unity3d游戏开发之发射子弹的源代码.doc

今天讲了发射子弹并让子弹把墙打坏，并让打出去的子弹两秒后消失效果如下：详细代码如下：1. using UnityEngine;2. using System.Collections;3.4. public class Fire : MonoBehaviour 5.6. float speed = 5.0f;7. 8. public GameObject newObject;9. 10. 11. float firetima = 0.2f;12. float nexttime = 0.0f;13. 14. 15. void Update()16. 17. float a = -25 * Time.deltaTime;18. float x = Input.GetAxis(Horizontal) * Time.deltaTime * speed;19. float z = Input.GetAxis(Vertical) * Time.deltaTime * speed;20. transform.Translate(x, 0, z);21. if (Input.GetKey(KeyCode.Z)22. 23. transform.Rotate(Vector3.up * a, Space.Self);24. 25. if (Input.GetKey(KeyCode.X)26. 27. transform.Rotate(Vector3.down * a, Space.Self);28. 29. if (Input.GetButton(Fire1) & nexttime Time.time)30. 31. nexttime = firetima + Time.time;32. GameObject go = Instantiate(newObject, transform.position, transform.rotation) as GameObject;33. go.rigidbody.AddForce(0, 0, 1231);34. Destroy(go,2.0f);35. 36. 37. 38.39. 接下来，我们要做一个太空大战的小游戏具体实现效果是：1、我方点击鼠标左键或按空格键发射子弹，我方子弹连续发射2、敌方飞机和子弹自动运行，子弹每隔0.5秒向我方发射一颗3、我方飞机移动时，敌方子弹跟随我方飞机移动目前实现第一步代码部分代码如下：1. using UnityEngine;2. using System.Collections;3.4. public class Player : MonoBehaviour 5. float speed = -50.0f;6. 7. public GameObject Myplayer;8. 9. 10.11. 12. 13. void Update()14. 15. float a =Time.deltaTime;16. float x = Input.GetAxis(Horizontal) * Time.deltaTime * -speed;17. float z = Input.GetAxis(Vertical) * Time.deltaTime * -speed;18. transform.Translate(x, 0, z);19. 20. if (Input.GetButton(Fire1) )21. 22. /nexttime = firetima + Time.time;23. GameObject go = Instantiate(Myplayer, transform.position, transform.rotation) as GameObject;24. go.rigidbody.AddForce(0, 0, 1231
