Usage: |
-- Corona Game SDK example of how to let two bodies circle each other by applying a continuous, attracting force | |
-- | |
-- The example uses the physics engine, sets gravity to 0, creates two balls separated in the x-direction, | |
-- with initial speeds in opposite y-direction. | |
-- Thru an enterFrame event handler, an attracting force is continuously applied to both balls with body:applyForce(). | |
-- The force is normalized over the distance between the two balls. | |
-- By playing with the initial speed and force factors, you can make the balls spin faster/slower in circles or ellipses | |
-- | |
-- Save this file as "main.lua" in a project directory and load it in the simulator | |
-- |
-- Color to RGB value table for Lua coding with Corona | |
-- Color values copied from "http://www.w3.org/TR/SVG/types.html#ColorKeywords" | |
-- | |
-- Usage for Corona toolkit: | |
-- add this file "colors-rgb.lua" to your working directory | |
-- add following directive to any file that will use the colors by name: | |
-- require "colors-rgb" | |
-- | |
-- If you need the RGB values for a function list, you can use "colorsRGB.RGB()", like | |
-- colorsRGB.RGB("chocolate"), which returns the multi value list "210 105 30" |
