我想实现类似periscope对他们的直播应用程序做的事情.具体而言,当用户触摸屏幕时发出无数浮心.这可以通过SpriteKit或Cocos2D轻松实现吗？任何人都可以给我一些灯光,或者至少是一个很好的起点.
谢谢
解决方法
这可以通过SKEmitterNode实现
import SpriteKit
let heartsFile = "heart-bubbles.sks"//particle file
class HeartBubblesScene : SKScene {
var emitter: SKEmitterNode?
func beginBubbling() {
emitter = SKEmitterNode(fileNamed: heartsFile)
let x = floor(size.width / 2.0)
let y = heartHeight
emitter!.position = CGPointMake(x,y)
emitter!.name = "heart-bubbles"
emitter!.targetNode = self
emitter?.numParticlesToEmit = 1
addChild(emitter!)
emitter?.resetSimulation()
}
}
class ViewController: UIViewController {
@IBOutlet weak var heartBubblesView: SKView!//Create a custom view inside view controller and set the class to SKView
let heartBubblesScene = HeartBubblesScene()
override func viewDidLoad() {
super.viewDidLoad()
heartBubblesView.presentScene(heartBubblesScene)
}
override func touchesBegan(touches: Set<UITouch>,withEvent event: UIEvent?) {
heartBubblesScene.beginBubbling()
}
}
