测试场景
https://assetstore.unity.com/packages/3d/environments/landscapes/low-poly-simple-nature-pack-162153
下载好资源包，导入后打开第一个场景
导入后新建一个3D-胶囊体，命名为Player，将相机保留至一个并命名为Main Camera，然后新建空对象命名为GroundCheck
新建CameraController和PlayerController两个脚本，并分别与MainCamera和Player建立关联
CamereController.cs
using System.Collections;using System.Collections.Generic;using UnityEngine;public class CameraController : MonoBehaviour {
public Transform player; private float mouseX, mouseY; //获取鼠标移动的值 public float mouseSensitivity; //鼠标灵敏度 public float xRotation; private void Start () {
Cursor.lockState = CursorLockMode.Locked; } private void Update () {
mouseX = Input.GetAxis ("Mouse X") * mouseSensitivity * Time.deltaTime; mouseY = Input.GetAxis ("Mouse Y") * mouseSensitivity * Time.deltaTime; xRotation -= mouseY; xRotation = Mathf.Clamp (xRotation, -70f, 70f); player.Rotate (Vector3.up * mouseX); transform.localRotation = Quaternion.Euler (xRotation, 0, 0); }}PlayerController
using System.Collections;using System.Collections.Generic;using UnityEngine;public class PlayerController : MonoBehaviour {
private CharacterController cc; public float moveSpeed; public float jumpSpeed; private float horizontalMove, verticalMove; private Vector3 dir; public float gravity; private Vector3 velocity; public Transform groundCheck; public float checkRadius; public LayerMask groundLayer; public bool isGround; private void Start () {
cc = GetComponent (); } private void Update () {
isGround = Physics.CheckSphere (groundCheck.position, checkRadius, groundLayer); if (isGround && velocity.y < 0) {
velocity.y = -2f; } horizontalMove = Input.GetAxis ("Horizontal") * moveSpeed; verticalMove = Input.GetAxis ("Vertical") * moveSpeed; dir = transform.forward * verticalMove + transform.right * horizontalMove; cc.Move (dir * Time.deltaTime); if (Input.GetButtonDown ("Jump") && isGround) {
velocity.y = jumpSpeed; } velocity.y -= gravity * Time.deltaTime; cc.Move (velocity * Time.deltaTime); }} 为场景添加一个Ground图层
将场景改为Ground图层
修改脚本属性值
如果没有碰撞把fbx模型的此项勾选上
效果
装备自旋转与拾取
https://blendswap.com/blend/26019#
使用blender导出fbx，注意坐标系
导入时勾选
导入场景摆好位置
给gun添加Equipment的Tag与Layer
给Player添加Player的Layer
项目设置中Player和Equipment图层取消勾选，忽略碰撞
新建Equipment.cs，与gun绑定
Equipment.cs
using System.Collections;using System.Collections.Generic;using UnityEngine;public class Equipment : MonoBehaviour {
public float speed = 90f; public float moveSpeed = 2f; void Update () {
transform.Rotate (Vector3.forward * Time.deltaTime * speed); }}CameraController.cs
using System.Collections;using System.Collections.Generic;using UnityEngine;public class CameraController : MonoBehaviour {
public float pickDistance; private void Start () {
pickDistance = 2f; } private void Update () {
Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition); RaycastHit hit; if (Physics.Raycast (ray, out hit)) {
if (hit.transform.tag == "Equipment") {
if (hit.distance <= pickDistance) {
if (Input.GetKeyDown (KeyCode.E)) {
DestroyImmediate(hit.transform.gameObject); } } } } }}效果：靠近物品时按E会“收取”物品
人物的行走动画
https://assetstore.unity.com/packages/3d/props/polygon-starter-pack-156819
将前面的主角替换为素材包内人物
找到模型给它添加动画
因为这个素材自带动画，所以稍微剪辑一下，生成一个跑步时的动画和一个静止时的动画
修改Rig属性
给Player添加Animation组件
修改Player.cs
using System.Collections;using System.Collections.Generic;using UnityEngine;public class PlayerController : MonoBehaviour {
private CharacterController cc; private void Start () {
ani=GetComponent(); } private void Update () {
if(Input.GetKey(KeyCode.W)){
ani.Play("Run"); } if(Input.GetKeyUp(KeyCode.W)){
ani.Play("Stay"); } }} 效果
2D按钮的拖动
随便来张卡牌和背景
将卡牌当做按钮
可以方便地添加按下时的效果
编写脚本Card.cs
using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.EventSystems;public class Card : MonoBehaviour {
// Start is called before the first frame update private Vector3 lastMousePosition = Vector3.zero; private Vector3 originPosition; private bool isDrag = false; void Start () {
} // Update is called once per frame void Update () {
} public void MouseEnter () {
if (!isDrag) {
originPosition = transform.position; } } public void MouseExit () {
} public void MouseDrag () {
isDrag=true; if (lastMousePosition != Vector3.zero&&Input.GetMouseButton(0)) {
Vector3 offset = Input.mousePosition - lastMousePosition; transform.position += offset; } lastMousePosition = Input.mousePosition; } public void EndDrag () {
isDrag=false; transform.position = originPosition; lastMousePosition = Vector3.zero; }}添加EventTigger组件，绑定脚本里的函数
效果
技能CD效果
技能图片
新建两个Image，一个Text
将Mask的颜色改为偏灰色
新建一个脚本Skill.cs，用来控制Skill
using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.UI;public class Skill : MonoBehaviour {
public Image mask; public Text cd; public float cdTime = 5f; public bool isCD = false; private bool isClick = false; void Start () {
} void Update () {
if (isClick && !isCD) {
isCD = true; mask.fillAmount = 1; } if (isCD) {
mask.fillAmount -= Time.deltaTime / cdTime; cd.text = "" + Mathf.Ceil (mask.fillAmount * cdTime); cdTime -= Time.deltaTime; if (mask.fillAmount == 0) {
isCD = false; cd.text = ""; cdTime = 5; } } } public void mouseDown () {
if (Input.GetMouseButtonDown (0)) {
isClick = true; } } public void mouseUp () {
if (Input.GetMouseButtonUp (0)) {
isClick = false; } }}为Skill添加Event Trigger组件，并绑定Skill.cs里的函数
Mask和Cd选择对应的对象
Mask和Cd的Raycast Target取消勾选，否则Skill不会响应点击
效果
