There is so much written about performance but much of what I found is done with broad strokes and I'm curious about some actions people do specifically.
For example; on a platform game, would you suggest to delay create game objects that have collision (e.g., coins and other game characters) when they are on a hidden level or off screen. Example, create characters only on the level the user is playing or create the characters as the screen gets close to scrolling them into view?
I'm curious...
