私は、プレーヤーが障害物を避けてポイントを集めると思われるゲームを作っています。 1つのわずかな問題。 プレイヤーがポイント（別のSKSpriteNode）に衝突すると、プレーヤーは少しバウンスします。私は衝突の影響を受けずに "通過"したいと思っています。プレーヤーが他のSKSpriteNodesと衝突したときに「バウンス」を取り除く
これは、プレイヤーのクラスです：
import SpriteKit
struct ColliderType {
static let Player: UInt32 = 1
static let Swan: UInt32 = 2
static let Branch: UInt32 = 3
static let Score: UInt32 = 4
static let Wall1: UInt32 = 5
static let Wall2: UInt32 = 6
}
class Player: SKSpriteNode {
func initialize() {
self.name = "Player"
self.zPosition = 4
self.setScale(0.3)
self.anchorPoint = CGPoint(x: 0.5, y: 0.5)
self.physicsBody = SKPhysicsBody(circleOfRadius: self.size.height/
2 - 5)
self.physicsBody?.affectedByGravity = false
self.physicsBody?.restitution = 0
self.physicsBody?.categoryBitMask = ColliderType.Player
self.physicsBody?.collisionBitMask = ColliderType.Swan |
ColliderType.Branch | ColliderType.Wall1 | ColliderType.Wall2
self.physicsBody?.contactTestBitMask = ColliderType.Swan |
ColliderType.Score | ColliderType.Branch | ColliderType.Wall1 |
ColliderType.Wall2
}
}

はい、まさに私が欲しいものです。唯一の問題は、プレイヤーのcollisionBitMaskに "コイン"がなくても、contactBitMaskにしかないことです。私はまた、プレイヤーとコインの両方で ".physicsbody.collisionBitMask = 0"を入れて試してみました。しかし、まだそれはまだ迷惑ではないが、私はまだ小さな衝突を得る。 – Flinigan
