These are FIVE TRICKS that my colleagues and I have learnt from one academic year or REMOTE TEACHING in HIGHER EDUCATION. ๐Ÿ“š๐ŸŽ“

Every class is different, and every lecture has their own teaching style. But feel free to share this thread if you think it might help someone!

If you are using PowerPoint with a second monitor, you can actually resize the "Presenter View" window:

1โƒฃ๐Ÿ–ฅ๏ธ
๐Ÿ”ดShared screen with slides

2โƒฃ๐Ÿ–ฅ๏ธ
๐Ÿ”ตPresenter view with notes
๐ŸŸขMS Teams chat

So you can share your screen, see your notes & read questions!

Every time a student present their work in front of the class, I invite everyone to clap. ๐Ÿ‘

A remote alternative is to encourage students to raise and lower their hands on MS Teams quickly.

Getting some good lighting from your home office can be a challenge.

There is a cheaper alternative to buying a ring light: put a white or warm yellow image full screen!

It will add a gentle light to your face!

It is important to have several breaks during your classes. Especially if they are taking place online!

Sharing your screen with a PowerPoint loading animation is a good way to make sure students are getting back on time! โณ
5โƒฃ MS Teams Polls ๐Ÿ’ฌ

One feature that MS Teams is sadly lacking, is the ability to run polls inside a meeting.

Fear not! You can write a series of messages, and asking your students to put a thumbs up "vote" the option they prefer. ๐Ÿ“Š

Just keep in mind it is not anonymous! ๐Ÿ‘๏ธ
If you know any other trick that works for your classes, feel free to share them in a comment! ๐Ÿ‘‡๐Ÿ‘‡๐Ÿ‘‡

I would love to hear moreโ€”and learnโ€”from other colleagues! โ˜บ๏ธ

BEHAVIOUR TREES are the cornerstone of ARTIFICIAL INTELLIGENCE for #gamedev.

But they can be difficult to "grow". ๐ŸŒฑ

I have selected FIVE rather approachable papers that use EVOLUTION to grow behaviour trees AUTOMATICALLY, so you don't have to. ๐ŸŒฒ

Let's start with...๐Ÿ“

Fifty years have passed since CONWAY'S GAME OF LIFE firstly appeared on a column called "Mathematical Games" on @sciam.

While most Programmers & Computer Science enthusiasts are familiar with it, not many know that the game is actually TURING COMPLETE.

Let's see why. โ  โ ต

๐Ÿงต๐Ÿ‘‡
The quickest way to prove that a system is TURING COMPLETE is to show that it allows for the constructions of LOGIC GATES. ๐Ÿ–ฅ๏ธ

So, let's see how the ๐—”๐—ก๐——, ๐—ข๐—ฅ and ๐—ก๐—ข๐—ง gates can actually be constructed in Conway's Game of Life...
Firstly, we need to find a way to encode binary signals.

One very popular choice is to use a stream of GLIDERS. The so-called GOSPER GLIDER GUN can generated a new glider every 30 generations. ๐Ÿ”ซ

Hence, receiving a glider every 30 generations counts as a "1".

If you are interested in learning AI and how it can be used in #gamedev, you should start with BEHAVIOUR TREES! ๐ŸŒฒ๐Ÿง 

As the cornerstone of game AI, BTs are used in:

โ€ข Halo 2 ๐Ÿช–
โ€ข Bioshock ๐Ÿ’‰
โ€ข GTA V ๐Ÿš—
โ€ข Faรงade ๐Ÿˆ
โ€ข Alien: Isolation ๐Ÿ‘ฝ

Let's see how they work! ๐Ÿ‘‡

Many of you are familiar with FINITE STATE MACHINES: the most popular pattern for character controllers.

While FSMs are graphs, BTs are (unsurprisingly!) trees. ๐ŸŒฒTheir leaves are the ACTIONS ๐Ÿฆพ and PERCEPTIONS ๐Ÿ‘๏ธ your agents can perform and sense.
Each node in a BT can be in any of the three following states:

โ€ข โœ”๏ธ SUCCESS: the node was executed successfully
โ€ข โŒ FAILURE: the node could not be completed
โ€ข โณ RUNNING: the node is still being executed

Most #gamedev are familiar with A*, the most used pathfinding algorithm in games.

โš ๏ธ But did you know that there's a very common scenario in which A* DOES NOT find the shortest path? ๐Ÿ˜ฑ

Let's see why A* won't work in "Portal", and how we can fix it!

๐Ÿงต
All pathfinding algorithms work by iteratively exploring nearby cells in the grid.

โฌ…๏ธ Breadth First Search explores them in the order in which they are discovered.

โžก๏ธ Dijkstra's Algorithm, instead, keeps exploring the SHORTEST PATH FIRST.

(gif by @redblobgames)
That is also why Dijkstra's algorithm is sometimes referred to as the SHORTEST PATH FIRST algorithm.

Ultimately, it is that property that ensures its OPTIMALITY (= it will always find the shortest path between any two points).

One of the best ways to improve your creativity isโ€”paradoxicallyโ€”to design with constraints.

Perhaps this is why the #pico8 community never failed to amaze me with their tiny creations.

So, here's a list of PICO-8 DEMAKES, starting with possibly the best one ever made...

Turns out 2020 wasโ€”for many of usโ€”one of the worst years on record.

If you are feeling stressed and need somewhere to escape for a little bit, this is a thread about some short, calming games that I hope will help you relax.

Starting with...

"A Short Hike" is without any doubt the best indie title of the year. ๐Ÿ”๏ธ๐Ÿฆ

@adamgryu has truly crafted something that can soothe your soul for a good few hours.

"Kind Words" is a game like no other. ๐Ÿ’Œ๐Ÿค—

You can write about your own issues, and read anonymous replies from other players.

It's warming and empowering. @popcannibal created one of the few experiments on empathy that actually worked.
