Question 1

A drone without a Rigidbody moves farther each second on a high-frame-rate computer. Its Update() method contains the line below. The float speed is intended to represent world units per second; Time.timeScale is 1, and nothing else moves the drone. Which replacement makes that interpretation of speed hold as the frame rate changes?

transform.position += Vector3.forward * speed;

Accepted Answer

transform.position += Vector3.forward * speed * Time.deltaTime;

Answer

transform.position += Vector3.forward * speed * Time.fixedDeltaTime;

Answer

transform.position += Vector3.forward * (speed / 60f);

Answer

transform.position += Vector3.forward * speed / Time.deltaTime;

Question 2

The edit history for a Guard prefab is:

Original asset: maxHealth = 100; detectionRadius = 10.
Commander instance: maxHealth overridden to 300; detectionRadius not overridden.
Revised asset: maxHealth = 120; detectionRadius = 15.

No script changes either field. After Unity propagates the asset revision, which values does the commander instance use?

Accepted Answer

maxHealth = 300; detectionRadius = 15.

Answer

maxHealth = 120; detectionRadius = 10.

Answer

maxHealth = 300; detectionRadius = 10.

Answer

maxHealth = 120; detectionRadius = 15.

Question 3

An Animator's Idle-to-Run transition has one condition: Speed > 0.1. Has Exit Time is enabled at 0.75, and the transition uses a fixed 0.2-second blend. The Animator window confirms that Speed rises above 0.1 promptly, but the transition waits for the Idle clip to reach its exit point. The designer wants the blend to begin as soon as the condition becomes true, without altering the clip or blend speed. What should change?

Accepted Answer

Clear Has Exit Time on the Idle-to-Run transition.

Answer

Set Transition Offset to 0.75.

Answer

Set Transition Duration to 0 seconds.

Answer

Increase the Idle state's playback speed.

Question 4

Keyboard Submit activates a uGUI menu's Play button, but pointer clicks do not. The failure began when a decorative sibling Image was added above the button. The Image overlaps it and has Raycast Target enabled. The EventSystem, input module, and Canvas GraphicRaycaster are functioning. The decoration must remain visible in front of the button. Select the repair that preserves both the artwork and pointer interaction.

Accepted Answer

Clear Raycast Target on the decorative Image.

Answer

Disable the Canvas GraphicRaycaster.

Answer

Clear Raycast Target on the button's Image.

Answer

Move the decoration behind the button.

Question 5

A passing hovercraft's engine rises in pitch as it approaches the listener and falls in pitch as it recedes. Its AudioSource Pitch remains 1, no script changes the audio settings, and Spatial Blend is 1. The sound director wants to remove this motion-related pitch shift while retaining positional panning and distance attenuation. Which AudioSource adjustment fits the request?

Accepted Answer

Set Doppler Level to 0.

Answer

Set Spatial Blend to 0.

Answer

Set Pitch to 0.5.

Answer

Set Min Distance to 20.

Question 6

An NPC's LOD Group selects detail solely from its relative screen height: LOD0 at 0.50 or above; LOD1 from 0.25 to below 0.50; LOD2 from 0.08 to below 0.25; culled below 0.08. With no cross-fading, the perspective camera widens its field of view without moving. The NPC's relative screen height drops from 0.42 to 0.18. What result should the artist expect?

Accepted Answer

LOD2 is selected, although the camera-to-NPC distance is unchanged.

Answer

LOD0 is selected to compensate for the smaller projected image with more geometry.

Answer

LOD1 remains selected because the camera has not moved farther away.

Answer

The NPC is culled because it has dropped below LOD1's lower threshold.

Question 7

A reproducible 3D physics test has this setup:

Sensor: enabled BoxCollider, Is Trigger enabled, OnTriggerEnter(Collider other) in its script.
Crate: enabled BoxCollider, Is Trigger disabled.
Both GameObjects are active. Neither object nor its parents have a Rigidbody; their layers interact.

The colliders remain overlapped for several physics steps without a trigger callback. The sensor must remain unaffected by gravity and collision forces. Which change supplies the missing requirement?

Accepted Answer

Add a kinematic Rigidbody to the sensor.

Answer

Make the crate collider a trigger too.

Answer

Move the Transform updates to FixedUpdate().

Answer

Use OnTriggerEnter(Collision other).

Question 8

An artist receives written permission to use specified released-game screenshots and an approved description of their contribution in a portfolio. The NDA still prohibits sharing unreleased assets and source files. A recruiter asks for a portfolio breakdown. Which response demonstrates the artist's work within the permission already granted?

Accepted Answer

Submit the authorized screenshots with the approved contribution description.

Answer

Send a password-protected video of unreleased scenes, with the studio credited throughout.

Answer

Provide source assets after removing the project name and other identifying labels.

Answer

Decline to provide any portfolio material until the remaining NDA restrictions expire.

Question 9

In Unity's Built-in Render Pipeline, a corridor's static surfaces receive baked indirect lighting, including diffuse color bleed from red walls. A moving character using the Standard Shader receives real-time direct light correctly but lacks that diffuse bounced light. The character must stay movable, and the team wants to reuse the baked lighting rather than calculate the bounce in real time. What should be introduced along its route?

Accepted Answer

A baked Light Probe network, with the character renderer set to sample it.

Answer

Higher-resolution lightmaps for the existing static corridor surfaces.

Answer

Reflection Probes that capture the corridor for the character material.

Answer

A baked lightmap for the character at its starting position.

Question 10

The art direction for a magical bridge calls for a continuous fade until the whole object, including reflective highlights, disappears. The bridge uses the Built-in Render Pipeline's Standard Shader. With Transparent mode selected, lowering Albedo alpha to zero leaves highlights visible. Which rendering mode matches the requested disappearance effect?

Accepted Answer

Fade

Answer

Opaque

Answer

Cutout

Answer

Transparent
