Unity入门操作_线性，球形检测_014

线性操作：伤害门。
生成游戏对象
using UnityEngine;
using System.Collections;
public class CreateCubes : MonoBehaviour {

// Use this for initializationvoid Start () {}float timer = 0.0f;// Update is called once per framevoid Update () {    timer += Time.deltaTime;    if (timer>3)    {        timer -= 3;        GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Cube);        obj.transform.position = new Vector3(0,0.5f,0);        obj.AddComponent<MoveDoor>();    }}

}
