TankMovement脚本：重点学习 脚本里面的刚体处理运动和转向，以及音效。
Edit —>project setting —>Input查看默认设置：所以才可以通过 w a s d 控制tank移动和转向。
using UnityEngine; public class TankMovement : MonoBehaviour { public int m_PlayerNumber = 1; public float m_Speed = 12f; public float m_TurnSpeed = 180f; public AudioSource m_MovementAudio; public AudioClip m_EngineIdling; public AudioClip m_EngineDriving; public float m_PitchRange = 0.2f; private string m_MovementAxisName; private string m_TurnAxisName; private Rigidbody m_Rigidbody; private float m_MovementInputValue; private float m_TurnInputValue; private float m_OriginalPitch; private void Awake() { m_Rigidbody = GetComponent<Rigidbody>(); } private void OnEnable () { m_Rigidbody.isKinematic = false; m_MovementInputValue = 0f; m_TurnInputValue = 0f; } private void OnDisable () { m_Rigidbody.isKinematic = true; } private void Start() { m_MovementAxisName = "Vertical" + m_PlayerNumber; m_TurnAxisName = "Horizontal" + m_PlayerNumber; m_OriginalPitch = m_MovementAudio.pitch; } private void Update() { // Store the player's input and make sure the audio for the engine is playing. m_MovementInputValue = Input.GetAxis(m_MovementAxisName); m_TurnInputValue = Input.GetAxis(m_TurnAxisName); EngineAudio(); } private void EngineAudio() { // Play the correct audio clip based on whether or not the tank is moving and what audio is currently playing. if (Mathf.Abs(m_MovementInputValue)<0.1f && Mathf.Abs(m_TurnInputValue) < 0.1f) { if (m_MovementAudio.clip == m_EngineDriving) { m_MovementAudio.clip = m_EngineIdling; m_MovementAudio.pitch = Random.Range(m_OriginalPitch - m_PitchRange, m_OriginalPitch + m_PitchRange); m_MovementAudio.Play(); } } else { if (m_MovementAudio.clip == m_EngineIdling) { m_MovementAudio.clip = m_EngineDriving; m_MovementAudio.pitch = Random.Range(m_OriginalPitch - m_PitchRange, m_OriginalPitch + m_PitchRange); m_MovementAudio.Play(); } } } private void FixedUpdate() { // Move and turn the tank. Move(); Turn(); } private void Move() { // Adjust the position of the tank based on the player's input. Vector3 movement = transform.forward * m_MovementInputValue * m_Speed * Time.deltaTime; m_Rigidbody.MovePosition(m_Rigidbody.position + movement); } private void Turn() { // Adjust the rotation of the tank based on the player's input. float turn = m_TurnInputValue * m_TurnSpeed + Time.deltaTime; Quaternion turnRotation = Quaternion.Euler(0f, turn, 0f); m_Rigidbody.MoveRotation(m_Rigidbody.rotation * turnRotation); } }
