使用多个didBegin联系人- SpriteKit

import SpriteKit

class GameScene: SKScene, SKPhysicsContactDelegate {
    
    override func didMove(to view: SKView) {
        physicsWorld.contactDelegate = self
    }
    
    func didBegin(_ contact: SKPhysicsContact) {
        if contact.bodyA.categoryBitMask == PhysicsCategory.player && contact.bodyB.categoryBitMask == PhysicsCategory.enemy {
            // 处理玩家与敌人碰撞的逻辑
        }
    }
    
    func didBegin(_ contact: SKPhysicsContact) {
        if contact.bodyA.categoryBitMask == PhysicsCategory.player && contact.bodyB.categoryBitMask == PhysicsCategory.powerUp {
            // 处理玩家与道具碰撞的逻辑
        }
    }
    
    // 其他didBegin(contact:)方法...
    
}

struct PhysicsCategory {
    static let player: UInt32 = 0x1 << 0
    static let enemy: UInt32 = 0x1 << 1
    static let powerUp: UInt32 = 0x1 << 2
    // 其他物体类型...
}
