In the preceding function, we just use the GUI.BeginGroup() function to
draw the mask for the hit-point bar.
4. Now, we will go back to Unity and drag the HitPoint script to the UI game ob-

Hit Point UI (Script)

robotAI_C# (AI) or ro-
botAI_JS (AI)

Drag the robotAI_C# or robotAI_JS game object inside the Enemy game object
to the Hierarchy view
