picking random number from list

hi , I was trying to make a code , that picks one of these numbers (11,12,13,14) ,but it says errors like :

Assets\Sripts\RandomPick.cs(7,23): error CS0266: Cannot implicitly convert type 'float' to 'int'. An explicit conversion exists (are you missing a cast?)

and

Assets\Sripts\RandomPick.cs(7,23): error CS0029: Cannot implicitly convert type 'float[*,*,*,*]' to 'float[]'

what is bad ? code :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class RandomPick : MonoBehaviour
6. {
7.     float[] numbers = new float[11f,12f,13f,14f];
8.     int randomIndex = Random.Range(0, 3);
9.         // Start is called before the first frame update
10.     void Start()
11.     {
12.         float randomFLoatFromNumberst = numbers[randomIndex];
13.     }
14.  
15.     // Update is called once per frame
16.     void Update()
17.     {
18.        
19.     }
20. }

 

You're defining array incorrectly;
The arguments inside brackets are actually it's length.
float[4] is an array of 4 floats, where as float[11f, 12f, 13f, 14f] would be 4-dimensional array with float amount of elements, which is not allowed.

If you want to define an array, simply do it like so:

Code (CSharp):

1. float[] array = {1f, 2f, 3f};

 

thx , it kinda works . It says
UnityException: RandomRangeInt is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'RandomPick'.
See "Script Serialization" page in the Unity Manual for further details.
UnityEngine.Random.Range (System.Int32 min, System.Int32 max) (at C:/buildslave/unity/build/Runtime/Export/Random.bindings.cs:48)
RandomPick..ctor () (at Assets/Sripts/RandomPick.cs:8)

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class RandomPick : MonoBehaviour
6. {
7.     float[] numbers = { 11f, 12f, 13f, 14f };
8.     int randomIndex = Random.Range(1, 3);
9.     public float picked;
10.         // Start is called before the first frame update
11.     void Start()
12.     {
13.         float randomFLoatFromNumbers = numbers[randomIndex];
14.         picked = numbers[randomIndex];
15.      
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.        
22.     }
23. }

 

OH and it picks only 11

 

Move Random.Range to the Start. Also, you can do Random.Range(0, numbers.Length) to pick any index in the array.
