Select the GameObject in the Hierarchy or Scene view, click Add Component at the bottom of the Inspector, then search for the component name or browse the category list. You can also use the Component menu, such as Component > Physics > Rigidbody.

Click the gear icon on the source component header and choose Copy Component. Then select the target GameObject, open the gear menu on the matching component, and choose Paste Component Values, or Paste Component As New to add it entirely.

Manual steps are best when the task takes three clicks or fewer, like adding one component or tweaking a few fields. Automate with the REST component module when adding components to many objects, batch-configuring serialized fields, or toggling many components at once.

No, the Transform component is always first and cannot be moved. Other components can be reordered by dragging their grey header bars in the Inspector until a blue drop line appears.

The Inspector shows a human-readable label rather than the exact serialized property name used in scripts. Hover over a field label to see its tooltip, and use reflection or the REST module when you need exact property names for automation.
