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 top menu path 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 the whole component.

Use the manual Inspector workflow when the task takes three clicks or fewer, such as adding one common component or tweaking a few fields. Switch to REST automation when adding components to many objects or batch-configuring serialized properties.

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 line marks the drop position.

The Inspector shows a human-readable label rather than the exact serialized property name. Hover over a field label to see its tooltip, and use reflection-based automation when you need the precise property name.
