I have more problems within my app. My errors is as the title says:
Error1: 'CGFloat' is not Convertible to 'Float'
Code for the 1st and 2nd error:
self.setPositionRelativeBot(pipeBot, x: xx, y: offset)
self.setPositionRelativeTop(pipeTop, x: xx, y: offset + space)
Here is the whole func:
func spawnPipeRow(offs: Float)
{
let offset = offs - space / 2
let pipeBot = mainPipe.copy() as Pipe
let pipeTop = mainPipe.copy() as Pipe
pipeBot.texture = SKTexture(imageNamed: "BotPipe")
pipeTop.texture = SKTexture(imageNamed: "TopPipe")
pipeBot.texture!.filteringMode = SKTextureFilteringMode.Nearest
pipeTop.texture!.filteringMode = SKTextureFilteringMode.Nearest
pipeBot.isBottom = true
let xx = self.view!.bounds.size.width
self.setPositionRelativeBot(pipeBot, x: xx, y: offset)
self.setPositionRelativeTop(pipeTop, x: xx, y: offset + space)
pipeBot.physicsBody = SKPhysicsBody(rectangleOfSize: pipeBot.size)
pipeTop.physicsBody = SKPhysicsBody(rectangleOfSize: pipeTop.size)
pipeBot.physicsBody!.dynamic = false
pipeTop.physicsBody!.dynamic = false
pipeBot.physicsBody!.contactTestBitMask = birdCategory
pipeTop.physicsBody!.contactTestBitMask = birdCategory
pipeBot.physicsBody!.collisionBitMask = birdCategory
pipeTop.physicsBody!.collisionBitMask = birdCategory
pipes.append(pipeBot)
pipes.append(pipeTop)
self.addChild(pipeBot)
self.addChild(pipeTop)
}
Error1: 'Float' is not identical to 'UInt8'
Code for the 1st error:
vel -= 85 - (self.view!.bounds.size.height - bird.position.y)
Error2: 'SKPhysicsBody?' does not have a member named 'velocity'
Code for the 2nd error:
bird.physicsBody.velocity = CGVectorMake(0, vel)
Here is the whole func:
override func touchesBegan(touches: NSSet, withEvent event: UIEvent)
{
if (!bird.physicsBody!.dynamic)
{
//First touch
self.spawnPipeRow(0)
bird.physicsBody!.dynamic = true
bird.physicsBody!.velocity = CGVectorMake(0, 175)
scoreLabel.hidden = false
isMoving = true
} else if (isMoving)
{
var vel: Float = 200
if (self.view!.bounds.size.height - bird.position.y < 85)
{
vel -= 85 - (self.view!.bounds.size.height - bird.position.y)
}
bird.physicsBody.velocity = CGVectorMake(0, vel)
} else
{
overlay.removeFromParent()
for pi in pipes
{
pi.removeFromParent()
}
pipes.removeAll(keepCapacity: false)
score = 0
bird.physicsBody!.dynamic = false
bird.position = CGPoint(x: 150, y: view!.bounds.size.height / 2 - 10)
scoreLabel.hidden = true
isGroundMoving = true
}
}
Error1: 'CGFloat' is not identical to 'UInt8'
Code for the 1st and 2nd error (Same error both lines):
ground1.position.x -= movingSpeed
ground2.position.x -= movingSpeed
Error2: Cannot invoke '-=' with an argument list of type '(@lvalue CGFloat, $T9)'
Code for the 3rd and 4th error (Same error both lines):
background1.position.x -= movingSpeed / 3
background2.position.x -= movingSpeed / 3
Error3: 'CGFloat' is not identical to 'UInt8'
pipe.position.x -= movingSpeed
Here is the whole func:
override func update(currentTime: CFTimeInterval)
{
if (isGroundMoving)
{
ground1.position.x -= movingSpeed
ground2.position.x -= movingSpeed
if (ground1.position.x <= -self.view!.bounds.size.width / 2)
{
ground1.position.x = self.view!.bounds.size.width * 1.5 - 2
}
if (ground2.position.x <= -self.view!.bounds.size.width / 2)
{
ground2.position.x = self.view!.bounds.size.width * 1.5 - 2
}
background1.position.x -= movingSpeed / 3
background2.position.x -= movingSpeed / 3
if (background1.position.x <= -self.view!.bounds.size.width / 2)
{
background1.position.x = self.view!.bounds.size.width * 1.5 - 2
}
if (background2.position.x <= -self.view!.bounds.size.width / 2)
{
background2.position.x = self.view!.bounds.size.width * 1.5 - 2
}
if (isMoving)
{
for (var i = 0; i < pipes.count; i++)
{
let pipe = pipes[i]
if (pipe.position.x + (pipe.size.width / 2) < 0)
{
pipe.removeFromParent()
continue
}
if (pipe.position.x + (pipe.size.width / 2) < self.view!.bounds.size.width / 2 && pipe.isBottom && !pipe.pointAdded)
{
score++
pipe.pointAdded = true
}
pipe.position.x -= movingSpeed
if (i == pipes.count - 1)
{
if (pipe.position.x < self.view!.bounds.width - pipe.size.width * 2.0)
{
self.spawnPipeRow(self.randomOffset())
}
}
}
scoreLabel.text = "Score: \(score)"
}
}
}
I hope some of you guys can figure this out for me because I can't :)
Error 1: Use CGFloat
instead of Float
. For example:
var vel: CGFloat = 200
Error 2: physicsBody is an optional (can be nil), so use ?.
operator to conditionally unwrap it before referencing its velocity
:
bird.physicsBody?.velocity = CGVectorMake(0, vel)
All of your errors seem to be caused by one of these two issues. For example, spawnPipeRow
's argument is again offs: Float
instead of CGFloat
. And I suspect the same is true of the values that you did not declare in the snippets you provided, such as space
or movingSpeed
.
To understand what CGFloat
is, Command-click on it – this will take you to CoreGraphics
API where you can read that CGFloat
is a "native type ... which is Float on 32-bit architectures and Double on 64-bit architectures."
Also, I would tend to use ?
rather than !
when modifying physicsBody
as the latter will crash if the physicsBody
is nil.
