Answer 1

calculateAccumulatedFrame is a method that returns the largest rectangle that includes all of the SKNodes children. This should be able to solve your problem

BUT It might be better creating your own polygon which represents the area where all the particles are usually held and doing a test with that, It gives you more accuracy and gives u more control
