Unity官方实例教程 Roll-a-Ball
与unity的transform组件相处的挺久了,最近项目不太忙,决定好好打下unity的基础。那么从Roll-a-Ball这个简单游戏开始吧!
1.先创建一个球体游戏对象,改名为Player,transform值y=0.5,加上刚体组件,具体如下图:
其中脚本PlayerController.cs代码如下:
using UnityEngine; using UnityEngine.UI; public class PlayerController : MonoBehaviour { public float speed; public Text countText; private float count; // Use this for initialization void Start () { count = 0; setCountText(); } // Update is called once per frame void FixedUpdate () { float moveH = Input.GetAxis("Horizontal"); float moveV = Input.GetAxis("Vertical"); Vector3 move = new Vector3(moveH,0.0f,moveV); GetComponent<Rigidbody>().AddForce(move * speed * Time.deltaTime); } void OnTriggerEnter(Collider other) { Debug.Log("碰撞"); if (other.gameObject.tag == "PickUp") { other.gameObject.SetActive(false); count++; setCountText(); } } private void setCountText() { countText.text = "Count:" + count; } }
2.创建一个平面,改名为Ground,具体如下图:
3.摄像机,让相机简单跟随游戏对象,为Main Camera挂一个脚本CameraController,代码如下:
using System.Collections; using System.Collections.Generic; using UnityEngine; public class CameraController : MonoBehaviour { public GameObject player; private Vector3 offset; // Use this for initialization void Start () { offset = transform.position; } // Update is called once per frame void LateUpdate () { transform.position = offset + player.transform.position; } }
4.创建被抓取的立方体,通过预制体来做,先创建一个立方体,transform中rotation三个值都设为45,挂上脚本Rotator,代码如下:
using System.Collections; using System.Collections.Generic; using UnityEngine; public class Rotator : MonoBehaviour { // Use this for initialization void Start () { } // Update is called once per frame void Update () { transform.Rotate(new Vector3(15,30,45) * Time.deltaTime); } }
然后将这个cube拖到Assets下面预制体文件夹中,再通过这个预制体来创建多个。
6.再简单的添加一个计分板,create-UI-Text,并拖拽到Player的countText参数下,调整合适位置
Ground加墙什么的可以自由发挥,都比较简单。。。
比较重要的是理解Rigidbody,Collider,Is Trigger这三个东西,具体看这个总结:http://blog.csdn.net/monzart7an/article/details/22739421
