Questions tagged [skphysicsjoint]

An SKPhysicsJoint object connects two physics bodies together so that they are simulated together by the physics world. You never instantiate objects of this class directly; instead, you instantiate one of the subclasses that defines the kind of joint you want to make. This class implements the common properties of the joint classes provided by Sprite Kit.

Is lowerAngleLimit on SKPhysicsJointPin broken?

I have never gotten the upper/lower angle limits to work properly on SKPhysicsJointPin objects, and I think I've finally figured out why: if the lowerAngleLimit is set to a negative value, it breaks every time. It only works correctly with…

Swift creating physics joint

I am trying to work with SpriteKit and create an elbow joint that bends to allow movement of another joint. The problem is that when I create the joint, the parts all rotate 360 degrees as I swipe across the screen to action the movement, so there…

How do you pass through a Spritekit joint anchor?

I have tree that is built out of a series of joints. The anchor is the base/stump of the tree. My hero is currently not able to walk through the anchor. Setting collisionBitMask = 0 isn't working for the anchor but that approach does work for the…
