💡 Hint

Common Mistakes

Setting orthographic to false keeps the camera in 3D mode.

Using null or 0 causes errors.

Setting Camera.main.orthographic to true switches the camera to 2D orthographic mode.

Complete the code to set the orthographic size of the camera to 5.

Camera.main.orthographicSize = [1];

💡 Hint

Common Mistakes

Using zero or negative values causes no visible view or errors.

Using too large values zooms out too much.

The orthographicSize controls the vertical size of the camera view in orthographic mode. Setting it to 5 is common for 2D setups.

Fix the error in the code to move the camera to position (0, 0, -10).

Unity

Camera.main.transform.position = new Vector3([1], 0, -10);

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

💡 Hint

Common Mistakes

Setting x to 10 moves the camera off-center.

Using -10 for x is incorrect here.

The camera's x position should be 0 to center it horizontally. The z position is already set to -10 to look at the scene.

hard

Fill both blanks to smoothly follow the player on the x and y axes.

Unity

Vector3 targetPosition = new Vector3(player.transform.position[1], player.transform.position[2], -10);

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

B.y

C.z

💡 Hint

Common Mistakes

Using .z would follow depth, which is not needed in 2D.

Using .position twice is incorrect syntax.

To follow the player horizontally and vertically, use .x and .y to get the player's position on those axes.

hard

Fill all three blanks to clamp the camera's x and y position within limits and keep z at -10.

Unity

float clampedX = Mathf.Clamp(player.transform.position[1], [2], [3]);
float clampedY = Mathf.Clamp(player.transform.position.y, -5, 5);
Camera.main.transform.position = new Vector3(clampedX, clampedY, -10);

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

D.y

💡 Hint

Common Mistakes

Using .y instead of .x for clamping x position.

Swapping min and max values in clamp.

Not clamping the x position at all.

Clamp the player's x position between -3 and 3 using Mathf.Clamp and access the x coordinate with .x. The y position is clamped separately.
