Used to configure the RoboVM platform.

Field Summary

Fields

Modifier and Type	Field and Description
int	frameInterval Indicates the frequency at which the game should be rendered (and updated).
org.robovm.apple.glkit.GLKViewDrawableColorFormat	glBufferFormat Configures the format of the GL framebuffer.
boolean	interpolateCanvasDrawing If true, calls to CanvasImage.draw() on a retina device using a non-retina image as the source will use the default interpolation defined for CGBitmapContext.
boolean	iPadLikePhone If true, an iPad will be treated like a 2x Retina device with resolution 384x512 and which will use @2x images.
int	openALSources The number of audio channels to reserve for OpenAL.
org.robovm.apple.uikit.UIInterfaceOrientationMask	orients Indicates which orients are supported by your app.
java.lang.String	storageFileName Dictates the name of the temporary file used by RoboStorage.
int	targetFPS The desired frames per second for the app.

Field Detail

orients

public org.robovm.apple.uikit.UIInterfaceOrientationMask orients

Indicates which orients are supported by your app. You should also configure this information in your Info.plist file.

iPadLikePhone

public boolean iPadLikePhone

If true, an iPad will be treated like a 2x Retina device with resolution 384x512 and which will use @2x images. A Retina iPad will also have resolution 384x512 and will use @4x images if they exist, then fall back to @2x (and default (1x) if necessary). If false, iPad will be treated as a non-Retina device with resolution 768x1024 and will use default (1x) images, and a Retina iPad will be treated as a Retina device with resolution 768x1024 and will use @2x images.

frameInterval

public int frameInterval

Indicates the frequency at which the game should be rendered (and updated). Defaults to one, which means one render per device screen refresh (maximum FPS). Higher values (like 2) can be used to reduce the update rate to half or third FPS for games that can't run at full FPS. As the iOS docs say: a game that runs at a consistent but slow frame rate is better than a game that runs at an erratic frame rate.

interpolateCanvasDrawing

public boolean interpolateCanvasDrawing

If true, calls to CanvasImage.draw() on a retina device using a non-retina image as the source will use the default interpolation defined for CGBitmapContext. This will potentially make scaled non-retina images look better, but has performance and pixel accuracy implications.

openALSources

public int openALSources

The number of audio channels to reserve for OpenAL. This dictates the number of simultaneous sounds that can be played via OpenAL. It can't be higher than 32, and can be reduced from the default of 24 if you plan to play a lot of compressed sound effects simultaneously (those don't go through OpenAL, they go through AVAudioPlayer, and I presume AVAudioPlayer competes with OpenAL for sound channels).

timeForTermination

public float timeForTermination

Seconds to wait for the game loop to terminate before terminating GL and AL services. This is only used if PlayN is integrated into a larger iOS application and does not control the application lifecycle.

glBufferFormat

public org.robovm.apple.glkit.GLKViewDrawableColorFormat glBufferFormat

Configures the format of the GL framebuffer. The default is RGBA8888, but one can use RGB565 for higher performance at the cost of lower color fidelity.

targetFPS

public int targetFPS

The desired frames per second for the app. This controls the frequency of update and paint calls to your app. Safe values are 30 or 0. I'm not sure that iOS will honor other arbitrary frame rates.

storageFileName

public java.lang.String storageFileName

Dictates the name of the temporary file used by RoboStorage. Configure this if you want to embed multiple games into your application.
