制作RPG游戏的部分核心代码分析

PlayerMove脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public enum State
{Idle,Walk
}public class PlayerMove : MonoBehaviour
{public float speed = 1;private PlayerDir dir;private CharacterController controller;public State playerState;public bool isMoving = false;// Start is called before the first frame updatevoid Start(){dir = this.transform.GetComponent<PlayerDir>();controller = this.GetComponent<CharacterController>();playerState = State.Idle;}// Update is called once per framevoid Update(){float distance = Vector3.Distance(dir.TargetPosition, transform.position);if (distance > 0.3f){isMoving = true;controller.SimpleMove(transform.forward * speed);playerState = State.Walk;}else{isMoving = false;playerState = State.Idle;}}
}

PlayerDir玩家朝向问题

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerDir : MonoBehaviour
{public GameObject effect_Click;// Start is called before the first frame updateprivate bool isMoving = false;//表示鼠标是否按下private Vector3 targetPosition = Vector3.zero;private PlayerMove playerMove;public Vector3 TargetPosition{get{return targetPosition;}}private Vector3 targetMousePositon;void Start(){targetPosition = transform.position;playerMove = this.GetComponent<PlayerMove>();Debug.Log(UICamera.mainCamera.name);}// Update is called once per framevoid Update(){if(Input.GetMouseButtonDown(0)&&!UICamera.isOverUI){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hitInfo;bool isCollider = Physics.Raycast(ray, out hitInfo);if(isCollider&&hitInfo.collider.tag==Tags.Ground){isMoving = true;LookAtTarget(hitInfo.point);ShowClickEffect(hitInfo.point);}}if(Input.GetMouseButtonUp(0)){isMoving = false;}if(isMoving){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hitInfo;bool isCollider = Physics.Raycast(ray, out hitInfo);if (isCollider && hitInfo.collider.tag == Tags.Ground){LookAtTarget(hitInfo.point);}}else{if(playerMove.isMoving){LookAtTarget(targetPosition);}}}void ShowClickEffect(Vector3 hitPoint){hitPoint = new Vector3(hitPoint.x, hitPoint.y + 0.1f, hitPoint.z);GameObject.Instantiate(effect_Click, hitPoint, Quaternion.identity);}void LookAtTarget(Vector3 hitPoint){targetPosition = hitPoint;targetPosition.y = this.transform.position.y;targetPosition = new Vector3(TargetPosition.x, TargetPosition.y, TargetPosition.z);this.transform.LookAt(targetPosition);}
}

PlayerAnimation脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerAnimation : MonoBehaviour
{private PlayerMove move;private Animation animations;// Start is called before the first frame updatevoid Start(){move = this.GetComponent<PlayerMove>();animations = GetComponent<Animation>();}// Update is called once per framevoid LateUpdate(){if(move.playerState==State.Idle){PlayAnim("Sword-Idle");}else if(move.playerState==State.Walk){PlayAnim("Sword-Walk");}}void PlayAnim(string animName){animations.CrossFade(animName);}
}

相机跟随的脚本

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class FollowPlayer : MonoBehaviour
{private Transform player;// Start is called before the first frame updateprivate Vector3 offsetPosition;public float distance = 0;public float scrollSpeed = 10;private bool isRotating;public float rotateSpeed = 2;void Start(){player = GameObject.FindGameObjectWithTag(Tags.player).transform;transform.LookAt(player);offsetPosition = transform.position - player.position;}// Update is called once per framevoid Update(){transform.position = player.position + offsetPosition;RotateView();ScrollView();}private void RotateView(){Input.GetAxis("Mouse X");Input.GetAxis("Mouse Y");if(Input.GetMouseButtonDown(1)){isRotating = true;}if(Input.GetMouseButtonUp(1)){isRotating = false;}if(isRotating){transform.RotateAround(player.position, Vector3.up, rotateSpeed * Input.GetAxis("Mouse X"));Vector3 originalPos = transform.position;Quaternion originalRotation = transform.rotation;transform.RotateAround(player.position, transform.right, -rotateSpeed * Input.GetAxis("Mouse Y"));float x = transform.eulerAngles.x;// x = Mathf.Clamp(x, 10, 80);// transform.eulerAngles = new Vector3(x, transform.eulerAngles.y, transform.eulerAngles.z);if(x<10||x>80){transform.position = originalPos;transform.rotation = originalRotation;}}offsetPosition = transform.position - player.position;}void ScrollView(){print(Input.GetAxis("Mouse ScrollWheel"));distance = offsetPosition.magnitude;distance += Input.GetAxis("Mouse ScrollWheel")*scrollSpeed;distance = Mathf.Clamp(distance, 2, 18);offsetPosition = offsetPosition.normalized * distance;}
}
