I am making a game that requires you to dodge falling objects. I have tried to make it it so that when the falling object hits the player certain code runs. But it is not working please show me what is wrong with my code.
import SpriteKit
struct physicsCatagory {
static let person : UInt32 = 0x1 << 1
static let Ice : UInt32 = 0x1 << 2
}
class GameScene: SKScene, SKPhysicsContactDelegate {
var person = SKSpriteNode(imageNamed: "Person")
override func didMoveToView(view: SKView) {
physicsWorld.contactDelegate = self
person.position = CGPointMake(self.size.width/2, self.size.height/12)
person.setScale(0.4)
person.physicsBody = SKPhysicsBody(rectangleOfSize: person.size)
person.physicsBody?.affectedByGravity = false
person.physicsBody?.categoryBitMask = physicsCatagory.person
person.physicsBody?.contactTestBitMask = physicsCatagory.Ice
person.physicsBody?.dynamic = false
var IceTimer = NSTimer.scheduledTimerWithTimeInterval(0.5, target: self, selector: Selector("spawnFirstIce"), userInfo: nil, repeats: true)
self.addChild(person)
func didBeginContact(contact: SKPhysicsContact) {
let firstBody = contact.bodyA
let secondBody = contact.bodyB
if firstBody.categoryBitMask == physicsCatagory.person && secondBody.categoryBitMask == physicsCatagory.Ice || firstBody.categoryBitMask == physicsCatagory.Ice && secondBody.categoryBitMask == physicsCatagory.person{
NSLog ("Test Test") }
}
}
func spawnFirstIce(){
let Ice = SKSpriteNode(imageNamed: "FirstIce")
Ice.setScale(0.5)
Ice.physicsBody = SKPhysicsBody(rectangleOfSize: Ice.size)
Ice.physicsBody?.categoryBitMask = physicsCatagory.Ice
Ice.physicsBody?.contactTestBitMask = physicsCatagory.person
Ice.physicsBody?.affectedByGravity = false
Ice.physicsBody?.dynamic = true
let MinValue = self.size.width / 8
let MaxValue = self.size.width - 20
let SpawnPoint = UInt32(MaxValue - MinValue)
Ice.position = CGPoint(x: CGFloat(arc4random_uniform(SpawnPoint)), y: self.size.height)
self.addChild(Ice)
let action = SKAction.moveToY(-85, duration: 3.0)
let actionDone = SKAction.removeFromParent()
Ice.runAction(SKAction.sequence([action,actionDone]))
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
for touch in touches {
let location = touch.locationInNode(self)
person.position.x = location.x
}
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
for touch in touches {
let location = touch.locationInNode(self)
person.position.x = location.x
}
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
}
}
