Basic trigonometry for game development

Introduction

two distinct points (for example, a game object position and the mouse cursor position) in an area can always be two corners of a Right Triangle (Triângulo-retângulo in ptbr). A triangle has three sides: The Hypotenuse, the Adjacent and the Opposite.

The distance between two points in the X axis corresponds to the Adjacent side of a triangle, The distance between two points in the Y axis corresponds to the Opposite side of a triangle.

The Hypotenuse is the shortest distance between the two points.

This means we can use trigonometry to handle many interactions between objects when programming visual stuff.

Кодирование строк со словарём и обработка запроса без декодирования строк
===Мотивация
Пользователи часто используют тип данных %%String%% для хранения повторяющихся строковых значений. Мы всегда говорим, что это - антипаттерн и рекомендуем либо вручную писать вместо строк числовые идентификаторы, либо использовать %%Enum%%, либо использовать внешние словари. Но есть причины, по которым такой сценарий использования будет продолжать использоваться, и нам необходимо к нему адаптироваться.

Ninja support for CLion IDE

Ninja support for CLion IDE (working with newer versions of clion)

This script enables Ninja-powered builds in CLion IDE by wrapping around CMake, which it uses. See my blog post for details.

A short tutorial on how to use Vault in your Ansible workflow. Ansible-vault allows you to more safely store sensitive information in a source code repository or on disk.

Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.
