**Original comment by Sasha Szpakowski (Bitbucket: [slime73](https://bitbucket.org/slime73), GitHub: [slime73](https://github.com/slime73)).** ---------------------------------------- You also wouldn't be able to explicitly set the density during Fixture creation with those (although there is `Fixture:setDensity`). It...

**Original comment by Bruce Hill (Bitbucket: [spilt](https://bitbucket.org/spilt), GitHub: [spilt](https://github.com/spilt)).** ---------------------------------------- One aspect of the current API that I find pretty user-unfriendly is collision groups/categories/masks. I think my ideal collision API...

**Original comment by adn adn (Bitbucket: [adonaac](https://bitbucket.org/adonaac), ).** ---------------------------------------- SpriteKit seems to do with SKPhysicsBody the same idea I have with Colliders. Unity also does something similar although not from...

**Original comment by Sasha Szpakowski (Bitbucket: [slime73](https://bitbucket.org/slime73), GitHub: [slime73](https://github.com/slime73)).** ---------------------------------------- Yeah, I also noticed SpriteKit has fields: https://developer.apple.com/library/mac/documentation/SpriteKit/Reference/SKFieldNode_Ref/index.html#//apple_ref/occ/cl/SKFieldNode https://developer.apple.com/library/mac/documentation/SpriteKit/Reference/SKPhysicsWorld_Ref/index.html#//apple_ref/occ/instm/SKPhysicsWorld/sampleFieldsAt: Although that might be a thing for a separate bitbucket issue.
