Physics polygon type body move

I am having trouble with moving a polygon type physics body.
For example

box = physics.body(POLYGON, vec2(WIDTH/2-100,50), vec2(WIDTH/2+100,50), vec2(WIDTH/2+100,250), vec2(WIDTH/2-100,50))
box.type = STATIC

I was trying to move by changing box.x and box.y value. But the polygon representation on the screen doesn’t move.
Any idea??

Try kinematic instead.

Uhm, try something like this:

-- BoxMove

-- Use this function to perform your initial setup
function setup()
    pdb = PhysicsDebugDraw()
    box = createBox(WIDTH/2,HEIGHT/2,20,20)
    box.type = STATIC

function createBox(x,y,w,h)
    -- polygons are defined by a series of points in counter-clockwise order
    local box = physics.body(POLYGON, vec2(-w/2,h/2), vec2(-w/2,-h/2), vec2(w/2,-h/2), vec2(w/2,h/2))
    box.interpolate = true
    box.x = x
    box.y = y
    box.restitutions = 0.25
    box.sleepingAllowed = false
    return box

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

    -- This sets the line thickness

    -- Do your drawing here

function touched(touch)
    if touch.tapCount == 1 then
        box.x = touch.x
    elseif touch.tapCount == 2 then
        box.y = touch.y


Using the PhysicsDebugDraw from Physics Lab example
