Unity Essentials: 2D Essentials Quiz

Create a top-down minigame similar to the 3D living room experience, but in 2D.

In this 2D Mission, you'll create a top-down 2D version of the interactive living room scene you created earlier. 

Just like in the 3D scene, you'll control a character, and try to collect all the objects in a room. By completing this scene, you'll learn how working in 2D is similar to working in 3D, but also how it’s different.

What happens when you turn on 2D mode in the Scene view? 

What happens when you turn on 2D mode in the Scene view?  Select the one correct answer.   

Turns off perspective and orients the camera to look towards positive Z, with the X-axis pointing right and the Y-axis pointing up.

Locks the Scene view camera to a fixed position, preventing any movement or rotation.

Enables the physics simulation to run in two dimensions, disabling the Z-axis.

Automatically converts all 3D models in the scene to 2D sprites.

"Automatically converts all 3D models in the scene to 2D sprites." — This statement is incorrect. The 2D mode affects the Scene view's camera perspective only and does not convert 3D models into 2D sprites.

"Locks the Scene view camera to a fixed position, preventing any movement or rotation." — This statement is incorrect. While the camera in 2D mode is optimized for 2D space navigation, users can still move and zoom within the Scene view.

"Enables the physics simulation to run in two dimensions, disabling the Z-axis." — This statement is incorrect. The physics simulation mode (2D or 3D) is determined by the components used (Rigidbody2D vs. Rigidbody) and is independent of the Scene view mode. 

Which of the following are actually built-in Unity components optimized for 2D development? 

Which of the following are actually built-in Unity components optimized for 2D development?  Select the two correct answers.   

"Square Renderer 2D" — This statement is incorrect. While Unity provides components for rendering 2D shapes, such as the Sprite Renderer, there is no specific "Square Renderer 2D" component. 2D shapes are typically handled by using sprites or meshes with appropriate materials.

"Layer Adjuster 2D" — This statement is incorrect. There is no built-in Unity component named "Layer Adjuster 2D." Layering in Unity is typically managed through camera settings, sorting layers, and the Z-position of objects for 2D games, or through the use of 3D components and positioning for 3D games.

Which of the following are true about the Rect tool in Unity? 

Which of the following are true about the Rect tool in Unity?  Select the two correct answers.   

The Rect tool can be activated using the T key as a shortcut in the Scene view.

It's designed for creating and editing physical materials for 2D objects.

It adjusts the transparency and color settings of UI elements.

It is used for manipulating the position and scale of 2D objects in the scene.

"It adjusts the transparency and color settings of UI elements." — This statement is incorrect. The Rect tool is focused on spatial manipulation (position, rotation, scale) rather than visual properties like transparency and color, which are adjusted in the Inspector window through component properties.

"It's designed for creating and editing physical materials for 2D objects." — This statement is incorrect. The Rect tool does not deal with materials or textures directly; it's used for spatial manipulation of objects in the scene, particularly UI elements and 2D sprites. 

What does the Order in Layer property do in the Sprite Renderer component? 

What does the Order in Layer property do in the Sprite Renderer component?  Select the one correct answer.   

Controls the level of detail that the sprite is rendered with, improving performance for distant objects.

Sets the physical layer the sprite belongs to for collision detection purposes.

Adjusts the sprite's color intensity based on its position in the scene. 

Determines the rendering order of sprites, allowing some to appear in front of or behind others. 

"Adjusts the sprite's color intensity based on its position in the scene." — This statement is incorrect. The Order in Layer property affects the sprite's rendering order, not its color intensity.

"Controls the level of detail that the sprite is rendered with, improving performance for distant objects." — This statement is incorrect. The Order in Layer property does not affect the level of detail or the performance optimization of sprites; it solely determines their rendering order.

"Sets the physical layer the sprite belongs to for collision detection purposes." — This statement is incorrect. The Order in Layer property is used for rendering order, not for setting physical layers for collision detection, which is managed by the Layer property in the GameObject's settings.

Which of the following is true about writing scripts for 2D GameObjects in Unity?

Which of the following is true about writing scripts for 2D GameObjects in Unity? Select the one correct answer.  

All scripting methods and components used for 3D GameObjects are incompatible with 2D GameObjects, requiring separate libraries. 

To work with 2D GameObjects in Unity, you must create a special kind of script asset from the Project window’s create menu named a “Script2D”, which is distinct from those used in 3D development.

Writing scripts for 2D GameObjects is largely the same as for 3D, but there are some methods optimized for 2D development, such as OnTriggerEnter2D instead of OnTriggerEnter. 

Unity will not allow you to apply a script that has references to 2D components or methods onto a 3D object. 

"To work with 2D GameObjects in Unity, you must create a special kind of script asset from the Project window’s create menu named a “Script2D”, which is distinct from those used in 3D development." — This statement is incorrect. Scripts in Unity can generally be used for both 2D and 3D development, with the main differences being in the specific components and methods used rather than the script's fundamental structure.

"Unity will not allow you to apply a script that has references to 2D components or methods onto a 3D object." — This statement is incorrect. Unity does allow the application of scripts referencing 2D components to 3D objects, though the 2D-specific components and methods may not function as intended on 3D objects without corresponding 2D components.

"All scripting methods and components used for 3D GameObjects are incompatible with 2D GameObjects, requiring separate libraries." — This statement is incorrect. Many scripting methods and components are compatible or have analogous versions across 2D and 3D development in Unity, allowing for a cohesive development experience without needing entirely separate libraries.
