orient(to:offset:)
Creates a constraint that forces a node to rotate to face a fixed point.
Declaration
class func orient(to point: CGPoint, offset radians: SKRange) -> SelfParameters
- point:
A point in the node’s parent’s coordinate system.
- radians:
An offset that is added to the Zrotation value after it is calculated.
Return Value
A new constraint.
Discussion
Each time when constraints are applied, a new angle is calculated so that a line projected at this angle would point at the target point. This angle is added to the values specified in the radians property to create a new range. Finally, the node’s zRotation value is clamped to fit inside this range.
