Create floating text / damage popup text in Unity

Unity version: 5.3.5f

Create prefab of floating text

• Create new UI Text: Component - UI - Text, named PopupText
•  PopupText property
• Rect Transform: Anchor: Middle + center
• Set value of width and height
• Text: Alignment: middle and center
• Insert Outline component to make it better UI
• Add Animator controller component
• Make a great animation for the text (curve moving, etc.)
• Create new GameObject (child of Canvas), make it PopupText's parent, named PopupTextParent, make a prefab of it
• Move PopupTextParent to folder Resources/Prefabs (wherever location of the prefab, it should be in the Resource folder)

Code

•   FloatingTextController class
