Pathfinding basics in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a variable for the target position.

Unity

public Vector3 [1];

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

AtargetPosition

BstartPosition

Cagent

Dspeed

💡 Hint

Common Mistakes

Using variable names unrelated to position like 'speed' or 'agent'.

The variable targetPosition is used to store the destination point for pathfinding.

Complete the code to get the NavMeshAgent component attached to the GameObject.

Unity

agent = GetComponent<[1]>();

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

BNavMeshAgent

CCollider

💡 Hint

Common Mistakes

Using Rigidbody or Collider which are unrelated to pathfinding.

The NavMeshAgent component controls the pathfinding and movement on the NavMesh.

Fix the error in setting the destination for the NavMeshAgent.

Unity

agent.[1](targetPosition);

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

ASetDestination

BGoTo

CMove

DNavigate

💡 Hint

Common Mistakes

Using non-existent methods like Move or GoTo.

The correct method to set the destination of a NavMeshAgent is SetDestination.

4fill in blank

hard

Fill both blanks to check if the agent has reached its destination.

Unity

if (agent.[1] <= agent.[2]) {
    Debug.Log("Destination reached");
}

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

AremainingDistance

BstoppingDistance

Cspeed

Dradius

💡 Hint

Common Mistakes

Using speed or radius instead of distance properties.

The remainingDistance property tells how far the agent is from the destination, and stoppingDistance is the distance at which the agent stops moving.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping waypoint names to their positions, filtering only waypoints within 10 units.

Unity

var waypoints = new Dictionary<string, Vector3>() {
    {"Start", [1],
    {"Middle", [2],
    {"End", [3]
};

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

Anew Vector3(0, 0, 0)

Bnew Vector3(5, 0, 5)

Cnew Vector3(10, 0, 10)

Dnew Vector3(15, 0, 15)

Attempts:

3 left

💡 Hint

Common Mistakes

Including points too far away like (15,0,15).

The waypoints are positions represented by Vector3. Only points within 10 units are included, so positions at (0,0,0), (5,0,5), and (10,0,10) are correct.
