Move the cube downward and to the right along the axis. Since the cube lives in 3D space, but can only be dragged in 2D each time, the axis on which you drag is especially important. You can move along the Z axis by selecting and dragging the cube by its red panel toward the blue line. In the Scene view, move the player object away from the enemy object along the Z axis using the mouse. We'll use this in the enemy script to help locate the player game object.
Tag the player object "Player" as well (see Tag drop-down control just under name field). This will be the enemy cube in our simple game.Īdd another Cube object to the scene using the same process as above, and name this one "Player". Make sure to press Enter to save the change. Rename the Cube object, which has the name "Cube" by default, to "Enemy". In addition, several components were attached to the Cube to provide needed functionality including mesh filter, box collider, and renderer. These properties are common to all GameObjects. Take a quick look at the properties of the new GameObject and see that it has a name, tag, layer, and transform. Add a new Cube object to the scene via the GameObject > 3D Object > Cube menu. The GameObject is central to development in Unity as almost everything derives from that type, including models, lights, particle systems, and so on. But always add and remove files via the Unity interface (or Visual Studio for Mac) and never through the file system directly.
This is always the top-level folder in the Unity Editor. It's empty now, but every single file you bring into your project goes here. The Assets folder contains all your assets-art, code, audio, etc. There's also a solution file that you can open in Visual Studio for Mac ( UnityLab.sln here).Ĭlose the Finder window and return to Unity. The Temp folder is used for temporary files from Mono and Unity during the build process. The ProjectSettings folder stores settings you can configure. The Library folder is the local cache for imported assets it holds all metadata for assets.
However, the only one that shows up in the interface is the Assets folder. Projects contain Assets, Library, ProjectSettings, and Temp folders as you can see. In the Project tab on the bottom, right-click the Assets folder and select Reveal in Finder. It's important to point out that projects in Unity are a little different from their Visual Studio for Mac counterparts. Use the Inspector to see that it includes common lighting properties including type, color, intensity, shadow type, and so on.

This provides light to the scene so that components like shaders know how to render objects. An Audio Listener component was also added by default, which essentially renders scene audio from a virtual microphone attached to the camera. Camera properties include transform information, background, projection type, field of view, and so on. Select the Inspector pane from the right side of the window to review its properties. Select the Main Camera object from the Hierarchy pane. These components are attached to a GameObject. A scene requires a camera for anything to be visible and an Audio Listener for anything to be audible. The new scene just has a camera and a directional light in it.
You can have as many scenes as desired in a project.

When you package your app for a platform, the resulting app will end up being a collection of one or more scenes, plus any platform-dependent code you add. A scene file is a single file that contains all sorts of metadata about the resources used in the project for the current scene and its properties. There's a lot more to it than that, but those are few of the more important components.įor developers new to Unity, everything that runs in your app will exist within the context of a scene. It has the scene hierarchy with game objects on the left, a 3D view of the blank scene shown in the middle, a project files pane on the bottom, and Inspector and Services on the right. You're now looking at the default Unity interface. Set the Project name to "UnityLab" and select 3D. This lab is intended for developers who are familiar with C#, although deep experience isn't required.
