Space Invaders is an arcade video game developed by Tomohiro Nishikado and released in 1978. It was originally manufactured and sold by Taito in Japan, and was later licensed for production in the United States by the Midway division of Bally. Space Invaders is one of the. Space invaders ship collection of 25 free cliparts and images with a transparent background. Download and use for design of your work.
Update Note: Check out the using iOS 8 and Swift!Space Invaders is one of the most important video games ever developed. Created by Tomohiro Nishikado and released in 1978 by Taito Corporation, it earned billions of dollars in revenue. It became a cultural icon, inspiring legions of non-geeks to take up video games as a hobby.Space Invaders used to be played in big game cabinets in video arcades, chewing up our allowances one quarter at a time. When the Atari 2600 home video game console went to market, Space Invaders was the “killer app” that drove sales of Atari hardware.In this tutorial, you’ll build an iOS version of Space Invaders using Sprite Kit, the 2D game framework newly introduced in iOS 7.This tutorial assumes you are familiar with the basics of Sprite Kit. If you are completely new to Sprite Kit, you should go through our first.Also, you will need an iPhone or iPod Touch running iOS 7 and an Apple developer account in order to get the most out of this tutorial. That is because you will be moving the ship in this game using the accelerometer, which is not present on the iOS simulator. If you don’t have an iOS 7 device or developer account, you can still complete the tutorial — you just won’t be able to move your ship.Without further ado, let’s get ready to blast some aliens!
Note: If you've been testing your code on simulator up till now, this would be the time to switch to your device. You won't be able to test the tilt code unless you are running the game on an actual device.Build and run your game and try tilting your device left or right; your ship should respond to the accelerometer, as follows:What do you see? Your ship will fly off the side of the screen, lost in the deep, dark reaches of space. If you tilt hard and long enough in the opposite direction, you might get your ship to come flying back the other way. But at present, the controls are way too flaky and sensitive.
You'll never kill any invaders like this!An easy and reliable way to prevent things from escaping the bounds of your screen during a physics simulation is to build what's called an edge loop around the boundary of your screen. An edge loop is a physics body that has no volume or mass but can still collide with your ship. Think of it as an infinitely-thin wall around your scene.Since your GameScene is a kind of SKNode, you can give it its own physics body to create the edge loop.Add the following code to createContent right before the self setupInvaders; line:self.physicsBody = SKPhysicsBody bodyWithEdgeLoopFromRect:self.frame;The new code adds the physics body to your scene.Build and run your game once more and try tilting your device to move your ship, as below:What do see? If you tilt your device far enough to one side, your ship will collide with the edge of the screen. It no longer flies off the edge of the screen. Problem solved!Depending on the ship's momentum,you may also see the ship bouncing off the edge of the screen, instead of just stopping there. This is an added bonus that comes for free from Sprite Kit's physics engine — it's a property called restitution.

Not only does it look cool, but it is what's known as an affordance since bouncing the ship back towards the center of the screen clearly communicates to the user that the edge of the screen is a boundary that cannot be crossed. Where to Go From Here?Here is the for the game up to this point.So far, you've created invaders, your ship, and a Heads Up Display (HUD) and drawn them on-screen. You've also coded logic to make the invaders move automatically and to make your ship move as you tilt your device.In, you'll add firing actions to your ship as well as the invaders, along with some collision detection so you'll know when you've hit the invaders — and vice versa! You'll also polish your game by adding both sound effects as well as realistic images to replace the colored rectangles that currently serve as placeholders for invaders and your ship.In the meantime, if you have any questions or comments, please feel free to join in the discussions below!
