Swift SpriteNode Initial Angle

Question

I'm trying to set the initial angle of my sprite to be 90 degrees. I don't want to call an action, is there a way of setting the angle parameter of a sprite as you do with the position?

Answer 1

zRotation

You can use the zRotation property of SKNode which accept radiants

Degrees to Radiants

There's a useful extension for that

extension Int {
    var degreesToRadians: Double { return Double(self) * M_PI / 180 }
    var radiansToDegrees: Double { return Double(self) * 180 / M_PI }
}

sprite.zRotation = CGFloat(90.degreesToRadians)

From the Api Doc

The Euler rotation about the z axis (in radians).

The default value is 0.0, which indicates no rotation. A positive value indicates a counterclockwise rotation. When the coordinate system is rotated, it affects the node and its descendants. The rotation affects the node’s frame property, hit testing, rendering, and other similar characteristics.
