  you should have to setup collision for each and every part you needed for collision at the other hand if your object is not much complex say you need to find whether player has collided from top of from left some simple calculation l=with chking x and y position will also work

  you could add a line in the init function of the class which adds the object to some global table, e.g. define a global table outside of the Class
  objectsFromClass={}
  and then inside Class:init()
  add the line
  table.insert(objectsFromClass,self)
  also don't forget to have a destroy function for the class (called when an object is removed) where you remove self from this table.
  
  this way you will have a table objectsFromClass of all objects of class Class. And then you can always sweep this table and check collision to the objects in it one by one (either box2d, or checking x-y position or using hittestpoint) - maybe for box2d you don't need to do that manually, i never used it, so i don't know.

  @Tstar_one depending on the complexity of the shapes you have, you can also use box2d or TNT Collision engine

  @Tstar_one, I had problems of complexity using box2d and I went on TNT collision engine with ease and success
