Contact of Nodes with Subclass - ios

Question

im creating a class to add my Meteors to the scene:
import SpriteKit
class Meteor: SKShapeNode {
var meteorNode : SKShapeNode?
var size : CGSize!
//Acoes
var acaoApagar = SKAction.removeFromParent()
var acaoAndar : SKAction!
//Numero Randomico
var numRandom : Int = 0
var textoStringMeteor : String!
//Colisoes
let CollisionShoot : UInt32 = 0x1 << 0
let CollisionHouse : UInt32 = 0x1 << 1
let CollisionMeteor : UInt32 = 0x1 << 2
init(size : CGSize, pontoMeteor: CGPoint, textoMeteor: String)
{
super.init()
//super.init(ellipseOfSize: <#CGSize#>)
self.size = size
self.textoStringMeteor = textoMeteor
self.acaoAndar = SKAction.moveTo(pontoMeteor, duration: 10)
criarMeteoro()
setarTexto(self.textoStringMeteor)
}
func setarTexto(numeroLabel : String) {
let numNode = SKLabelNode(fontNamed:"Chalkduster")
numNode.text = numeroLabel;
numNode.fontSize = 20;
numNode.position = CGPoint(x: 0, y: -10);
numNode.name = "textoNode"
meteorNode?.addChild(numNode)
}
func criarMeteoro() {
var randomX = CGFloat(Int(arc4random()) % Int(size.width))
//Meteor Node
meteorNode = SKShapeNode(circleOfRadius: CGFloat(20))
meteorNode!.physicsBody = SKPhysicsBody(circleOfRadius: 20)
meteorNode!.physicsBody!.dynamic = true
meteorNode!.fillColor = UIColor.blueColor()
meteorNode!.physicsBody!.categoryBitMask = CollisionMeteor
meteorNode!.physicsBody!.contactTestBitMask = CollisionShoot | CollisionHouse
meteorNode!.position = CGPoint(x: randomX, y: size.height + 900)
meteorNode!.name = "meteorNode"
self.addChild(meteorNode!)
meteorNode!.runAction(SKAction.sequence([acaoAndar, acaoApagar]))
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
Here im calling the class Meteor and passing all parameters:
var meteor = Meteor(size: CGSize(width: size.width, height: size.height), pontoMeteor: ponto, textoMeteor: "30")
foreground.addChild(meteor)
And for the last i have my contact to see if there was contact between the nodes:
func didBeginContact(contact: SKPhysicsContact) {
var bodyA = contact.bodyA!.node!
var bodyB = contact.bodyB!.node!
if bodyA.name == "tiroCanhao" && bodyB.name == "meteorNode"
{
bodyB.removeAllActions()
bodyB.removeFromParent()
bodyA.removeFromParent()
self.pointsPlayer++
self.qtdtiros += 2
}
else if bodyA.name == "meteorNode" && bodyB.name == "tiroCanhao"
{
bodyA.removeAllActions()
bodyA.removeFromParent()
bodyB.removeFromParent()
self.pointsPlayer++
self.qtdtiros += 2
}
}
Now my problem is the follow:
After the contact i want to call the setarTexto method on the Meteor class of the object and change the text but that isnt working. I get this error:
Could not cast value of type 'SKShapeNode' (0x10bb5ea88) to
'MathDefense.Meteor' (0x10af6b7b0).
What im doing is this (on the if statement on contact):
let text = bodyB as! Meteor
text.setarTexto("20")
I even tried
text.textoStringMeteor = "20"
But none of those worked. I already done some research but didn't find any person with my problem or trying to do something similar.
Any solution?
Thanks.

Answer 1

I found the solution, to fix my error i made the following:
Remove the SKShapenode since the class is already a SKShapenode (that was the error).
Then when creating my node i made everthing with self instead of putting in the Meteornode. That fixed all.
Example:
Right: self.position = CGPoint(x: randomX, y: size.height + 900)
Wrong: meteorNode!.position = CGPoint(x: randomX, y: size.height + 900)
To pass texture if you are using a SKSpritenode just put it on your superinit.
