[英]call method from another script C# Unity3d
我想在銷毀對象時調用另一個腳本方法(星號),以下是我到目前為止已完成的代碼,在“ tim.stars”行出現錯誤(空引用),有什么建議我做錯了嗎? 這是我的代碼。
using UnityEngine;
using System.Collections;
public class clear : MonoBehaviour {
// Use this for initialization
void Start () {
GetComponent<ParticleSystem> ().emissionRate = 0;
}
// Update is called once per frame
void Update () {
if (Input.GetMouseButtonDown (1)) {
GetComponent<ParticleSystem> ().Emit (10);
}
}
void OnParticleCollision(GameObject obj)
{
if (obj.gameObject.tag == "fire1") {
Destroy (obj, 5.0f);
TimingForIndust2 tim = GetComponent<TimingForIndust2> ();
tim.stars ();
}
StartCoroutine (TestCoroutine());
}
IEnumerator TestCoroutine(){
yield return new WaitForSeconds(8);
Application.LoadLevel (25);
}
}
這是我的第二個腳本TimingForIndust2
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using MadLevelManager;
public class TimingForIndust2 : MonoBehaviour {
public Transform TimingBar;
public Transform TextIndicator;
public Transform TextRemaining;
[SerializeField] private float currentAmount;
[SerializeField] private float speed;
// method to reduce the time continously
void Update () {
if (currentAmount > 0) {
currentAmount -= speed*Time.deltaTime;
TextIndicator.GetComponent<Text>().text=((int)currentAmount).ToString()+"s";
TextRemaining.gameObject.SetActive(true);
} else {
TextRemaining.gameObject.SetActive(false);
TextIndicator.GetComponent<Text>().text="TimeUP";
Application.LoadLevel (62);
}
TimingBar.GetComponent<Image> ().fillAmount = currentAmount / 60;
}
public void stars()
{
if (currentAmount > 45.0f) {
MadLevelProfile.SetLevelBoolean (MadLevel.currentLevelName, "star_1", true);
MadLevelProfile.SetLevelBoolean (MadLevel.currentLevelName, "star_2", true);
MadLevelProfile.SetCompleted (MadLevel.currentLevelName, true);
} else if (currentAmount > 20.0f && currentAmount < 29.0f) {
MadLevelProfile.SetLevelBoolean (MadLevel.currentLevelName, "star_1", true);
MadLevelProfile.SetLevelBoolean (MadLevel.currentLevelName, "star_2", true);
MadLevelProfile.SetCompleted (MadLevel.currentLevelName, true);
} else if (currentAmount > 2.0f && currentAmount < 19.0f) {
MadLevelProfile.SetLevelBoolean (MadLevel.currentLevelName, "star_1", true);
}
}
}
通過閱讀注釋,您必須找到帶有GameObject.Find
的Timer
,然后從中獲取組件。 您不能每次都發生碰撞時執行此操作。 您必須將其緩存在Start()
函數中一次,然后重新使用它。
我還在新代碼中緩存了ParticleSystem
。 此外,不要使用obj.gameObject.tag == "fire1"
直接比較標簽,而應使用CompareTag
函數比較標簽。
這應該可以解決您的問題。 現在,您的工作是緩存附加到TextIndicator
腳本的Text
組件,該腳本正在TimingForIndust2
腳本中的TimingForIndust2
函數中調用。
using UnityEngine;
using System.Collections;
public class clear : MonoBehaviour {
TimingForIndust2 timingForIndust2;
ParticleSystem particles;
// Use this for initialization
void Start () {
particles = GetComponent<ParticleSystem> ();
particles.emissionRate = 0;
GameObject tempObj = GameObject.Find("Timer");
timingForIndust2 = tempObj.GetComponent<TimingForIndust2>();
}
// Update is called once per frame
void Update () {
if (Input.GetMouseButtonDown (1)) {
particles.Emit (10);
}
}
void OnParticleCollision(GameObject obj)
{
if (obj.CompareTag("fire1")) {
Destroy (obj, 5.0f);
timingForIndust2.stars ();
}
StartCoroutine (TestCoroutine());
}
IEnumerator TestCoroutine(){
yield return new WaitForSeconds(8);
Application.LoadLevel (25);
}
}
