But u might get some extra traffic because of this :D Anyway i played a little with values and it seems part of problem is in this part : create_box((sx+ex)/World.RATIO,(sy+ey)/World.RATIO,Math.abs(dist)/World.RATIO,2/30,angle); When i change sx+ex to sx and sy+ey to sy then body its placed where it should be placed, BUT... Bodies are not 1 after another but they are more like half of each inside of other..Not sure how to explain it...I tried reducing width by 2 but it didnt help..

U are dividing positions by 60... I tried to use my RATIO that i use everywhere but it doesn't work, though i get different placements then... Any idea how to make this work? p.s. u really should have that value as constant it would be easier to understand what's happening :p Cheers! I think this could be connected with ratio..

Thank you for this article, because of it i am making new game that will use this concept... Problem is that i am stuck ^^... When i draw on screen and drawing transforms to b2 objects they don't appear exactly where trace of "pen" is, but they appear a little down and to the right.. Closer i draw to the right part of the screen objects move more to the right... I am sure this doesn't have anything with gravity.. What is interesting is that this happens even when update of b2World is not running.. :/ And btw, pause will not be solution since i need to draw objects while b2World is running because i am creating action game that will use this drawing object technique... Thanks in advance for your answer.. Please email me. Cheers, Kristian Hi, there..
