System of random items

Hello again I'm doing the racing game and am trying to do on my map to pick up items but I want mariokart style that I picked up a box and inside it was the system of random selection I've ever even imagine how I can do that, I'm wanting to do an arraylist and my items will be on them and send randonizar this list to get a random value, could someone help me please. Thanks I await answers.

Obs:I am using C#.

Thanks.

 

Something like this will work for you.

Code (csharp):

1.  
2. Random random = new Random();
3. var myItem = myItemArray[random.Next(myItemArray.Length)];

When you need a percentage chance for every item, there are different approaches. For example:

Thanks Marrrk. Now enjoy it as I could make the system of positions, for example display on my screen that I'm in first, second or third place could help me please?
Thanks.

 

Marrrk. Desculpe mas o seu código não funcionou e eu precisava dele em C# se poder coloca variavel para mim tambem pois não estou sabendo como declarar em C# uma array ja olhei na documentação da unity mas lá só mostro como é a declaração em javascript poderia por favor me ajudar?

 

To your last post (I hope i did understand it, I dont speak any portuguese):

You dont need an array if you want to dynamically add items into the list of available items (also its eadier to explain everything with a list).

Declare and define a List of Items;

Code (csharp):

1. List<UsableItem> myItems = new List<UsableItem>();
2. myItems.Add(new HomingMissile());
3. myItems.Add(new Missile());
4. myItems.Add(new Shield());
5. myItems.Add(new Booster());
6. myItems.Add(new SuperBoost());

If you want this as an Array:

Code (csharp):

1. UsableItem[] myItems = UsableItem[]
2. {
3.   new HomingMissile(),
4.   new Missile(),
5.   new Shield(),
6.   new Booster(),
7.   new SuperBoost()
8. };

Alternative:

Code (csharp):

1. UsableItem[] myItems = UsableItem[5];
2. myItems[0] = new HomingMissile();
3. myItems[1] = new Missile();
4. myItems[2] = new Shield();
5. myItems[3] = new Booster();
6. myItems[4] = new SuperBoost();
7.  

Everything else in my code should be usable as it is.

To your first post:

I would nsuggest that you look into the GUI classes and simply display a texture with the position of the player according to the current placing of the player. Please elaborate your problem.

 

Sorry Marrrk, I am Brazilian and I ended up writing in Portuguese my problem that was up there but what I was trying to say is that I needed the example in C # and was not finding a good example in the documentation of unity, but had imagined that to was equal to an ArrayList as it is in java. But thanks! =)
