Line 29.
The
Mathf.Clamp
utility function is used while constructing an ammo
string for the active weapon.
Clamp
ensures a numerical argument is always
within a specified minimum and maximum range, rounding the value to the
nearest number at the minimum or maximum extreme, if required.
Add the
GUIUpdateStats
class to the root GUI object in the scene, and then use the Object Inspector
to specify the two label controls for the text data. To do this, simply drag and drop the existing
GUILabel components in the Objector Inspector into the GUILabel fields of the GUIUpdateStats
component (see Figure
8-15
).
