// These tell the game how many points/stops there are in the gradient. (Much like Photoshop gradients where you can set a color at each point)

Player:SetNumPathGradientPoints(column,amount)
Player:SetNumArrowGradientPoints(column,amount)
Player:SetNumStealthGradientPoints(column,amount)

// These position those points on the column provided. (1 = 1 arrow -or- 64 pixels)

Player:SetPathGradientPoint(point,column,where)
Player:SetArrowGradientPoint(point,column,where)
Player:SetStealthGradientPoint(point,column,where)

// Exmaple:
//
//	P1:SetArrowGradientPoint(0,0,1)
//	
//	This would set the first point in the gradient 1 arrow (64 pixels) down from the receptors on column 0, which is the left column, on Player 1
//	Keep in mind that column and point numbers start at 0 and not 1. (I'm looking at you, Lua.)

// These will set the color of the point provided.

Player:SetPathGradientColor(point,column,r,g,b,a)
Player:SetArrowGradientColor(point,column,r,g,b,a)
Player:SetStealthGradientColor(point,column,r,g,b,a)

//	Example:
//
//	P1:SetArrowGradientColor(0,2,1,0,0,1)
//	P1:SetArrowGradientColor(1,2,0,1,0,1)
//	P1:SetArrowGradientColor(2,2,0,0,1,1)
//	P1:SetArrowGradientColor(3,2,1,1,1,0)
//
//	This arrow gradient has 4 points in it starting from 0. Point 0 will be colored Red, then point 1 will be colored Green, then point 2 will 
// 	be colored Blue, and the final point will be a fade on the alpha channel

//	To put it all together, here is some example code...

		for pn = 1,2 do -- first, we run a loop so we can grab players 1 and 2
			local a = Plr(pn) -- grab the players here with this function (a means both players in this context)
			if a then -- if they exist do a thing
				for col = 0,3 do -- iterate through all the columns
					a:SetNumArrowGradientPoints(col,4)	-- for each column, set the number of points to 4

					a:SetArrowGradientPoint(0,col,1) -- set their points
					a:SetArrowGradientPoint(1,col,2)
					a:SetArrowGradientPoint(2,col,3)
					a:SetArrowGradientPoint(3,col,4)

					a:SetArrowGradientColor(0,col,1,0,0,1)	-- set their colors and shiet
					a:SetArrowGradientColor(1,col,0,1,0,1)
					a:SetArrowGradientColor(2,col,0,0,1,1)
					a:SetArrowGradientColor(3,col,1,1,1,0)
				end

// You can swap out "Arrow" with "Path" so it affects the arrowpaths or "Stealth" so it only affects the notes when
// stealth is applied

// And there you go! You can now gradient!
