NavMesh baking in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start baking the NavMesh in Unity.

Unity

NavMeshSurface surface = GetComponent<NavMeshSurface>();
surface.[1]();

Drag options to blanks, or click blank then click option'

ABuildNavMesh

BGenerateNavMesh

CStartBake

💡 Hint

Common Mistakes

Using BuildNavMesh() which does not exist on NavMeshSurface.

Trying to call GenerateNavMesh() which is not a valid method.

The Bake() method starts the NavMesh baking process on the NavMeshSurface component.

medium

Complete the code to assign the NavMeshSurface component before baking.

Unity

NavMeshSurface surface = [1]<NavMeshSurface>();
surface.Bake();

Drag options to blanks, or click blank then click option'

AGetComponent

BFindObjectOfType

CAddComponent

DGetNavMeshSurface

💡 Hint

Common Mistakes

Using FindObjectOfType which searches the whole scene instead of the current GameObject.

Using AddComponent which adds a new component instead of getting an existing one.

GetComponent() gets the NavMeshSurface component attached to the same GameObject.

3fill in blank

hard

Fix the error in the code to bake the NavMesh asynchronously.

Unity

NavMeshSurface surface = GetComponent<NavMeshSurface>();
var bakeOperation = surface.[1]();
await bakeOperation;

Drag options to blanks, or click blank then click option'

ABakeAsync

CStartBake

DBuildNavMesh

💡 Hint

Common Mistakes

Using Bake() which is synchronous and does not return an awaitable.

Using StartBake() which is not a valid method.

BakeAsync() starts baking the NavMesh asynchronously and returns an awaitable operation.

4fill in blank

hard

Fill both blanks to create a list of NavMesh build sources filtered by area type.

Unity

var sources = NavMeshBuilder.[1](transform, LayerMask.GetMask("Walkable"));
var filtered = sources.Where(s => s.area == [2]).ToList();

Drag options to blanks, or click blank then click option'

BCollectSources

💡 Hint

Common Mistakes

Using BuildSources or GatherSources which do not exist.

Using the wrong area number which filters out all sources.

CollectSources collects NavMesh build sources from the transform with the specified layer mask. Area 0 represents the 'Walkable' area.

5fill in blank

hard

Fill all three blanks to bake a NavMesh with custom build settings and sources.

Unity

NavMeshBuildSettings settings = NavMesh.GetSettingsByID([1]);
List<NavMeshBuildSource> sources = NavMeshBuilder.CollectSources(transform, LayerMask.GetMask("[2]"));
NavMeshData data = NavMeshBuilder.BuildNavMeshData(settings, sources, [3], transform.position, transform.rotation);
NavMesh.AddNavMeshData(data);

Drag options to blanks, or click blank then click option'

D0

💡 Hint

Common Mistakes

Using wrong settings ID which causes errors.

Using incorrect layer mask string.

Not defining bounds properly causing no NavMesh to bake.

Settings ID 0 is the default agent type. The layer mask 'Walkable' selects walkable surfaces. The bounds define the area for baking the NavMesh.
