How to assign Character Controller to NPC and Main Character

I have a fighting game which has NPC and Main Character

I added Character Controller to Main Character

But, I searched some articles which said they apply Character Controller to NPC as well.

But, the Character Controller has been grey and not able to apply to NPC.

I use iphone 1.7. How should I fix it?

Do you mean the menu item for the CharacterController component was greyed out? Try adding it again - you can add a CharacterController to as many objects as you like in the scene.

andeeee

Thanks a lot, I can add it now!!
