    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

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

The Remove action will remove an item that was put into the game using the Add action. More specifically, the item will be removed from the current default Layer2D. The game will no longer handle removed items - for example, removing a Drawable will make the game engine stop drawing it.

Parameters

Example

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

class Main is Game
    Drawable bunny

    action Main
        StartGame()
    end

        bunny:Load("Images/Rabbit.png")
        Add(bunny)

        // If we don't have this remove command, the bunny will draw.
        Remove(bunny)
    end
end

RemoveAmbientLight()

This action will remove the ambient lighting from the currently active Layer3D.

Parameters

  • text value: this action set text to the system clipboard.

Example

use Libraries.Game.Game

class Main is Game
    action Main

SetColliding(boolean collide)

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

Parameters

  • boolean collide

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.

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

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 Main
        StartGame()
    end

    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
    end
end
