This tutorial is amazing. I have been out of the App creation mode for about 7 years and so much has changed. Thank you for providing these tutorials!

Hi Paul, such a wonderful stream, enjoyed every bit of it. The way you explain the SpriteKit feature & the game was really great. Thank you...

Paul, thanks for this video. It was incredibly helpful.

I love this so much, your videos are to the point, educational, and easy to follow. Thanks a lot!

Thank you for amazing tutorial on Sprite Kit. It's really a good start for me on SpriteKit.

thanks for everything you teach! you are one of the best and brightest teachers I have ever had. I bought the book, it's amazing! Thank you very much.

Still watching. About half way through. This was a great tutorial! Information still relevant today!

Learned lots from this. Thank you!

For determining the ‘end of game condition’, do this. Define a var ballColorCount = [0, 0, 0, ..., 0, 0] where the # of elements in the array = # colors you have. When you initialize the random balls at the beginning, add 1 to the array index for that color ball (a good use of an enumeration with an Int raw value). As you make matches, subtract from the count for a particular color the # of balls in the set of “adjacent” balls, plus 1 for the original ball. Once no element of the array >= 3, the game is over; there’s no way to make a match-3 with any colored ball. The array is a histogram of the ball’s colors at any point in the game. This approach is a lot easier than trying to mathematically determining how many balls there must be to still have a match, taking into account that you might have 15 balls, but they’re all at the bottom of the screen, and no adjacent balls are the same color, even though you might still have - let’s say - 4 green ones, 3 red ones, 2 purple ones, 3 yellow ones and 3 blue ones. But they could make a match if you tilt the device and allow the balls (using the physics engine) to rearrange themselves.

This is one of the best fast intro & tutorial I ever seen (on any technology tbh). Nice paced, clear and on point! Amazing work!

(@1:30:00) “...Metal is hard.” LOL! Good one! 😆

Perfect Video

👍 I’ll keep watching I need to learn haha

Nice video. Paul can you make a video about creating cloth physics with metal framework?

Thanks for your videos!!! Please do more game tutorials in Spritekit or Scenekit :) It would be great to get a game setup tutorial that includes the use of inventory to hold items for use during game play.

Thanks so much Paul for a very entertaining and very informative and useful session.

Hi Paul, thanks for the great tutorial, but when I follow your tutorial, I only get a frame width of 1024 using an iPad Pro 12.9. I tried to change the settings at many location but I can never get more then 23 balls to fit horizontally (23*44). In your video, you do not have that issue and we can see that you have 31 horizontal balls which is 1364 which sounds more like it should be at 2x scale right? What am I doing wrong. I'm using Xcode 12.5 with iOS 14.5. Cheers!

I've made everything on your lesson but in method update "if let accelerometerData = motionManager?.accelerometerData", accelerometerData is always nil. Therefore it never let me implement the down code "physicsWorld.gravity = CGVector(dx: accelerometerData.acceleration.y * 50.0, dy: accelerometerData.acceleration.x * 50.0)". So, what's the hitch? Help me plz, stunning lesson!!!

What resource did you use to learn the basics and fundamentals of SpriteKit

Great👍

How were the colors of the balls generated?

Thanks Paul. Excellent presentation as usual. Minor Leak: Forgot to remove the omg nodes after they fadeout. let disappear = SKAction.group([ SKAction.scale(to: 2, duration: 0.25), SKAction.fadeOut(withDuration: 0.25), SKAction.removeFromParent() ]) Was able to finish the game with 9 nodes (6 remaining balls + background + score label + one unaccounted). Is there a way to debug SpriteKit to see the remaining nodes?

Given these two implementations of getMatches(), would it be better to make touchesEnded() call another func called ‘removeBallsOfMatchingColor()’ that takes a closure that takes a Ball and returns Void, then move the existing code in touchesEnded() into this new func, and have it pass in a func that takes a Ball and returns Void (which each implementation of getMatches() does). You can now implement both: call the first func, ‘getExactMatches()’, and the second one ‘getMatchesWithLeeway().’ And pass in one or the other to see what the difference in game play or performance is with each implementation. 🤠 Now you can add a new type of Ball; a ‘PebblyBall’ that has a rough, pebbly surface. In addition, the PebblyBalls have a unique property. Whereas a normal (smooth) Ball will match any other normal Ball of matching color when tapped, the PebblyBall will match any normal or pebbly ball of the same color, but only if you tap on it first. Now, you’ll have another method, ‘getMatchesWithPebblyBall()’, and touchedEnded will check if the touched ball is a Ball or PebblyBall, and call the ‘removeBallsOfMatchingColor()’ with this new method, and no changes need be made to ‘removeBallsOfMatchingColor()’ as it’s already flexible enough to use any closure that takes a ‘Ball’ (or subclass thereof), and returns Void. Ta-daa!

The zero patience police for harassment made me like your video as soon as I heard it

Idea for a video ... Rendering a 3d dice app. Show how to use physics and 3d rendering within a swiftUI interface

thanks this is very useful! Cant really find an answer anywhere in 2019.. are there any performance advantages in using SpirteKit over a modern engine (Unity/Godot)>

thx

Could you share links to your plugs? You mentioned a fun choose your own adventure for $40 but I’m having trouble finding in the video - found at 1:20:00 links to shaders and SpriteKit game

Who's METAL book was that you mentioned? ( 1:02: )

hugh grant hudson

So, would spritekit be considered a " real game changer"? Lol #nerdjoke
