    How to remove a fixture from a body?

    edited February 2013 in General questions
    Hi guys,
    If I make a fixture like this

    local shape = b2.CircleShape.new(0, 0, 40)
    body.fix = body:createFixture{shape = shape, density = 10, restitution = 0.2, friction = 0.1, filter = filter}

    then I can remove it using

    body:destroyFixture(body.fix)

    but how do I destroy it, if I load it from a file as here?

    body.physics = (loadfile "virusA/virusA_collide.lua")().physicsData(1)
    body.physics:addFixture(body, "virA")

    Thanks! )

      @RogerT do you use some physics editor that provides that file?

      amm, ok. which one? :)
      Basically I'm not using any so I still would not know, but what you can do, is to try to print all object/properties/methods underneath to find which object has the :destroyFixture(body.fix) method

      you can use this print_r function
      --recursive print of tables
function print_r (t, indent, done)
  done = done or {}
  indent = indent or ''
  local nextIndent -- Storage for next indentation value
  for key, value in pairs (t) do
    if type (value) == "table" and not done [value] then
      nextIndent = nextIndent or
          (indent .. string.rep(' ',string.len(tostring (key))+2))
          -- Shortcut conditional allocation
      done [value] = true
      print (indent .. "[" .. tostring (key) .. "] => Table {");
      print  (nextIndent .. "{");
      print_r (value, nextIndent .. string.rep(' ',2), done)
      print  (nextIndent .. "}");
    else
      print  (indent .. "[" .. tostring (key) .. "] => " .. tostring (value).."")
    end
  end
end
      And use it like:
      print_r(body)
