Collision Problem with Physics

Hi, i am developing a game which include a player on the way and oncoming obstacles.I want to detect collision between coming obstacles and my player. I set physic like that

local physics = require("physics");
physics.setDrawMode("hybrid");
physics.start();
physics.setGravity(0,0);

object.isFixedRotation = true

Apply that to any object you don't want rotating on collision.

Alternatively make them static sensors.

i already did like you said as you see on the code above but it doesnt detect collision if i set gravity to zero. Maybe it does not work because dynamic bodies of obstacles goes to sleep when gravity is zero even i set isAwake=true ??

Did you try something like this?

1 2	physics.setScale( 21 ) physics.setGravity( 0, 0 ) -- no gravity vector

i solved it just about isSensor return nil if it's initialized only in object's own class.This is not about my code : http://developer.anscamobile.com/reference/index/bodyissensor

it is simply

local function onLocalPreCollision( self, event )
   
  local object = event.other;
  object.isSensor = true;
  print("Collision");
  --Also i can set gravity to  zero..
  end
  player.preCollision = onLocalPreCollision;
  player:addEventListener("preCollision",heroCar);
