Hi, new to Unity, new to coding here. I’m sure I will leave out pertinent information.
Problem: I don’t want the player to be able to change x or z velocities while jumping or falling. Rather, I want the player to continue with the last x/z velocity inputs while isGrounded. I am using a Character Controller for movement.
Attempted solution: I thought maybe I could update a new Vector3 fallingMove from Vector3 move while player isGrounded. While player !isGrounded, call controller.Move() using fallingMove as parameter instead of move.
Outcome: x and z velocities are 0 while falling/jumping. In essence, player falls straight down.
Thank you in advance for any help or advice. My movement script is below. My attempted solution is inside PlayerMove().
