-- Code 12d - tween path

-- April 2013

-- Accepts a table of waypoints to follow

-- Setup multiple destinations or stop points
-- strt is the starting point
-- t1 - t5 are waypoints for the path
-- Then you will find four tweens - only one
-- at a time should be uncommented. The last tween
-- takes two lines so comment or uncomment carefully

-- Use this function to perform your initial setup
function setup()
    strt = {x = WIDTH, y = HEIGHT, size = 20}

    t1 = {x = 102, y = 100, size = 10}
    t2 = {x = 200, y = 500, size = 50}
    t3 = {x = WIDTH/2, y = HEIGHT/2, size = 100}
    t4 = {x = WIDTH/4, y = HEIGHT/4, size = 10}
    t5 = {x = 300, y = 200, size = 75}

  --  tween.path(20, strt, {strt, t1, t2, t3, t4,  t5 ,t1})
 --   tween.path(20, strt, {strt, t1, t2, t3, t4,  t5 ,t1, strt})
    tween.path(20, strt, {t1, t2, t3, t4,  t5 ,t1, strt})
 --   tween.path(20, strt, {strt, t1, t2, t3, t4,  t5 ,t1}
 --   , {loop=tween.loop.forever})
end

-- This function gets called once every frame
function draw()
    -- This sets a dark background color
    background(40, 40, 50)

    noFill()
    -- This sets the line thickness
    strokeWidth(2)

    -- The object moved during the path execution
    -- note that even though strt is the final
    -- waypoint the path never seems to return
    -- there
    -- If strt is the first waypoint the path will
    -- start there but, even with a loop, we never
    -- seem to return there

    ellipse(strt.x, strt.y, strt.size)
