I have viewed questions with this same error but can't seem to relate it to my issue. I am running a thread as such:
我已经用同样的错误查看了问题,但似乎无法将其与我的问题联系起来。我正在运行一个线程:
let ballGen = BallGenerator()
run(SKAction.repeatForever(
SKAction.sequence([
SKAction.run(ballGen.addBall(size.width, size.height)),
SKAction.wait(forDuration: 0.7),
])
))
addBall()
function:
addBall()函数:
func addBall(_ screenWidth: CGFloat, _ screenHeight: CGFloat) {
// code
}
on the line where it runs ballGen.addBall()
it gives the error:
在它运行ballGen.addBall()的行上它给出了错误:
cannot convert value of type '()' to expected argument '() -> void'
无法将'()'类型的值转换为预期的参数'() - > void'
What is going wrong here?
这里出了什么问题?

Your addBall function is not returning anything. You should do it like this:
你的addBall函数没有返回任何东西。你应该这样做:
func addBall(_ screenWidth: CGFloat, _ screenHeight: CGFloat) -> SKAction {
return SKAction
}
