  Basically you can create arc with below function to move this bone. you need to tweak it little

  function drawArc(xc,yc,xradius,yradius,startAngle,endAngle,isFill) if yradius == nil then yradius = xradius end if startAngle == nil then startAngle = 0 end if endAngle == nil then endAngle = 360 end if isFill == nil then isFill = true end local shape = Shape.new() if isFill then shape:setFillStyle(Shape.SOLID, 0xffffff, 0.5) else shape:setLineStyle(3, 0x000000) end shape:beginPath() for i=startAngle,endAngle do if i==1 then shape:moveTo(math.sin(math.rad(i)) * xradius, math.cos(math.rad(i)) * yradius) else shape:lineTo(math.sin(math.rad(i)) * xradius, math.cos(math.rad(i)) * yradius) end end if isFill then shape:closePath() end shape:endPath() shape:setPosition(xc,yc) return shape end

  Hi, Thank you for the reply, I didn't get how to implement it with the image, I don't want that line shown in the video, it was just for illustration. The concept is just like I'm throwing a bone to a dog in Parabolic angle. I can do it using MovieClip but I don't want to use it, I just want to know how to achieve this with single image.
  
  The bone should move in Parabolic angle with 360 degree rotation, some thing like this:

  You just have to make a Sprite and make it move through coding. I made an example:

  local bone = Sprite.new() local boneImg = Bitmap.new(Texture.new("BoneSample.png")) stage:addChild(bone) bone:addChild(boneImg) boneImg:setAnchorPoint(0.5, 0.5) local grav = -15 local velx = -3 local rotvel = -3 local x = 300 local y = 400 local rotation = 0     function enterFrame () grav = grav + 0.3 x = x + velx y = y + grav rotation = rotation + rotvel bone:setRotation(rotation) bone:setPosition(x, y) end   stage:addEventListener(Event.ENTER_FRAME, enterFrame)
