methodology - Switching between levels, re-initialize existing structure or create new one?


This is something I've been wondering for quite a while. When building games that exist out of multiple levels (platformers, shmups etc) what is the prefered method to switch between the levels?


Let's say we have a level class that does the following:



  • Load data for the level design (tiles), enemies, graphics etc.

  • Setup all these elements in their appriopate locations and display them

  • Start physics and game logic


I'm stuck between the following 2 methods:


1: Throw away everything in the level class and make a new one, we have to load an entirely new level anyway!



2: pause the game logic and physics, unload all currents assets, then re-initialize those components with the level data for the new level.


They both have their pros and cons. Method 1 is alot easier and seems to make sense since we have to redo everything anyway. But method 2 allows you to re-use exisiting elements which might save resources and allows for a smoother transfer to the new level.
