### 2.1 How do I make a serious game?
Just go to www.celestory.io and create an account to start creating a serious game in minutes, starting from a new project or an example to customize.
### 2.2 What tools to use to create serious games?
There are two types of tools to create serious games: classic video game engines (Unity, Unreal Engine...) which require specialized developers, and no-code tools accessible without technical knowledge, such as Celestory, which allow you to visually build the game scenario, without writing a single line of computer code.
### 2.3 Is it necessary to have programming skills to use Celestory?
No mastery of computer languages is necessary because the creation is based on content that everyone can produce without programming with code (text, visuals, choices, indications...).
### 2.4 What types of content and resources can I integrate into Celestory?
In Celestory, you have an online storage service for image, sound, and video files. You can directly integrate all your textual content in many forms (dialogues, notifications, choices...) while associating it with files (characters, sets, objects...).
It is also possible to import content from the web in real time (image address, YouTube video, website...) or from your software (emails, spreadsheets, drive, CRM...).
### 2.5 Where can I find resources to help me create my serious game?
You can consult the Celestory documentation, watch the creation examples, access the support chat, and even from the tool when you are in the middle of creation. If the chat does not load, you can access it at this address. You can also contact us for support or personalized training at contact@celestory.io.
### 2.6 How to choose and define your serious game to create your online training?
A serious game must first be defined according to your priorities: it is a balance between staging (text, then image and video) or richer and more personalized content (more branches, more advanced indications with AI...).
You can save a lot of time by starting from an example format to customize directly.
### 2.7 How to ensure the engagement of players and learners in a serious game?
Engagement — the ability to stay and return to the experience — will be maximized with a personalized experience and attractive content. Give the game a memory of the players' actions using variables, which you can then save locally via the checkpoint blocks or in the cloud via a database like Airtable (or Google Sheet, Microsoft Excel...).
### 2.8 How long does it take to create a serious game with Celestory?
You can create a prototype of a serious game in a few minutes, then improve its personalized content and staging ambition in a few hours.
### 2.9 How do I integrate AI into my creations?
AI can be integrated at several levels in Celestory. There are AI creations (text, image, sound, video) that can be integrated into your dedicated hosting, or generated in real time at the player's request (text, voice, image), for example to make NPCs (non-player characters) talk endlessly. Watch the Celestory AI tutorials for Replies/Choices, NPC Audio, or AI World Scenery.
### 2.10 What style can we do? 2D, 3D, more realistic, comics?
Celestory supports all 2D content because it is easy to design and modify, manually or using generative AI. 3D video game content is not supported because it does not work in a simple browser, requires a lot of computing power, a whole creative team, and requires being a specialized developer in a video game engine.
The available game formats are very diverse: chatbot, visual novel (interactive comics), clickable areas, virtual tours, escape games, interactive films, quizzes, cards, memory games...
All kinds of content are then adaptable: educational, police, fantasy, romance, science fiction...
### 2.11 Can we do VR?
Yes, VR systems now accept PWA (progressive web apps) in 2D floating in the virtual world, including augmented reality.
### 2.12 What support do you offer to create our serious game?
You can contact us via the following links for tailor-made training and co-creation with the help of experts recognized in serious games and AI content creation.
### 2.13 Is Celestory based on an open-source project?
No, Celestory is proprietary software. The sources of the games created in HTML5 are transparent.
### 2.14 Do I need an internet connection to run Celestory?
For creation yes, not necessarily for the user of the games.
### 2.15 How can I save my project?
Just click regularly on the save button or use the shortcut Control+S (PC) or Cmd+S (Mac). Saving is not automatic to avoid save conflicts between multiple creators who want to explore different versions of the project.
### 2.16 Can I save my files locally?
Yes, it is possible to export Celestory project modules offline and merge or re-import them.
### 2.17 What is the maximum size of a project?
A project has no graph size limit. The limits of AI usage and online file storage depend on your subscription.
### 2.18 Is there already a content bank that I can use?
Yes, you can use +1500 content items (characters, sets, music) present in the example projects.
### 2.19 How do I add content?
Just open the blue main menu of your project and select the Files option. You can then create folders and upload your content (image, video, sound).
### 2.20 What are the best audio, image and video file formats to use?
Supported formats are: PNG, JPEG, GIF, MP3, MP4.
### 2.21 Is there a size/weight limit to the content I can import?
There is no strict file weight limit. However, be careful not to upload files that are too heavy, as your user will have to pre-load them for the experience to launch correctly — this will depend on their internet connection.
### 2.22 Where can I find illustrations, content for my game?
You can find illustrations of characters, sets and objects in the examples, as well as create them via generative AI tools such as Dall-E 3, Leonardo or Midjourney.
If you want advanced artistic direction and personalized artistic support, you can call on our experts (illustrators, videographers, sound engineers...).
### 2.23 Are there any templates/models? How do I import a template or an existing project?
There is a page of examples that you can easily copy. Once copied, you can modify them. If you want to import them into an existing project, just export and import the modules.
### 2.24 Where are there game examples?
Yes, there are examples of graphs of games to understand their design, but also many demos of public games.
### 2.25 Are there any tutorials?
Yes, in the page of example projects of games, the Step by Step section allows you to understand the different concepts of Celestory as you go through the projects. The first tutorials allow you to be autonomous in a few hours.
### 2.26 Can I add difficulty levels to my game?
The difficulty of your game depends on its design. Use skills such as logic, memory, checkpoints or even speed of action with Quick Time Events to adjust the difficulty.
### 2.27 Can I preview and test my game?
You can and should test your game very often using the "Play Current Module" button. You can test your game from any part of the tree structure. Finally, you can make private publications of the game for your beta testers and collect their feedback before distributing it more widely.
### 2.28 What is a variable?
A variable is an element that changes value. It has an initial value (at the launch of the experience) and can change in a declarative way (e.g.: I choose the first name of my character), behavioral (e.g.: Make a choice option that removes any going back), automatic (e.g.: number of actions remaining in an escape game) or contextual (e.g.: when an email is received, when another user changes an element).
There are different types of variables: true/false (Boolean), numerical (e.g.: X=12), textual (e.g.: Email), lists (e.g.: objects in an inventory) or Object (a JSON-like key/value structure, e.g.: a complete player record with name, score and inventory in a single variable).
### 2.29 I have a game idea, but I don't know where to start. How can Celestory help me structure my project?
Start by looking at the page of examples of projects. Start by creating your project in Chatbot format in text version. Think of a first part of your scenario to create a few different endings that will allow you to differentiate users. Then build a simple scenario and distribute it to your test users. Improve it with their feedback.
Think about the minimum content format needed to achieve a first digital experience with a first measurable objective. What information should be recorded for each user between sessions? This information will be translated into variables.
### 2.30 Can I access or modify the source code of my game?
Yes, once your HTML5 game is exported, you can modify it by coding. However, it will always be faster to go through Celestory's no-code interface.
### 2.31 Can I add some code to my games?
Yes, you can import your own Javascript and CSS code into your game. In particular through the Javascript and CSS blocks and the CSS option in the menu items (custom CSS).
