Please Help

I don’t have the character controller or terrain assets! how do i get these?

just right click on Project Hierarchy and import package (Character controller).

Hii,

Goto "AssestsMenu"-> Click on "Import Package" -> Then click on "Character Controller"
Goto "AssestsMenu"-> Click on "Import Package" -> Then click on "Terrain Assests"

You will get all scripts and demo objects.
