                    GSKCombineRotation

Returns the resulting rotation when applying firstRotation, then secondRotation.

Objective-C

extern GSKRotation GSKCombineRotation(GSKRotation firstRotation,
                                      GSKRotation secondRotation)

Swift

func GSKCombineRotation(_ firstRotation: GSKRotation, _ secondRotation: GSKRotation) -> GSKRotation


                    
                    
                    GSKSubtractRotation

Returns the resulting rotation when applying firstRotation, then subtracting secondRotation.

Objective-C

extern GSKRotation GSKSubtractRotation(GSKRotation firstRotation,
                                       GSKRotation secondRotation)

Swift

func GSKSubtractRotation(_ firstRotation: GSKRotation, _ secondRotation: GSKRotation) -> GSKRotation
