小球酷跑游戏制作过程

提示：文章写完后，目录可以自动生成，如何生成可参考右边的帮助文

提示：以下是本篇文章正文内容，下面案例可供参考

设计背景颜色：

代码如下（示例）：

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

public class cameraControl : MonoBehaviour {
    public GameObject player;
    private float offset_camera;
	void Start () {
        offset_camera = gameObject.transform.position.x - player.transform.position.x;
	}
	// Update is called once per frame
	void Update () {
        FollowCameraMove();
    }
    void FollowCameraMove()
    {
        gameObject.transform.position = new Vector3(offset_camera +     player.transform.position.x, gameObject.transform.position.y,gameObject.transform.position.z);
    }
}

小球设置刚体并应用代码

代码如下（示例）：

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

public class playMove : MonoBehaviour {
    public Rigidbody rd;
    public float speedAutoMove = 5;
    public float speedMoveUpandDown = 20;
	void Start () {
        rd = gameObject.GetComponent();
	}
	
	void Update () {
        PlayerAutoMove();
        PlayerMoveUpandDown();

    }
    private void PlayerAutoMove()
    {
        rd.AddForce(Vector3.right*speedAutoMove);//前进
    }
    private void PlayerMoveUpandDown()
    {
        float v = Input.GetAxis("Vertical");//上下运动
        rd.AddForce(v*Vector3.up*speedMoveUpandDown);//给一个上下的力量
    }
}

##3.设置障碍物自动生成代码
先设置预制体

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

public class BarrierControl : MonoBehaviour {
    public GameObject player;
    public GameObject BarrierPre;
    public GameObject CurrentBarrier;
    public int BarrierInterval = 10;
	
	void Start () {
		
	}
	
	void Update () {
        AutCreatBarrier();

    }
    public void AutCreatBarrier()
    {
        if(player.transform.position.x>CurrentBarrier.transform.position.x)
        {
            //生成新的障碍物
            float targetX = CurrentBarrier.transform.position.x+BarrierInterval;
            float targetY = RandomBarrierPositionY();
            Vector3 targetPos = new Vector3(targetX,targetY,0);
            GameObject g = Instantiate(BarrierPre,targetPos,Quaternion.identity);
            g.transform.localScale = new Vector3(g.transform.localScale.x, RandomBarrierSizeY((int)g.transform.position.y),g.transform.localScale.z);
            CurrentBarrier = g;
        }
    }
    public float RandomBarrierSizeY(int y)
    {
        int yAbs = Mathf.Abs(y);
        if(yAbs==0)
        {
            return 6;
        }
        else
        {
            return (3 - yAbs) * 2 - 1;
        }

    }
    public float RandomBarrierPositionY()
    {
        int r = Random.Range(-3,3);
        return r;
    }
}

三.效果图

以上就是今天要讲的内容，本文仅仅简单介绍了unity的小球酷跑的制作。
