Enabling UI panel after "x" amount of seconds

Hi Im new to scripting and I don't know much so please bear with me. Im making a game and I have a panel with text on it saying "game over". I also have a screen in the room that plays a video of a countdown when the player enters a trigger.



I want the UI panel with the text saying game over to enable when the video finishes and the countdown reaches zero. Does anyone know a simple way of doing this. Thanks a lot

 

What is the code for your countdown?

 

Use Time.deltaTime or Time.time depending on what you need, check unity documentation for a more specific description about those 2 (you will probably need Time.deltaTime anyway).
You basically could have a float variable "timer", and in the update reduce this variable by the time. When timer is 0 you could make the UI panel appear. Or do the other way around, and have the variable timer += Time.deltaTime and if timer is higher than what you need, something happens...

 

You would use a coroutine
https://docs.unity3d.com/ScriptReference/WaitForSeconds.html

 

Its not code its just a video of a countdown

 

I looked at the documentation but I cant wrap my head around it. Im new to code and i just dont see what I would write to get what I want

 

When you start the video of countdown you start the coroutine. Something like this:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class WaitForSecondsExample : MonoBehaviour
5. {
6.   Gameobject gameoverPanel;
7.  
8.   Void StartVideo ()
9.   {
10.      //your code where you start your
11.      video
12.     StartCoroutine(EnableGameoverPanel ());
13.   }
14.  
15.   IEnumerator EnableGameoverPanel()
16.     {
17.         yield return new     WaitForSeconds(115);//wait for 115 seconds (1:55minutes as your video)
18.  
19.         gameoverPanel.SetActive(true);
20.     }

 

Sorry for being annoying but this is what I currently have with the addition of your script. So basically its a screen that plays static and when the player walks up to it and enters the trigger it plays a second video by destroying the screen in front.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5. using UnityEngine.UI;
6.  
7.  
8. public class destroy : MonoBehaviour {
9.     public bool destroyOtherObject, showObject;
10.     public GameObject objectToDestroy, objectToShow;
11.     GameObject gameoverpanel;
12.  
13.     void OnTriggerEnter (Collider other)
14.     {
15.        
16.      StartCoroutine(EnableGameoverPanel ());
17.     }
18.  
19.     IEnumerator EnableGameoverPanel()
20.     {
21.         yield return new     WaitForSeconds(115);
22.         gameoverpanel.SetActive(true);
23.     }
24.  
25.     {
26.         if(other.tag == "Player") {
27.             if (destroyOtherObject){
28.                 Destroy (objectToDestroy);
29.             }
30.             if (showObject) {
31.                 objectToShow.SetActive (true);
32.             }
33.         }  
34.  
35.     }
36.  
37. }

I'm probably being really stupid but do you know why I'm getting this error

 

You forgot void OnTriggerEnter, which should be added on 24th line.
EDIT : You should have only 1 OnTriggerEnter.
Why there is no if statement on the 15th line?
Add the proper if statements on the first OnTriggerEnter and you shouldnt't have problems.

 

Okay so I basically want it so that when the player enters the trigger the countdown video starts playing and i also want the coroutine to start counting down when they enter the trigger. Im a complete noob how can I have both things happen when the player enters the trigger?

 

If you enter the trigger -> the countdown video start playing AND a coroutine starts.
tranos already told you how to do it, just carefully read the code he provided you and adjust it to your needs.

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5. using UnityEngine.UI;
6. public class destroy : MonoBehaviour {
7.     public bool destroyOtherObject, showObject;
8.     public GameObject objectToDestroy, objectToShow;
9.     GameObject gameoverpanel;
10.     void OnTriggerEnter (Collider other)
11.     {
12.         if(other.tag == "Player") {
13.             if (destroyOtherObject){
14.                 Destroy (objectToDestroy);
15.             }
16.             if (showObject) {
17.                 objectToShow.SetActive (true);
18.             }
19.         }
20.      StartCoroutine(EnableGameoverPanel ());
21.     }
22.  
23.     IEnumerator EnableGameoverPanel()
24.     {
25.         yield return new     WaitForSeconds(115);
26.         gameoverpanel.SetActive(true);
27.     }
28. }

Also some basics to get you started:

• Classes on C# Read it all! but to give you a quick view have this:

Code (CSharp):

1. public class Person
2. {
3.     // Public Field
4.     public string name;
5.  
6.     // Constructor that takes no arguments. You wont be using constructors in Unity unleass you have a class that doesn't inherit from MonoBehaviour or any other Unity Type, instead you would use Start() and Awake()
7.     //Constructors are called whenever you create a new instance of this class
8.     public Person()
9.     {
10.         name = "unknown";
11.     }
12.  
13.     // Constructor that takes one argument.
14.     // This is called "Constructor overloading" which means that you can create a "new Person()" either without passing a name or passing a name "new Person("James")
15.     public Person(string nm)
16.     {
17.         name = nm;
18.     }
19.  
20.     // Method
21.     public void SetName(string newName)
22.     {
23.         name = newName;
24.     }
25.    
26.     // Methods can also be overloaded
27.     public void SetName(string firstName, string lastName)
28.     {
29.         name = firstName + ", " + lastName;
30.     }
31. }

Code (CSharp):

1. public class Class1 : Monobehaviour
2. {
3.     public int publicField = 1;
4.     private int privateField = 2;
5.  
6.     public void Method()
7.     {
8.         int localVariable = 0;
9.         publicField = localVariable;
10.     }
11.  
12.     //Cannot be seen or used by someone else outside of this class
13.     private void OtherMethod()
14.     {
15.         //Can't access localVariable from Method(), it doesn't exist here
16.         //Can access class fields
17.         publicField = 5;
18.         privateField = 3;
19.     }
20.  
21.     private void ThirdMethod()
22.     {
23.         // You can call your own methods without restrictions
24.         Method();
25.         OtherMethod();
26.     }
27. }

Code (CSharp):

1. public class Class2 : Monobehaviour
2. {
3.     //public field of type Class1, set it on the editor by dragging a Class1 component to this field
4.     public Class1 otherClass;
5.  
6.     public void UsingClass1()
7.     {
8.         otherClass.publicField = 3; //You can set public class fields
9.         // privateField can not be accessed from here
10.         otherClass.Method(); // You can call public methods
11.         // localVariable of Method(), however, doesn't exist here
12.         //OtherMethod() and ThirdMethod can't be accessed from here
13.     }
14.  
15.     //Cannot be seen or used by someone else outside of this class
16.     private void OtherMethod()
17.     {
18.         //Can't access localVariable, it doesn't exist here
19.         //Can access class fields
20.     }
21.  
22.     private void ThirdMethod()
23.     {
24.         You can call your own methods without restrictions
25.         Method();
26.         OtherMethod;
27.     }
28. }

• Methods in C#

• Fields in C#

 

You definitely can't have this:

Code (CSharp):

1. public class Class2 : Monobehaviour
2. {
3.  
4.     // This is a method
5.     void Method1()
6.     {
7.         //Do things here
8.     }
9.    
10.      //This is nothing. It doesn't know to which method it belongs
11.     {
12.         // Code here
13.     }
14.    
15.      // You can't do this, there can't be two methods with the same name. They don't extend, just write it on the other one
16.      void Method1()
17.     {
18.         // Code
19.     }
20.  
21.     // You can overload it however. They should be similar on purpose like transform.Rotate(Vector3) and Transform.Rotate(Quaternion)
22.      void Method1(ParameterType parameterName)
23.     {
24.         // Code, now using the parameterName parameter
25.     }
26. }

 

OH MY GOD!! Thank you so much you are a legend you don't know how happy this made me when it worked
