EU Code Week: “How To” Session

As I’ve mentioned, we’ve got a big EU Code Week special coming up really soon.

And I’ve also mentioned that it’s not just for schools.

So if you happen to fall into one of these two categories: You’re in a School or You’re Not in a School; then have I got something for you!

“How-To” Session

On Tuesday, October 6th we’ll (myself and Dr. Steve Bunce, my co-host for the EU Code Week special) be hosting a special “How-To” session.

We’ll run through what the sessions are all about, how they’ll be structured, and then how best you can follow-along with the session from the comfort of your own home or the classroom.

#EveryoneCanCode

This session is for everyone, not just teachers. Not just parents. If you have an iPad and you want to give this coding lark a try, we’d love to have you!

It’ll be a chance to find out what we’ll be doing, ask some questions, and even offer input, if you like.

So sign up for the how-to session and get ready for EU Code Week!

EU Code Week: Not Just for Schools

Our sessions for EU Code Week aren’t just for classrooms! Just in case you were looking at all the materials, like the Using this Site in Class page, and thinking it was aimed at schools only, I added a new page: Using this Site at Home.

It’s a bit like our Coding at Home series: the video session will be designed for you to follow along, no matter the setting. If you can view the video on a big screen while you code along on a separate iPad that would be amazing, but if you only have one device at home, you just make due with what you have.
All this stuff, the site, the videos, the links, they’re all designed just to give you a bit of support to explore coding on your iPad.

Code Week, European or Otherwise

Wherever you are, you’re more than welcome to catch our sessions. Heck, we’ve got an American living in Ireland co-presenting with someone from the UK.

So if you want to follow along and try to embrace coding during EU Code Week, feel free to register your event, even if it’s your own household! We’ve got some instructions for doing so here.

So grab your iPad, sit back, relax, and get ready for some coding!

Welcome Back to School!

For many of you, you’re arriving back at school over these last few weeks (or days, even).

Hopefully your coding journey won’t end with the return to school. After all, you can apply coding to a lot of your schoolwork.

While we’ve been working on some cool stuff for teaching coding in the classroom — virtual or otherwise — you can still try your hand at our Coding at Home series.

Learning to Code

As we’ve seen with all of our playgrounds, coding isn’t always about coding for coding’s sake.

Sometimes we’re trying to explore our creative side with photos or sound. Other times we’re creating our own brand new reality. In our next session, we’ll show you our story-telling creation.

We touched on it way back in the beginning of our coding at home adventure, but only briefly.

I love telling stories, and doing so with a Swift Playground and a little bit of code is all the more fun!

We’re going to demo building a short story in which you can navigate an environment and become a part of the story, yourself. So be sure to stay tuned for our next coding session!

And, speaking of which…

Lastly…

Happy coding!

Video Lessons for Coding with Swift

📹

In case you’re missing our live sessions every week day terribly, keep in mind you can still visit any one of the videos we did over the last few months at Coding at Home.

This page has links off to the various YouTube playlists, where we’ve collected our library of content for:

  • Everyone Can Code Puzzles — relive the excitement of the Everyone Can Code Puzzles book from Apple and refresh your memory on all sorts of coding techniques and tricks
  • Lights, Camera, Code — a jaunt through using your iPad’s camera
  • Build your own Aquarium App — building on the Lights, Camera, Code stuff, we strike out on our own to build our own app using some of the same techniques we learned with our camera exercises
  • Augmented Reality — one of our huge hits, try your hand at augmenting your own reality with lunar landers, pinball games, you name it! Not a lot of coding knowledge required, but you’ll have a ton of fun!
  • And so many more…

You’ll re-live all the excitement of our live sessions with all the bloopers and feed issues as we (I hope) got better and better over time.

So while we’re building the next iteration of lessons/sessions, catch up on the old!

Coding at Home: Paused

Like yesterday, we’re taking a little hiatus. In the meantime, we have a ton of back catalog to trawl through. But no live coding today.

Under construction, sort of…?

Teaching Swift

If you’re a teacher, we added a post yesterday about teaching swift.

We started up a little community Slack instance to talk about how to teach Swift, give some pointers to great teachers of the language, and other coding tips and tricks.

I’d love to have you if you’re even remotely interested.

Next steps in your coding career

If you’re hungry for more coding, you could always make the next leap. If you have a Mac, you download Xcode and have a look at my course on Ted about Getting Started with Xcode. You’ll be building an app in no time*!

Good luck!

* No time actually works out to about 40 minutes. Give or take.

Coding at Home: July 16th, Press Pause

There will be no live coding today!

Okay, okay, stop crying. Please. You’re making a scene.

It’s embarrassing. Flattering, but embarrassing.

Okay. You good?

Everything okay?

Man, you’re really getting into this coding thing.

Recap

I hope you’ve been spending the evening and on into today coding your own messages to pass around to friends and family.

Maybe send out all your messages for the day on WhatsApp and Instagram and SnapChat and whathaveyou encoded and only give out the shift key later in the day.

To decrypt this you’ll need the time we usually broadcast at (Irish time, of course), and your Cipher playground. Good luck!

In the meantime, go check out some of our playlists to review coding lessons we’ve done here: Coding at Home.

Coding at Home: July 15th, Cipher

Join us today when we approach one of my all-time favorite playgrounds, Cipher, at 1pm, Irish time!

Recap: Sensor Arcade

We said goodbye to Sensor Arcade yesterday with a bit of cheat codes.

We’ll explore the Sensor Arcade infrastructure in some future lessons. The potential of using your iPad and its myriad of sensors is so exciting, and this is a great playground to test them all out!

Now we can see practical applications for all this code we’ve been learning about.

And we’ll certainly come back to these concepts and tools in the very near future.

Today’s session

For today, though, we’re going to explore one of my absolute favorite playgrounds: Cipher!

It’s a little bit about cryptography and coded messages and a tiny bit about code. But the reason why it’s my favorite playground is because it’s structured around a story.

We’ll experience the story and learn a little about crypto.

I can’t wait to get started on it with you. See you at 1pm!

Coding at Home: July 14th, Sensor Arcade, Gem Hunter

Join us today as we finish out Sensor Arcade at 1pm, Irish time!

Bumper Bash

We covered a lot of ground yesterday. In Bumper Bash, we learned about the collision handler, which lets us know which two sprites just collided with each other. This is a huge addition to our coding toolbox!

Now if we’re writing a game we can let the SpriteKit framework do the work of figuring out when two objects have collided.

Now, my high score wasn’t amazing for this one. Have you managed to beat it?

We’ll look at a few ways to cheat the system today — we’re coders, after all, we can write our own rules!

We’ll also explore the applyForce method on our sprites and see what that does.

Gem Hunter

We also moved on to Gem Hunter yesterday. This playground page combines all the inputs we’ve learned about: touch, light, sound, and collisions. We’re going to write a game that will use a few different ways of manipulating our player to get as many gems as possible.

My high score for this game, our first pass, also wasn’t brilliant, so please tell me you were able to beat me!

We’ll spend a little time rigging up some easy win scenarios today. Then we’ll think about what might make the game even more playable.

What behavior will our player have in reaction to light updates? Will we add some labels to see values from our events in real-time?

Come code with us today at 1pm, Irish time!

Coding at Home: July 13th, Bumper Bash

Join us today at 1pm, Irish time, for some more coding!

NB. We’re back at our usual time of 1pm, Irish time!

Recap: Sound Poppers

I hope you got to spend a bit of extra time with Sound Poppers and controlling those poppers to take out the balloons (and not the bombs!).

Did anyone beat my time?

Today’s session

Today we’ll continue exploring Sensor Arcade.

Remember when we made our own game/app a while ago?

We did some rough math to figure out if two objects collided in our scene. This let us make it look like a real game to our players.

This playground lesson uses a technology called SpriteKit. It sounds like a soda-making toolbox, but it’s Apple’s framework for building 2-dimensional games.

Using this framework, we can detect collisions between sprites, which are elements in our scene.

We’ll handle these collisions and call methods on our sprites to make them respond in suitably realistic ways.

Can you think of other places you might want to use this type of collision detection and physics (like applyImpulse, which we’ve already used)?

Join us today at 1pm and we’ll build some cool stuff!

Coding at Home: July 10th, Sensor Arcade, Sound Poppers

Join us today at 2pm today, Irish time, for some more coding with sensors!

NOTE the DIFFERENT time of 2pm! We’re just trying to keep you on your toes and really pushing for you to subscribe to our YouTube channel.

Yesterday’s lessons

Yesterday I hope you took some time to play around with different algorithms to see which one might result in the most fun for your game.

Remember, algorithms were simply a set of instructions and parameters we organized to solve a particular problem. There are many different ways to write code, some of which yield similar results. But now we can explore how well an algorithm performs by how well we do in the game!

In our default algorithm, provided by the playground, I got a high score of 63.2 meters and 4 donuts… not a great score, but not too bad.

Can you do better? Did you do better?

Today’s session

Today we move from the camera to the microphone!

We’re going to revisit pitch and tones today and use their numerical values to try and move things around the screen.

Come join us at 2pm, Irish time and we’ll make a bit of noise and have some fun!
