Building the Colour shader of TPIM
The first step for the shader was identifying what RGB level worked the best for creating a colorful world into grey-scale, these are the colours that worked best for me are R = 0.3, G = 0.59, B = 0.11.
All other information will be handled by comments in the code.
Now that we have the Shader built we can write a C# script to have it around the player as seen below, the script would be attached to the player prefab
This sets it but it does not update it for that we need another script on the player
Then finally we want colour to seep into the world when a group of enimes is defeated so we use this script on a game object that tracks the enemies and the game object.
And there you have it. Now you just need to find interesting locations and to set up your nodes.
