STSpriteKit

SpriteKit helpers and additions.

Parallax

The STParallaxNode is a node that create parallax effect in a highly customizable way.

  • It handle both horizontal and vertical directions (but only one at a time).
  • You can add as many layers as you want on the parallax node.
  • You can control the speed of the parallax node over time.
  • Each layer has its own speed factor.
  • A layer can display one child. That child will be copied as soon as necessary, and may even be flipped one time in two.
  • A layer can display several childs. The pick up policy can be circular (in the array order) or random.
  • A layer can position its child with different values, including random one from a range.
  • The distance between each child of a layer is configurable with a random value from a range.

Controls

The two subclasses: STControlNode and STControlSprite allow to add some control methods on your nodes.

STControlNode

Those methods allow to be warn when a touchUp event is recognised:

- (void)setTouchUpTarget:(id)target action:(SEL)action;
- (void)setTouchUpBlock:(dispatch_block_t)touchUpBlock;

Those methods allow to be warn when a touchDown event is recognised:

- (void)setTouchDownTarget:(id)target action:(SEL)action;
- (void)setTouchDownBlock:(dispatch_block_t)touchDownBlock;

STControlSprite

Those methods allow to be warn when a touchUpInside event is recognised:

- (void)setTouchUpInsideTarget:(id)target action:(SEL)action;
- (void)setTouchUpInsideBlock:(dispatch_block_t)touchUpInsideBlock;

Those methods allow to be warn when a touchUpOutside event is recognised:

- (void)setTouchUpOutsideTarget:(id)target action:(SEL)action;
- (void)setTouchUpOutsideBlock:(dispatch_block_t)touchUpOutsideBlock;

Those methods allow to be warn when a touchDown event is recognised:

- (void)setTouchDownTarget:(id)target action:(SEL)action;
- (void)setTouchDownBlock:(dispatch_block_t)touchDownBlock;

Emitter

Those methods allow to easyly unarchive emitter resources:

+ (SKEmitterNode*)emitterWithResourceNamed:(NSString*)resourceName;
+ (SKEmitterNode*)emitterWithResourceNamed:(NSString*)resourceName inBundle:(NSBundle*)bundle;

Actions

This category add some convenient methods to run actions:

- (void)runActionsSequence:(NSArray*)actions;
- (void)runActionsSequenceForever:(NSArray*)actions;
- (void)runActionsGroup:(NSArray*)actions;
- (void)runActionsGroupForever:(NSArray*)actions;
- (void)runAction:(SKAction*)action afterDelay:(NSTimeInterval)delay;

SKScene

Propose an alternative algorithm for the SKScene's nodeAtPoint: method in order to deliver the touch to the pointed node considering its userInteractionEnabled value. In other words: if a node's userInteractionEnabled value is NO, the touch will be forwarded to the node below.

Utils

Add some function to easyly manipulate CGPoint and CGSize.

Usage

To include this component in your project, I recommend you to use Cocoapods:

  • Add pod "STSpriteKit" to your Podfile.
