Can you please give some advice on learning Unity?

Question

PHP

Good day, just don’t hit me hard :)
I want to start learning unity, but I understand that for this you first need to know at least 1 programming language normally, after googling I found out that you can write scripts in C# in unity; javascript and Boo. So tell a beginner, is there a fundamental difference in which language to write scripts in unity? Does this affect anything? And I also need your advice, which language would you advise to choose the first to learn?
PS I want to learn Unity to make games for android / ios :)
All the best, and thanks in advance for the answers.

Answer 1

The error is thrown because you are accessing the object context IN A STATIC METHOD.
But a static method is called WITHOUT CREATING an object (which is why it is static), that is, there is no object context (because there is no object itself), and therefore there is no way to access the internals of the object (which, I remind you, is not).

Answer 2

class CovertionPDF
{
    static $table = [];
    private $html;
    private $score;

    public static function getHTML($iOrder)
    {
        $order = self::getPaysystem($iOrder);
        self::$table = 'Hello world';
}
}

Answer 3

C#, it has the most materials, tutorials, articles. Most Unity3D examples available online are also written in it.
The scripting language, which is served there under the guise of JS, is not really such (google UnityScript vs Javascript), as a result, 99% of libraries and practices are of no use.
Boo is generally a rather rare beast, there are few (if any) textbooks on it, although the language, in principle, is not bad.
