        // Once we have the options, we can modify them to adjust how our Controls appear by default.
        options:SetButtonBackgroundColor(color:Pink())
    end
end

GetInterfaceScale()

The GetInterfaceScale action returns the scale of the user interface. Larger scaling values make each interface component larger. When the interface is scaled in this way, components that can be re-rendered at a higher resolution (such as fonts) will do so. Note that this represents the standard scale in use by the default 2D layer, and it will not necessarily reflect the scale of every single component.

Return

number: The current interface rendering scale.

Example

use Libraries.Game.Game
use Libraries.Interface.Layouts.FlowLayout
use Libraries.Interface.Controls.Button

        SetSkybox(skybox)
    end

end

GetSkybox()

The GetSkybox action will return the Skybox in use by the currently active Layer3D. By default, a Layer3D does not start with a Skybox, so using this on a Layer3D that hasn't had a Skybox assigned to it will return undefined.

InitializeLayers()

This action sets the game to use the default layers. The default layers consist of a single 3D layer, with a single 2D layer on top of it. This action is automatically called by the Game engine during StartGame. Users may use it again to "reset" the layers to default, but generally users will not need to use this action directly.

IsColliding()

This allows us to know if collisions are on or off for the layer.

Return

boolean:

IsWindowFocused()

This action determines whether or not the main application window has the focus on desktop platforms. On non-desktop platforms, this always returns false.

Return

boolean:

Return

boolean: True if the window is maximized, false otherwise.

IsWindowMinimized()

On desktop platforms, this action returns true if the application is currently minimized, or false otherwise. On other platforms, this always returns false.

Return

boolean: True if the window is maximized, false otherwise.

LoadScene(Libraries.Game.Scenes.Scene scene)

    end

    action CreateGame
        Scene scene
        File file
        file:SetPath("Scenes/Scene.qs")
        scene:Load(file)
        LoadScene(scene)
    end

    action Update(number seconds)
    end
end

LoadScene(text path)

This loads a scene file into the game. This is a helper action for loading a scene.

Parameters

  • text path

Example

use Libraries.Game.Game
use Libraries.Game.Scenes.Scene
use Libraries.System.File

class Main is Game
    action Main
        StartGame()
    end

    action CreateGame
        LoadScene("Scenes/Scene.qs")
    end

    action Update(number seconds)
    end
end

LoadScene(Libraries.System.File file)

This loads a scene file into the game.

Parameters

Example

use Libraries.Game.Game
use Libraries.Game.Scenes.Scene
use Libraries.System.File

class Main is Game
    action Main
        StartGame()
    end

    action CreateGame
        File file
        file:SetPath("Scenes/Scene.qs")
        LoadScene(file)
    end

    action Update(number seconds)
    end
end

MoveForward()

OnExit()

The OnExit action is called when the Game is about to close, either because the Exit action was called or because the user requested it (for example, by attempting to close the window on desktop platforms). The action must return a boolean value representing whether or not the application should proceed to shut down. If the returned value is true, the application will shut down. If it is false, the program will continue running instead. Users should always make sure that it is possible for OnExit to return true in some cases to allow the user to close the program. This action doesn't prevent the Game from shutting down on all platforms. For example, mobile devices typically don't allow an application to keep itself open after a close has been requested.

Return

boolean: True if the Game should be allowed to close, false if the Game should continue running.

Example

use Libraries.Game.Game

class Main is Game
    integer countdown = 3

    action Main
        StartGame()
    end

    action OnExit returns boolean
        if countdown <= 0
            return true
        end
        output "Countdown: " + countdown
        countdown = countdown - 1
        return false

SetColliding(boolean collide)

This allows us to turn collisions on or off for the layer.

Parameters

  • boolean collide

SetColorFilter(Libraries.Game.Graphics.Color color)

Using SetColorFilter will tint all drawn objects on the currently active Layer2D that do not have their own custom color tint. For example, using a red color filter will make all objects drawn on the currently active Layer2D to appear to be more red.

Parameters

Example

use Libraries.Game.Game
use Libraries.Game.Graphics.Drawable
use Libraries.Game.Graphics.Color

class Main is Game

    Drawable bunny
    Color tint

    action Main
        StartGame()
    end

    action CreateGame
        bunny:Load("Rabbit.png")
        Add(bunny)
        
        tint = tint:Maroon()

        SetColorFilter(tint)
    end
end

SetColorFilter(number red, number green, number blue, number alpha)

SetColorFilter can also be called using four number parameters instead of a color object. The four parameters are the red, green, blue, and opacity of the filter, respectively. All four of the parameters should be between 0 and 1, representing between 0% and 100% of that color component. For example, a value of 0 for red means that the tinting color will have no red, while a value of 1 will have all red components. An opacity of 0 is totally transparent, while an opacity of 1 will be totally visible.

Parameters

  • number red: The red component of the color filter to apply.
  • number green: The green component of the color filter to apply.
  • number blue: The blue component of the color filter to apply.
  • number alpha: The alpha (or transparency) component of the color filter to apply.

Example

use Libraries.Game.Game
use Libraries.Game.Graphics.Drawable

class Main is Game

    Drawable bunny

SetInterfaceOptions(Libraries.Interface.Options.InterfaceOptions options)

This action sets the InterfaceOptions being used by the game, providing default colors and properties for Controls. This affects all Controls currently in the game or that are added later.

Parameters

Example

use Libraries.Game.Game
use Libraries.Interface.Options.DarkModeOptions

class Main is Game

    action Main
        StartGame()
    end

    action CreateGame
        // DarkModeOptions is one kind of InterfaceOptions we could use for our game.
        // It will use darker colors to draw interface elements, like Buttons, by default.
        DarkModeOptions options
        SetInterfaceOptions(options)
    end
end

SetInterfaceScale(number scale)

The SetInterfaceScale action sets the scale of the user interface. Larger scaling values make each interface component larger. When the interface is scaled in this way, components that can be re-rendered at a higher resolution (such as fonts) will do so.

Parameters

  • number scale: The new interface rendering scale to use.

Example

use Libraries.Game.Game
use Libraries.Interface.Layouts.FlowLayout
use Libraries.Interface.Controls.Button

class Main is Game

    action Main
        StartGame()
    end

    action CreateGame
        FlowLayout layout
        SetLayout(layout)

        Button button1
        button1:SetName("My Button")
        Add(button1)

        SetInterfaceScale(2.0)
    end
end

SetLayer(integer index, Libraries.Game.Layer layer)

This action will set the given index to use the given Layer, overwriting any Layer that was already at that index. This will not force disposal of any resources that the Layer's items may have been using.

Parameters

  • integer index: The index to set the Layer at.
  • Libraries.Game.Layer: The Layer to be added to the Game. use Libraries.Game.Game use Libraries.Game.Layer2D class Main is Game action Main StartGame() end action CreateGame // This will set the layer at index 0, making it the first layer drawn. Layer2D layer SetLayer(0, layer) end action Update(number seconds) end end

    action Update(number seconds)
        // Pressing the spacebar will set the game to use the desktop's resolution.
        // If the boolean is false, the cameras will not be adjusted to the new screen size,
        // making them appear to be zoomed in on the original area.
        // If the boolean is true (or omitted), the cameras will be adjusted to view the
        // new size of the screen. Drawables will remain at their original size and position.
        if monitor:IsKeyPressed(keys:SPACE)
            ScreenResolution resolution = GetDesktopResolution()
            SetScreenResolution(resolution, false)
        end
        // Using the desktop resolution will typically make the game go fullscreen.
        // To exit the game, the user can press the ESCAPE key.
        if monitor:IsKeyPressed(keys:ESCAPE)
            Exit()
        end
    end
end

SetScreenResolution(Libraries.Game.ScreenResolution resolution)

This action will set a game running on a desktop platform to use the given ScreenResolution. This will have no effect on non-desktop platforms. Using this action will also adjust the size of the cameras on the default 2D and 3D layers to match the new screen size. To change the screen size without changing the cameras, use SetScreenResolution(ScreenResolution, false).

Parameters

Example

use Libraries.Game.Game
use Libraries.Game.ScreenResolution
use Libraries.Game.InputMonitor
use Libraries.Interface.Events.KeyboardEvent

class Main is Game

    InputMonitor monitor
    KeyboardEvent keys

    action Main
        StartGame()
    end

    action CreateGame
        ScreenResolution resolution = GetDesktopResolution()
        SetScreenResolution(resolution)
    end

    action Update(number seconds)
        // Using the desktop resolution will typically make the game go fullscreen.
        // To exit the game, the user can press the ESCAPE key.
        if monitor:IsKeyPressed(keys:ESCAPE)
            Exit()
        end
    end
end

SetScreenSize(integer width, integer height, boolean adjustCameras)

This action sets windowed size of the game (the default size is 800 by 600). This action can be called before calling StartGame() to set the initial window size. If this action is used when the game is in fullscreen, it will return it to windowed mode. If the game is already running and the boolean parameter is set to true, then the default cameras will be adjusted to fit the new window size. If the value is set to false, the cameras will not be adjusted.

Parameters

  • integer width: The screen width.
  • integer height: The screen height.
  • boolean adjustCameras: True to adjust the default cameras to the new dimensions, false to keep the cameras the same.

Example

use Libraries.Game.Game

class Main is Game

    action Main
        SetScreenSize(1024, 800)
        StartGame()
    end
end

SetScreenSize(integer width, integer height)

This action sets windowed size of the game (the default size is 800 by 600). This action can be called before calling StartGame() to set the initial window size. If this action is used when the game is in fullscreen, it will return it to windowed mode. If the game is already started, this action will adjust the cameras on the default 2D and 3D layers to correspond to the new window size.

Parameters

  • integer width: The screen width.
  • integer height: The screen height.

Example

use Libraries.Game.Game

class Main is Game

    action Main
        SetScreenSize(1024, 800)
        StartGame()
    end
end

SetSimulationThreshold2D(number threshold)

The GetSkybox action will return the Skybox in use by the currently active Layer3D. By default, a Layer3D does not start with a Skybox, so using this on a Layer3D that hasn't had a Skybox assigned to it will return undefined.

Parameters

  • number threshold

Example

use Libraries.Game.Game
use Libraries.Game.Graphics.Skybox

class Main is Game

    action Main
        StartGame()
    end

    action CreateGame
        Skybox skybox
        // Assuming we have a folder named "skybox" containing our six images.
        skybox:Load("skybox/right.jpg", "skybox/left.jpg", "skybox/top.jpg", "skybox/bottom.jpg", "skybox/front.jpg", "skybox/back.jpg")
        SetSkybox(skybox)

        // We can get the Skybox back from the layer using GetSkybox().
        Skybox currentSkybox = GetSkybox()
    end

end

SetSkybox(Libraries.Game.Graphics.Skybox skybox)

The SetSkybox action will set the currently active Layer3D to use the given Skybox.

Parameters

Example

use Libraries.Game.Game
use Libraries.Game.Graphics.Skybox

class Main is Game

    action Main
        StartGame()
    end

    action CreateGame
        Skybox skybox
        // Assuming we have a folder named "skybox" containing our six images.
        skybox:Load("skybox/right.jpg", "skybox/left.jpg", "skybox/top.jpg", "skybox/bottom.jpg", "skybox/front.jpg", "skybox/back.jpg")
        SetSkybox(skybox)
    end

end

SetStartingCoordinates(integer x, integer y)

Parameters

  • integer x
  • integer y

SetVSync(boolean vSync)

This action enables or disables vSync in the game. Passing a value of true enables it, a value of false disables it. vSync is enabled by default. This action should be called before calling StartGame(). This option is only used when the game is run on desktops.

Parameters

  • boolean vSync: Whether or not vSync should be enabled.

Example

use Libraries.Game.Game

class Main is Game

    action Main
        SetVSync(false)
        StartGame()
    end
end

SetWebContainerID(text id)

The SetWebContainerID action determines which container to use on a webpage. When the game runs, it will be displayed in the designated container. If no container ID is given, the engine will attempt to find a container with the default ID, "QuorumUIContainer". If the engine can't find a container with the set ID, it will not run. This action has no effect if called inside a game that isn't being run online.

Parameters

  • text id: The ID of the canvas to display the game in.

Example

use Libraries.Game.Game
use Libraries.Game.WebConfiguration

class Main is Game

    action Main
        SetWebContainerID("myContainer")
        StartGame()
    end
end

SetWindowMaximized(boolean maximized)

This action maximizes the screen, or restores a maximized screen to its original size. If this is called before the Game window opens, it will launch the window in maximized mode. If the Game is being displayed in full screen, this action will do nothing. This action is only for desktop platforms -- on other platforms, it does nothing.

Parameters

  • boolean maximized: True to maximize the window, or false to restore it to its original size.

Example

use Libraries.Game.Game

class Main is Game

    action Main
        SetWindowMaximized(true)
        StartGame()
    end
end

SetWindowMinimized(boolean minimized)

This action minimizes the screen, or restores a minimized screen to its original size. This action is only for desktop platforms -- on other platforms, it does nothing.

Parameters

  • boolean minimized: True to minimize the window, or false to restore it to its original size.

Example

use Libraries.Game.Game

class Main is Game

    action Main
        StartGame()
    end

    action CreateGame
        SetWindowMinimized(true)
    end
end

StartGame()

The StartGame action will start your game. Specifically, it does this: 1. Creates the Game window. 2. Calls the CreateGame() action. 3. Repeatedly calls Update() until Exit() is called or the window is closed. If you are using any actions to change the starting settings of the window, call those before calling StartGame().

Example

use Libraries.Game.Game

class Main
    action Main
        Game game
        Game:StartGame()
    end
end

TurnLeft()

TurnRight()

TurtleCommands()

Update(number time)

The Update action is where most of the game's logic goes. The code inside Update will be called on every frame of the game. In other words, for every time a picture is drawn on the screen, the Update action is called. The number parameter is the amount of seconds that has passed since the last time Update was called.

Parameters

  • number time: The number of seconds that have passed since the last time Update was called.

Example

use Libraries.Game.Game

class Main is Game

    action Main
        StartGame()
    end

    // It is very important when making our own Update action that it has
    // the time parameter! If we don't have it, it won't be called.
    action Update(number time)
        output "Update was called!"
    end
end

UseDesktopResolution(boolean adjustCameras)

UseDesktopResolution will set the game to use the same display settings as the desktop's current screen resolution (independent of the game). This is only effective when used on desktop platforms - on other platforms, this will do nothing. If the boolean parameter is set to true, then this action will also adjust the size of the cameras on the default 2D and 3D layers to match the new screen size. If the parameter is false, then the cameras will not be changed.

Parameters

  • boolean adjustCameras: True to adjust the default cameras to the new dimensions, false to keep the cameras the same.

Example

use Libraries.Game.Game
use Libraries.Game.InputMonitor
use Libraries.Interface.Events.KeyboardEvent
use Libraries.Game.Graphics.Drawable

class Main is Game

    InputMonitor monitor
    KeyboardEvent keys

    action Main
        StartGame()
    end

    action CreateGame
        Drawable leftSquare
        leftSquare:LoadFilledRectangle(100, 100)
        leftSquare:SetPosition(0, 250)
        Add(leftSquare)

        Drawable rightSquare
        rightSquare:LoadFilledRectangle(100, 100)
        rightSquare:SetPosition(700, 250)
        Add(rightSquare)
    end

    action Update(number seconds)
        // Pressing the spacebar will set the game to use the desktop's resolution.
        // If the boolean is false, the cameras will not be adjusted to the new screen size,
        // making them appear to be zoomed in on the original area.
        // If the boolean is true (or omitted), the cameras will be adjusted to view the
        // new size of the screen. Drawables will remain at their original size and position.
        if monitor:IsKeyPressed(keys:SPACE)
            UseDesktopResolution(false)
        end
        // Using the desktop resolution will typically make the game go fullscreen.
        // To exit the game, the user can press the ESCAPE key.
        if monitor:IsKeyPressed(keys:ESCAPE)
            Exit()
        end
    end
end

UseDesktopResolution()

UseDesktopResolution will set the game to use the same display settings as the desktop's current screen resolution (independent of the game). This is only effective when used on desktop platforms - on other platforms, this will do nothing. Using this action will also adjust the size of the cameras on the default 2D and 3D layers to match the new screen size. To change the screen size without changing the cameras, use SetScreenResolution(ScreenResolution, false).

Example

use Libraries.Game.Game
use Libraries.Game.InputMonitor
use Libraries.Interface.Events.KeyboardEvent

class Main is Game

    InputMonitor monitor
    KeyboardEvent keys

    action CreateGame
        UseDesktopResolution()
    end

    action Update(number seconds)
        // Using the desktop resolution will typically make the game go fullscreen.
        // To exit the game, the user can press the ESCAPE key.
        if monitor:IsKeyPressed(keys:ESCAPE)
            Exit()
        end
