All,
I am struggling a bit with functions. I have an object in my program that I am trying to provide feedback to my main program through. The program is such:
I have a man figure wich the user can move the arms up or down, and I wan to get the shape based on that position so I can properly add the man to the physics engine. My code for the man is in a seperate file titles BlockMan.lua. If I want to add a function that detects the position of the arm and and returns the appropriate body points, how do I define it and then allow access form my main program?
My BlockMan.lua file is here:
[code]-- This module is designed to provide a block man and associated functions to
– the main.lua program.
module(…, package.seeall)
function newMan()
local man = display.newGroup()
– Set rgb color scale for man.
local r = math.random(0,255)
local g = math.random(0,255)
local b = math.random(0,255)
– Build Body Parts.
local body = display.newRect(-26,30, 52,52)
body:setFillColor(r,g,b,255)
local head = display.newRect(-13,4, 26,26)
head:setFillColor(r,g,b,255)
local rightArm = display.newRect(-78,30, 52,13)
rightArm:setFillColor(r,g,b,255)
local leftArm = display.newRect(26,30, 52,13)
leftArm:setFillColor(r,g,b,255)
local leftLeg = display.newRect(13,82, 13,52)
leftLeg:setFillColor(r,g,b,255)
local rightLeg = display.newRect(-26,82, 13,52)
rightLeg:setFillColor(r,g,b,255)
local rightHand = display.newRect(-78,20, 5,10)
rightHand:setFillColor(r,g,b,255)
local leftHand = display.newRect(73,20, 5,10)
leftHand:setFillColor(r,g,b,255)
local rightFoot = display.newRect(-36,129, 10,5)
rightFoot:setFillColor(r,g,b,255)
local leftFoot = display.newRect(26,129, 10,5)
leftFoot:setFillColor(r,g,b,255)

Thanks for the help…
