自从我从Xcode 6 Beta 6升级到Xcode 6.0.1后,我遇到了一个问题。
使用Xcode 6.0.1,我有62个错误,但没有测试版。
示例:
balloonro.physicsBody = SKPhysicsBody (circleOfRadius: balloonro.size.width/2)
balloonro.physicsBody.dynamic = true
balloonro.physicsBody.categoryBitMask = balloonCategory | pinkCategory
balloonro.physicsBody.contactTestBitMask = flechetteCategory
balloonro.physicsBody.collisionBitMask = balloonCategory
balloonro.physicsBody.mass = 1
balloonro.physicsBody.restitution = 1
balloonro.physicsBody.allowsRotation = true
在所有行上,Xcode 6.0.1说:
“SKPhysicsBody?没有名为'restitution / mass / dynamic / etc'的成员
我该怎么做才能解决这个问题?
答案 0 :(得分:1)
SKPhysicsBody?
是可选值。你必须打开它或使用可选的链接。例如,
balloonro.physicsBody?.dynamic = true
