无法将CGPoint转换为预期的参数CGFloat

Question

这是显示错误的代码行

let moveEnemy = SKAction.moveTo(x: endPoint, duration: 1.5)

里的所有东西都在这里

let startPoint = CGPoint(x: randomXStart, y: self.size.height * 1.2)
let endPoint = CGPoint(x: radnomXEnd, y: -self.size.height * 0.2)

let enemy = SKSpriteNode(imageNamed: "enemy")
enemy.setScale(1)
enemy.position = startPoint
enemy.zPosition = 2
self.addChild(enemy)

let moveEnemy = SKAction.moveTo(x: endPoint, duration: 1.5)
let deleteEnemy = SKAction.removeFromParent()
let enemySequence = SKAction.sequence([moveEnemy, deleteEnemy])
enemy.runAction(enemySequence)

Answer 1

错误很明显：endPoint是CGPoint，moveTo(x:duration:)的第一个参数是CGFloat

使用点API

let moveEnemy = SKAction.move(to: endPoint, duration: 1.5)

或者得到点的x部分

let moveEnemy = SKAction.moveTo(x: endPoint.x, duration: 1.5)
