Smooth Camera

Smooth Camera
Version 1.02
SomeRanDev

This plugin requires the Camera Core plugin:
http://sumrndm.site/camera-core/

This plugin gives the camera of your game smoother motion during gameplay 
and specific camera motions.

==============================================================================
Plugin Commands
==============================================================================

The following plugin command can be used to change the "Delay Power" of the
camera:

SetDelayPower [value]

Set "value" to a number (preferably around 1 to 10) to customize the delay
of the camera.
