SpriteKit Introduction - iOS Game Development with Swift 3

I will show you how the structure of SpriteKit is, so you understand the framework.This will help you later at coding

In this video I will show you about the render order in SpriteKit. This will help you later at coding

In this video I will show how you position images in your game. This will help you later at coding

I will show you what die Superclass SKNode is. This will help you later at coding

In this second Section I will explain how the physics simulation in SpriteKit work, because this makes a game really awesome

We can only use physics simulation in our game when we at physics bodys to our nodes, that I show you here

Here we will create our startscene, so we have to press play to start the game

Here we will make a transition from our startscene to our gamescene

We add a background image to our game

Now we will add our spaceship to the game and animate it

How me make a endless background, this you see here in this video

In this video I show you how me can move our spaceship with the function touchesMoved

Now we will add randomly three different asteriod to our game and spawn them endless 

When we move our spaceship we shoot bullets, here we will make a function to shoot bullets if the user move our spaceship. We also use the class SKAction to move our bullets.

Here we will add endless enemys, I show you also that spritekit work in radient and not in degree if you want for example change the direction of a image. We give the enemy actions and for that we use the class SKAction which can only be use by nodes.

We have a enemy and now we want to animate it, so thats look better

I show you how we add music to our game, for this we use the Framework AVFoundation

In this video we add a function to break the music and start it again if the user press on a sound ON/OFF button

We add hearts image to our game, we need this later as live for our spaceship

We add in this video a physics body to our nodes so our nodes can be affected by physics

We give in this video our physics body numbers so we can decide later which physics body interact each other

We implement the protocol SKPhysicsContactDelegate and that protocol has two functions that we can call if two physics bodys get in contact

I show you what will happen if our physics body from spaceship and enemy get in contact for that we use the function didBegin() from the protocol SKPhysicsContactDelegate

We add a score label from the class SKLabelNode so we see how many enemys we destroyed

If our bullet hit the enemy our enemy exploded in a fireball 

We add a new file to our game and make a new class which inherit from the class SKScene and this class is our gameover scene if we lose our spaceship lives

We give our spaceship a shield, so now we have spaceship live and a shield before we are gameover

We greate a function to add live  for our shield and for this we use the class SKShapeNode

To get in physics simulation or interaction between physics bodys we have to add physics bodys to our nodes. In this video we give our shield a phyiscs body to get in interaction with our enemy

We use the function didBegin from the  protocol SKPhysicsContactDelegate to decide what will happen if the enemy hit our shield

If we lost our shield we are angry and shoot now 2 bullets at same time
