fadebetweencolours-gml

• A script for .gml, YoYo Games' proprietary language which forms part of their Gamemaker: Studio software.
• Use this script to fade between two RGB colours at a certain rate every game step.
• The rate refers to how much the RGB values (ranging from 0-255) change each step. A rate of 5 would change the R, G and B values of the original colour by 5 each step until it reached the R, G and B values of the target colour.
