What is the difference between setScale and SKSpriteNodes in SpriteKit and Swift?

Question

I tried to set the size SKSpriteNodefrom a PNG image (OK with this, just a:

test = SKSpriteNode(imageNamed: "myImage")

But when it comes to changing it, I'm not sure what I should use test.setScaleor test.size. What is the difference and when should I use each of them?

Answer 1

setScale():

Sets the xScale and yScale node properties . These two parameters are the scaling factor that multiplies the width (for xScale) and height (for yScale) of the node and its children.

Code example:

spaceship.setScale(0.50) // decreased scale to it half size

---

size(): ( ) .

:

spaceship.size = CGSizeMake(100.0, 70.0) // Re-size the dimensions to these values

---

setScale size?

Answer 2

spriteNode, .setScale .xScale .yScale, ..size UIKit.

theNode.xScale = 2.0
theNode.yScale = 2.0

Answer 3
