SpriteKit Rotating Triangle

Sample applications showing how to use SpriteKit on watchOS

• Objective-C
• RubyMotion

Requirements

• show a triangle on the screen using a PNG
• rotate the triangle
• tap on the screen to start/stop the rotation

How to run

Objective-C

• Open the project with XCode and press cmd+r

open objective-c/SKWatch.xcodeproj

RubyMotion

• Pair a Apple Watch Series 2 - 42mm to a simulator

• Enter the project directory

cd rm/skwatch

• Install main app (iOS) dependencies

bundle

• Enter the watch app (watchOS) directory

cd sk_watch_game

• Install the watch app dependencies

bundle

• Go back to the main app directory

cd ..

Run the main app (iOS)

[bundle exec] rake

May need to specify the iOS device id/name.

[bundle exec] rake device_name='iPhone 8'

Run the watch app (watchOS)

[bundle exec] rake watch

May need to specify the iOS device id/name that contains the previously paired
Series 2 watch.

[bundle exec] rake watch device_name='iPhone 8'

Notes

• The Objective-C version was created from the iOS SpriteKit template. In the same project, the watchOS SpriteKit template was added as a new target.
• The Objective-C version contains a shared TriangleNode class used by the iOS and watchOS apps
• The RubyMotion version contains a shared TriangleNode class used by the iOS and watchOS apps as well
• The RubyMotion version contains a shared TriangleRotationScene(rm/skwatch/shared/scenes/triangle_rotation_scene.rb) with the base code for adding the triangle PNG node and SKAction. A toggleRotateAction method also toggles the rotation SKAction of the TriangleNode.
• The RubyMotion version iOS app contains a GameController without the use of storyboards. A GameController instance is created and assigned as the rootViewController in the app delegate.
• The Objective-C and RubyMotion versions contain the same SpriteKit game scenes for both the iOS app and the watchOS app.
