Bases de Gluon

Les jeux créés avec «GluonEngine» sont tous construits de la même manière. Ce chapitre décrit brièvement comment cela fonctionne. Si vous ne comprenez pas encore comment fonctionnent les systèmes basés sur le paradigme GameObject / Component, c'est ici que vous devriez commencer.

Introducing Creator

Once you understand the basic layout of a game built with GluonEngine, you are ready to look at Gluon Creator, the tool with which you build the games. This chapter describes the user interface and the workflows of the tool.

Création de jeux

Une fois que vous avez lu les deux premiers chapitres et que vous vous sentez prêt à commencer à créer des jeux avec Gluon, allez-y et faites-le. Si vous êtes bloqué à un moment donné et avez besoin d'une aide supplémentaire avec des détails, c'est là que vous devriez regarder.

Bases de Gluon

Les jeux créés à l'aide du moteur de jeu Gluon, GluonEngine, sont appelés «GameProjects». Ils se composent de différents types d'objets travaillant ensemble pour créer un jeu. Ce qui suit est une brève introduction au fonctionnement de la structure d'un GameProject. Vous pouvez commencer à travailler avec Gluon Creator sans l'avoir lue, mais cela vous facilitera la vie si vous comprenez ces termes de base, car ils sont utilisés dans le reste de la documentation.

The GameObject Hierarchy

At the top of the Gluon GameObject Hierarchy is the GameProject, which is basically your entire game. A GameProject contains one or more Scenes, which can be anything from a level map or a menu screen. A Scene is composed of one or more GameObjects. A GameObject is a tree of GameObjects or any number of Components. A GameObject represents a functional unit in a scene, like a Car object, which can also be made up of other parts which are GameObjects in themselves (like a rocket backpack or a weapon). Components provide the logic that operates on the GameObject they are attached to. Components can be attached to any number of Assets. Assets simply represent a piece of data stored on disk, like a sound file or an image file.

The GameObject hierachy is made up of instances of GluonEngine::GameObject in a tree structure with a parent-child system, each with any number of GluonEngine::Component instances. The Components provide most of the logic in the game, and since so many are usable in so many places, Gluon would ship with a number of pre-created Components (such as a Camera, Input handlers, MeshRenderer, TextureRenderer and so on).

The logic behind creating this system is to enable the game programmer to enforce encapsulation and create reusable components, which can then be applied to numerous GameObjects. It also allows for sane separation of the different types of logic required for each part of a GameObject, thus potentially creating cleaner, more readable code. At the same time, the structure described here would allow for the creation of a graphical tool to manage all of the components' settings. Components are implemented as plugins, making the code even more flexible and separated.

More on Components

Components are like properties that you can attach to GameObjects, such as a "render" Component that actually makes the GameObject visible, or a "SoundListener" Component that gives the object the ability to listen to sounds. Components can also be scripts that controls the behaviour of the GameObjects attached to them. All GameObjects in Gluon have their Transform properties built-in, giving the object its position, rotation, and scale (it doesn't make much sense to have an object that doesn't have at least a position). Components do not have Transform properties, but the GameObject to which a Component is attached to does.

Introducing Creator


In the image to the right you can see Gluon Creator in its default layout, with the Invaders sample loaded. In a rough clock-wise order, the elements of the window are:


This shows all the Assets that you have in your project, such as sounds, textures, scripts and Scenes.


This is a list of the pre-defined functionality available to you in Gluon Creator. The Components are things like sound emitters and listeners, camera controllers, input handlers and the like.


This is the view of your current Scene from the perspective of the camera.


The contents of the current Scene - in essence your scene graph.


The place where you can see and manipulate every option on the various Components which are attached to the GameObjects in your game.


This is where debugging messages, errors from scripts and other information from the various Components are shown.

Workflow in Gluon Creator

The work flow of using Gluon Creator to create games is based around the idea that you should be able to use your mouse for as much of the work as possible. As such, adding an Asset to your project is a task done by dragging a file into the Project pane from your file browser (or alternatively by clicking the "Add Asset..." button in the toolbar). It will then be copied to the project folder, and be made available for use in your game.

To describe a scene in a game, you select the appropriate Scene in the Project view, which causes it to be loaded and shown in the Scene pane, and in the View the camera view will show what the camera sees in the newly loaded scene. You can now edit this scene, by adding and removing GameObject to the Scene, and by adding Components to those GameObjects.

To add a GameObject to the scene, click on the "Add GameObject" button on the toolbar. This will add a new, empty GameObject to the Scene, and if you have an existing GameObject selected, the new one will be added as a child to the selected one. This allows you, as described in Gluon Basics, to build items for the game based on multiple GameObjects in a hierarchy, which all move along with each other.

So that you can change the values for the various Components, selecting a GameObject in the Scene view will make the properties for that object and all the Components on it show up in the Properties view, which is a scrollable, categorized list of all the various properties.

One of the functions which will be performed with some regularity from the Properties view is that of setting references to various Assets, for example setting the texture of a SpriteRenderer, or the sound of a SoundEmitter. This is done by clicking on the "..." button in the Properties view and selecting the appropriate item from the list.
