Rigidbody 3D component in Unity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to add a Rigidbody component to the GameObject.

Unity

gameObject.AddComponent<[1]>();

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

BCollider

CTransform

DRigidbody

💡 Hint

Common Mistakes

Using Collider instead of Rigidbody.

Trying to add Transform component which already exists.

The Rigidbody component is added to enable physics on the GameObject.

2fill in blank

medium

Complete the code to set the Rigidbody's mass to 5.

Unity

Rigidbody rb = GetComponent<Rigidbody>();
rb.[1] = 5f;

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

Avelocity

Bmass

Cdrag

DangularVelocity

Attempts:

💡 Hint

Common Mistakes

Setting velocity instead of mass.

Using drag which affects air resistance.

The mass property sets how heavy the Rigidbody is.

3fill in blank

hard

Fix the error in the code to apply a force to the Rigidbody.

Unity

Rigidbody rb = GetComponent<Rigidbody>();
rb.AddForce([1]);

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

Anew Vector3(0, 10, 0)

BVector3.up * 10

Cnew Vector4(0, 10, 0, 0)

Dnew Vector2(0, 10)

Attempts:

3 left

💡 Hint

Common Mistakes

Using Vector2 which is 2D vector.

Using Vector4 which is not valid for AddForce.

The AddForce method requires a Vector3 for 3D forces.

4fill in blank

hard

Fill both blanks to create a Rigidbody and set it to use gravity.

Unity

Rigidbody rb = gameObject.AddComponent<[1]>();
rb.[2] = true;

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

ARigidbody

BCollider

CuseGravity

DisKinematic

Attempts:

💡 Hint

Common Mistakes

Using Collider instead of Rigidbody.

Setting isKinematic instead of useGravity.

First, add a Rigidbody component, then enable useGravity to let it fall.

5fill in blank

hard

Fill all three blanks to apply an upward force only if the Rigidbody's velocity is less than 5.

Unity

Rigidbody rb = GetComponent<[1]>();
if (rb.velocity.magnitude [2] 5) {
    rb.AddForce([3]);
}

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

ARigidbody

B<

CVector3.up * 10

DCollider

Attempts:

3 left

💡 Hint

Common Mistakes

Using Collider instead of Rigidbody.

Using '>' instead of '<' in the condition.

Adding force with wrong vector type.

Get the Rigidbody component, check if speed is less than 5, then add upward force.
