http://i.imgur.com/xkWTk9i.png I already got this rectangle to go from top to bottom. The problem I have is that I want it to repeat every 2 seconds so another rectangle is following it. I want my code to spawn the rectangles every 2 seconds and have it repeat like in flappy bird does with the green pipes. Thank you. (I got this to work before but I deleted my project by mistake and cant figure out how I did it in the first place.) Im in Swift using Spritekit.
.
class GameScene: SKScene {
let sprite = SKSpriteNode(imageNamed: "Rectangle 12")
override func didMoveToView(view: SKView) {
self.addChild(sprite)
//run doAction function
doAction()
}
//movement of rectangle
func createRectangle() {
let moveToBottom = SKAction.moveByX(0, y: 0 - self.frame.size.width , duration:
NSTimeInterval (3.0))
let removeTheNode = SKAction.removeFromParent()
let moveAndRemovePipes = SKAction.sequence([moveToBottom, removeTheNode])
let repeatAction = SKAction.repeatActionForever(moveAndRemovePipes)
sprite.xScale = 1
sprite.yScale = 1
sprite.position = CGPoint(x:0,y:0)
sprite.runAction(repeatAction)
}
//spawn multiple rectangles after 3 or 4 seconds
func doAction() {
let generateRectangles = SKAction.sequence([
SKAction.runBlock(self.createRectangle),
SKAction.waitForDuration(NSTimeInterval(3.0))])
let endlessAction = SKAction.repeatActionForever(generateRectangles)
runAction(endlessAction)
}
}
