Create your first application
This tutorial will teach you the basics to navigate through the Valkyrie Engine screens and create your very first app.
Start the Valkyrie Launcher and you will get three tabs:
- My Profile: enter your username and token, this step is necessary for you to export your projects. Free users also need to create an account and enter the token present in their profile.
- My Apps: the apps you have been working on will be displayed there.
- New App: these are shortcut templates for you to select in order to create a new app. You can reconfigure the content at your will once opened.
Firstly, start with selecting the New App tab.
You will be prompted to select a template to create a new application.
To better understand the interactions in Valkyrie, we recommend that for your first trial you select an Orbit Camera template. Once selected, a Create App screen pops up.
Select a Name for your application.
The directory containing the template you selected is indicated in the Base App field.
Choose the directory where you want to save your app in the Location field & proceed by clicking on Create. The application will be created and saved in your documents.
Note that by default, applications are located in C:/User/USER_NAME/Documents/VlkApps/ on Windows and /Users/USER_NAME/VlkApps on macOS.
You are now in the Valkyrie workplace. Note that for system performance purpose, the levels are not automatically loaded and the initial screen initially displays a cube.
From there, you need to drag & drop your project level from the bottom left area on the viewport or the timeline, and confirm that you want to set the level ‘Orbit Camera’ in order to load your application.
Behold, you now have a beautiful sphere before you. With this template, you have successfully created your first app!
Before we start, it is important to understand that you are already in your application. What you see is what you get regardless of the platform you intend to deploy on (Windows, MacOS, IOS…).
Orbit Camera is one of the most basic setup you can create: a sphere, a light and a camera. What this app does, is that when you move the camera with the mouse it orbits around the sphere. Simple.
Whatever the changes you do later on, remember to save your level after each iteration.
If you close Valkyrie, you can open your app by selecting it in the launcher, or by double-clicking on the Valkyrie (.vlk) file in your application directory.
Now you might be wondering what you will be able to do, so let us dive into the specificities of the Valkyrie Engine from this point.
Start by getting to know the function of each panel detailed below.
For instant help, hover your mouse over a menu, button or object while pressing CTRL, a contextual window will appear featuring the description of the item.
The viewport allows you to visualize all aspects of your scene.
Making a Right Click on Final at the Top-Left Corner of the Viewport allows you to visualize each channel individually.
- The library contains all the imported & built-in assets you can use in your scene.
- Object Configuration (Inspector):
- All scene objects can be configured when selected. The object configuration allows you to configure all attributes of the selected item.
- Scene Assets:
- Scene assets displays all the assets, actions & entities present in the scene.
- The timeline allows you to visualise which assets, actions & entities are active in the timeline.
- Each layer, asset can have an independent timeline depending on the interactions you wish to create.
- Note that you can add up to 5 timelines in the workplace.
- Material Editor:
- When an asset is selected, its material properties will be displayed in the material editor.
- You can customize the materials there to match the output you’re looking for.
- The console logs all actions performed in the scene and brings potential errors to your attention.
The Library menu allows you to import assets inside your application and it is split into 7 tabs:
- Your project will be saved as a Level and displayed in this tab. If your scenes are complex, you can split them into different levels and call them individually via a master level.
- We recommend in addition that you save your work in progress incrementally under new levels so that you can go back to a previous iteration if anything goes wrong.
- Modifying attributes in a later iteration does not affect previous iterations.
- All iterations / levels will be displayed in this tab.
- The Entities tab is used to create built-in assets such as:
- Character Nodes
- Data Tables
- Post Effects
- Particle Systems
- This tab contains a list of Actions that allow you to create interactions of various complexities. It features a visual logic engine that will empower you to create anything your mind can think of without writing a single line of code.
- Events are a set of conditions that allow you to define when Actions are triggered. For example, to start an animation if the user presses a certain UI element, or to trigger an animation when a character collides with an asset. Your imagination is the limit!
- The Data tab contains all of the imported assets. To import an element, simply copy it in the C:\Users\USER_NAME\Documents\VlkApps\Your-Project\data folder. You can create subfolders, however to avoid missing textures when exporting, all assets must be contained within the data folder.
f) Application Template Folder
- Displays the templates contained in your project.
- Refreshes the data folder for newly added and overwritten files.
