How to load a new level when the game is finished?

(I ask this question on the unity answers page but it didn't work. )

Hello! I am working on a game where you have 4 holes and 4 balls. In every hole must go in a ball, if that is done i want to load a new scene. But i really dont know how i make this. Can someone give my a script for this? I am searching now 2 months for this problem but i cant find a solution. (I write in C#)

Btw: maybe something with a trigger system?

 

I don't think anyone is going to just write you a script. I will point you in the right direction though. Set up some variables so you know when all of the holes have been filled. Once that has happened use Application.LoadLevel() to load your next level. Again, I could write the script for you, but it wouldn't teach you anything.

Look into OnTriggerEnter and Application.LoadLevel; you also might want to look into using boolean variables if you are not familiar with them.
Good luck!

 

Hello, thanks for your reaction, I am new to programming in C# so i dont have really a lot of experience. I can make it with one ball and one hole but with 2 or 4 not. Thats why i ask for a script , but what you said here above that thought i too but i dont know more than that...

 

Let me see what I can do about writing a small example script on how I would approach your problem. Give me half an hour.

 

I haven't actually tested this, but if it doesn't work it is at least really close to something you can use. Attach this first script to your holes.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class HoleTrigger : MonoBehaviour {
5.  
6.     public int index;
7.  
8.     public TriggerAndLoad triggerAndLoad {
9.         get{
10.             return GameObject.FindObjectOfType<TriggerAndLoad>();
11.         }
12.     }
13.  
14.     void OnTriggerEnter(Collider col) {
15.         triggerAndLoad.TriggerHole(index);
16.     }
17.  
18. }
19.  

Attach this script to any object in the scene that isn't going to be destroyed. I usually handle things like this with a "Game Master" object that just exists for the purpose of holding things like this.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class TriggerAndLoad : MonoBehaviour {
5.     public bool[] holeTrigger = new bool[4];
6.  
7.     public void TriggerHole(int index) {
8.         holeTrigger[index] = true; //Set the hole trigger to true
9.  
10.         //Check if all holes have been triggered
11.         if(AllTriggered)
12.             Application.LoadLevel(0); //Modify this index to whichever level you want to load.
13.     }
14.  
15.     //This method will iterate through each of the triggers in the array and return false if any of them are not true.
16.     public bool AllTriggered {
17.         get{
18.             bool b = true;
19.             foreach(bool bX in holeTrigger){
20.                 if(!bX)
21.                     b = false;
22.             }
23.             return b;
24.         ;}
25.     }
26.    
27. }
28.  

If you have any issues with implementation. Let me know. Best of luck to you!

 

First, thanks for sending me a script, the script has no erros, but i have attach the HoleTrigger script to al the 4 holes and they are trigger and the TriggerAndLoad to the 4 balls, and i added by application.loadlevel(); a new scene but it dousn't work

 

No no no...you only want one TriggerAndLoad.cs in the scene. Don't put it on the balls haha. If you have more than one present in the scene you are gonna have issues.

 

Also, you need to set up the indices on your hole trigger scripts. One should have an index of 0, another should be 1, then 2, then 3. If you don't set it up like that it will not work. I guess I should have explained that as well. You can change the index via the public variable in the inspector.

 

ow, but where must i added the script?

 

Make a new GameObject in the hierarchy and call it "Game Master" or something like that. Attach TriggerAndLoad to that object. Do not attach it to the balls. You only want one of them. Think of it like this...TriggerAndLoad.cs is a server and the 4 instances of the hole trigger script are clients that communicate with it. They all communicate with the same instance of the TriggerAndLoad script.

 

I am a little confused, i have made a cube in the hierarchy and called it Game Master and attached it with the TriggerAndLoad script. But it still dont work

 

I think i'm doing something wrong

 

lol, I did tell you I didn't test the script. Let me test it from my end and see if I can get it working.

 

I can't say if you are or not as I didn't test the script. I know there are no errors and I kind of just assumed it would work without ever testing it. Let me set up a quick scene and test it myself.

 

Ow haha, I'm sorry, i am a 14 year old boy that lives in the netherlands so my english is not the best

 

Btw i really really thank you, you will help me

 

It's fine on my end @Barft . Here's a few things to consider:

1. Balls need Rigidbodies
2. Holes need triggers in them
3. Indices of HoleTrigger.cs have to be set up at 0, 1, 2, and 3
4. Make sure there is only one instance of TriggerAndLoad.cs in the scene. Make sure you removed it from your balls.

Please see the attached unity package for proper usage

 

I dont can view them, dont have permissions

 

Ow, i got it

 

That scene should just keep reloading over and over when you press play. That means it is working. I didn't change the code at all. I just set up the scene properly

 

1. Balls nodig Rigidbodies
2. Gaten moeten triggers in hen
3. Indices van HoleTrigger.cs moeten worden ingesteld op 0, 1 , 2 , en 3
4. Zorg ervoor dat er slechts één exemplaar van TriggerAndLoad.cs in de scène . Zorg ervoor dat u deze verwijderd uit je ballen

What for an object is the game master?

 

It's just an empty GameObject. No cube, no sphere, no mesh. Just an empty object with the script attached to it.

 

IT WORKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

I lOVE YOU, really man, i am searching for 2 months and i finally got it!!!!! I really really really want to thank you!!!

 

No worries. Just stick with it and you'll catch on. It's good to start young like you are. Just keep at it and try not to get discouraged. Programming isn't easy and it takes years to get comfortable with it. Best of luck in all of your future endeavours!

 

@Barft, based on what I read, I'd recommend you watch C# and Unity tutorial videos. I'm not sure how well your English comprehension skills are, as you mentioned you're a 14 year old boy in the Netherlands, but it's at least worth watching the videos and downloading the sample coding and test out what everything does to understand what is happening.

It helps to take the Unity scripts from the tutorials and change minor things in them to further understand what scripts do in Unity.

Unity scripting tutorials:

You can look for a local Unity meetup group and see if you can meet with people in the Netherlands:

Finally, if you get stuck, the forums are a great resource for knowledge as you've already seen. Also, remember to never give up. You'll find the solution eventually. All the best.

 

Thanks all

 

Ow i got one problem. 3 of the 4 elements be active when the ball fall in the hole, but one does nothing. Do you know what the problem is?

 

And it gives the error: Index is out of range

 

Are your indices set as 0, 1, 2, and 3? The length of the array is 4, but zero is included so the last index in the array is actually 3.

 

o ok, i fixed it. Thanks!

 

Hi guys, i got a new problem. But this time with GUI's. I have made a script and it looks like:

float timeRemaining = 35;
public Texture2D menuImage;
public int width = 100;


void OnGUI () {
if (timeRemaining > 0) {
GUI.DrawTexture(new Rect(Screen.width-100,20,70,28), menuImage);
}
}

It set a image in de scene, it works but the image height is really low and the width is normal. What is the problem?

 

OnGUI is the old system, if you're just starting out I recommend you use the new UI system.

https://unity3d.com/learn/tutorials/modules/beginner/ui

it's more "in scene" setup and less code for the basic stuff.

 

Ok, thanks

 

Hello , i didn't found the answer for my problem, can you please have a look to my new script:

float timeRemaining = 35;
public Texture2D menuImage;
public int width = 100;


void OnGUI () {
if (timeRemaining > 0) {
GUI.DrawTexture(new Rect(Screen.width-100,20,70,28, menuImage.width, menuImage.height), menuImage);
}
}

I have one thing added, namely menuImage.width, and menuImage.height. Thats the solution for the problem. But unity gives some errors, and i don't understand what is wrong.
