote ties all these together and includes the save system along with the start screen, Vitals, and main menu, but I have so much more to add to the game so I was thinking playmaker would be a great way for me to do that.
