SceneKit – How to make self defined particle effect in Xcode 13?-CodePudding

I am trying to mock an explosion particle effect in xcode 13 as below style

because there is no .scnp file I can use in xcode 13, I tried to use below code to complete,

let particleSystem = SCNParticleSystem()
particleSystem.birthRate = 800
particleSystem.loops = false
particleSystem.blendMode = .alpha         
particleSystem.particleSize = 0.030
particleSystem.emitterShape = SCNSphere(radius: 0.9)
particleSystem.particleColor = .yellow
particleSystem.particleLifeSpan = 0.5
particleSystem.particleImage = "art.scnassets/spark.png"
particleSystem.particleColorVariation = SCNVector4(0.5, 0.5, 0.5, 0)

But the result is not expected.

Can anyone help to give any instruction how to do that?

CodePudding user response：

To setup particles in UI, choose SceneKit's .scn file in Navigator panel and then add a Particle System object from Xcode 13 library pressing button (instead of a deprecated .scnp file):
