Test your understanding of Unity’s Physics, Movement, and MonoBehaviour with this insightful beginner-friendly quiz!

RagdollController

NavMeshAgent

CinemachineBrain

PathfindingModule

Which specialized Unity component handles AI pathfinding and local avoidance on a baked NavMesh?

Increase fixedDeltaTime

Multiply diagonal input by 2

Normalize the input vector before applying speed

Switch to 3D physics

A top-down 2D game moves characters by applying raw directional input. Diagonal movement ends up faster than straight movement. How can you fix the discrepancy so all directions share a uniform speed?

Modify the terrain resolution

Use OnCollisionEnter in a MonoBehaviour

Place NavMeshObstacles that carve or update the path

Switch the agent to Kinematic mode

An AI character using NavMeshAgent navigates large obstacles but can pass through newly spawned small obstacles not present at bake time. How can you prevent the agent from ignoring these dynamic obstacles?

Disable the Animator during jumps

Blend with a Timeline track

Use a hybrid approach that toggles or layers root motion only for specific states

Always override root motion via script

You want partial root motion for walk/run animations but code-driven movement for jumps and dashes. How can both systems coexist so they don’t conflict and the final motion remains coherent?

Blend or lerp speed factors over time when terrain changes

Use OnTriggerEnter to instantly set the new speed

Ensure maximum friction by default

Bake separate NavMeshes for each terrain type

Your open-world terrain uses different ground types (normal, mud, ice), each needing unique speed modifiers. How can you implement seamless transitions between these speeds so movement doesn’t abruptly jerk or stutter?

Discrete

Continuous Dynamic

Kinematic

Raycast-Only

Which collision detection mode in Unity’s 3D physics helps prevent tunneling for very fast objects?

Solver Iterations

Default Bounce Threshold

Min Penetration For Penalty

Default Depenetration Velocity

Which setting in the Physics Manager influences how deeply colliders can penetrate before a collision is solved, helping reduce interpenetration?

Changing Time.timeScale to 2.0

Increasing solver iteration count or tuning joint drive settings

Converting the ragdoll to a NavMeshAgent

Disabling collisions entirely

A complex ragdoll collapses awkwardly with jittery limbs. Which adjustment often helps stabilize ragdoll joints?

Rely entirely on the server for immediate movement

Use client-side prediction and reconciliation for physics states

Disable physics on clients and show placeholders

Use an enormous fixed time step on the server

In a networked game, physics objects must stay synchronized across clients while local interactions remain smooth. How can you balance local responsiveness with authoritative server updates?

Use unscaledDeltaTime for all physics calculations

Integrate partial kinematic control, stable solver settings, and smooth clamp on extreme forces

Limit all object mass to 1.0

Destroy and respawn objects whenever they move unexpectedly

A VR title needs realistic object handling under varying mass, friction, and center of mass shifts. How do you keep the experience immersive without objects flying erratically when force is applied?

RequireComponent

ExecuteInEditMode / ExecuteAlways

HideInInspector

EditorBrowsable

Which attribute allows a MonoBehaviour script to run code in the Editor, even when not in Play Mode?

Reset()

Awake()

OnValidate()

OnDrawGizmos()

Which function is automatically invoked whenever a serialized field is changed in the Inspector, enabling you to validate or clamp the new value?

Use Update() with a yield return null

Place [DefaultExecutionOrder(-100)] on the class

Delete all other scripts except the manager

Force a WaitForSeconds in every other script

A data-manager MonoBehaviour must be ready before other scene scripts access it, but you don’t want to modify global script execution order. How can you ensure it initializes first?
