How do I OrderBy float size in an array?

Questions & Answers

Hello I am attempting to arrange an array that uses random numbers before sorting them by size in order to then us them based on their order. This is to create a simplistic randomisation for an attack pattern.

The issue:
I have to use random numbers so I need to be using namespaces; UnityEngine for the Random number generation and System.Linq in order to use OrderBy. I cannot use Systems namespace which contains “Array.Sort(Array);” which I know would be easier however does not work with UnityEngine for some reason, elaborate on why this is as well please.

I have got the Orderby code, however I cannot find any documentation on OrderBy anywhere so I cannot find what is required to put instead of the question marks of the code shown below.

I have tried searching around a lot and I have finally given up, code is as shown below, if anyone has a reference to what I am looking for, please share :smiley:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using System.Linq;

float randomOrder1;
float randomOrder2;
float randomOrder3;
float[] randomOrder;

IEnumerator FireThreeAttack()
{
    
    while (randomOrder1 == randomOrder2 || randomOrder1 == randomOrder3 || randomOrder2 == randomOrder1 || randomOrder2 == randomOrder3 || randomOrder3 == randomOrder1 || randomOrder3 == randomOrder2)
    {

        randomOrder1 = randomOrder1;
        randomOrder2 = randomOrder2 + 1.1f;
        randomOrder3 = randomOrder3 - 1.2f;

    }

    randomOrder = new float[] { randomOrder1, randomOrder2, randomOrder3 };

    randomOrder.OrderBy(randomOrder => randomOrder.???????).ToArray(); //what do I put here?

    if (randomOrder[0] == randomOrder1 || randomOrder[0] == randomOrder2 || randomOrder[0] == randomOrder3)//this will fire the attack off in the given order, I will change this later to be a while loop to be cleaner but for now I just need the information for the order sorting and I can take it from there, but if anyone spots anything wrong here let me know :D
    {

        if (randomOrder[0] == randomOrder1)
        {

            attackBlockMainAnim.SetBool("Fired?", true);

        }else { }

        if (randomOrder[0] == randomOrder2)
        {

            attackBlockLeftAnim.SetBool("Fired?", true);

        }else { }

        if (randomOrder[0] == randomOrder3)
        {

            attackBlockRightAnim.SetBool("Fired?", true);

        }else { }

    }

Your code is very confusing, and messy. I have no idea what you’re doing… However, the LINQ methods are well-documented in the C# docs. You need to use lambda expressions, which are confusing however. Here’s a simple array sort which you can use using LINQ. (Hopefully you can implement this correctly in your project):

float[] myArray = new float[] { 0.4f, -1.3f, 34f };

// mySortedArray looks like: -1.3, 0.4, 34
float[] mySortedArray = myArray.OrderBy(x => x).ToArray();
