First person Tut - Question

Above is the link to the tutorial. I am on section (2.6 - Adding a Mesh to your Character) and I basically coded in the player in instead of using a blue print. Do I have to use the blue print or can I continue via C++? I know this question might seem silly but I’m just started learning and I’m still don’t know about the API.

I was able to add the mesh but I since I didn’t create the BP is there a way around 1 under “Setting up Third person mesh”?
