我试图让玩家与SKNode发生碰撞。这样做时,我希望粒子显示一个SKNode只是was(player)的图片并显示效果。当我尝试创建它时,发射器未显示播放器所在的位置。我怎样才能解决这个问题?

    func didBegin(_ contact: SKPhysicsContact) {

        let bodyA = contact.bodyA
        let bodyB = contact.bodyB




 if bodyA.categoryBitMask == 1 && bodyB.categoryBitMask == 2 || bodyB.categoryBitMask == 1 && bodyA.categoryBitMask == 2  {
        let player = SKNode(fileNamed: "player")
        let explostion = SKEmitterNode(fileNamed: "explosion.sks")
        let addExplosion = SKAction.run {
            player?.addChild(explostion!)

        }
        let seq = SKAction.sequence([addExplosion])

        self.addChild(explostion!)
        self.run(seq)

        }

    }

最佳答案

可能是物理实体之一属于玩家的节点吗?因此,您可以从身体访问它。例如,让玩家的身体-是bodyA:

  if bodyA.categoryBitMask == 1 && bodyB.categoryBitMask == 2 || bodyB.categoryBitMask == 1 && bodyA.categoryBitMask == 2  {
        let player = bodyA.node
        let explostion = SKEmitterNode(fileNamed: "explosion.sks")
        player.addChild(explostion!)
        }
    }
