项目02《游戏-04-开发》Unity3D

基于项目02《游戏-03-开发》Unity3D ，

因前三集资源以及代码冗余问题，本次项目对前三集进行了重做，资源及代码如下，

首先导入场景及人物资源，

为人物添加动画控制器Animator组件，

创建动画控制器文件夹ACs，并在ACs文件夹下创建Animation Controller命名为PlayerAC角色动画控制器，

0层动画控制器：

1层动画控制器：

2层动画控制器：

创建好角色动画控制器后，将PlayerAC绑定在场景中Player的Animator上，

接下来添加新输入系统，

角色移动（包括跳跃，镜头旋转）

角色攻击（包括连击）

绑定MainGame.cs

双击MainGame.cs修改脚本：

using UnityEngine;
public class MainGame : MonoBehaviour{
public static Player player;
void Awake(){
player = GameObject.Find("Player").GetComponent<Player>();
}
}

绑定摄像机跟随代码：

双击CameraCtrl.cs修改脚本：

using UnityEngine;
public class CameraCtrl : MonoBehaviour{
public float dis;
public float height;
public float speed;
Transform target;
Vector3 targetPos;
void Start(){
target = MainGame.player.transform;
}
void Update(){
transform.LookAt(target.position + Vector3.up * 1.5f);
targetPos = target.forward * (-dis) + target.up * height + target.position;
}
void LateUpdate(){
transform.position = Vector3.Lerp(transform.position, targetPos, speed);
}
}
保存代码后回到unity场景设置数值：

创建角色基类Living.cs：

双击Living.cs脚本，

using UnityEngine;
public class Living : MonoBehaviour{
public Animator Anim { get; set; }
protected virtual void InitValue() {
Anim = GetComponent<Animator>();
}
protected void Start(){
InitValue();
}
}
创建角色类Player.cs：

双击Player.cs修改脚本：

using UnityEngine;
using UnityEngine.InputSystem;
public class Player : Living{
float speed = 3;
float rotate;
bool isHoldRotate;//保持旋转角度
void Start(){
base.Start();
SetInput();
contro = GetComponent<CharacterController>();
}
CharacterController contro;
Controls action;
void SetInput(){
action = new Controls();
action.Enable();
action.PlayerCtrl.Move.started += Move;
action.PlayerCtrl.Move.performed += Move;
action.PlayerCtrl.Move.canceled += StopMove;
action.PlayerCtrl.Jump.started += Jump;
action.PlayerCtrl.Rotate.started += Rotate;
action.PlayerCtrl.Rotate.performed += Rotate;
action.PlayerCtrl.HoldRotate.performed += HoldRotate;
action.PlayerCtrl.HoldRotate.canceled += HoldRotate;
action.PlayerAtt.SwordOut.started += SwordOut;
action.PlayerAtt.Att.started += Attack;
}
void Attack(InputAction.CallbackContext obj){
if (Anim.GetCurrentAnimatorStateInfo(0).IsName("Idle_Fight")){
Anim.SetInteger("AttackID", 1);
Anim.SetTrigger("AttackTrigger");
}
else{
int num = Anim.GetInteger("AttackID");
if (num == 6)
return;
if (Anim.GetCurrentAnimatorStateInfo(0).IsName("Attack_" + num))
Anim.SetInteger("AttackID", num + 1);
}
}
void SwordOut(InputAction.CallbackContext obj){
Anim.SetBool("IsSwordOut", !Anim.GetBool("IsSwordOut"));
}
void HoldRotate(InputAction.CallbackContext obj){
if (obj.phase == InputActionPhase.Canceled)
isHoldRotate = false;
else
isHoldRotate = true;
}
void Rotate(InputAction.CallbackContext obj){
rotate = obj.ReadValue<float>();
}
void Jump(InputAction.CallbackContext obj){
Anim.SetTrigger("JumpTrigger");
}
void StopMove(InputAction.CallbackContext obj){
Anim.SetBool("IsRun", false);
}
void Move(InputAction.CallbackContext obj){
Anim.SetBool("IsRun", true);
}
void Ctrl(){
if (Anim.GetCurrentAnimatorStateInfo(0).IsName("Sprint") ||
Anim.GetCurrentAnimatorStateInfo(0).IsName("Run") ||
Anim.GetCurrentAnimatorStateInfo(0).IsName("Idle_ver_A") ||
Anim.GetCurrentAnimatorStateInfo(0).IsName("Idle_Fight")){
float f = action.PlayerCtrl.Move.ReadValue<float>();
contro.Move(transform.forward * f * Time.deltaTime * speed);
contro.Move(transform.up * -9.8f * Time.deltaTime);
if (isHoldRotate)
transform.Rotate(transform.up * rotate * 0.3f);
}
}
void Update(){
Ctrl();
}
}
