debreuil / RungeKuttaSpringImplementation.m

Created February 3, 2015 22:50

Pixate spring implementation

	// Evaluates one tick of a spring using the Runge-Kutta Algorithm.
	// This is generally a bit mathy, here is a reasonable intro for those interested:
	// http://gafferongames.com/game-physics/integration-basics/
	// (double)stepSize: the duration between steps. This should be around 1/60th of a second. Values too large will not work as the spring adjusts itself over time based on previous values, so if values are larger than 1/60th of a second this method should be called for each whole 1/60th of a second segment plus the remainder.

	// external variables
	// (double) _curT: How far along the spring the current value is, 0 being start and 1 being end. Because this is a spring that value will go beyond 1 and then back below 1 etc, as it 'springs'.
	// (double) _tVelocity: the current velocity of the spring.
	// (BOOL) _stopSpring: indicates the spring has settled to minimum amount and should be considered the last 'tick'

debreuil / nested_curried.swift

Last active August 29, 2015 14:02

	// What are nested and curried functions? How do you use them in Swift?
	// nesting/currying allows piping function calls together like fn(1)(2)(3)

	// multiple functions, requires fnA(1) + fnB(2) + fnC(3) syntax
	func daysToSeconds(days:Int)->Int {
	return days * 24 * 60 * 60
	}
	func hoursToSeconds(hours:Int)->Int {
	return hours * 60 * 60

debreuil / castingFromAnyObject.swift

Created June 12, 2014 03:22

	// How to you safely convert an AnyObject with a number value into a Double?

	let anyDouble:AnyObject = 6.41
	if let xx = anyDouble as? NSNumber {
	println( Double(xx)) // prints 6.41
	}
	// will throw an error if the conversion fails!
	let casted = Double(anyDouble as NSNumber) // 6.41

debreuil / tupleComparisons.swift

Created June 12, 2014 03:12

	// How do you compare tuples for equality?

	var tupleA = (1, "one")
	var tupleB = (1, "one")
	// tup == tup2 // error: tuples can not be compared with ==, can not be used as hash key etc
	// If you need to test for object equality, a tuple is not suitable
	tupleA.0 == tupleB.0 && tupleA.1 == tupleB.1 // but you can do this
	// you can also use element names
	var tupleC = (a:1, b:"one")
	tupleA.0 == tupleC.a && tupleA.1 == tupleC.b

debreuil / keysFromDictionary.swift

Created June 12, 2014 03:09

	// How do you get the keys from a dictionary?

	let array = [1,2,3]
	let dict = [1: "One", 2: "Two", 3: "Three"]
	// cast to get the keys in an array
	var keys = Array(dict.keys)
	keys == array // comapre arrays with ==
	var values = Array(dict.values) // the same works for values
