Actions Documentation

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Destroy()

This action closes the window.

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)

GetClipboard()

Not all implementations support a clipboard, but all displays support the operations so that they can be called everywhere. If an implementation supports a clipboard, the appopriate system mechanisms are handled automatically.

Return

text:

GetConfiguration()

This action returns the AndroidConfiguration being used by this AndroidDisplay.

Return

Libraries.Game.ApplicationConfiguration:

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

GetHeight()

This action returns the height of the AndroidDisplay.

Return

integer:

GetPixelScaleFactor()

This action returns the ratio between screen coordinates and pixels.

Return

number:

GetResize()

This action returns whether the AndroidDisplay is resizable or not. This will always return false.

Return

boolean:

GetSecondsBetweenFrames()

This action tests how many seconds have passed since the last time that the time was updated.

Return

number:

GetSecondsSinceStart()

This action returns the number of seconds that have passed since the game was started.

Return

number:

Example

use Libraries.Game.Game
use Libraries.Game.GameDisplay
use Libraries.Game.GameStateManager

class Main is Game

    GameDisplay display = undefined
    integer frameCount = 0

    action Main
        StartGame()
    end

    action CreateGame
        GameStateManager manager
        display = manager:GetGameDisplay()
    end

    action Update(number seconds)
        frameCount = frameCount + 1
        if frameCount = 30
            number time = display:GetSecondsSinceStart()
            output "The game has been running for " + time + " seconds."
        end
    end
end

GetWidth()

This action returns the width of the AndroidDisplay.

Return

integer:

IsAvailable()

The IsAvailable action returns whether or not a display is available to draw on. If no display is available, actions that try to create or draw graphics (such as loading a Drawable) will create an error. This will return false if called before StartGame() is called in the Game class, and will typically return true after the game has been started.

Return

boolean:

ReloadResources()

This action reloads resources that were lost due to context loss (most commonly due to an app being minimized). This is called automatically by the engine when needed.

RequestRendering()

This action tells the AndroidDisplay to render to the screen.

SetClipboard(text value)

Not all implementations support a clipboard, but all displays support the operations so that they can be called everywhere. If an implementation supports a clipboard, the appropriate system mechanisms are handled automatically.

Parameters

  • text value

SetConfiguration(Libraries.Game.ApplicationConfiguration conf)

This action sets the AndroidConfiguration being used by the game, which includes data for the screen. If the given ApplicationConfiguration is not an AndroidConfiguration, an error will be thrown.

Parameters

SetDisplayMode(integer width, integer height, boolean fullscreen)

This action normally sets the width and height of the AndroidDisplay, but games on Android devices always fill the screen, so this does nothing. The action will return false to indicate that no action was taken.

Parameters

  • integer width
  • integer height
  • boolean fullscreen

Return

boolean:

SetVSync(boolean vsync)

This action sets vSync on or off for the AndroidDisplay.

Parameters

  • boolean vsync

WasResized()

This action returns whether or not the AndroidDisplay has been resized.

Return

boolean:
