💡 Hint

Common Mistakes

Using 'Transform' instead of 'GameObject' to create a new object.

Trying to instantiate 'Component' directly.

In Unity, you create a new object by calling new GameObject().

💡 Hint

Common Mistakes

Using 'GetComponent' when trying to add a new component.

Trying to use 'RemoveComponent' which does not exist.

Use AddComponent<T>() to add a component like Rigidbody to a GameObject.

💡 Hint

Common Mistakes

Using uppercase 'Transform' which is a type, not a property.

Trying to call 'getTransform()' which does not exist.

The transform property is a shortcut to access the Transform component of a GameObject.

4fill in blank

Using different variable names for creation and adding component.

Using variable names not declared in the first line.

We create a GameObject named boxObject and then add a BoxCollider to it using the same variable.

5fill in blank

Fill all three blanks to create a GameObject, add a Light component, and set its color to white.

Unity

GameObject [1] = new GameObject("LightSource");

[2].color = Color.[3];

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