How To Create Array Of SKSpriteNodes? (swift, spritekit)

问题

I have 12 ball sprites all of which have the same attributes. Is it possible to put them all in an array so I dont have to keep typing....

      ball1.size.......
      ball2.size........
      ball3.size......

Etc.

I would like to create an array called allBalls and then just change every ball through one line of code like shown...

      allBalls.size.....

回答1:

To create an array of SKSpriteNodes you could do the following:

let allBalls = [ball1, ball2, ball3] // Of type Array<SKSpriteNode>

Then iterate through the array and change the size property of each ball:

for ball in allBalls {
    ball.size = // Whatever size you want.
}
