Every now and then I see people talking about the difference between VISUAL SCRITPING and CODING.

So let me break this down for you.

Visual scripting ๐—œ๐—ฆ coding! ๐Ÿ‘จโ€โš–๏ธ

And this is why... ๐Ÿงต๐Ÿ‘‡
One of the most common criticism against visual scripting is that it finds an audience with novel or unexperienced developers.

This is often correct.

But the bit that is missing is that many of those "unexperienced developers" are actually VERY experienced artists & designers.
Visual coding removes one of the most challenging first steps to get into coding: getting the syntax right.

Making a programming language more accessible is not a bad thing.

Especially in #gamedev, this has allowed many artists to bring their ideas to life.
While I *personally* find visual scripting slower and somewhat cumbersome to use, I see so much potential in it!

But please, refrain yourself from claiming that people using visual scripting tools are not coders or programmers.

They are: you are just doing things the hard way.
So please, do not gatekeep people from learning how to code in a way that is effective for them.

Or someone might say the same to you. Because after all, you are not a REAL programmer if you are not using punched cards.
So let's see if this is was clear enough.

Is visual scripting real coding? โ“

There are over 2 BILLION people in the world living with a disability.

And a significant percentage of them are struggling to play games. ๐Ÿšซ๐ŸŽฎ

As part of the Global Accessibility Awareness Day #GAAD, this is a list of #gamedev resources to design more accessible games.

1โƒฃ COLOUR BLINDNESS ๐Ÿ‘๏ธ

There are approximately 300 million people in the word who are colour blind.

There are also many different types of colour blindness: DEUTERANOPIA is the most common, affecting the perception of red ๐Ÿ”ด and green ๐ŸŸข tones.
Games that are heavily relying on colour-coding to convey information are particularly affected!

Good compromises between aesthetics and accessibility can be seen in "FTL" & "Hue". Both games have the option to add patterns to colour-coding, which are generally easier to read. Image

This is a list of the FIVE (plus one!) measures of distance that every #gamedev should know!

๐Ÿงต๐Ÿ‘‡

Starting from the most well-known one...

1โƒฃ EUCLIDEAN DISTANCE ๐Ÿ“

Measures the distance between two points, using the Pythagorean theorem.

In Unity: Vector3.Distance(A,B).
2โƒฃ VECTOR DISTANCE ๐Ÿ“

Is a vector that starts from ๐Ÿ…ฐ๏ธ and goes to ๐Ÿ…ฑ๏ธ.
It is pretty handy in LINEAR ALGEBRA, as it can avoid Trigonometry.

It has a DIRECTION, meaning that ๐Ÿ…ฐ๏ธ-๐Ÿ…ฑ๏ธ is not the same of ๐Ÿ…ฑ๏ธ-๐Ÿ…ฐ๏ธ!

In Unity, you can calculate it by simply subtracting the two vectors!
3โƒฃ COSINE DISTANCE ๐Ÿ’ก

It measures the alignment of two UNIT VECTORS, as the cosine of the angle between them:

๐Ÿ”น A โ€ข B = +1 โ†’ fully aligned
๐Ÿ”น A โ€ข B = 0 โ†’ orthogonal
๐Ÿ”น A โ€ข B = -1 โ†’ opposite direction

Also known as DOT PRODUCT, it is very useful for shaders!

Let's talk about @unity3d, and the execution order of its event functionsโ€”such as ๐š‚๐š๐šŠ๐š›๐š and ๐š„๐š™๐š๐šŠ๐š๐šŽ.

Trust me when I say that ...IT'S WAY MORE COMPLICATED THAN YOU THINK. ๐Ÿ˜ฌ

Let's talk about NEURAL NETWORKS. ๐Ÿง 

Most of you are probably familiar with them. ๐Ÿง‘โ€๐Ÿ’ป

But not many know HOW they actually work andโ€”even more importantlyโ€”WHY they work. ๐Ÿ”ง

So, let's take a journey to understand what makes Neural Networks so effective... ๐Ÿ“Š

#ML #AI #NN

๐Ÿงต๐Ÿ‘‡
Let's start with a simple question...

โ“ What problem are NNs trying to solve? ๐Ÿค”

Generally speaking, NNs are trained on examples, to produce predictions based on some input values.

The example data (input + desired output) draws a curve that the NN is trying to fit.
In a nutshell, NNs areโ€”like most ML toolsโ€”a fancy way to fit the curves inherently generated by the examples used to train it.

The more inputs it needs, and the more outputs it produces, the higher the dimension of the curve.

The simplest curve we can fit is ...a line! ๐Ÿ˜…

This is a list of TEN (plus one) games that are "accidentally" TURING COMPLETE. ๐Ÿ–ฅ๏ธ

In a nutshell, when a game is Turing Complete you can use it to build a WORKING COMPUTER. ๐Ÿคฏ

If you are a parent: please don't underestimate games as a creative medium.

Let's start with...

๐Ÿงต๐Ÿ‘‡ ImageImageImage
1โƒฃ Minecraft โ›๏ธ

Unsurprisingly, @Minecraft is indeed Turing Complete. ๐Ÿ–ฅ๏ธ

This is possible thanks to the so-called REDSTONE CIRCUITS, which allow to build simple logic gates. ๐ŸŸฅ

And if you are really, REALLY committed ...you can even build a computer!

2โƒฃ Portal 2 ๐ŸŸ ๐Ÿ”ต

Yes. Everybody's favourite game is Turing Complete! ๐Ÿฅฐ

@anklejbiter used Portal 2 level editor to create a 3-Digit Binary Calculator. De-facto proving it can be used for arbitrary computation.
