I know, but how can I be using methods of "cpShape" of the returned
userdata, if its lightuserdata..?

how can it still have the same metatable as other lightuserdata

....
  lua_pushlightuserdata(d, a);
  luaL_getmetatable(d, "cpShape");
  lua_setmetatable(d, -2);  -- <----- so now the lightuserdata has a 
different metatable what is it!
....
   eventually pushright is called with lua_pcall



function pushright(a,b)
  bdy=a:getBody()  --  <--- lightuserdata executing getBody ???
  bdy:applyImpulse(cpVect.new(20000,0),cpVect.new()) -- <--- correct 
body returned from lightuserdata ??? how?



Best
Chris
