#namespace colors;

/*
	Color coded AI travel system
	A colorCode is a color( red, blue, yellow, cyan, green, purple or orange ) and a #.
	When a trigger and AI and node are color grouped in Radiant, they get a unique color and #.
	When when a color coded trigger is hit, that colorCode is "fired" and any AI that are in colorCoded mode get their goalnode set.

	AI can be forced to a color generically. For example if an AI is forced to the color "red" and a trigger fires off "red15", the AI
	will go to that node even if the AI doesn't have script_color_allies( or axis ) "red15". This is mainly for friendlies.
	
	AI can also have their script_careful variable set, which prevents them from advancing to a node or a volume if an enemy is occupying it.
	They will move up if the zone is cleared.
	
	Volumes can also be tagged with a code and a number like r6. So if an enemy is present in this volume, no AI will run to any node tagged r6.
