macshome / StoryboardExtensionsBeta4Fix.swift
Created Jul 29, 2014
NSTabView and NSSplitView are busted in beta 4 of Xcode 6 when using OS X Storyboards. If you are using Swift you can drop this file into your project to get them working until there is a fix.
View StoryboardExtensionsBeta4Fix.swift
// StoryboardExtensionsBeta4Fix.swift
// A workaround so that you can use SplitView
// and TabView items in OS X Storyboards on
// 10.10. Just drop this in your Swift project.
// Hopefully the need for this goes away in soon
// as it used to work.
macshome / SKPhyscisBody speed limiter
Created Jan 9, 2014
In my asteroids-style game I was looking for a way to limit the speed of the ship so that it didn't get too fast or outrun the missiles it fires. I call this with the update: method on the scene and it just checks the dx and dy values to make sure they are all inside the speed I want to set. In real code I would use a static or value loaded from…
View SKPhyscisBody speed limiter
// Speed limiter
- (void)shipSpeedLimit {
// Check the x velocity
if (self.ship.physicsBody.velocity.dx > 500) {
self.ship.physicsBody.velocity = CGVectorMake(500, self.ship.physicsBody.velocity.dy);
} else if (self.ship.physicsBody.velocity.dx < -500) {
self.ship.physicsBody.velocity = CGVectorMake(-500, self.ship.physicsBody.velocity.dy);
