Flipped x-scale breaks collision handling (SpriteKit 7.1)

Question

I use SKNode\'s xScale property to flip my sprites horizontally. Now, after updating iOS to version 7.1 horizontal flip causes my objects to sink inside the ground. (See ani

Answer 1

I encountered this problem a couple of days ago. I wanted to invert the sprite based on it's movement (right or left) and found that setting xScale disables any collisions/contacts.

However, I used this line every time I set the xScale property and everything went back to normal.

node.xScale = -1.0
node.physicsBody = node.physicsBody;
