Libraries.Game.Graphics.Fonts.FontStrategy Documentation

The FontStrategy class is used to call the appropriate font actions based on the font system. In normal use cases, this is FreeType on Windows and Mac, and QuorumFont on Anrdoid and Linux. Most users will not need to use this class directly, as the action calls are done within the Font class.

Example Code

use Libraries.Game.Graphics.Font
use Libraries.Game.Graphics.Label
use Libraries.Game.Game

class Main is Game
    action Main
        StartGame()
    end

    action CreateGame
        Font font
        Label label
        if not font:IsFontAvailable("Veranda")
            output "The font could not be found!"
            return now
        end
        font:LoadFont("Veranda")
        font:SetSize(18)
        label:SetFont(font)
        Add(label)
    end
end

Actions Documentation

ChangeSubFont(text style)

Parameters

  • text style

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)

Dispose()

This action will release the resources used by a loaded font. The Font object will no longer be usable until another font is loaded.

Example

use Libraries.Game.Graphics.Font
use Libraries.Game.Game

class Main is Game
    action Main
        StartGame()
    end

    action CreateGame
        Font font
        font:LoadFont("Arial")
        font:Dispose()
    end
end

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)

GetAngle()

This action will return the current angle of the font. The default angle is 0 degrees.

Return

number: Returns the current angle of the font.

Example

use Libraries.Game.Graphics.Font
use Libraries.Game.Game

class Main is Game
    action Main
        StartGame()
    end

    action CreateGame
        Font font
        output "The font has an angle of " + font:GetAngle() + " degrees."
    end
end

GetAvailableFonts()

This action will return an array of all files found in the system's default font folder.

Return

Libraries.Containers.Array: Returns an array with all the font files on the system.

    action CreateGame
        Font font
        Array<File> fontFiles = font:GetAvailableFonts()
        integer index = 0
        output "The following fonts are available on the system: "
        repeat fontFiles:GetSize() times
            File temp = fontFiles:Get(index)
            output temp:GetPath()
            index = index + 1
        end
