====== Change the color of materials ======
This example VCI changes the color of a material when the grip button is pressed.
===== VCI script =====
function onUse(self)
print("onUse")
local r = math.random()
local g = math.random()
local b = math.random()
vci.assets._ALL_SetMaterialColorFromIndex(0, Color.__new(r,g,b))
end
math.random() is a pseudo-random number that returns a random value.\\
They randomly decide the value for red, blue and green to create a color.
===== About random =====
-- a = 0 ~ 1
a = math.random()
-- b = 1 ~ 100
b = math.random(100)
-- c = 1000 ~ 2000
c = math.random(1000, 2000)
When you specify no argument, it returns a value between or equal to 0 and 1.\\
When you specify one argument, it returns a value between or equal to 1 and the argument value.\\
When you specify two arguments, it returns a value between or equal to the first argument and the second argument.
