Problems contact between two SpriteNodes - swift

Question

I have a problem with my func contact because the second contact don't work (contact with Bonus and Vaisseau) but the two others contact don't work.
So this is my code :
The function :
func didBeginContact(contact: SKPhysicsContact) {
let PremierBody : SKPhysicsBody = contact.bodyA
let SecondBody : SKPhysicsBody = contact.bodyB
if ((PremierBody.categoryBitMask == PhysicsCategories.Meteorites) && (SecondBody.categoryBitMask == PhysicsCategories.Meteorites)) {
contactEntreMeteorites(PremierBody.node as! SKSpriteNode, Meteorites2: SecondBody.node as! SKSpriteNode)
}
else if ((PremierBody.categoryBitMask == PhysicsCategories.Bonus) && (SecondBody.categoryBitMask == PhysicsCategories.Vaisseau) ||
(PremierBody.categoryBitMask == PhysicsCategories.Vaisseau) && (SecondBody.categoryBitMask == PhysicsCategories.Bonus)){
gameOver(PremierBody.node as! SKSpriteNode, Vaisseau: SecondBody.node as! SKSpriteNode)
print("CONTACT")
}
else if ((PremierBody.categoryBitMask == PhysicsCategories.Meteorites) && (SecondBody.categoryBitMask == PhysicsCategories.Vaisseau) ||
(PremierBody.categoryBitMask == PhysicsCategories.Vaisseau) && (SecondBody.categoryBitMask == PhysicsCategories.Meteorites)){
gameOver(PremierBody.node as! SKSpriteNode, Vaisseau: SecondBody.node as! SKSpriteNode)
print("Couco")
}
}
And this is my Physics categories :
struct PhysicsCategories {
static let Meteorites : UInt32 = 1
static let Bonus : UInt32 = 2
static let Vaisseau : UInt32 = 5
}
This in my func DidMoveToView :
Vaisseau = SKSpriteNode(texture: Vaisseau1)
Vaisseau.position = CGPointMake(self.frame.size.width / 2, self.frame.size.height / 2)
Vaisseau.physicsBody = SKPhysicsBody(rectangleOfSize: Vaisseau.size)
Vaisseau.physicsBody?.affectedByGravity = false
Vaisseau.physicsBody?.categoryBitMask = PhysicsCategories.Vaisseau
Vaisseau.physicsBody?.contactTestBitMask = PhysicsCategories.Bonus
Vaisseau.physicsBody?.contactTestBitMask = PhysicsCategories.Meteorites
Vaisseau.physicsBody?.dynamic = false
Vaisseau.setScale(0.08)
self.addChild(Vaisseau)
And i create my SpriteNode Bonus in this function :
func ApparitionBonus() {
let BonusSprite = SKSpriteNode(imageNamed: "Bonus.png")
var BonusApparitionX = UInt32(self.frame.size.width)
var BonusApparitionY = UInt32(self.frame.size.height)
BonusApparitionX = arc4random() % BonusApparitionX
BonusApparitionY = arc4random() % BonusApparitionY
BonusSprite.position = CGPointMake(CGFloat(BonusApparitionX),CGFloat(BonusApparitionY))
BonusSprite.setScale(0.8)
BonusSprite.physicsBody = SKPhysicsBody(circleOfRadius: 20)
BonusSprite.physicsBody?.affectedByGravity = false
BonusSprite.physicsBody?.categoryBitMask = PhysicsCategories.Bonus
BonusSprite.physicsBody?.contactTestBitMask = PhysicsCategories.Vaisseau
BonusSprite.physicsBody?.dynamic = false
self.addChild(BonusSprite)
let RotationBonus = SKAction.rotateByAngle(CGFloat(M_PI), duration: 3)
let wait = SKAction.waitForDuration(3)
let actionFini = SKAction.removeFromParent()
BonusSprite.runAction(SKAction.sequence([RotationBonus, wait, actionFini]))
BonusSprite.runAction(SKAction.repeatActionForever(RotationBonus))
}

Answer 1

In your didMoveToView, when you call:
Vaisseau.physicsBody?.contactTestBitMask = PhysicsCategories.Bonus
Vaisseau.physicsBody?.contactTestBitMask = PhysicsCategories.Meteorites
You set the contactTestBitMask to one category, and then another. You need to bitwise or them together. Something like:
Vaisseau.physicsBody?.contactTestBitMask = PhysicsCategories.Bonus | PhysicsCategories.Meteorites
This will combine the two bit masks, which will allow it to contact both the Bonus and Meteorites.
If you don't want your sprites to collide, set the collisionBitMask to 0x0 (or however you want to represent 0):
Vaisseau.physicsBody?.collisionBitMask = 0x0
