Goal• Learn the process• Take current game straight to iOS to see how it
performs• Have an app on Apple App store

Optimizing Apps for Mobile
What works for web may not work for mobile• Vector vs. Bitmap
– Processor intensive vs. file size– Animation – Blitting over Tweening– Animation only when needed and when little else is
going on

– Processor intensive vs. file size– Animation – Blitting over Tweening– Animation only when needed and when little else is

• OOP vs. fast code– Big MVC architectures slow down mobile apps– Balance between reusable code and performance

Optimizing Apps for Mobile
Some ideas will help any app - mobile or online1. Declaring variables before loops

2. Data type variables – Double Advantage– App runs faster and takes up less memory

4. Object Pooling– If it has been made. Don’t delete and recreate if
needed
– Creating/Destroying objects is memory intensive and slows system down

• Created Test to check speed of processor- Math problem run 1 million times- Returns how long it took to run- Based on testing of devices, number indicates how many
items to animate on-screen at once
