unity2D横板开发Day2

一，动画：Animator和Animation

给游戏物体绑定Animator

给Animator绑定Controller并添加Animation

 

 动画转变->右击->Make Transition,设置切换条件

 

 

 通过调节Samples控制动画速率

 

 

二，镜头跟随

1，代码实现：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraControl : MonoBehaviour
{
    public Transform player;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        this.transform.position = new Vector3(player.position.x, player.position.y, this.transform.position.z);
    }
}

2，Cinemachine插件

下载：Window->PackageManager->Cinemachine 成功会出现下图所示

 点击创建2D相机，会自动覆盖原相机

 

 基础设置

 Follow  选择跟随物体

Orthographic Size  调节相机大小

Screen X，Screen Y 分别调节相机x，y轴位置

Dead Zone Width  设置空白区域宽度，未超过该区域镜头不跟随

Dead Zone Height  设置空白区域高度，未超过该区域镜头不跟随

 

 Extensions拓展插件

Confiner插件，给该插件绑定一个Polygon Collider 2D 则相机镜头不会超出该部分

如给背景设置一个Polygon Collider 2D（多边形碰撞体）并赋给Confiner插件，则游戏过程中镜头不会超过边界

 

三，今日代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{

    private Rigidbody2D rb;
    public float speed;
    public float jumpforce;
    public LayerMask ground;
    public Animator animator;
    public int cherryNum=0;


    // Start is called before the first frame update
    void Start()
    {
        rb = this.GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        Movement();
        changeAnimation();
    }


    //移动
    void Movement()
    {
        float horizontalmove = Input.GetAxis("Horizontal");
        float facedirection = Input.GetAxisRaw("Horizontal");

        //角色移动
        if (horizontalmove != 0)
        {
            rb.velocity = new Vector2(horizontalmove * speed, rb.velocity.y);
            animator.SetBool("isRun",true);
        }
        else
        {
            animator.SetBool("isRun", false);
        }

        if (facedirection != 0)
        {
            this.transform.localScale = new Vector3(facedirection, this.transform.localScale.y, this.transform.localScale.z);
        }

        //角色跳跃
        if (Input.GetButtonDown("Jump"))
        {
            rb.velocity = new Vector2(rb.velocity.x, jumpforce);
            animator.SetBool("jumping", true);
        }
    }

    //动画切换
    void changeAnimation()
    {
        if (rb.velocity.y < 0)
        {
            animator.SetBool("idle", false);
            animator.SetBool("jumping", false);
            animator.SetBool("falling", true);
        }
        else
        {
            animator.SetBool("idle", true);
            animator.SetBool("falling", false);
        }
    }

    //碰撞检测
    private void OnTriggerEnter2D(Collider2D collision)
    {
        //收藏品销毁与数量计算
        if(collision.tag == "Collection")
        {
            Destroy(collision.gameObject);
            cherryNum += 1;
        }
    }

}

 

四，OnTriggerEnter2D

碰撞检测，该碰撞体需要勾选isTrigger

本Demo中需要检测是否碰撞到收藏品来进行销毁和加分操作

则通过添加修改游戏中收藏品Tag为“Collection”并使用该方法检测所碰物体tag是否为“Collection”来执行此操作
