Now let's add vertical camera panning using the same camera box technique.

Vertical Panning Methods

Create two new methods for vertical panning:

• shouldPanCameraDown() — When camera box top reaches screen top

• shouldPanCameraUp() — When camera box bottom reaches screen bottom

Panning Down (Player Jumping)

When the player jumps and the camera box reaches the top of the screen:

if (cameraBox.position.y <= 0) {   camera.position.y -= player.velocity.y }

This reveals more of the level above.

Panning Up (Player Falling)

When the player falls and the camera box reaches the bottom:

if (cameraBox.position.y + cameraBox.height >= canvas.height) {   camera.position.y -= player.velocity.y }

The vertical camera follows the same principles as horizontal — we're just checking different edges and modifying camera.position.y instead of x.

With both horizontal and vertical panning, your camera now follows the player throughout the entire level.
