SKSpriteNode : Handling Collision during SKAction

Vote count:

0

I'm making a little game, and I'm now stuck with the following problem.

I'm running an action (followPath type) on a particular node :

let followTrack: SKAction = SKAction.followPath(ballPath!.CGPath, duration: ACTION_SPEED)
movingBall.runAction(followTrack)

But during the animation, if the node collide with another one (like a wall for exemple), the animation stops and there is no collision animation.

I tried some things like :

func didBeginContact(contact: SKPhysicsContact) {
    var firstBody: SKPhysicsBody = contact.bodyA
    var secondBody: SKPhysicsBody = contact.bodyB

    firstBody.node?.removeAllActions()
    secondBody.node?.removeAllActions()
}

But there is no collision either (I guess that's because velocity is (0,0))

Is there anyway to handle this case ? (I don't especially need a swift answer, an objective-C or generic answer would be great too !)
