In my game the speed increases every time the score node is contacted and it works up to a certain speed and then the collision with the score node is not detected. Use the appropriate SKSpriteNode initializer, if you don't want to use a texture you should use this. 2. SpriteKit Collision Detection. I ran into a problem today when I was trying to write the code for the collision detection. Note: I have everything set-up with the coins spawning and the collision works but when the player collides the game ends. I am using Spritekit which basically have some balls colliding, but I need to implement a method where if the ball is one side of the screen, it is of type "A" and if it is towards the right side of the screen it is type "B".
