How do I get my forward movement to match with the direction of my camera?
I'm trying to make my forward movement/W movement match with the forward direction of my camera. using System.Collections; using System.Collections.Generic; using UnityEngine;

}
void Update()
{
// player movement - forward, backward, left, right
float horizontal = Input.GetAxis("Horizontal") * MovementSpeed;
float vertical = Input.GetAxis("Vertical") * MovementSpeed;
characterController.Move((Vector3.right * horizontal + Vector3.forward * vertical) * Time.deltaTime);
// Gravity
if(characterController.isGrounded)
{
velocity = 0;
}
else
{
velocity -= Gravity * Time.deltaTime;
characterController.Move(new Vector3(0, velocity, 0));
}
}
}

You must get a reference to the cameras transform. The transform has a Vector3 "forward", which is the forward direction from the camera. This is what you need to use.
