DelayedMessage

Author: Hayden Scott-Baron (Dock)

Description

A simple script to call a message on an object after a while.

Usage

Place this script on the gameobject you wish to have call a function later on. Useful for Destroying an old object, for example, or for allowing objects to repeatedly fade in/out using the FadeObjectInOut script.

Technical Discussion

Set the initial time to negative to reduce the initial wait.

	This uses 'SendMessage' on an object after a delay. 
 	You can send a value such as a string, int or float
 	You may also set this to repeat a message on an object.
