Figure 4-9. Enabling BoxCollider visibility in the Scene viewport. If disabled, no colliders will be visible
After Collider visibility is enabled, add a new BoxCollider component to the power-up object in the
scene. To do that, select the power-up object, and choose Component ➤ Physics ➤ Box Collider
from the main application menu. Once added, use the collider Size property, in the Object Inspector,
to size the collider, surrounding the power-up and leaving some margin of space around the fringes.
Be careful to give the collider some depth, too, even though the power-up object is really a flat
sprite. It'll need depth for collisions to work properly (see Figure 4-10 ).
