I want to simulate arma 3 like bullet trajectory but I have no idea about how to do it. What should I do? raycast, rigidbody or both? or totally somthing else? I just want to learn about foundations of it. I have a idea but it sounds like it will destroy performance. Creating and destroying rays constantly to curve it or disabling an objects collider and mesh and adding a raycast to it to detect collision. What should I do.
