Virtual reality without sick bags — Overcoming motion sickness in VR game development

VR is becoming increasingly prevalent, with the release of newer, more accessible hardware being announced, such as the Oculus Quest 2 on 13th October 2020, which offers a wireless VR experience while being priced significantly lower than its competitors and predecessors.

Finding which is the shorter 2D angle

Calculating the shorter angle of rotation in 2D

Here’s a really simple math problem in 2D games development that has a surprisingly complex solution. If I were to give you angles a and b, how would you calculate 1) the direction — that is, clockwise being positive; and anti-clockwise being negative — and 2) magnitude of the shorter angle of rotation from a to b?

Main angle question
We want the angle in green.

When you visualise it, both values seem so obvious; which was why I was so surprised I couldn’t figure it out. On the surface, it seems really simple — if you just take b – a, doesn’t it give you the solution?

Static variables explained, in Java

Static variables, explained (using Java)

One of the more complicated concepts that beginning programmers have trouble grasping is static variables. This is in part because static variables work in a way that is quite opposite to how classes and Object-Oriented Programming (OOP) work.

Since examples work wonders in explaining concepts, here’s a use-case in Java that will help to illustrate the concept. Don’t code in Java? No problem. OOP concepts are (mostly) the same across programming languages.
