CROSS PLATFORM


HOW BAD CAN IT BE?


HOW BAD CAN IT BE?

• Radically different performance• Radically different form factors• Radically different input methods• Radically different monetization methods


BUT FIRST!!!


UNITY’S NOT SPECIALAT LEAST NOT IN THIS CASE



Any technique you would use for any engine, even

your own, can be used in Unity



Any technique you would use for any engine, even

your own, can be used in Unity

GOLDEN RULE


COREY’S GOLDEN RULE


COREY’S GOLDEN RULE

When it comes to designing an experience, design

specifically for your target platform


INPUT


CLEVER INPUT REFERENCE

Separate intent from man-machine interface


CLEVERER INPUT REFERENCEpublic class ExampleClass : MonoBehaviour {

void Update() {if (Input.GetKey(

KeyCode.UpArrow))Jump();

}}

}

http://docs.unity3d.com/ScriptReference/KeyCode.UpArrow.html


CLEVER INPUT REFERENCE TOpublic class ExampleClass : MonoBehaviour {

void Update() {if (InputManager.GetIntent(Intents.Jump

))Jump();

}}

}





CLEVER INPUT REFERENCE TOpublic class InputManager : MonoBehaviour {

void FixedUpdate() { if (Input.GetKey(

KeyCode.UpArrow))intents[Intents.Jump] =

true;}

}}






CLEVER INPUT REFERENCE TOpublic class InputManager : MonoBehaviour {

void FixedUpdate() { if (IsGestureFired(“swipe”, data)

&& data.handId == 1)intents[Intents.Jump] =

true;}

}}




ASPECT RATIO & RESOLUTION


ASPECT RATIO

Design your layout system to handle change in aspect

ratio


ASPECT RATIO


RESOLUTION


RESOLUTION

Use appropriate sprites for the screen resolution


RESOLUTION


RESOLUTION

What resolution should I develop in?


MINIMUM SPECIFICATIONS


MIN SPECS MATTER


MIN SPECS MATTER

Don’t do all of your development on some über

Maschine


PERFORMANCE


GPU

Custom rendering requires custom ports for each

architecture


MEMORY

Use as little as possible


MEMORY


PLUGINS

Trade off between performance and portability


SERVICES


ASSET STORE

Trade off between new functionality and portability

(maybe)


CLOUD BUILD


RANDOM ADVICE


LEAD WITH YOUR OFF FOOT

If you want to ship on multiple platforms

simultaneously, make your lead platform the most

complex


GRASS IS ALWAYS GREENER

If you plan on shipping to different regions, plan for it
