①運用axis進行人物移動控制

using UnityEngine;

public class MoveCtr : MonoBehaviour {
    private float _v;
    private float _h;
    private Rigidbody _rig;
    public int moveSpeed = 8;
	void Start () {
        _v = 0;
        _h = 0;
        _rig = GetComponent<Rigidbody>();
        _rig.useGravity =
 
 false;
	}
	
	void Update () {
		
	}
    private void FixedUpdate()
    {
        _v = Input.GetAxis("Vertical");
        _h = Input.GetAxis("Horizontal");
        Vector3 v3 = new Vector3(_h, 0, _v).normalized;
        _rig.velocity = v3 * moveSpeed;
    }
}
