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*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.****.net/monzart7an/article/details/22739421
