Questions tagged [skemitternode]

A SKEmitterNode object is a node that automatically creates and renders small particle sprites. Particle sprites are privately owned by Sprite Kit—your game cannot access the generated sprites. For example, this means you cannot add physics shapes to particles. Emitter nodes are often used to create smoke, fire, sparks, and other particle effects. Available in iOS 7.0 and later.

Objective C - SKEmitterNode position range

Question is how to define a non-rectangular shape for emitter node position range? By position range I mean this: emitter.particlePositionRange = CGVectorMake(50,75); Is there some workaround to make this area triangular instead of rectangular?

Detecting when SKEmitterNode particle makes contact with another SKNode

Does anyone know how I can detect when an SKEmitterNode particle makes contact with a SKNode in the SKScene? I want to apply a little force to the SKNode when a particle makes contact with it for a 2D game I'm creating.
