I want my sprites collisions and contacts to be detected, but I don't want them to move dynamically (I just need to know that they've touched).
physicsBodys follow the physics world set up by my scene. When they collide, they interact with the physicsWorld, which has a default gravity that pulls them downward.
To fix this issue, in the
init method of my Scene I set
self.physicsWorld.gravity = CGVectorMake(0, 0)
Dynamic still has to be set to true because I want the physics bodies to interact with the physics world, but I don't want the physics world to effect them, so this is the resolution.
