applyImpulse(_:at:)
Applies an impulse to a specific point of a physics body.
Declaration
func applyImpulse(_ impulse: CGVector, at point: CGPoint)Parameters
- impulse:
A vector that describes how much momentum to impart to the body. The impulse is measured in Newton-seconds.
- point:
A point in scene coordinates that defines where the impulse was applied to the physics body.
Discussion
Because this impulse is applied to a specific point on the object, it may change both the body’s velocity and angular velocity.
