I am new to SpriteKit, and I am trying to make a simple game. however, when trying to integrate gravity, the player foes not hit the floor, but instead falls behind (despite having the same zPosition). I would like to know what I need to have the floor and player collide. I have currently set the collisionBitMask and categoryBitMask, have them on the same zPosition, and have gravity turned off of the floor, but enabled on the player. is there anything else that needs to be done?
