Let's say I have multiple levels in my game. I have one event sheet that controls the basic code for every level (controls, AI, etc) called Game-Events. I also have level specific events that I have in a separate sheet (eg special enemies) that is called Level-x-Events
Which is better, assigning the Game-Events sheet to the layout, and then including the Level-x-Events, or assigning the Level-x-Events and including the Game-Events?
Is there a difference in performance?
