We now can add the drone to the project:
- Import the SimpleDrone package using Assets | Import Package | Custom Package.
- Drag the SimpleDrone prefab into the Hierarchy, and make it a child of ImageTarget.
- Select the drone and set the scene gizmo to Scale, or enter the Transform Scale to (0.1, 0.1, 0.0) and move it to resting on the card (Position Y = 0.06).
You should also add the animations to make the drone fly. We won't repeat the details here, please refer to the previous section.
