Why Programming Patterns Are Important for Game Development?

GOOD GAME BAD

PERFORMANCE

Memory is a scarce

resource specially at

mobile.

Games use much more RESOURCES

than any other kind of apps.

OBSERVER

OBSERVER

Observer Description

  As part of the MODEL-VIEW-CONTROLLER

  Java = Observer

  C# = Event

  CHALLENGE = Achivements triggered by a Bunch of Aspects at the Game Play.

Anounce to any suscribed instance that something has occurred.

PART OF MVC HANDLES EVENTS EFFECTIVELY ANNOUCE TO ANY SUSCRIBER THAT SOMETHING HAS OCCURRED

MANAGEMENT OF CHARACTER STATE FOR FIXED STATES ALL CHARACTER BEHAVIOR IN ONE CLASS

OBJECT POOL

POOL OBJECT

Object Pool Description

Improve performance and memory usage by using a fixed pool of objects.

  A best alternatite to the create-destroy strategy at game development

  Reduce Memory Fragmentation

Useful for multiple enemies.

Garbage Collector will become slower as memory usage increases.

IMPROVE MEMORY PERFORMANCE BEST TO CREAT-DESTROY REDUCE MEMORY FRAGMENTATION
