    Hello guys,

    Base Informations:
    Unity version 2022.1.14f (workes nice for me till this point)
    Mathematics v1.2.6
    using Unity.Mathematics is implemented in script

    The Problem only these 3 options are shown:
    Unity.Mathematics.Random.CreateFromIndex
    Unity.Mathematics.Random.Equals
    Unity.Mathematics.Random.ReferenceEquals

    is this a bug or do i missing something?

    Thanks in advance

    What do you mean by this?

    You should show your usage. You don't state if you're trying to figure out how to use it or if you've used it correctly in the past but now something has gone wrong with your setup. Are you asking how to use it?

    I presume you've created an instance of the Random class and are calling from that? CreateFromIndex is Static so it's called from the Type.

    you're not supposed to use mathematics. Delete that line. Random is built into unity engine

    Well read the docs closer. You're using them like static functions when they're not. You need to make an instance of Unity.Mathematics.Random first, as @MelvMay already pointed out.

    You already said that in your first post but hey, don't read/reply to what I wrote. ;)

    I would strongly suggest learning the basics of C#. You should understand that to access methods that are not Static, requires you to create an instance of the type. Static methods are accessed by the Type without the need for an instance as I stated in my first reply.

    Regardless, it should be pretty clear you do:
    Code (CSharp):
    1. var myRandom = new Unity.Mathematics.Random();
    2. myRandom.NextFloat();
