Select the GameObject in the Hierarchy or Scene view, click Add Component at the bottom of the Inspector, then search for the component by 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.

Guide manually when the task takes three clicks or fewer, such as adding one common component or tweaking a few fields. Automate with the REST component module when adding components to many objects or batch-configuring serialized fields.

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.

Unity warns about missing script references when other systems depend on the component being removed. Check dependent scripts and references before confirming removal through the gear menu's Remove Component option.
